The Eucharist And The Obligation Of Receiving Holy Communion

 


To My Readers: This week's guest poster, John Gregory, writes about important truths pertaining to the Most Holy Eucharist. We can never ponder enough the truths about the Blessed Sacrament. Please feel free to comment as per usual. If anyone has a specific question or comment for me, I will respond as always, but it may take me a bit longer to do so this week.

God bless you all, my dear readers---Introibo

The Form, Matter, and Rites of the Holy Eucharist, and The Obligation Of Receiving Holy Communion

By John Gregory

Constituent Parts of the Eucharist 

THE MATTER 

It is particularly incumbent on pastors to know the matter of this Sacrament, in order that they themselves may rightly consecrate it, and also that they may be able to instruct the faithful as to its significance, inflaming them with an earnest desire of that which it signifies. 

THE FIRST ELEMENT OF THE EUCHARIST IS BREAD 

The matter of this Sacrament is twofold.  The first element of wheaten bread, of which we shall now speak.  Of the second we shall treat hereafter.  As the Evangelists, Mathew, Mark and Luke testify, Christ the Lord took bread into His hands, blessed, and brake, saying: This is my body; (Matthew 26: 26; Mark 14: 22; Luke 22: 19) and, according to John, the same Saviour called Himself bread in these words: I am the living bread, that came down from heaven. (John 6: 41). 

THE SACRAMENTAL BREAD MUST BE WHEATEN 

Theare are, however, various sorts of bread, either because they consist of different materials,—such as wheat, barley, pulse and other products of the earth; or because they posses different qualities,—some being leavened, others altogether without leaven.  It is to be observed that, with regard to the former kinds, the words of the Saviour show that the bread should be wheaten; for, according to common usage, when we simply say bread, we are sufficiently understood to mean wheaten bread.  This is also declared by a figure in the Old Testament, because the Lord commanded that the loaves of proposition which signified this Sacrament, should be made of fine flour. (Leviticus 24: 5) 

THE SACRAMENTAL BREAD SHOULD BE UNLEAVENED 

But as wheaten bread alone is to be considered the proper matter for this Sacrament—a doctrine which has been handed down by Apostolic tradition and confirmed by the authority of the Catholic Church—it may be easily inferred from the doings of Christ the Lord that this bread should be unleavened.  It was consecrated and instituted by Him on the first day of unleavened bread, on which it was not lawful for the Jews to have anything leavened in their houses. (Matthew 27: 17; Mark 14: 12; Luke 22: 7) 

Should the authority of John the Evangelist, (John 13: 1) who says that all this was done before the feast of the Passover, be objected to, the argument is one of easy solution.  For by the day before the pasch John understands the same day which the other Evangelists designate as the first day of unleavened bread. He wished particularly to mark the natural day, which commences at sunrise; whereas they wanted to point out that our Lord celebrated the Pach on Thursday evening just when the days of the unleavened bread were beginning.  Hence Saint Chrysostom also understands the first day of unleavened bread to be the day on the evening of which unleavened bread was to be eaten. [For an explanation of the time when our Lord kept His last Pasch and instituted the Holy Eucharist see Callan, The four Gospels, pages 167-171.] 

The peculiar suitableness of the consecration of unleavened bread to express that integrity and purity of mind which the faithful should bring to this Sacrament we learn from these words of the Apostle: Purge out the old leaven that you may be a new paste, as you are unleavened.   For Christ our Passover is sacrificed.  Therefore, let us feast, not with the old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth. (1 Corinthians 5: 7) 

UNLEAVENED BREAD NOT ESSENTIAL 

This quality of the bread, however, is not to be deemed so essential that, if it be wanting, the Sacrament cannot exist; for both kinds are called by the one name and have the true and proper nature of bread.  No one, however, is at liberty on his own private authority, or rather presumption, to transgress the laudable rite of his Church.  And such departure is the less warrantable in priests of the Latin Church, expressly obliged as they are by the supreme Pontiffs, to consecrate the sacred mysteries with unleavened bread only. 

QUANITY OF THE BREAD 

With regard to the first matter of this Sacrament, let this exposition suffice.  It is, however, to be observed, that the quantity of the matter to be consecrated is not defined, since we cannot define the exact number of those who can or ought to receive the sacred mysteries. 

THE SECOND ELEMENT OF THE EUCHARIST IS WINE 

It remains for us to treat of the other matter and element of this Sacrament, which is wine pressed from the fruit of the vine, with which is mingled a little water. 

That in the institution of this Sacrament our Lord and Saviour made use of wine has been at all times the doctrine of the Catholic Church, for He Himself said: I will not drink from henceforth of this fruit of the vine until that day. (Matthew 26: 29; Mark 14: 25) On this passage Chrysostom observes: He says, "Of the fruit of the vine," which certainly produced wine not water; as if he had it in view, even at so early a period, to uproot the heresy which asserted that in these mysteries water alone is to be used. 

WATER SHOULD BE MIXED WITH THE WINE 

With the wine, however, the Church of God has always mingled water.  First, because Christ the Lord did so, as is proved by the authority of Councils and the testimony of Saint Cyprian; next, because by this mixture is renewed the recollection of the blood and water that issued from His side, Walters, also, as we read in the Apocalypse, (Apocalypse 17: 15) signify the people; and hence, water mixed with the wine signifies the union of the faithful with Christ their Head.  This rite, derived as it is from Apostolic tradition, the Catholic Church has always observed.

 But although there are reasons so grave for mingling water with the wine that it cannot be omitted without incurring the guilt of mortal sin, yet its omission does not render the Sacrament null. 

Again as in the sacred mysteries priests must be mindful to mingle water with wine, so, also, must they take care to mingle it in small quantity, for, in the opinion and judgment of the ecclesiastical writers, that water is changed into wine.  Hence these words of Pope Honorius on the subject: A pernicious abuse has prevailed in your district of using in the sacrifice a greater quantity of water than of wine; whereas, according to the rational practice of the universal Church, the wine should be used in much greater quantity than the water. 

NO OTHER ELEMENTS PERTAIN TO THIS SACRAMENT 

These, then, are the only two elements of this Sacrament; and with reason has it been enacted by many decrees that, although there have been those who were not afraid to do so, it is unlawful to offer anything but bread and wine. 

PECULIAR FITNESS OF BREAD AND WINE 

We have now to consider the aptitude of these two symbols of bread and wine to represent those things of which we believe and confess they are the sensible signs. 

In the first place, then, they signify to us Christ, as the true life of men; for our Lord Himself says: My flesh is meat indeed, and my blood is drink indeed.  (John 6: 55) As, then, the body of Christ the Lord furnishes nourishment unto eternal life to those who receive this Sacrament with purity and holiness, rightly is the matter composed chiefly of those elements by which our present life is sustained, in order that the faithful may easily understand that the mind and soul are satiated by the Communion of the precious body and blood of Christ.  

These very elements serve also somewhat to suggest to men the truth of the Real Presence of the body and blood of the Lord in the Sacrament.  Observing, as we do, that bread and wine are every day changed by the power of nature into human flesh and blood, we are led the more easily by this analogy to believe that the substance of the bread and wine is changed, by the heavenly benediction, into the real flesh and real blood of Christ. 

This admirable change of the elements also helps to shadow forth what takes place in the soul.  Although no change of the bread and wine appears externally, yet their substance is truly changed into the flesh and blood of Christ; so, in like manner, although in us nothing appears changed, yet we are renewed inwardly unto life, when we receive in the Sacrament of the Eucharist the true life. 

Moreover, the body of the Church, which is one, consists of many members, and of this union nothing is more strikingly illustrative than the elements of bread and wine; for bread is made from many grains and wine is pressed from many clusters of grapes.  Thus they signify that we, though many, are most closely bound together by the bond of this divine mystery and made, as it were, one body. 

Form of the Eucharist 

 The form to be used in the consecration of the bread is next to be treated of, not, however, in order that the faithful should be taught these mysteries, unless necessity require it; for this knowledge is not needful for those who have not received Holy Orders.  The purpose (of this section) is to guard against most shameful mistakes on the part of priests, at the time of the consecration, due to ignorance of the form. 

FORM TO BE USED IN THE CONSECRATION OF THE BREAD 

We are then taught by the holy Evangelists, Matthew and Luke, and also by the Apostle, that the form consists of these words: This is my body; for it is written: Whilst they were at supper, Jesus took bread, and blessed it, and brake, and gave to his disciples, and said: Take and eat, This is my body. (Matthew 26: 26; Mark 14: 22; Luke 22: 19; 1 Corinthians 11: 24) This form of consecration having been observed by Christ the Lord has been always used by the Catholic Church.  The testimonies of the Fathers, the enumeration of which would be endless, and also the decree of the Council of Florence, which is well known and accessible to all, must here be omitted, especially as the knowledge which they convey may be obtained from these words of the Saviour: Do this for a commemoration of me. (Luke 22: 19) For what the Lord enjoined was not only what He had done, but also what he had said; and especially is this true, since the words were uttered not only to signify, but also to accomplish. 

That these words constitute the form is easily proved from reason also.  The form is that which signifies what is accomplished in this Sacrament; but as the preceding words signify and declare what takes place in the Eucharist, that is, the conversion of the bread into the true body of our Lord, it therefore follows that these very words constitute the form.  In this sense may be understood the words of the Evangelist: He blessed; for they seem equivalent to this: Taking bread, he blessed it, saying: "This is my body." (Matthew 26: 26) 

NOT ALL THE WORDS USED ARE ESSENTIAL 

Although in the Evangelist the words, Take and eat, precede the words (This is my body), they evidently express the use only, not the consecration, of the matter.  Wherefore, while they are not necessary to the consecration of the Sacrament, they are by all means to be pronounced by the priest, as is also the conjunction for in the consecration of the body and blood.  But they are not necessary to the validity of the Sacrament, otherwise it would follow that, if this Sacrament were not to be administered to anyone, it should not, or indeed could not, be consecrated; whereas, no one can lawfully doubt that the priest, by pronouncing the words of our Lord according to the institution and practice of the Church, truly consecrates the proper matter of the bread, even though it should afterwards never be administered. 

FORM TO BE USED IN THE CONSECRATION OF THE WINE 

With regard to the consecration of the wine, which is the other element of this Sacrament, the priest, for the reason we have already assigned, ought of necessity to be well acquainted with, and well understand its form.  We are then firmly to believe that it consists in the following words: This is the chalice of my blood, of the new and eternal testament, the mystery of faith, which shall be shed for you and for many, to the remission of sins.  Of these words the greater part are taken from Scripture; but some have been preserved in the Church from Apostolic tradition 

Thus the words, this is the chalice, are found in Saint Luke and in the Apostle; (Luke 12: 20; 1 Corinthians 11: 25) but the words that immediately follow, of my blood, or my blood of the new testament, which shall be shed for you and for many to the remission of sins, are found partly in Saint Luke and Partly in Saint Matthew. (Luke 22: 20; Matthew 26: 28) But the words, eternal, and the mystery of faith, have been taught us by holy tradition, the interpreter and keeper of Catholic truth. 

Concerning this form no one can doubt, if he here also attend to what has been already said about the form used in the consecration of the bread.  The form to be used (in the consecration) of this element, evidently consists of those words which signify that the substance of the wine is changed into the blood of our Lord.  Since therefore, the words already cited clearly declare this, it is plain that no other words constitute the form. 

They moreover express certain admirable fruits of the blood shed in the Passion of our Lord, fruits which pertain in a most special manner to this Sacrament.  Of these, one is access to the eternal inheritance, which has come to us by right of the new and everlasting testament. Another is access to righteousness by the mystery of faith; for God hath set forth Jesus to be a propitiator through faith in his blood, that he himself may be just, and the justifier of him, who is of the faith of Jesus Christ. (Romans 3: 25) A third effect is the remission of sins. 

EXPLANATION OF THE FORM USED IN THE CONSECRATION OF THE WINE 

Since these very words of consecration are replete with mysteries and most appropriately suitable to the subject, they demand a more minute consideration. 

The words: This is the chalice of my blood, are to be understood to mean: This is my blood, which is contained in this chalice.  The mention of the chalice made at the consecration of the blood is right and appropriate, inasmuch as the blood is the drink of the faithful, and this would not be sufficiently signified if it were not contained in some drinking vessel. 

Next follow the words: Of the new testament.  These have been added that we might understand the blood of Christ the Lord to be given not under a figure, as was done in the Old Law, of which we read in the Epistle to the Hebrews (9: 18) that without blood a testament is not dedicated; but to be given to men in truth and in reality, as becomes the New Testament.  Hence the Apostle says: Christ therefore is the mediator of the new testament, that by means of his death, they who are called may receive the promise of eternal inheritance. (Hebrews 9: 15) 

The word eternal refers to the eternal inheritance, the right to which we acquire by the death of Christ the Lord, the eternal testator. 

The words mystery of faith, which are subjoined, do not exclude the reality, but signify that what lies hidden and concealed and far removed from the perception of the eye, is to be believed with firm faith.  In this passage, however, these words bear a meaning different from that which they have when applied also to Baptism.  Here the mystery of faith consists in seeing by faith the blood of Christ veiled under the species of wine; but Baptism is justly called by us the Sacrament of faith, by the Greeks, the mystery of faith, because it embraces the entire profession of the Christian faith. 

Another reason why we call the blood of the Lord the mystery of faith is that human reason is particularly beset with difficulty and embarrassment when faith proposes to our belief that Christ the Lord, the true Son of God, at once God and man, suffered death for us, and this death is designated by the Sacrament of His blood. 

Here, therefore, rather than at the consecration of His body, is appropriately commemorated the Passion of our Lord, by the words, which shall be shed for the remission of sins. For the blood, separately consecrated, serves to place before the eyes of all, in a more forcible manner, the Passion of our Lord, His death, and the nature of His sufferings. 

The additional words for you and for many, are taken, some from Matthew, some from Luke, (Matthew 26: 28; Luke 22: 20) but were joined together by the Catholic Church under the guidance of the Spirit of God.  They serve to declare the fruit and advantage of His Passion.  For if we look to its value, we must confess that the Redeemer shed His blood for the salvation of all; but if we look to the fruit which mankind have received from it, we shall easily find that it pertains not unto all, but to many of the human race.  When therefore (our Lord) said: For you, He meant either those who were present, or those chosen from among the Jewish people, such as were, with the exception of Judas, the disciples with whom He was speaking.  When He added, And for many, He wished to be understood to mean the remainder of the elect from among the Jews or Gentiles. 

With reason, therefore, were the words for all not used, as in this place the fruits of the Passion are alone spoken of, and to the elect only did His Passion bring the fruit of salvation.  And this is the purport of the Apostle (Hebrews 9: 28) when he says: Christ was offered once to exhaust the sins of many; and also of the words of our Lord in John: I pray for them; I pray not for the world, but for them whom thou hast given me, because they are thine. (John 17: 9) 

Beneath the words of this consecration lie hid many other mysteries, which by frequent meditation and study of sacred things, pastors will find it easy, with the divine assistance, to discover for themselves.  (Catechism of Trent [CoT] pages 219 - 225) 

The Obligation of Receiving the Eucharist 

Jesus took the loaves, and when he had given thanks, he distributed to them that were sat down (John 6: 11) 

HOW OFTEN MUST COMMUNION BE RECEIVED? 

Lest any be kept away from Communion by the fear that the requisite preparation is too hard and laborious, the faithful are frequently to b reminded that they are all bound to receive the Holy Eucharist.  Furthermore, the Church has decreed that whoever neglects to approach Holy Communion once a year, at Easter, is liable to sentence of excommunication.  [This was decreed in the Fourth Lateran Council, 1215.  In the New Cod it is found in can. 859.] 

THE CHURCH DESIRES THE FAITHFUL TO COMMUNICATE DAILY 

However, let not the faithful imagine that it is enough to receive the body of the Lord once a year only, in obedience to the decree of the Church.  They should approach oftener; but whether monthly, weekly, or daily, cannot be decided by one fixed universal rule.  Saint Augustine, however, lays down a most certain norm: Live in such a manner as to be able to receive every day. 

It will therefore be the duty of the pastor frequently to admonish the faithful that, as they deem it necessary to afford daily nutriment to the body, they should also feel solicitous to feed and nourish the soul every day with this heavenly food.  It is clear that the soul stands not less in need of spiritual, than the body of corporal food.  Here it will be found most useful to recall the inestimable and divine advantages which, as we have already shown, flow from sacramental Communion.  It will be well also to refer to the manna, which was a figure (of this Sacrament), and which refreshed the bodily powers every day.  (Exodus 16: 21, 22, 4) The Fathers who earnestly recommended the frequent reception of this Sacrament may also be cited.  The words of Saint Augustine, Thou sinnest daily, receive daily, express not his opinion only, but that of all the Fathers who have written on the subject, as anyone may easily discover who will carefully read them. [Frequent Communion is recommended by the following: Augustine, Ignatius, Basil, Cyril, and others at the time this Catechism was first published in 1566] 

That there was a time when the faithful approached Holy Communion every day we learn from the Acts of the Apostles.  All who then professed the faith of Christ burned with such true and sincere charity that, devoting themselves to prayer and other works of piety (Acts 2: 42, 46), they were found prepared to communicate daily.  This devout practice, which seems to have been interrupted for a time, was again partially revived by the holy Pope and martyr Anacletus, who commanded that all the ministers who assisted at the Sacrifice of the Mass should communicate—an ordinance, as the Pontiff declares, of Apostolic institution.  It was also for a long time the practice of the Church that, as soon as the Sacrifice was complete, and when the priest himself had communicated, he turned to the congregation and invited the faithful to the Holy Table in these words: Come, brethren, and receive Communion; and thereupon those who were prepared advanced to receive the holy mysteries with the most fervent devotion. 

THE CHURCH COMMANDS THE FAITHFUL TO COMMUNICATE ONCE A YEAR 

But subsequently, when charity and devotion had grown so cold that the faithful very seldom approached Communion, it was decreed by Pope Fabian [236 – 250], that all should communicate thrice every year, at Christmas, at Easter and at Pentecost.  This decree was afterwards confirmed by many Councils, particularly by the first of Agde. 

Such at length was the decay of piety that not only was this holy and salutary law unobserved, but Communion was deferred for years.  The Council of Lateran, therefore, decreed that all the faithful should receive the sacred body of the Lord, at least once a year, at Easter, and that neglect of this duty should b chastised by exclusion from the society of the faithful. 

WHO ARE OBLIGHED BY THE LAW OF COMMUNION 

But although this law, sanctioned by the authority of God and of His Church, concerns all the faithful, it should be taught that it does not extend to those who on account of their tender age have not attained the use of reason.  For these are not able to distinguish the Holy Eucharist from common and ordinary bread and cannot bring with them to this Sacrament piety and devotion. Furthermore (to extend the precept to them) would appear inconsistent with the ordinance of our Lord, for He said Take and eat (Matthew 26:26)—words which cannot apply to infants, who are evidently incapable of taking and eating. 

In some places, it is true, an ancient practice prevailed of giving the Holy Eucharist even to infants; but, for the reasons already assigned, and for other reasons in keeping with Christian piety, this practice has been long discontinued by the authority of the Church. 

With regard to the age at which children should be given the holy mysteries, this the parents and confessor can best determine.  To them it belongs to inquire and to ascertain from the children themselves whether they have some knowledge of this admirable Sacrament and whether they desire to receive it. [Regarding the Communion of children see Code, can. 854] 

Communion must not be given to persons who are insane and incapable of devotion.  However, according to the decree of the Council of Carthage, it may be administered to them at the close of life, provided they have shown, before losing their minds, a pious and religious disposition, and no danger, arising from the state of the stomach or other inconvenience or disrespect, is likely. (CoT pages 249 – 251) 

Conclusion

The Most Holy Eucharist is the flesh and blood of God.  Pause a moment and let that resonate a bit.  The whole purpose of our existence is to know, love, and serve God in this life so that we may be happy with Him forever in the next.  Salvation is everything.  Christ did so much to make it possible to be saved, but we must do the rest.  He doesn't give us a free ride.  But due to our fallen human nature (Original Sin), salvation is impossible apart from the grace of God and difficult with it.  This should motivate us to do everything we can to ensure our eternal salvation such as always being in the state of grace and receiving the Eucharist devoutly as often as possible as the great Saint Augustine alluded to.  When we receive the Eucharist daily with devotion, we are storing treasures and increasing the grace of God within us, fortifying our souls against future temptations and enabling us to fight the good fight until the end, persevering in the state of sanctifying grace until our dying breaths.  Is there anything more we should demand from the Lord before we start acting as we should?

Contending For The Faith---Part 57

 

In St. Jude 1:3, we read, "Dearly beloved, taking all care to write unto you concerning your common salvation, I was under a necessity to write unto you: to beseech you to contend earnestly for the faith once delivered to the saints." [Emphasis mine]. Contending For The Faith is a series of posts dedicated to apologetics (i.e.,  the intellectual defense of the truth of the Traditional Catholic Faith) to be published the first Monday of each month.  This is the next installment.

Sadly, in this time of Great Apostasy, the faith is under attack like never before, and many Traditionalists don't know their faith well enough to defend it. Remember the words of our first pope, "But in your hearts revere Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect..." (1Peter 3:16). There are five (5) categories of attacks that will be dealt with in these posts. Attacks against:
  • The existence and attributes of God
  • The truth of the One True Church established by Christ for the salvation of all 
  • The truth of a particular dogma or doctrine of the Church
  • The truth of Catholic moral teaching
  • The truth of the sedevacantist position as the only Catholic solution to what has happened since Vatican II 
In addition, controversial topics touching on the Faith will sometimes be featured, so that the problem and possible solutions may be better understood. If anyone had suggestions for topics that would fall into any of these categories, you may post them in the comments. I cannot guarantee a post on each one, but each will be carefully considered.

***N.B. Special Note To My Readers: I ask you all in charity to please pray for the mother of one of my long-time readers---Poni. Her mom is seriously ill and needs our prayers for a full return to health and resignation to the Will of God. Please say a special prayer for Poni's mother and for Poni herself, that God may give her strength during this most trying and sorrowful time.

God bless you all, my dear readers---Introibo

Proofs of the Resurrection: Debunking the Conspiracy Hypothesis
There are numerous attempts by the enemies of Christ to deny His physical resurrection from the dead. There are four (4) basic arguments to explain away Christ's resurrection: (1) it was a hallucination of the Apostles; (2) the Apostles created a myth-- they did not mean what they taught to be literal; (3) the Apostles conspired to deceive the world; and (4) Christ didn't really die, he "swooned" and later fully recovered. 

In this post, I will refute the so-called "Conspiracy Hypothesis." (N.B. The information contained in this post comes from myriad sources, both in print and online. I take no credit other than condensing the material into a terse and readable post---Introibo). 

What is The Conspiracy Hypothesis?
The Conspiracy Hypothesis against the resurrection of Christ is also known as the stolen body hypothesis. It claims that Jesus Christ did not rise from the dead, and that His body was instead secretly removed from the tomb by His disciples, who then fabricated the story of a resurrection. According to the Gospel of Saint Matthew (St. Matthew 28:11–15), when the tomb was found empty, the chief priests and elders bribed the Roman guards on duty, telling them to say: "His disciples came by night and stole Him away while we were asleep."

This narrative is one of the earliest recorded alternative explanations to the resurrection, used by critics of Christianity (most notably the Jews) in antiquity to account for the missing Body. Why would Christ's followers steal the Body of Our Lord and conspire to lie about Him rising from the dead? Several reasons are advanced:

• Fulfill Christ's Predictions: They would fabricate a scenario that matched Jesus's earlier prophecies that He would rise after three days. They didn't want to be humiliated that the One they followed did not have His predictions come true. 

• Maintain the Movement: Keep their messianic hopes, authority, or movement alive after the demoralizing shock of His public crucifixion.

• Pious Deceit: Perpetuate a "noble lie" out of devotion or a desire to promote Christ's ethical teachings

The Conspiracy Hypothesis is demonstrably false.

What Constitutes Evidence for Historians?
Historians weigh various factors in assessing competing hypotheses. Some of the most important are as follows:

1.  The best explanation will have greater explanatory scope than other explanations. That is, it will explain more of the evidence.

2.  The best explanation will have greater explanatory power than other explanations. That is, it will make the evidence more probable.

3. The best explanation will be more plausible than other explanations. That is, it will fit better with true background beliefs.

4. The best explanation will be less contrived than other explanations. That is, it won’t require adopting as many new beliefs which have no independent evidence.

5. The best explanation will be disconfirmed by fewer accepted beliefs than other explanations. That is, it won’t conflict with as many accepted beliefs.

6. The best explanation will meet conditions (1)-(5) so much better than the others that there’s little chance that one of the other explanations, after further investigation, will do better in meeting these conditions.

(See C. Behan McCullagh, Justifying Historical Descriptions [1984], pg. 19; Emphasis in original). 

Since a hypothesis may do really well in meeting some conditions but not so well in meeting others, figuring out which hypothesis is the best explanation may often be difficult and requires skill. However, if the explanatory scope and power of a hypothesis are very great, so that it does a much better job in explaining a wide variety of facts, then it’s likely to be the true explanation.

So let’s apply these tests to the typical hypotheses which have been offered down through history to explain the empty tomb, post-mortem appearances, and origin of the disciples’ belief in Jesus’ resurrection, and let’s see if they do better or as well in explaining these facts as the dogma of the Resurrection. 

According to this hypothesis, the disciples stole the body of Jesus and lied about his appearances, thus faking the resurrection. This was the very first counter-explanation for the empty tomb, as we’ve seen, and it was revived during the eighteenth century by European  Deists. Today, however, this explanation has been completely given up by modern scholarship.  We can see why when we assess it by the standard criteria for testing historical hypotheses.

1. Explanatory scope.  The Conspiracy Hypothesis does seem to cover the full scope of the evidence, for it offers explanations of the empty tomb (the disciples stole the body), the post-mortem appearances (the disciples lied about seeing Jesus), and the origin of the disciples’ (supposed) belief in Jesus’ resurrection (again, they lied).

2. Explanatory power.  How probable is the evidence, given the Conspiracy Hypothesis?  Here doubts begin to arise about the adequacy of the hypothesis. 

First, consider the story of the empty tomb.  If the disciples stole Jesus’ corpse, then it would be utterly pointless to fabricate a story about women finding the tomb to be empty.  Such a story would not be the sort of tale Jewish men would invent.  Moreover, the simplicity of the story is not what one would expect, given the Conspiracy Hypothesis—where are the Scriptural proof-texts, the evidence of fulfilled prophecy?  Why isn’t Jesus described as emerging from the tomb, as in later forgeries like the so-called "Gospel of Peter"?  Neither is the dispute with non-believing Jews well-explained.  Why isn’t St. Matthew’s guard already there in St. Mark’s story?  Even in St. Matthew’s story the guard is set too late: the body could have already been stolen before the guard arrived on Saturday morning, so that they were guarding, unbeknownst to them, an empty tomb!  For a failsafe alibi against theft of the body, see again the forged Gospel of Peter, where the guard is set immediately upon interment of the corpse. 

As for the appearance stories, similar problems arise.  A fabricator would probably describe Jesus’ resurrection appearances in terms of Old Testament visions of God and descriptions of the end-time resurrection (as in Daniel 12.2).  But then Jesus should appear to the disciples in dazzling glory.  And why not a description of the resurrection itself?  Why no appearances to Caiaphas the high priest or to the villains on the Sanhedrin, as Jesus predicted?  They could be then branded as the real liars for denying that Jesus did appear to them! 

However, the explanatory power of the Conspiracy Hypothesis is undoubtedly weakest when it comes to the origin of the disciples’ belief in Jesus’ resurrection.  For the hypothesis is really a denial of that fact; it seeks to explain the mere semblance of belief on the disciples’ part.  But as critics have universally recognized, you can’t plausibly deny that the earliest disciples at least sincerely believed that Jesus was risen from the dead. They staked their very lives on that conviction.  The transformation in the lives of the disciples is not credibly explained by the hypothesis of a conspiracy.  This shortcoming alone has been enough in the minds of most scholars to sink the old Conspiracy Hypothesis forever.

3. Plausibility.  The real Achilles’ Heel of the Conspiracy Hypothesis is, however, its implausibility.  One might mention here objections to the unbelievable complexity of such a conspiracy or the supposed psychological state of the disciples; but the overriding problem that dwarfs all others is that it is wholly anachronistic to suppose that first century Jews intended to hoax Jesus’ resurrection.  The Conspiracy Hypothesis views the disciples’ situation through the rearview mirror of Christian history rather than through the eyes of a first century Jew. 

In the first place, there was no expectation in Judaism of a Messiah who, instead of establishing David’s throne and subduing Israel’s enemies, would be shamefully executed by the Gentiles as a criminal.  Moreover, the Jewish idea of resurrection was just unconnected with the idea of Messiah and even incompatible with it, since Messiah was not supposed to be killed.  As N. T. Wright nicely puts it, if you’re a first century Jew, and your favorite Messiah got himself crucified, then you’ve basically got two choices: either you go home or else you get yourself a new Messiah.

Secondly, the Jewish conception of resurrection of the dead differed in at least two fundamental respects from the resurrection of Jesus.

 It is a fact that in Jewish thinking the resurrection to glory and immortality always occurred after the end of the world.  Jews had no idea of a resurrection within history. That’s why, I think, the disciples had so much trouble understanding Jesus’ predictions of his own resurrection. They thought he was talking about the resurrection at the end of the world. Look at St. Mark 9:9-11, for example:

And as they were coming down from the mountain, He gave them orders not to relate to anyone what they had seen, until the Son of Man should rise from the dead. And they seized upon that statement, discussing with one another what rising from the dead might mean. And they began questioning Him, saying, “Why is it that the scribes say that first Elijah must come?”

Here Jesus predicts His resurrection, and what do the disciples ask? “Why is it that the scribes say that first Elijah must come?” In first century Judaism it was believed the prophet Elijah would come again before the great and terrible Day of the Lord, the judgment day when the dead would be raised. The disciples could not understand the idea of a resurrection occurring within history prior to the end of the world. Hence, Jesus’ predictions only confused them.

Thus, given the Jewish conception of the resurrection, the disciples after Jesus’ crucifixion would not have come up with the strange idea that he had been already raised. They would in all probability have looked forward to the resurrection at the last day and, in keeping with Jewish custom, perhaps preserved his tomb as a shrine where his bones could rest until the resurrection.

Secondly, in Jewish thinking the resurrection was always the resurrection of all the righteous dead.  Jews had no idea of the resurrection of an isolated individual apart from the general resurrection. Moreover, there was simply no connection between the individual believer’s resurrection and the prior resurrection of the Messiah.  That’s why we find no examples of other failed messianic movements claiming that their executed leader was risen from the dead. 

First century Jews had no idea of the resurrection of an isolated individual, especially of the Messiah, in advance of the general resurrection at the end of the world.  So the idea of stealing Jesus’ corpse and saying that God had raised him from the dead is hardly one that would have entered the minds of these Jewish disciples of Jesus nor seemed to them a plausible strategy for evangelizing their fellow Jews!

What about influences from outside Judaism?  A suggestion widespread on the Internet today is that early Christians came up with the idea of Jesus’ resurrection through the influence of pagan mythology.  This suggestion is an old one.  Back around the turn of the 19th to the 20th century, scholars in comparative religion collected parallels to Christian beliefs in other religious movements, and some even thought to explain Christian beliefs, including the belief in Jesus’ resurrection, as the result of the influence of such myths. The movement soon collapsed, however, principally due to two factors:

(a) Scholars came to realize that the parallels are false.  The ancient world was a virtual fruit basket of myths of various gods and heroes.  Comparative studies in religion require sensitivity to their similarities and differences, or distortion and confusion inevitably result.  Unfortunately, those who were eager to find parallels to Jesus’ resurrection failed to exercise such sensitivity. 

Many of the alleged parallels are actually stories of the assumption of the hero into heaven (Hercules, Romulus).  Others are disappearance stories, which claim that the hero has vanished into a higher sphere (Apollonius of Tyana, Empedocles).  Still others are seasonal symbols for the crop cycle, as the vegetation dies in the dry season and comes back to life in the rainy season (Tammuz, Osiris, Adonis). Some are political expressions of Emperor worship (Julius Caesar, Caesar Augustus).

None of these ideas is parallel to the Jewish idea of the resurrection of the dead.  Indeed, most scholars have come to doubt whether, properly speaking, there really were any myths of dying and rising gods at all. For example, in the myth of Osiris, which was one of the best known symbolic seasonal myths, Osiris doesn’t really come back to life but simply continues to exist in the realm of the dead. 

Scholars have come to realize that pagan mythology is simply the wrong interpretive context for understanding Jesus of Nazareth. Jesus and his disciples were first century Israelite Jews, and it is against that background that they must be understood.  The collapse of the alleged parallels is just one indication that pagan mythology is the wrong interpretive context for understanding the disciples’ belief in Jesus’ resurrection.

(b) There is in any case no causal connection between the pagan myths and the origin of the disciples’ belief in Jesus’ resurrection.  Jews were familiar with the seasonal pagan deities (Ezekiel 8.14-15) and found them abhorrent.  That’s why there is no trace of cults of dying and rising gods at all in first century Israel.  It’s pretty unlikely that the original disciples would have come up with the idea that Jesus of Nazareth was risen from the dead because they had heard pagan myths about dying and rising seasonal deities. So scholars have universally abandoned this approach.  Internet sceptics are over 100 years out of date.

Notice that this criticism undermines not only conspiracy theories, which suppose that the disciples insincerely proclaimed Jesus’ resurrection, but also any theory which suggests that, on the basis of pagan or Jewish influences, they sincerely came to believe in and preached his resurrection.

4. Less contrived.  Like all conspiracy theories of history, the Conspiracy Hypothesis is contrived in supposing that what all the evidence seems to point to is, in fact, mere appearance only, to be explained away by hypotheses for which there is no evidence.  Specifically, it postulates motives and ideas in the minds of the earliest disciples and actions on their part for which there is not a shred of evidence.  It can become even more contrived, as hypotheses have to be multiplied to deal with objections to the theory, for example, how to account for the appearance to the 500 brethren or the women’s role in the empty tomb and appearance stories.

5. Disconfirmed by fewer accepted beliefs.  The Conspiracy Hypothesis tends to be disconfirmed by our general knowledge of conspiracies, their instability and tendency to unravel.  Moreover, it is disconfirmed by accepted beliefs such as the sincerity of the disciples, the nature of first century Jewish messianic expectations, and so on.

6. Exceeds other hypotheses in fulfilling conditions (1)-(5).  This condition is obviously not met, since there are better hypotheses (such as the Hallucination Hypothesis), which don’t dismiss the disciples’ belief in Jesus’ resurrection as a blatant lie.

No scholar would defend the Conspiracy Hypothesis today. The only place you read about such things is in the popular, sensationalist press or on the Internet.

Conclusion

The Conspiracy Hypothesis has no plausibility. Consider the Apostles behavior after the resurrection. The change in their lives from fear to faith, despair to confidence, confusion to certitude, runaway cowardice to steadfast boldness under threat and persecution, not only proves their sincerity but testifies to some powerful cause of it. Can a lie cause such a transformation? Obviously not. The physical resurrection of Jesus Christ from the dead is a fact of history and not some conspiratorial fraud.

Mortal Sin Or Material Error: The Una Cum Verdict The Church Already Rendered

 


To My Readers: This week's post by guest poster Ozon goes into the "Una Cum" controversy. His post is very well-written and has excellent citations. As my regular readers know, I believe the so-called Una Cum is licit to attend. See my comprehensive post on the topic of Una Cum here: introiboadaltaredei2.blogspot.com/2023/03/undeclared-heretics.html.

I am in basic agreement with Ozon's conclusion. He approaches the problem from a slightly different angle than I do, but I think it's definitely further confirmation that the "Una Cum Mass" is not off limits for Traditionalists. I also maintain that if you feel you cannot attend Una Cum in good conscience, you shouldn't. 

Please feel free to comment as usual. If you have a specific question or comment for me, I will answer as always, but it may take me a bit longer to do so this week.

God bless you all, my dear readers---Introibo

Mortal Sin Or Material Error: The Una Cum Verdict The Church Already Rendered

By Ozon

Part I: The Sunday Morning Dilemma

It is 7:45 AM on a cold, overcast Sunday morning.

An old station wagon sits idling in an empty parking lot three miles outside of town. The engine hums. The heater rattles. And inside that car, a father of five grips the steering wheel so hard his knuckles have gone white.

His wife sits beside him, quiet, her thumb holding page 625 of a well worn 1962 St. Andrew Daily Missal. She has not turned that page in four minutes.

In the back seat, five children. Dressed. Groomed. Silent. Not fidgeting. Not fighting. That alone tells you something is wrong.

This family has already driven past three local diocesan parishes to reach this gravel lot. That part was easy. Every traditional Catholic makes the same calculation on Sunday morning: bypass the guitar Masses, the felt banners, the liturgical experiments, and head for the chapel where the Faith is preserved intact.

But the agonizing decision is what waits five minutes down this two lane county road.

A traditional Latin Mass chapel. Silk vestments. Gregorian chant rising toward oak rafters. The Roman Canon whispered with exquisite precision by a validly ordained, deeply reverent Catholic priest.

Everything this father has fought to give his family.

Yet he cannot bring himself to put the car in drive.

Why?

Because forty minutes into that Mass, after the Confiteor, after the Introit, after the Gloria, the priest will bow low over the altar cloth, trace three signs of the cross above the bread and chalice, and murmur seven Latin words during the Te Igitur:

"...una cum fámulo tuo Papa nostro Leone..."

("...together with Thy servant Leo, our Pope...")

Seven words. Spoken in a whisper. Heard by almost no one in the nave.

To ninety nine percent of the Christian world, that phrase is completely invisible, a liturgical technicality buried inside the most ancient prayer in Western Christendom.

But inside the passionate, fractured world of traditional Catholicism, those seven words are an ecclesiastical fault line. They have torn families apart. Ended lifelong friendships. Driven wedges between priest and penitent, husband and wife, father and son. And right now, in that gravel parking lot, they are determining where this man's conscience will spend its Sunday.

He is caught in the crosshairs of a ruthless theological war. And every side is aiming at his soul:

In Camp A, an influential online polemicist and an independent priest have warned him, in writing, in public, in terms that admit no ambiguity, that crossing that chapel door makes him an objective traitor to the Catholic Faith. Their argument is blunt:

"To assist at an 'Una Cum' Mass naming a notorious heretic is to burn a pinch of incense to Caesar. You are offering sacrifice in union with apostasy. It is a mortal sin of illicit communicatio in sacris. Stay home. Lock your door. Pray the Rosary on your knees."

To this camp, attendance is not a gray area. It is spiritual treason.

In Camp B, the Society of Saint Pius X and classic canonical apologists fire back with the opposite warning: sever yourself from the public name of the visible Roman Pontiff, and you sever yourself from the visible structure of the Catholic Church itself. To refuse the Una cum altogether, they contend, risks sliding into a schismatic mindset, sectarian isolation that ends in dogmatic suicide. 

To this camp, non attendance is the real danger.

And then there is Camp C, the largest camp of all, though it has no website and no spokesman. These are the exhausted lay Catholics who wander between chapels, week after week, haunted by a single question: Does the priest's personal theology or factual error at the altar somehow contaminate the Host?

Or can an ordinary layman kneel in the pews, beg God for mercy, and receive the Bread of Life without adopting the clerical politics of the sanctuary?

Camp C has no manifesto. It has five children in the back of a station wagon and a dashboard clock that now reads 7:50 AM.

The father stares through the windshield. The road ahead is straight and empty.

To stay home feels like spiritual starvation: his family cut off from the Mass, from the Eucharist, from the sacramental life that is the oxygen of the Catholic soul.

To enter, according to at least one priest he trusts, is spiritual treason, a mortal sin that places him outside the communion of the faithful.

Starvation on the left. Treason on the right. And five minutes of county road in between.

How did we arrive here?

How did the most sublime prayer in Christendom, the Roman Canon, older than every cathedral in Europe, become an intellectual minefield that paralyzes a father in a parking lot?

Is attendance at an "Una Cum Mass" an act of apostasy? Or is the anti-Una Cum position a fundamental misunderstanding of Catholic sacramental theology, liturgical history, and canonical culpability, an error built on passion rather than principle, internet polemics rather than the Church's own jurisprudence?

To answer that question, we have to do something almost no one in this debate has been willing to do.

We have to set aside the blog posts. Lower the emotional temperature. And open the classic tomes of the Church herself: the scholastic dogmatics of St. Thomas Aquinas, the penal jurisprudence of the 1917 Codex Iuris Canonici, and the time tested moral casuistry of the Church's greatest doctors.

That is what this treatise does. From primary sources. Page by page. Canon by canon.

And the answer, when you see it laid bare, may change where you spend next Sunday morning.

Part II: The Status Quaestionis (From Polemics to Principles)

The fiery debates between sedevacantists who recognize that the laity may attend an una cum Mass out of spiritual necessity and strict "non una cum" sedevacantist factions do not turn on whether modernism is dangerous; every traditionalist agrees that Catholic doctrine is currently weathering a historic crisis.

The real clash turns entirely on three specific questions of dogmatic theology, clerical guilt, and moral cooperation:

Sacramental Mechanics and Liturgical History: What actually happens when a priest speaks the Una cum in the Roman Canon? Does naming an unorthodox prelate invalidate the Mass, or transform the Sacrifice of Calvary into a schismatic rite? The historical record is unambiguous: when emperors and kings fell into heresy, the Church struck their names from the liturgical diptychs immediately. The Te Igitur has never tolerated the commemoration of a notorious heretic. That means inserting such a name is an objective liturgical defect. But does that defect destroy the Sacrifice itself, or does the sacramental power of the priesthood, operating in persona Christi, remain untouched?

Clerical Guilt: What is the moral and legal standing of a traditional priest who recites the Una cum under good faith (bona fides) or factual error (error facti)? Is he automatically guilty of formal heresy, damned by the words on his lips, or is he laboring under an innocent material mistake that canon law has always distinguished from criminal intent?

Lay Assistance and Canon 2261, §2: Does an informed Catholic in the pew, who knows full well that the named prelate is objectively compromised, commit a mortal sin by attending? What constitutes a canonical "just cause" (iusta causa) permitting attendance, and how does classical casuistry allow the faithful to assist at the Holy Sacrifice without participating in the celebrant's error?

The treatise that follows systematically untangles each of these questions. It draws from primary canonical decrees, papal constitutions, and manualist theology, not blog posts, not polemical pamphlets, not YouTube influencers.

And it demonstrates three things the father in that parking lot desperately needs to know: why the Holy Sacrifice remains pure, how clerical error is judged under Catholic jurisprudence, and how an informed layman may lawfully conduct his conscience on Sunday morning.

Part III: The Dogmatic, Ecclesiological, and Liturgical Nature of the Una Cum

3.1 The Dual Character of the Te Igitur: Intercessory Petition and Profession of Communion

To understand the legal and dogmatic function of the Una cum, it is essential to first understand its liturgical nature. Grammatically and liturgically, the Una cum clause is fundamentally an intercessory prayer. It constitutes the opening petition of the Great Intercession within the Roman Canon of the Mass.

The Una cum occurs within the Te Igitur, the opening prayer of the Anaphora. The priest prays:

"In primis, quae tibi offerimus pro Ecclesia tua sancta catholica: quam pacificare, custodire, adunare et regere digneris toto orbe terrarum: una cum famulo tuo Papa nostro N., et Antistite nostro N., et omnibus orthodoxis, atque catholicae et apostolicae fidei cultoribus."

("Which in the first place we offer Thee for Thy holy Catholic Church: that Thou wouldst vouchsafe to pacify, guard, unite, and govern her throughout the whole world: together with Thy servant N. our Pope, and N. our Bishop, and all orthodox believers and maintainers of the Catholic and Apostolic Faith.")

As Rev. Adrian Fortescue explains in his historical analysis of the Roman Mass in The Catholic Encyclopedia, this prayer is an explicit petition of supplication and intercession. The priest asks Almighty God to grant specific spiritual and temporal blessings to the Church: peace (pacificare), protection (custodire), visible unity (adunare), and divine governance (regere). The Una cum phrase specifies that this intercession for the welfare of the Universal Church is offered alongside and on behalf of the visible earthly heads of the Church, the Sovereign Pontiff and the local diocesan Ordinary.

In the Summa Theologiae (II II, q. 83, a. 17; III, q. 83, a. 4), St. Thomas Aquinas analyzes the different types of prayer contained within the Holy Sacrifice of the Mass, building upon St. Paul's instruction to Timothy ("that supplications, prayers, intercessions, and thanksgivings be made for all men", 1 Tim. 2:1):

Supplications (Obsecrationes): The preparatory prayers calling upon God's mercy.

Prayers (Orationes): The consecration itself, wherein the mind is raised directly to God in the highest sense.

Intercessions (Postulationes or Intercessiones): The petitions that precede and follow the consecration, in which the priest implores divine graces for specific intentions and persons.

Thanksgivings (Gratiarum Actiones): The prayers of gratitude that conclude the sacred rite.

St. Thomas Aquinas places the petitions for the Universal Church, the Pope, the local Bishop, the civil rulers, and the living and deceased faithful squarely under the category of intercessions (intercessiones). In these prayers, the priest, acting in persona totius Ecclesiae (in the person of the whole Church), pleads the infinite merits of Christ's Eucharistic Sacrifice before God the Father on behalf of the Church's earthly hierarchy and faithful.

While the Una cum is grammatically and interiorly an intercessory petition, it simultaneously carries a canonically binding function as a public manifestation of visible communion (communio):

An Intercession for the Hierarchy: The Church intercedes for her chief pastors so that God may grant them the grace, wisdom, fortitude, and orthodoxy necessary to govern the flock of Christ effectively.

A Test of Orthodox Communion: Because public intercession at the altar is offered pro Ecclesia (for the Church) and una cum (together with) her legitimate shepherds, naming a prelate in the Te Igitur publicly testifies that the priest and congregation are in active, visible communion with that prelate.

As Rev. Eric MacKenzie observes in The Delict of Heresy, the Church's liturgical law forbids offering the official, public intercessions of the Canon for notorious heretics or excommunicates as if they were valid pastors of the Church, because public liturgical intercession implies active, mutual membership in the same Mystical Body.

To summarize, the Una cum is an intercessory petition asking God to preserve, govern, and unify His Church together with her earthly chief pastors. At the same time, because it names the Pope and Bishop as the living anchors of that Church, it doubles as the official professing of visible communion between the altar and the Catholic hierarchy.

3.2 Sacerdotal Agency: In Persona Christi versus In Persona Totius Ecclesiae

To analyze the mechanics of the Una cum, one must employ the classical scholastic distinction regarding the dual operational mode of the ordained priest at the altar.

St. Thomas Aquinas establishes in the Summa Theologiae (III, q. 82, a. 5; q. 82, a. 7, ad 3; q. 83, a. 1, corp. et ad 3) that in the actual consecration of the Eucharistic species, the priest operates exclusively in persona Christi. By virtue of the character imprinted upon his soul at ordination, the priest is an instrumental cause through whom Christ Himself acts as the principal minister. Consequently, the consecration of the bread and wine depends strictly upon valid matter, proper form, a validly ordained priest, and the sacramental intention to do what the Church does (intentio faciendi quod facit Ecclesia).

Conversely, in reciting the surrounding prayers, supplications, and intercessions of the liturgy—most notably the prayers of the Canon before and after the consecration—the celebrant acts in persona totius Ecclesiae ("in the person of the whole Church"). In these prayers, the priest acts as the Church's public legate, offering intercessory petitions in her name.

As St. Thomas demonstrates in Summa Theologiae, III, q. 82, a. 5, the personal holiness, orthodoxy, or ecclesiastical standing of the minister does not destroy the validity of the sacrifice:

"The priest, in reciting the prayers of the Mass, speaks in the person of the Church, in whose unity he remains; but in consecrating the sacrament he speaks in the person of Christ, Whose place he holds by the power of his orders. Consequently, if a priest severed from the unity of the Church celebrates Mass... because he consecrates in the person of Christ, he performs a true sacrament; but because he offers prayers in the person of the Church, from whose unity he is separated, his prayers have no efficacy."

(St. Thomas Aquinas, Summa Theologiae, III, q. 82, a. 5, corp.; see also q. 82, a. 7, corp.).

Sacramental validity is wholly insulated from the celebrant's personal theology or liturgical intercessions. The bread and wine become the Body, Blood, Soul, and Divinity of Jesus Christ ex opere operato the moment the words of consecration are pronounced, regardless of the names whispered minutes earlier in the Te Igitur.

                 



3.3 The Meaning of Una Cum in Liturgical Hermeneutics

The opening intercession of the Roman Canon reads:

"In primis, quæ tibi offérimus pro Ecclésia tua sancta cathólica: quam pacificáre, custodíre, adunáre, et régere dignéris toto orbe terrárum: una cum fámulo tuo Papa nostro N., et Antístite nostro N., et ómnibus orthodóxis, atquæ cathólicæ et apostólicæ fídei cultóribus."

(Missale Romanum, Canon Missae).

Grammatically and liturgically, the phrase una cum famulo tuo Papa nostro N. does not signify that the sacrifice is offered by the Pope or that its intrinsic efficacy depends upon the doctrinal purity of the named pontiff or bishop. Rather, as liturgical historians and canonists observe, the clause is an intercessory qualification: the sacrifice is offered on behalf of (pro) the whole Church, together with (una cum) its visible hierarchical head, the local ordinary, and all orthodox confessors of the Catholic faith (The Catholic Encyclopedia, Vol. 3, entry "Canon of the Mass," sub-entry "Te Igitur," pp. 256–257).

If an erring or illegitimate name is inserted, the Eucharistic consecration remains completely valid because sacramental power flows from Holy Orders and the sacramental form, not from the accuracy of the intercessory list (Summa Theologiae, III, q. 82, a. 5, ad 1; q. 83, a. 1).

3.4 Liturgical Diptychs, Temporal Rulers, and the Exclusion of Heretics from the Roman Canon

To understand the legal and dogmatic function of the Una cum, it is essential to examine the origin of the clause in the ancient liturgical diptychs and the Church’s unbending discipline regarding who may be named at the altar.

Historically, the practice of naming the Pope, local ordinary, and Christian sovereigns (et Rege nostro) in the Te Igitur developed directly from the ancient diptychs—the two-leaved tablets read publicly during the Eucharistic liturgy containing the roll call of the faithful living and dead (The Catholic Encyclopedia, Vol. 5, entry "Diptych," pp. 22–24; Vol. 3, entry "Canon of the Mass," sub-entry "Te Igitur," p. 257).

A critical historical and dogmatic fact governs this practice: If an emperor, king, or prelate fell into notorious heresy, public schism, or was formally excommunicated, he was strictly and immediately excluded from the diptychs and barred from commemoration in the Canon of the Mass.

Catholic liturgical law and dogmatic jurisprudence have always maintained that public liturgical commemoration at the altar requires visible communion in the true Faith:

The Absolute Exclusion of Non-Catholics from the Diptychs:

The ancient diptychs admitted exclusively those who lived and died in full, visible communion with the Catholic Church. As liturgical historians document in The Catholic Encyclopedia, the names of heretics, schismatics, and excommunicates were rigorously erased. No earthly status could preserve a ruler from this penalty: "the highest dignity, episcopal or imperial, would not avail to save the offender from its infliction" (The Catholic Encyclopedia, Vol. 5, entry "Diptych," p. 23).

Historical Precedents of Striking Heretical Emperors from the Canon:

When Byzantine rulers embraced heterodoxy, the Holy See and the Roman clergy responded by striking their names from the public prayers of the altar:

The Monothelite Crisis (712 AD): When the Byzantine Emperor Philippicus Bardanes embraced the Monothelite heresy and burned the acts of the Third Council of Constantinople (Sixth Ecumenical Council), Pope Constantine and the Church of Rome rejected his imperial authority in sacred affairs. The Romans refused to place his image on coins, refused to erect his statue in churches, and explicitly refused to recite his name in the Canon of the Mass (The Catholic Encyclopedia, Vol. 4, entry "Pope Constantine," p. 294; Vol. 12, entry "Philippicus," p. 12).

The Iconoclast Persecution: When Emperor Leo III the Isaurian decreed the destruction of sacred images and threatened the Roman Pontiff, Pope St. Gregory II and Pope St. Gregory III formally condemned the heresy and expunged the imperial name from liturgical honor.

The English Reformation: When King Henry VIII and later Queen Elizabeth I separated England from the Holy See and established state heresy, the Popes excommunicated them, ensuring that no Catholic priest could lawfully include et Rege nostro or et Regina nostra for a separated, non-Catholic sovereign.

The Syntactic and Doctrinal Intrinsic Contradiction:

The Te Igitur asks God to guard and govern His Church:

 ...una cum [...] et omnibus orthodoxis, atque catholicae et apostolicae fidei cultoribus. 

Because the prayer characterizes those in communion as "orthodox believers and maintainers of the Catholic and Apostolic Faith," the deliberate liturgical commemoration of an acknowledged, notorious heretic involves an intrinsic objective falsehood.

Public Liturgical Oblation (In Persona Ecclesiae) vs. Private Intercession:

St. Thomas Aquinas clarifies in the Summa Theologiae (III, q. 82, a. 5; q. 83, a. 4) that prayers offered in persona Ecclesiae belong strictly to the Mystical Body. While a priest may offer private suffrages or pray privately for the conversion of an excommunicate, the 1917 Codex Iuris Canonici codifies this classical doctrine in Canon 2262, §1: excommunicated persons are strictly excluded from the public liturgical prayers (publicae orationes) of the Church (cf. Eric F. MacKenzie, The Delict of Heresy, pp. 34–38).

Royal Indults Applied Strictly to Catholic Princes:

When temporal monarchs were commemorated in the Canon—such as before the 1570 reform of Pope St. Pius V, or under subsequent apostolic indults granted to the Spanish Empire and the Austro-Hungarian Habsburg monarchy—Rev. Adrian Fortescue observes that these concessions applied strictly to Catholic princes who governed in formal submission to the Holy See (The Catholic Encyclopedia, Vol. 3, p. 257).

The Theological Bearing on the Present Inquiry:

Liturgical history definitively demonstrates that the Church’s objective law excludes notorious heretics from the Una cum. Therefore, inserting the name of an objective heretic is an objective liturgical defect.

However, this objective defect does not solve the subjective question: 

What is the canonical status of a priest who recites the name under invincible ignorance or factual error (error facti)? As established below in Part IV, an objective liturgical anomaly does not constitute a canonical delict without formal pertinacity, nor does it destroy the validity of the sacrifice consecrated in persona Christi.

Part IV: Canonical Jurisprudence and Delictual Imputability: Formal versus Material Heresy

4.1 The Delict of Heresy and Canonical Imputability

Canon law and Catholic moral theology make a strict distinction between the objective reality of an error (error materialis) and the subjective criminality of a delict (delictum formale).

Under the 1917 Codex Iuris Canonici, Canon 1325, §2 defines the canonical categories:

"Any person who, after receiving baptism, while retaining the name of Christian, obstinately denies or doubts any of the truths which must be believed by divine and Catholic faith, is a heretic; if he falls away entirely from the Christian faith, he is an apostate; if he rejects the authority of the Supreme Pontiff or refuses communion with the members of the Church subject to him, he is a schismatic."

(CIC 1917, Canon 1325, §2; cf. Stanislaus Woywod, The New Canon Law, p. 270).

For any error to become a canonical delict (delictum) carrying ecclesiastical penalties and loss of office, moral jurisprudence demands the concurrence of two distinct elements:

The Material Element (factum externum): An external proposition or action contrary to a dogma of the Catholic faith.

The Formal Element (pertinacia or malicious intent): A deliberate, obstinate resistance to the known teaching authority of the Church.

Rev. Eric F. MacKenzie, in his definitive canonical study The Delict of Heresy in Its Commission, Penalization, Absolution (Catholic University of America Canon Law Studies, No. 77 [1932], Chapter II, "The Material Element of the Delict," pp. 22–29; Chapter III, "The Formal Element: Pertinacity," pp. 32–41), demonstrates that pertinacity does not denote temporal duration, stubbornness of temperament, or vehement passion, but rather the conscious, willful rejection of a truth known to be proposed by the Church as divinely revealed:

"The absence of pertinacity excuses a person from the delict of heresy. Mere objective opposition to Catholic doctrine does not constitute a canonical crime without internal obstinacy against the Church's magisterium."

(MacKenzie, The Delict of Heresy, Chapter III, pp. 34–36).

This principle aligns directly with Canons 2199 and 2200 of the 1917 Code. While Canon 2200, §2 dictates that when an external violation of the law occurs, intentional malice (dolus) is presumed in the external forum until the contrary is proved, this presumption is strictly iuris tantum (rebuttable by evidence). It yields completely to proven ignorance, inadvertence, or error:

"Ignorance of the law or of the penalty excuses from all penalty, provided the ignorance was not affected or crass... Likewise, an erroneous judgment or inadvertence excuses."

(CIC 1917, Canon 2202, §1; cf. MacKenzie, The Delict of Heresy, pp. 36–38).

4.2 The Celebrant Operating under Error Facti (Good Faith / Bona Fides)

When applied to the priest standing at the altar, the distinction between formal malice and material participation is definitive:

Theological Category

  • Formal Malice (Dolus / Pertinacia)
  • Material Error (Error Facti / Bona Fides)

Interior Motive

  • Willful adhesion to heresy; deliberate intent to communicate with an acknowledged false teacher.
  • Sincere intent to offer the Holy Mass in union with the legitimate Catholic hierarchy.

State of Mind

  • Clear knowledge of heresy paired with obstinate rejection of the Magisterium.
  • Invincible ignorance, erroneous factual judgment, or misapprehension of the prelate's true canonical standing.

Canonical Guilt

  • Incurs ipso facto excommunication (Canon 2314, §1) and canonical infamy.
  • Free from canonical censures; acts under a blameless material mistake (Canon 2202, §1).

Efficacy of Intention

  • Directs the public prayer to an acknowledged separated sect.
  • Substantially directs the offering to the true Papacy and the Mystical Body of Christ.

Dominic M. Prümmer, O.P., in his Handbook of Moral Theology (Treatise I, "Vices Opposed to Faith," nn. 500–503), confirms that:

"Material heresy is an error in faith committed through inculpable ignorance or good faith... Material heretics commit no sin against faith, because their error is involuntary."

(Prümmer, Handbook of Moral Theology, n. 501; see also Henry Davis, S.J., Moral and Pastoral Theology, Vol. I, "Theological Virtues: Faith," Section 4, pp. 280–282).

If a priest pronounces the name of a superior who is an objective heretic—sincerely believing that superior to be a legitimate Catholic bishop or Pope—his act is an involuntary, material error (error facti). His primary, habitual intention is directed toward the legitimate Catholic hierarchy and the Catholic Church.

As Frs. Charles J. Callan, O.P., and John A. McHugh, O.P., explain in Moral Theology: A Complete Course Based on St. Thomas Aquinas (Vol. I, "Sins Against Faith," nn. 825–830; "The Nature of Imputability," nn. 1502–1508), an involuntary defect in execution does not alter the fundamental moral identity of a virtuous act when the error resides in accidental factual circumstances rather than the formal object of the will.

Part V: Sacramental Validity, Licit Administration, and the Norms of Communicatio in Sacris

5.1 The Principle of Ad Evitanda Scandala and Canon 2261

To resolve whether the faithful may lawfully approach an erring priest, Catholic theology looks to the historic Constitution Ad Evitanda Scandala, promulgated by Pope Martin V at the Council of Constance (1418).

Prior to this decree, the faithful were strictly bound under pain of sin to abstain from communion and liturgical contact with anyone known to be excommunicated. Pope Martin V established a radical relaxation of positive ecclesiastical discipline to protect consciences:

To avoid scandal and dispel anxieties, no one is bound to abstain from ecclesiastical communion or sacramental reception with any minister, nor to avoid them, unless that minister has been explicitly and personally condemned by judicial sentence, or is publicly denounced as an excommunicatus vitandus.

(Pope Martin V, Const. Ad Evitanda Scandala, 1418; see Denzinger, Enchiridion Symbolorum, n. 588).

This legislation was codified directly in the 1917 Codex Iuris Canonici, Canon 2261, §§1–3:

Canon 2261, §1: An excommunicated person is prohibited from licitly celebrating the sacraments.

Canon 2261, §2: "The faithful, however, subject to the provisions of §3, may for any just cause request the sacraments and sacramentals from an excommunicated minister, especially if other ministers are lacking; and then the excommunicated person who is requested may administer them, and is under no obligation to inquire into the reason for the request."

(CIC 1917, Canon 2261, §2; cf. Stanislaus Woywod, The New Canon Law, pp. 450–451).

Canon 2261, §3: This concession applies solely to excommunicati tolerati; from an excommunicatus vitandus or a minister against whom a declaratory or condemnatory sentence has been issued, the sacraments may only be requested in danger of death (in periculo mortis).

Under Canon 2258, §2, a person is an excommunicatus vitandus only if two conditions are met simultaneously:

  • The person has been publicly excommunicated by the Holy See by name.
  • The decree explicitly designates the person as vitandus ("to be shunned").

Because a traditional Catholic priest operating in good faith (bona fide) has neither been condemned by judicial decree nor publicly designated a vitandus, he remains fundamentally toleratus. Under Canon 2261, §2, the faithful are explicitly permitted by canon law to approach such a priest for sacramental reception and holy Mass for any just cause (ex qualibet iusta causa).

5.2 Exhaustive Canonical Exegesis: What Constitutes a "Just Cause" (Iusta Causa) under Canon 2261, §2?

A central point of contention among traditionalist critics of the una cum Mass is the assertion that the faithful may only approach an irregular or materially compromised minister in instances of grave necessity or imminent danger of death.

This objection is directly refuted by the precise legal phrasing of Canon 2261, §2 and its unanimous interpretation by Catholic canonists.

The text of the canon explicitly uses the expansive phrase:

{‘ex qualibet iusta causa”} (for any just cause whatsoever)

It does not say ex gravi causa (for a grave cause), nor does it require in periculo mortis (in danger of death)—which is reserved strictly for §3 regarding vitandi.

The standard commentators on the 1917 Code define iusta causa with consistent pastoral breadth:

Rev. Charles Augustine, O.S.B. (A Commentary on the New Code of Canon Law, Vol. VIII, "Penal Law," commentary on Can. 2261, pp. 176–178):

Augustine points out that the legislator deliberately used the word qualibet ("any") to remove scruples and ensure the spiritual liberty of the faithful:"The faithful may, for any just reason, ask for the sacraments or sacramentals from a toleratus... What is a just cause? A just cause is any reasonable motive, such as devotion, spiritual advantage, a desire to hear Mass on Sundays or holy days, or the fact that no other priest is readily available without serious inconvenience. It does not require extreme or even grave necessity. The law says 'any just cause,' which must be interpreted broadly in favor of the salvation of souls."

(Augustine, A Commentary on the New Code of Canon Law, Vol. VIII, pp. 176–177).

Rev. Stanislaus Woywod, O.F.M. (The New Canon Law: A Commentary and Summary, commentary on Canon 2261, pp. 450–451; see also A Practical Commentary on the Code of Canon Law, Vol. II, n. 2115):

Woywod confirms that the faithful are not obliged to prove a critical emergency: "Any just cause suffices, for instance, genuine devotion, the desire to receive Holy Communion more frequently, the convenience of the time or place, or because it would be troublesome to find another priest. Furthermore, the faithful are under no obligation to explain their motive to the minister, nor is the minister permitted to question them regarding the legitimacy of their request."

(Woywod, The New Canon Law, p. 450).

Very Rev. Dominic M. Prümmer, O.P. (Handbook of Moral Theology, "Tractatus de Censuris: De Excommunicatione," n. 915):

Prümmer notes that because the Church’s positive penal law was reformed by Martin V specifically ad consulendum conscientiis (to care for consciences) and ad evitanda scandala (to avoid scandal):"A just cause is present whenever the petitioner acts out of an honest motive of religion, such as the sanctification of Sunday, avoiding spiritual languor, obtaining peace of mind, or avoiding familial dissension."

(Prümmer, Handbook of Moral Theology, n. 915).

Rev. Henry Davis, S.J. (Moral and Pastoral Theology, Vol. IV, "Treatise on Censures: Excommunication," pp. 111–114):

Davis explains that the condition praesertim si desint alii ministri ("especially if other ministers are lacking") is demonstrative, not taxative:"The clause 'especially if other ministers are lacking' shows what would normally be the most common just cause, but it is not an absolute condition. Any spiritual advantage—such as hearing Mass, receiving absolution, or participating in the liturgical life of the Church—constitutes a legally sufficient cause."

(Davis, Moral and Pastoral Theology, Vol. IV, p. 112).

Consequently, an informed Catholic layman who attends an una cum Mass celebrated by a toleratus in order to satisfy the Sunday obligation, receive the Eucharist, or foster personal piety possesses a fully verified, canonically recognized iusta causa.

5.3 Distinctions in Communicatio in Sacris (Canon 1258)

Canon law strictly regulates participation in sacred worship:

Canon 1258, §1: "It is unlawful for the faithful to assist actively in any way, or take part in the sacred rites of non-Catholics."

Canon 1258, §2: "Passive or merely material presence may be tolerated for a grave reason, on account of civil duty or honor... provided there is no danger of perversion or scandal."

(CIC 1917, Canon 1258; cf. Augustine, Commentary on Canon Law, Vol. VI, pp. 195–198).

The fundamental distinction lies in the nature of the rite itself:

Active participation in a non-Catholic rite (in sacris acatholicorum): Intrinsically illicit when the rite is inherently sectarian, false, or severed from Catholic worship.

Assisting at the Mass of a Catholic priest with material defects: This does not constitute an acatholic rite. The Mass remains the unadulterated Roman Rite offered by a validly ordained Catholic priest using an authentic missal. The priest is not offering a schismatic liturgy; he is executing the Church's liturgical rite while laboring under a subjective, material mistake regarding the person of the prelate.

Part VI: The Casuistry of Lay Assistance at the Mass of an Erring Celebrant

6.1 The Functional Severability of the Priest’s Prayer from the Layman’s Assistance

A foundational principle of Catholic liturgical theology is that the priest does not act as an agent of the congregation, but as an agent of Christ and the Church.

In the traditional Roman Rite, the Canon is recited in a low voice (vox secreta), reserved entirely to the celebrant. The layman sitting in the nave neither recites, pronounces, nor vocally ratifies the Una cum clause.

As Henry Davis, S.J., points out in Moral and Pastoral Theology (Vol. I, "Cooperation in Evil," pp. 338–344; Vol. II, "The Mass," pp. 30–35), an individual's presence at an action where a material error occurs does not impute that error to the observer, provided:

  • The action itself is intrinsically good (the Holy Sacrifice of the Mass).
  • The observer's assistance is directed toward the intrinsic good of the act (finis operis).
  • The observer formally disassociates their internal will from the accidental defect of the minister (finis operantis).

Consequently, an informed Catholic sitting in the pews does not adopt the priest's material error. The layman assists in persona populi to render divine adoration, offer spiritual sacrifice, fulfill a grave precept, and receive sacramental grace.



6.2 The Four Moral Criteria for Lawful Attendance

According to the classical moral casuistry articulated by St. Alphonsus Liguori (Theologia Moralis, Lib. II, Tract. I, Cap. 3, Dub. V, nn. 53–55), Heribert Jone (Moral Theology, nn. 120–124), and Callan & McHugh (Moral Theology, Vol. I, nn. 850–865), a knowledgeable layman may lawfully attend the Mass of a priest who erroneously inserts a heterodox name into the Una cum, provided four specific conditions are met:

1. Legitimate Spiritual Reason (Causa Rationabilis / Iusta Causa)

Attendance cannot be born of frivolity, curiosity, or indifference to doctrine. The faithful must be motivated by a proportionate spiritual good:

  • Fulfilling the divine and ecclesiastical precept of Sunday Mass attendance (Canon 1248).
  • Procuring sacramental absolution or Holy Communion for the nourishment of the soul.
  • Avoiding spiritual starvation, despair, or the grave burden of isolation when no entirely immune priest is accessible.

2. Complete Interior Non-Assent (Non-Cooperatio Formalis)

The layman must internally dissent from the error. When the priest pronounces the name of the compromised prelate during the Te Igitur, the congregant explicitly directs their interior intention away from that individual, uniting their prayer instead to Jesus Christ—the Supreme Pontiff—and to all true, orthodox bishops throughout the world. This preserves the layman from formal cooperation in error (Callan & McHugh, Moral Theology, Vol. I, nn. 1506–1510).

3. Exclusion of Active Scandal (Secluso Scandalo)

The presence of the layman must not cause spiritual ruin to others by leading them to believe that:

  • The layman endorses the heresy or heterodox actions of the prelate named.
  • Theological errors regarding the Papacy or the Magisterium are matters of indifference.

If the layman holds a public role or their presence would be misconstrued, they are morally obligated to discreetly make their theological position known to interested parties or choose non-attendance if active scandal cannot be avoided (St. Alphonsus, Theologia Moralis, Lib. II, Tract. III, Cap. 2, "De Scandalo," nn. 45–50).

4. Immunity from Perversion (Secluso Periculo Perversionis)

The congregant must possess moral certainty that ongoing attendance will not gradually erode their own orthodoxy or weaken their resolve against error. If the priest delivers sermons promoting explicit heresy or attempts to impose compromised doctrines upon the faithful, the danger of spiritual perversion becomes proximate, rendering attendance gravely illicit (Prümmer, Handbook of Moral Theology, n. 520; Jone, Moral Theology, n. 124).

Part VII: Synthetic Resolution and Casuistical Flowchart

7.1 Case Resolution: The Informed Layman and the Mistaken Celebrant

When the elements of the inquiry are synthesized according to the classical theological manuals, the resolution of the case proceeds as follows:

              



7.2 The Distinction between Liturgical Formula and Dogmatic Profession

A critical flaw in contemporary non-una cum polemics is treating the Una cum clause as an absolute dogmatic definition or a sacramental sign that confers its content automatically (ex opere operato).

As demonstrated by liturgical history, the Canon developed as an intercessory litany. It petitions God to govern the Church together with the visible servants who occupy ecclesiastical offices (and historically, alongside Christian monarchs). When a minister errs regarding the legitimate occupant of an office, God does not validate the error; rather, the Church's habitual intention (intentio Ecclesiae) supplies for the accidental flaw, accepting the priest's oblation on behalf of the real, unblemished Mystical Body of Christ.

Part VIII: Conclusion

To synthesize the dogmatic, canonical, and moral evidence:

The Nature of the Mass: The Eucharistic Sacrifice celebrated by a valid Catholic priest using an authentic Catholic rite remains a valid, holy oblation capable of conferring grace. The personal errors, administrative misjudgments, or material mistakes of the priest do not destroy its sacramental efficacy (Summa Theologiae, III, q. 82, a. 5).

The Intercessory Nature of the Prayer: St. Thomas Aquinas (Summa Theologiae II II, q. 83, a. 17) explicitly categorizes the petitions of the Te Igitur as intercessions (postulationes). The historical inclusion of Catholic temporal rulers (et Rege nostro) further confirms that the clause is an intercessory prayer for the Church, not an operative sacramental formula. Simultaneously, the Church's strict historical exclusion of heretical or excommunicated rulers proves that naming an objective heretic is a genuine liturgical defect. However, because this prayer is intercessory (offered in persona Ecclesiae) rather than sacramental (in persona Christi), an accidental error in the names recited does not alter or destroy the valid sacrificial nature of the Mass.

The Status of the Celebrant: A priest who erroneously inserts the name of an objective heretic into the Una cum while acting in good faith (bona fide) and lacking pertinacity (pertinacia) is guilty of material error (error materialis), not formal heresy or schism (MacKenzie, The Delict of Heresy, pp. 32–36). He remains a minister toleratus under Canon 2261, §2.

The "Just Cause" of the Faithful: Canon 2261, §2 explicitly permits the faithful to seek the sacraments from a toleratus for any just cause (ex qualibet iusta causa). This does not require extreme emergency, but encompasses fulfilling the Sunday precept, receiving the Holy Eucharist, or nourishing spiritual life (Augustine, Vol. VIII, pp. 176–178; Woywod, p. 450).

The Position of the Faithful: An informed Catholic who assists at such a Mass does not adopt the celebrant's mistake. Because the Una cum is spoken by the priest alone in persona Ecclesiae, the layman's presence in persona populi remains entirely licit, provided the layman maintains interior dissent from the named prelate, possesses a proportionate spiritual reason, avoids active scandal, and guards against doctrinal compromise.
