A heretic, according to Canon 1325.2 is “one who, after the reception of baptism pertinaciously denies or doubts any of the truths to believed by divine and Catholic faith.” The teaching must be an article “of divine and Catholic faith” that the Church has authentically proposed as such.
A prior ex cathedra or conciliar definition is not required. “The explicit teaching of the universal ordinary Magisterium suffices for a truth to be authentically proposed for adherence by the faithful.” (See Michel, DTC 6:2215)
The heretic may deny the doctrine “in explicit or equivalent terms,” (See R. Schultes, De Ecclesia Catholica: Praelectiones Apologeticae (Paris: Lethielleux 1931), 638. “verbis explicitis vel aequivalentibus.”) through either a contradictory or a contrary proposition.
(B) Heretical Teachings
- Justification: The October 31, 1999 Joint Declaration on Justification , approved by Ratzinger and John Paul II. This overthrows the solemn dogmatic definitions of the Council of Trent concerning justification.
- The Church: The Declaration on Communion, the Ecumenical Directory and the Declaration Dominus Jesus, written by Ratzinger and approved by John Paul II.
These documents promote the “Subsistent Superchurch” heresy, as Fr. Cekada calls it, which, among other things, denies an article of the Creed (“I believe in one Church”), as well as the proposition “outside the Church there is no salvation.”
- Actions such as JP II kissing the blasphemous Koran. Canonists and theologians teach that external heresy consists in dictis vel factis — not only in words, but also in “signs, deeds, and the omission of deeds.” (Merkelbach, Summa Theologiae Moralis, 1:746.) Vatican II apologist Jimmy Akin (http://www.jimmyakin.org/) has tried to defend this kissing of the Koran because JPII may have wanted to show respect for "elements of truth" that the Islamic unholy book contains. Using the same logic, one could excuse kissing the Satanic Bible because it teaches "elements of truth" as well!
- Declaring "valid" a "mass" with no words of Consecration!!!
The list could go on and on, but one thing is for certain: it's much easier to point to the few instances of NON-HERETICAL statements and actions of the post-conciliar "popes" than the plethora of heresy the Unholy Fathers of Modernist Rome regularly pour forth leading to the damnation of souls.
