- Doctor of the Church St. Francis de Sales totally confirmed beyond any doubt the possibility of a heretical pope and what must be done by the Church in such a situation:
"[T]he Pope... WHEN he is EXPLICITLY a heretic, he falls ipso facto from his dignity and out of the Church, and the Church MUST either deprive him, or, as some say, declare him deprived, of his Apostolic See."
(The Catholic Controversy, by St. Francis de Sales, Pages 305-306)
Saint Robert Bellarmine, also, said "the Pope heretic is not deposed ipso facto, but must be declared deposed by the Church."
- LifeSiteNews, "Confusion explodes as Pope Francis throws magisterial weight behind communion for adulterers," December 4, 2017:
The AAS guidelines explicitly allows "sexually active adulterous couples facing 'complex circumstances' to 'access the sacraments of Reconciliation and the Eucharist.'"
- On February 2018, in Rorate Caeli, Catholic theologian Dr. John Lamont:
"The AAS statement... establishes that Pope Francis in Amoris Laetitia has affirmed propositions that are heretical in the strict sense."
- On December 2, 2017, Bishop Rene Gracida:
"Francis' heterodoxy is now official. He has published his letter to the Argentina bishops in Acta Apostlica Series making those letters magisterial documents."
