Catholic Church Teaching on Heresy and the Pope Can. 1364— § 1. An apostate from the faith, a heretic or a schismatic incurs a latae sententiae [automatic] excommunication.
“Cum ex Apostolatus Officio” -Apostolic Constitution of Pope Paul IV, 1559In addition, [by this Our Constitution, which is to remain valid in perpetuity We enact, determine, decree and define] that if ever at any time it shall appear that any Bishop, even if he be acting as an Archbishop, Patriarch or Primate; or any Cardinal of the aforesaid Roman Church, or, as has already been mentioned, any legate, or even the Roman Pontiff, prior to his promotion or his elevation as Cardinal or Roman Pontiff, has deviated from the Catholic Faith or fallen into some heresy:
(i) the promotion or elevation, even if it shall have been uncontested and by the unanimous assent of all the Cardinals, shall be null, void and worthless…
Pope Julius II, Council of Lateran V. 1513
It shall be lawful for each and all of the cardinals,…as well as for all the clergy and the Roman people,… to withdraw without penalty and at any time from obedience and loyalty to the person so elected even if he has been enthroned (while they themselves, notwithstanding this, remain fully committed to the faith of the Roman church and to obedience towards a future Roman pontiff entering office in accordance with the canons) and to avoid him as a magician, a heathen, a publican and a heresiarch.”
St. Francis de Sales, “The Catholic Controversy”
“Now when [the Pope] 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.”
St. Robert Bellarmine, “On the Roman Pontiff”
“…a pope who is a manifest heretic by that fact ceases to be pope and head, just as he by that fact ceases to be a Christian and a member of the body of the Church; wherefore he can be judged and punished by the Church. This is the judgment of all the early fathers, who teach that manifest heretics immediately lose all jurisdiction.”
St. Alphonsus de Liguori, “The Truths of the Faith”
“If God permitted a pope to be notoriously heretical and contumacious, he would then cease to be pope, and the Apostolic Chair would be vacant.”
A Catholic Dictionary, 1951. Deposition
“An heretical pope necessarily ceases to be head of the Church, for by his heresy he is no longer a member thereof: in the event of his still claiming the Roman see a general council, improperly so-called because without the pope, could remove him. But this is not deposition, since by his own act he is no longer pope.”
Catholic Encyclopedia, 1913. [Vol. IV p.435] Councils
“The councils of Constance and Basle, and Gallican theologians, hold that a council may depose a pope…(2) /ob fidem/ (on account of his faith or rather want of faith, i.e. heresy). In point of fact however, heresy is the only legitimate ground. For a heretical pope has ceased to be a member of the Church, and cannot, therefore, be its head.”
Titus, Chapter 3 [Douay Rheims uncorrupted BIBLE]-
10 A man that is a heretic, after the first and second admonition, avoid:
11 Knowing that he that is such a one, is subverted, and sinneth, being condemned by his own judgment.
Rev. E. Sylvester Berry ‘The Apocalypse of St John’, 1921, p 138
Father Berry also explained: “There will be a complete organization ─ a church of Satan set up in opposition to the Church of Christ. Satan will assume the part of God the Father; Antichrist will be honoured as Saviour, and his prophet will usurp the role of Pope.”
Can. 1364— § 1. An apostate from the faith, a heretic or a schismatic incurs
a latae sententiae [automatic] excommunication.

“It is not to be excluded that I will enter history as the one who split the Catholic Church.”
