6. In 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;
(ii) it shall not be possible for it to acquire validity (nor for it to be said that it has thus acquired validity) through the acceptance of the office, of consecration, of subsequent authority, nor through possession of administration, nor through the putative enthronement of a Roman Pontiff, or Veneration, or obedience accorded to such by all, nor through the lapse of any period of time in the foregoing situation;
(iii) it shall not be held as partially legitimate in any way;
(iv) to any so promoted to be Bishops, or Archbishops, or Patriarchs, or Primates or elevated as Cardinals, or as Roman Pontiff, no authority shall have been granted, nor shall it be considered to have been so granted either in the spiritual or the temporal domain;
(v) each and all of their words, deeds, actions and enactments, howsoever made, and anything whatsoever to which these may give rise, shall be without force and shall grant no stability whatsoever nor any right to anyone;
(vi) those thus promoted or elevated shall be deprived automatically, and without need for any further declaration, of all dignity, position, honour, title, authority, office and power.

St Robert Bellarmine, Doctor of the Church, "De Romano Pontifice", ("On the Roman Pontiff"), liber II, caput 30:
"For, in the first place, it is proven with arguments from authority and from reason that the manifest heretic is "ipso facto" deposed. The argument from authority is based on St. Paul (Titus, c. 3), who orders that the heretic be avoided after two warnings, that is, after showing himself to be manifestly obstinate - which means before any excommunication or judicial sentence. And this is what St. Jerome writes, adding that the other sinners are excluded from the Church by sentence of excommunication, but the heretics exile themselves and separate themselves by their own act from the body of Christ. Now, a Pope who remains Pope cannot be avoided, for how could we be required to avoid our own head? How can we separate ourselves from a member united to us?
"This principle is most certain. The non-Christian cannot in any way be Pope, as Cajetan himself admits (ib. c. 26). The reason for this is that he cannot be head of what he is not a member; now he who is not a Christian is not a member of the Church, and a manifest heretic is not a Christian, as is clearly taught by St. Cyprian (lib. 4, epist. 2), St. Athanasius (Scr. 2 cont. Arian.), St. Augustine (lib. de great. Christ. cap. 20), St. Jerome (contra Lucifer.) and others; therefore the manifest heretic cannot be Pope.
Est ergo quinta opinio vera, papam haereticum manifestum per se desinere esse papam et caput, sicut per se desinit esse christianus et membrum corporis Ecclesiae; quare ab, Ecclesia posse eum judicari et puniri. Haec est sententia omnium veterum Patrum, qui docent, haereticos manifestos mox amittere omnem jurisdictionem.
"Therefore, the true opinion is the fifth, according to which the Pope who is manifestly a heretic ceases by himself to be Pope and head, in the same way as he ceases to be a Christian and a member of the body of the Church; and for this reason he can be judged and punished by the Church. This is the opinion of all the ancient Fathers, who teach that manifest heretics immediately lose all jurisdiction,
Fundamentum hujus sententiae est. quoniam haereticus manifestos nullo modo est membrum Ecclesiae, idest, neque animo neque corpore, sive neque unione interna, neque externa.
"The foundation of this argument is that the manifest heretic is not in any way a member of the Church, that is, neither spiritually nor corporally, which signifies that he is not such by internal union nor by external union.
I agree. But due to our sins and rejection and rebellion against God’s holy laws, especially Humanae Vitae and humility before the Eucharist, explained by the Catholic Church we deserve what is happening, as St. Francis fortold:
“Prophecy of Saint Francis” (http://spir-food.blogspot.it/2013/11/prophecy-st-francis.html):
2. The power of the demons will be greater than usual, the immaculate purity of our religious community and of others, will withered to the point that very few Christians will want to obey the true Sovereign Pontiff and the Roman Church with a sincere heart and perfect charity. At the decisive moment of this crisis, a personage not canonically elected, raised to the Pontificate, will endeavor to administer shrewdly to many the mortal poison of his error.
7. Some preachers will keep silent about the truth and, denying the truth, they will trample upon the truth. The sanctity of life will be held in derision by those who only profess it outwardly, and for this reason Our Lord Jesus Christ will send them not a worthy Pastor, but a destroyer.”
“When God wants to chastise humanity, He does not give to the Church the Pope of which it needs, but leaves to the Church the Pope that it merits” (Archbishop Fulton Sheen).
