To acquire validity for the appointment. He's saying that the appointment of heretics is not valid even if they're validly consecrated
JAM posted: "Orally, the Holy Father detailed first of all, all the powers which he was giving, including the choice of priests to consecrate and to confer on them the episcopacy without their having need of pontifical bulls, nor therefore to give their signatures engaging themselves to conform to such under oath..... In a word We grant you all the pontifical powers of the Pope himself, which are not by Divine Law incommunicable."
cuм ex says that for those who have ever deviated from the faith, "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; it shall not be possible for it to acquire validity...."
So per cuм ex, +Thuc, having been detected of deviating from the faith, lost his supposed
appointment read:
elevation of universal jurisdiction, a jurisdiction normally reserved only to the bishop of Rome.
So I was wrong in what cuм ex said - it says nothing about invalid consecrations.
