You may think you don't believe it, but the way your draw our your thesis, that's effectively what you're doing ... subjecting the Pope to the Council.
Decrees of the First Vatican Council
SESSION 4 : 18 July 1870
Chapter 3. On the power and character of the primacy of the Roman pontiff
Para 8
"Since the Roman pontiff, by the divine right of the apostolic primacy, governs the whole church, we likewise
teach and declare that he is the supreme judge of the faithful [52] , and that in all cases which fall under ecclesiastical jurisdiction recourse may be had to his judgment [53]. The sentence of the apostolic see (than which there is no higher authority) is not subject to revision by anyone, nor may anyone lawfully pass judgment thereupon [54] . And so they stray from the genuine path of truth who maintain that it is lawful to appeal from the judgments of the Roman pontiffs to an ecuмenical council as if this were an authority superior to the Roman pontiff."
I see no distinction between a coercive and discretionary judgement. Also, PaxChristi2 (Salza & Siscoe) is falsely assuming (just as XavierSem does) that there is in fact peaceful acceptance of the Conciliar popes. But that is now manifestly false and even now the man whom they claim to be pope is worshipping demons in the Vatican Gardens. Even the conservative Novus Ordo folks are coming to the realization that this man cannot be the pope. And even Salza & Siscoe admit that a pope who publicly severs the external bonds of unity with the Church would immediately and without a declaration fall from the papacy. So now the only question is whether or not there is sufficient evidence to conclude that Frank has publicly severed the bonds of unity. But there is no guidance from the theologians that only if a pope says, "I quit the Catholic Church" that then and only then could we conclude that he has fallen. I guarantee that S&S will fall into line with the SSPX clerics if ever they finally decide enough is enough and switch over to supporting the idea that Frank publicly and at least tacitly resigned his claim to the papacy. I think Salza and Siscoe are not principled in this regard. They are just going along with whatever the SSPX clerics decide and the SSPX clerics are nothing if not pragmatic. If they see the wind blowing towards the tacit resignation opinion, they will go along with it.
