Question for all - DL, Lad, Roman Theo, anyone: Where in Scripture does it say that our popes and bishops cannot teach error, error that might even "make void the commandment of God"?
Are we Prots now? There are lots of things that Scripture doesn't detail regarding ecclesiology, but which are in the Church's Tradition. Early in Church history, expression that "Peter has spoken; the matter is closed" was very widely used, and the teachings of the Church Fathers are that the Roman See can not err or be polluted with error.
This isn't about the strict limits of infallibility, as I have repeatedly pointed out. It is about the question of whether the Catholic Church can change so drastically that it would be unrecognizable to Catholics living 100 years ago and mistaken for a Protestant sect. This Conciliar Church lacks the marks of the Catholic Church, as Archbishop Lefebvre has repeatedly stated, and, agreeing with the Catholic Encyclopedia and pretty much every Catholic theologian in history, we hold that this is not possible, as it would be tantamount to a defection of the Church.
What the exact legal disposition is of the man sitting on the Chair in Rome, that can be debated, and frankly it's a sideshow distraction. Whether the see is vacant or "impounded" (Father Chazal) or whatever, that's not for us to dispose of. We simply know that we cannot be part of this institution. We don't belong there. We do not hear from Rome the "Voice of the Shepherd" and do not recognize their Magisterium as the Catholic Magisterium. That's why we're Traditional Catholics. If I thought that Conciliar Church was the Church, I'd never dream of abandoning it but would rather be at some FSSP chapel smelling the smells and hearing the bells.
See, when you have an institution that Catholics simply don't recognize as Catholic and that you must stay away from to please God and keep the faith, if that wouldn't constitute a defection of the Church, then nothing would.
Catholic Encyclopedia:
Among the prerogatives conferred on His Church by Christ is the gift of indefectibility. By this term is signified, not merely that the Church will persist to the end of time, but further, that it will preserve unimpaired its essential characteristics. The Church can never undergo any constitutional change which will make it, as a social organism, something different from what it was originally. It can never become corrupt in faith or in morals; nor can it ever lose the Apostolic hierarchy, or the sacraments through which Christ communicates grace to men. The gift of indefectibility is expressly promised to the Church by Christ, in the words in which He declares that the gates of hell shall not prevail against it. It is manifest that, could the storms which the Church encounters so shake it as to alter its essential characteristics and make it other than Christ intended it to be, the gates of hell, i.e. the powers of evil, would have prevailed. It is clear, too, that could the Church suffer substantial change, it would no longer be an instrument capable of accomplishing the work for which God called it in to being.
We see a Conciliar Church that has corrupted doctrine (both of faith and, with Bergoglio, also now of morals), that has an official public worship that displeases God and is worse than a lot of what the Prots came up with in terms of Liturgy, that has a huge pool of bogus saints, including the destroyers themselves (the greatest uninterrupted line of saint popes since the early martyr popes, despite their responsibility for the greatest decay of the Church in history) ... and you are trying to tell me that's the Catholic Church. You might as well be calling my mother a whore ... and you are.
So please take your nonsense somewhere else. Stop playing your game with splitting hairs about the strict limits of infallibility. This goes WAY BEYOND THAT. If there hadn't been a New Mass and new Sacraments and all the bogus saints, there likely would be only a very small Traditional movement. But the overall perception we have of the Conciliar Church ... that monstrosity is simply unrecognizable as the Church.
