… a solid track record of errors.
Even your bait and switch of impeccability with infallibility is a glaring error and a straw man. Nobody advanced a claim that even a true Pope is impeccable.
Feel free to remain Stubborn in your errors. You will get no traction with errors.
Well Mark, at least I remain faithful to the dogma, so I at least have that going for me. Good luck if that's an error to you. But please consider that I'm not the one entrapped in a self imposed conundrum.
To say the pope is impeccable is to say the pope cannot sin, which is to deny the pope any possibility of ever preaching heresies, which is a sin.
Because Christ and the Church are one and the same, just as Christ cannot be destroyed, the Church can never be destroyed, another way to say this is to say that the Church is indefectible. I think even Lad "the indefectibilist" would agree with this, but maybe not, who knows?
Sedes usually believe or insist that the pope and the Church are one and the same because they confuse the head of the Church with it's vicar.
