Unbelievable idiocy. Only when the Vicar of Christ speaks ex cathedra in collaboration with the bishops that a teaching becomes infallible. Otherwise the Pope’s comments are open to disagreement.
I know y’all don’t like Unam Sanctam. There is no wiggle room under that proclamation. You have to be subject to the pope. If it’s wrong then the pope was in error. Are you prepared to say that?
