| What does Catholicism have to do with "(American) conservative"? Some beliefs of Catholic faith are agreeable to American "conservatives" - "homosexuality bad, no abortion, no euthanasia". Others are music to the ears of American "liberals" - "help the poor and downtrodden, love the foreigner and everyone else, no capital punishment". But the church is the church. I don't see it as liberal or conservative. I suspect if you asked the pope, or cardinals or bishops, most would say the church is beyond such secular concerns and labels. It has been around for far longer than any political movement or country. And I'd bet good money that it outlasts all of them. > pushing views A religious leader espousing religious views? Shocker. > strongly opposed to Catholicism Literally wrong. Only the Pope can tell you what Catholicism is. You can take it or leave it but that's how it is. https://en.wikipedia.org/wiki/Papal_supremacy https://en.wikipedia.org/wiki/Papal_infallibility |
Ergo, some like St. Robert Bellarmine have argued for example if a pope were to teach heresy, he would immediately cease to be a pope; others have argued it impossible for a pope to ever teach heresy at all as this was something they believed God wouldn't allow.
So, if you were to see someone claiming to be pope and teaching error on infallible issues of faith and morals, you'd have to conclude logically they could not be a Catholic pope, from a Catholic standpoint.
