Bring me up to your "flipping league," I bid you please kind superior person of very elaborately complex yet oddly immoral in practice religion.

Basically, from the beginning till now, when a Pope solemnly officially defines something as a dogma, it’s infallible. When he just says what his opinion is as a person, *even if it’s theological*, then it’s not.
Peter was the head of the Apostles with the power to bind and loose and the keys to the Kingdom of Heaven, but that didn’t mean that Paul—who had none of those things—couldn’t correct him. Same principle here.
