[patent]

Can a pope trump another pope? Who wins when a living pope directly contradicts a dead pope who is also a saint? Who wins when a living pope directly contradicts an infallible statement by a previous pope?

Please produce a statement by a living Pope contradicting an infallible statement by a previous Pope. I don’t believe that a Pope can teach heresy.

"I don’t believe that a Pope can teach heresy."

I've always been taught that the Holy Ghost will prevent that. I don't recall the details but I recall the story of an atrocious, heretical Cardinal elevated to the Papacy who tried to declare his heresies as truth and simply couldn't do it. He tried, he failed. I wish my memory worked better.
