Hey, hon. I'm sure you realize that for 40 year back in the Great Western Schism there were 2, and sometimes 3 simultaneous claimants for the title of Pope. Some people later recognized as saints (e.g. St. Vincent Ferrar, and he's not the only one) spent their whole adult lives backing the wrong horse.
None of this historic confusion makes it impossible to live a good and holy Catholic life. Harder, I'll grant you, but not impossible.
As the people you yourself cited said: we are talking about the *Faith* if Peter. Not some one-man oracle.
You keep making my point!
You keep making my point! No; you keep changing your 'point'.
Rome doesn't teach NOW what it taught back THEN; no matter how many red herrings get drug across the trail or how many rabbit holes are claimed to be enticing enough to explore.
