Yawn...No salvation outside the Catholic Church is what he is saying. No Catholic is obligated to obey every utterance of the Pope. Furthermore, we declare, we proclaim, we define that it is absolutely necessary for salvation that every human creature be subject to the Roman Pontiff.
I see no allowances for what you assert.
You will note Unam came much later than Irenaeus.
But perhaps you're one of the RCs who doesn't believe your current pope, and he is your pope, is legit. Are you one of those?
Again, For Salvation, one must be in the Church and subject to its authority. Supreme authority is the Pope. Francis is a legitimate Pope, but a bad one. “There are not one hundred people in the United States who hate The Catholic Church, but there are millions who hate what they wrongly perceive the Catholic Church to be.” ― Fulton J. Sheen
Oh, no, he’s the legitimate pope all right, just happens to also be a disaster.
