From “Why Catholic conversion narratives?”

Imagine: The Pope doesn’t have a story about how he became Catholic. No one would take that as evidence (I don’t think) that he’s not really. If I were to ask, e.g., “is the Pope really a Catholic?”, no one would answer with his conversion story. The evidence I’d be understood as asking for isn’t a story about how he chose Catholicism. There’d be certain acts or facts that would count as evidence in that case.
