>that has kept his Tradition alive through the centuries and alive fundamentally unchanged
the answer to which is an emphatic, "No." Which is why Protestantism exists in the first place.
The fundamental conundrum is whether or not you believe god is operating through people who are clearly behaving in self-serving ways, as many Catholic officials have in the past. There's nothing empirical about such a question and no use becoming indignant over some taking the perfectly sentimental (if not also reasonable, though that's beside the point) stance that they simply don't trust those dudes. The appeal to being the Church which is Jesus who is God, and therefore you can't question anything a church official says, is, like... the whole point of tension.
