That's fair. It isn't outside the realm of possibility that the Pope and every previous Pope is and was a true agent of God (despite how historical issues around papal succession and legitimacy may complicate that story), and there's no way to logic your way into an answer on that one way or another.
Nevertheless, whether or not someone's particular doctrine agrees with the "long game of telephone" stance, I would suggest that a mindset which finds meaning in the teachings and institutions of one's religion independent of their divinity is a more straightforward path to prosocial behavior and inner peace. The idea that anyone should ever suffer genuine anguish or question their personal morals based on doubts of their assumptions about the metaphysical nature of the universe just seems alien and like a non sequitur to me, but from what I understand it's a very real struggle for some people.
