I don't see how there being a divinely anointed individual who receives, under proper situations, infallible direction from God, is any more "once finding a view that invests themselves with divine authority" than is writing a book of fables and history and then saying that is the divine authority.

The Catholic position is entirely unproblematic a priori if theism itself is. One still needs arguments that it's correct in detail (that's what apologetics is for), but your style of comment just doesn't work as a critique.

Either go for atheism wholesale, or you have to get into the nitty gritty of why Catholics ought or ought not be the source of divine authority within a reality where it's accepted that divine authority is a thing that really happens (or could happen).
