Here’s a Newman quote for you:

If Christianity is both social and dogmatic, and intended for all ages, it must, humanly speaking, have an infallible expounder, else you will secure unity of form at the loss of unity of doctrine, or unity of doctrine at the lost of unity of form you will have to choose between a comprehension of opinions and a resolution into parties—between latitudinarian and sectarian error.

Read it a couple of times. It’s dynamite.
