No. Not all the sincerity in the world can be a sufficient substitute for authentic credentials in this matter. An immense power and authority over the souls of men requires solid proof that it is really possessed. Christ proved that He had it. The Catholic Church can prove that He entrusted that power to Her. Founders of other churches had no more than their own personal conviction that they possessed such authority—a persuasion as insufficient as would be my own personal belief that I had the authority of the Chief Justice in the land.
