Much truth to what you say. The human part within “religion” (that is, organizational) always becomes the issue. In the first 1000 years, there was apparently no question: The “Church” was a mysterious union, of Truth, a body of Christ, beyond the people running it, which each person chooses to participate in, or not. THAT is the entity that will never pass away.
(IMHO, Catholicism and Eastern Orthodoxy is/are not perfect as is, given people are involved, but closest to this ideal in practice — but remember - it’s a mystery.)
Mystery is right, Only God has the masters degree, the
rest of us are infants.
