Mormonism abreviated

The first thing that matters to me is 'the Priesthood' - though, the first important piece might be 3 Nephi 11 (LDS count) - a.k.a. the appearance of Christ amongst the Nephites or more specifically: The Doctrine of Christ.

This Doctrine refers to an 'authority' that is required to Baptize.

My Testimony tells me that the Church is true, but the vision I had along with that tells me that only in about a third of it is actually true. However - I now believe that what substanciates the Mormon Churches claim to be 'the true Church' is a matter of the Priesthood - as any other of their positions couldn't really hold their own.

And to answer the questions that arise from this condition - there's "the Strange Act" (D&C 95:4, 101:95)
