Short answer: most of it.

Longer answer: I’m a Gnostic Mormon. This means my own personal beliefs do not align 1:1 with LDS, I just think it’s the most theologically correct and practical church in the US today. The chief objection LDS holds with the Apostle’s creed, which I personally agree with, is a rejection of early Orthodoxy’s claim to authority in the first place. This ecumenism is considered apostate. Look up the Great Apostasy.
