Uh, Jews are NOWHERE near Christians, as they believe Christians follow a false Messiah...Mormons believe in some of the basic tenets of early Christianity and tend to reject a lot of Church-related beliefs, or it that Protestants...magritte
I was speaking in terms of theological belief: what does one believe about God (and by implication, our relationship to Him)? That is what defines a person as Christian or non-Christian, not superficial things like moral rules or religious practices that are outworkings of the foundational issues.
The issue of monotheism vs. polytheism alone is huge. Someone can say they believe in Jesus - but the Jesus of Mormonism is just one of many godlings. Not the omnipotent, omniscient, omnipresent creator and sustainer of the universe, the sole source of a transcendant moral order, etc. At least Jews and Christians share a very similar understanding of the attributes of God and that we need to be reconciled through a divinely provided messiah.
Mormons do not believe in the tenets of early Christianity so much as they believe the tenants of Gnosticism.
And yes, I know you are Noachide.
