What Is The Official Mormon/LDS Position On Non-LDS Christians

I (as an atheist) consider Mormons to be Christian. And I have to say, this is the nicest, most sensible idea of a Christian afterlife I’ve ever read.

Not true in my experience as a member for 40 years. I have never heard someone within the church refer to a Jew as a Gentile.

How many Christian denominations can you think of that deny the Trinity?

LDS- Tri-theism or Henotheism
Jehovah’s Witnesses- Arianism (Father creates Son & emanates impersonal Holy Spirit, Father Jehovah & Son Michael-Jesus then create everything else using energy of Holy Spirit)
Apostolic or Oneness Pentecostals- Modalism or Sabellianism (Father, Son & Spirit are three Roles or Manifestations of One God)
Armstrongist Churches of God- Binitarianism- (Two Persons- Father & Son- in One God, Spirit is Impersonal Energy)
