In any case, theological and historical differences betwenn Eastern (or, even, Oriental) Orthodox and most Protestant churches might be huge, but they pale in comparison between the differences between even most evangelical churches and the Mormons. On the bulk of what they believe in Orthodox, Catholics, Anglicans, Lutherans, Baptists, etc., etc. are fairly close - while Mormons are almost as distinct from them all as are the Muslims.
This. If we're considering Mormons Christians, should we also consider Muslims Christian because they view Jesus as a Prophet, believe that he had a virgin birth, and believe in his Second Coming?
Furthermore, Mormons:
- don't believe in Apostolic Succession
- view the three personages of the trinity as fully separate personages rather than as three cosubstantial personages in one being
- Mormons believe that God the Father is only one of countless Gods, and that he
used to be a man who lived on another planet
