OK, so unless my understanding of Mormon doctrine is wrong, then you are saying that they are not true Christians.
Well, if you can show where the Mormon understanding of Christ is different than that in the scriptures, then perhaps you have a point. I am saying that Mormons follow scripture information about Christ, profess Him to be the Only Begotten Son of God, the only way to the Father, the Savior and Redeemer of this world so what makes them non-Christian?
