'Mormonism is not Christianity, and anyone who asserts differently is either ignorant or dishonest'Let's start with the basics. Ed Decker, a former Mormon priest who converted to "real" Christianity, author of a number of books and movies including "The God Makers" asserts in "Who's That Knocking at My Door?":
First, understand that the Mormon Church likes to refer to itself as a Christian Sect. Sect is defined as a separate doctrinal group within a larger group. But Mormonism is not a separate doctrinal group within the Christian body. It teaches a different God, a different Jesus, and a different Heaven and Hell. It places the validity of the Bible in serious doubt, and proclaims new and different "Holy Scriptures." Its eternal doctrines or "gospel" and master plan of salvation are directed by the god of this earth through a living "Prophet, Seer, and Revelator" to whom the members must demonstrate total obedience.
Mormonism is correctly categorized as a cult. Cult is defined as group or system of religious worship and ritual focusing on uncommon doctrine and a very esoteric deity … Mormonism uses the same terms that the Christian uses, but they are not the same in meaning.
If you ask a Mormon knowledgeable in their teachings who Jesus is to them, the answer is much different than to any traditional Christian. They believe Jesus is a created being, the spirit brother of Lucifer (now known as Satan) and one of many gods. For example, Walter Martin in "Kingdom of the Cults" reveals critical facts:
When our father Adam came into the garden of Eden, he came into it with a celestial body, and brought Eve, one of his wives, with him. He helped to make and organized this world. He is MICHAEL, the Archangel, the ANCIENT OF DAYS! about whom holy men have written and spoken – HE is our FATHER and our GOD, and the only God with whom we have to do" (Brigham Young, in the Journal of Discourses, 1:50).
Martin also pointed out that, "A careful examination of the Book of Mormon reveals that it contains thousands of words from the King James Bible. In fact, verbatim quotations, some of considerable length, have caused the Mormons no end of embarrassment for many years." It has also been materially changed more than 800 times with "new revelations" since it was first published – in just century and a half.
