Mormonism - "Gods Many" Polytheism #3: Mormon Doctrines - Men Shall Become Immortal P

Mormonism denies that there is only one God in all existence and also denies the forgiveness of sins alone in Christ alone. Therefore, it is outside Christianity. It is not a Christian religion.
Mormonism teaches . . .

Mormonism teaches that God the Father has a body of flesh and bones (D. & C. 130:22) and that Jesus is a creation who was begotten in heaven as one of God's spirit children (See the book, Jesus the Christ, by James Talmage, p. 8). This is in strict contrast to the biblical teaching that he is God in flesh (John 1:1, 14), eternal (John 1:1, 2, 15), uncreated, yet born on earth (Col. 1:15), and the creator of all (John 1:3; Col. 1:16-17). Jesus cannot be both created and not created at the same time. Though Mormonism teaches that Jesus is God in flesh, it teaches that he is "a" god in flesh, one of three gods that comprise the office of the Trinity (Articles of Faith, by Talmage, pp. 35-40). These three gods are the Father, the Son, and the Holy Ghost. This is in direct contradiction of the biblical doctrine that there is only one God (Isaiah 43:10; 44:6, 8; 45:5). See Trinity for a correct discussion of what the Trinity is (see also, false trinity)

Because Mormonism denies the biblical truth of who God is, who Jesus is, how forgiveness of sins is attained, and what the gospel is, Mormonism is not Christian.
What else does Mormonism teach?

Mormon theology teaches that God is only one of countless gods, that he used to be a man on another planet, that he became a god by following the laws and ordinances of that god on that world, and that he brought one of his wives to this world with whom he produces spirit children.
