This is in response to a commenter on Elena's blog that my list of bullet points was incorrect and that I had been "misled"

Here are the points and my sources:

• Mormon doctrine denies the eternal nature of God (the father-god was a created man who became a god)

As god once was, man is. As God is, man may become." (See The Teachings of Lorenzo Snow, comp. Clyde J. Williams, Salt Lake City: Bookcraft, 1984, p. 1)

• Mormon doctrine denies the Trinity )"That these three are separate individuals, physically distinct from each other, is demonstrated by the accepted records of divine dealings with man." (Articles of Faith, by James Talmage, p. 35.)

Source: Joseph Smith: "Lectures on Faith.", approved for inclusion in the Doctrine and Covenants by a Conference vote of the LDS Church on August 17, 1835. They appeared in all English editions of the D&C until their unexplained removal in 1921 without a General Conference vote. Lecture Five explicitly teaches that there are two persons in the Godhead:

Q. How many personages are there in the Godhead?
A. Two: the Father and the Son.

• Mormon doctrine denies the virgin birth (the father-god had sex with Mary to conceive Jesus)

Brigham Young, second prophet and president of the LDS church said,

"The birth of the Saviour was as natural as are the births of our children; it was the result of natural action. He partook of flesh and blood—was begotten of his Father, as we were of our fathers." (Journal of Discourses, v. 8, p. 115).

• Mormon doctrine teaches that Christ was in a plural marriage

Jedediah M. Grant, Second Counselor to Brigham Young the Second Prophet of the LDS Church:

"Celsus was a heathen philosopher; and what does he say upon the subject of Christ and his Apostles, and their belief? He says, the 'grand reason why the Gentiles and philosophers of his school persecuted Jesus Christ, was because He had so many wives; there were Elizabeth, and Mary, and a host of others that followed Him.' After Jesus went from the stage of action, the Apostles followed the example of their master. . . The grand reason of the burst of public sentiment in anathemas upon Christ and his disciples, casing his crucifixion, was evidently based on polygamy,. . .a belief in the doctrine of plurality of wives caused the persecution of Jesus, and his followers. We might almost think they were 'Mormons' " (Journal of Discourses, Vol 1. ppl 345-346)

• Mormon doctrine teaches that Mormonism is the only true way to heaven
• Mormon doctrine states that there is no salvation without accepting Joseph Smith as a prophet of God, (Doctrines of Salvation, Vol. 1, p. 188.)

If it had not been for Joseph Smith and the restoration, there would be no salvation. There is no salvation [the context is the full gospel including exaltation to Godhood] outside the church of Jesus Christ of Latter-day Saints, (Mormon Doctrine, p. 670.)

• Mormon doctrine teaches that all men have the potential to become gods

As god once was, man is. As God is, man may become." (See The Teachings of Lorenzo Snow, comp. Clyde J. Williams, Salt Lake City: Bookcraft, 1984, p. 1)

• And it follows that Mormon doctrine denies monotheism (as there are as many gods as there are men who have become gods)

We were begotten by our Father in Heaven; the person of our Father in Heaven was begotten on a previous heavenly world by His Father; and again, He was begotten by a still more ancient Father, and so on from generation to generation, from one heavenly world to another still more ancient...
