You will never learn Mormon doctrine from their Articles of Faith. Those are written to hide their teachings from "gentile" readers. You must look into their secret temple ceremonies and the writings of their prophets. Here are some of the surprising results.
Mormons place the bible second to their own writings.
Mormon scripture consists of four books. They are: (1) The Book of Mormon (2) Doctrine and Covenants (3) Pearl of Great Price and (4) The Bible (in that order). The first three books seriously contradict the Bible. Mormons often ignore the Bible, claiming it is "mis-translated."
No man can come to God without Joseph Smith
Joseph Smith was God's prophet. "No man can come to Christ except through Joseph Smith."
Prophets are better than Scriptures. The words of a Mormon prophet supercede those of the written Scriptures.
God was once a man who progressed to Godhood. Mormons believe we can do the same. Their God has a physical body of flesh and bone.
There are many gods in heaven. God the Father, Son and Holy Ghost are supposedly separate gods, united only in purpose.
God is having kids, and other heresy
Surrounded by what must be 1,000 or more wives, God is having little spirit babies which will inhabit the people born on the earth.
The number of babies this requires Him to produce daily is incredible!
No explanation is given why their God of flesh and bone, having babies through physical sexual contact with his wives, has only spirit babies. They teach that Mary married God to have Jesus (or else He would have been illegitimate) and then divorced him to marry Joseph.
Dark skin results from a "curse" placed upon certain spirits, presumably for some failure during "pre-existence." This anti-Negro doctrine is an embarrassment for Mormon leaders, and they are under great pressure to change it.
Women need husbands for resurrection at the end of time. Without a man to "lift the veil" over her face on resurrection day she won't make it.
She is desperate to see her husband remain a true Mormon so she may be resurrected. Women's liberation has not made great inroads here.
Jesus had many wives. They say Mary and Martha were among his wives. One Mormon authority said Jesus was killed for his polygamy.
The Book of Mormon is infallible. Mormon Articles of Faith say, "We believe the Bible to be the Word of God as far as it is translated correctly: we also believe The Book of Mormon to be the Word of God." They claim anything in the Bible which denies Mormon teaching is "incorrectly translated." source - Chick Publications

What The Mormon Church Won't Tell You
"But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. As we said before, so say I now again, If any [man] preach any other gospel unto you than that ye have received, let him be accursed. " Galatians 2
Most of us have had a Mormon Missionary knock at our door. If you have ever invited them in and listened to a presentation of their beliefs, you probably found most but not all of what they said very similar to those beliefs held by Christians.
Watch this animated video taken directly from Mormon doctrine and teachings. See how much YOU agree with.
However, while trying to convince you that your Church is wrong and the Mormon Church is right, there are several points they intentionally leave out.
Below is a list of Mormon beliefs the missionaries will be reluctant to tell you about:
God was not always God - "We have imagined and supposed that God was God from all eternity. I will refute that idea, and take away the veil, so that you may see." (Teachings of the Prophet Joseph Smith, pg. 345)
Jesus and Satan are brothers - "The appointment of Jesus to be the Savior of the world was contested by one of the other sons of God. He was called Lucifer, son of the morning. Haughty, ambitious, and covetous of power and glory, this spirit-brother of Jesus desperately tried to become the Savior of mankind." (Milton R. Hunter, Gospel Through the Ages, pg.15)
Jesus was a polygamist -"I discover that some of the Eastern papers represent me as a great blasphemer, because I said, in my lecture on Marriage, at our last Conference, that Jesus Christ was married at Cana of Galilee, that Mary, Martha, and others were his wives, and that he begat children." (Orson Hyde, Journal of Discourses 2:210)
The grand reason of the burst of public sentiment in anathemas upon Christ and his disciples, causing his crucifixion, was evidently based upon polygamy, according to the testimony of the philosophers who rose in that age. A belief in the doctrine of a plurality of wives caused the persecution of Jesus and his followers. We might almost think they were 'Mormons'" (Jedediah M. Grant, Journal of Discourses, 1:346)
Adam was God - "Now hear it, O inhabitants of the earth, Jew and Gentile, Saint and sinner! 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 organize 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, Journal of Discourses 1:50)
"I have learned by experience that there is but one God that pertains to this people and he is the god that pertains to this earth--The first man. That first man sent his own son to redeem the world..."(Heber C. Kimball, Journal of Discourses 4:1)
Brigham Young said only polygamists become gods - "The only men who become Gods, even the Sons of God, are those who enter into polygamy." (Journal of Discourses 11:269)
The bible cannot be trusted -
"I believe the Bible as it read when it came from the pen of the original writers. Ignorant translators, careless transcribers, or designing and corrupt priests have committed many errors." (Teachings of the Prophet Joseph smith, pg.327)
"But the Bible has been robbed of its plainness; many sacred books having been lost, others rejected by the Romish Church, and what few we have left, were copied and recopied so many times, that it is admitted that almost every verse has been corrupted and mutilated to that degree that any two of them read alike." (Orson Pratt, The Seer, pg.213)
You must accept Joseph Smith as a prophet to be saved - "There is "no salvation without accepting Joseph Smith. The word "salvation," used in this context, must really mean "exaltation" because former Mormon apostle Bruce R. McConkie stated in his book Mormon Doctrine that general salvation is given to everyone regardless of belief. Personal salvation or exaltation to the highest form of Mormon heaven comes only by accepting Joseph Smith as a prophet of god and by following the laws of the LDS church." (Tenth LDS President Joseph Fielding Smith in his book, Doctrines of Salvation)
