All this is taken from the tract called The Plain Truth About Mormon's

To Big G, It's true, You Mormon's lay claim to being Christian but here is what Mormonism teaches which is far different from the Bible: Mormons teach that man can become God, and that God was once a man:

"God himself, the Father of us all, is a glorified, exalted immortal resurrected man!" (Bruce McConkie, Mormon Doctrine, pp. 322-23, 517, 643)
"...God himself was once as we are now and is an exalted man and sits enthroned in yonder heavens..." (Journal of Discourses, V6, P3, 1844)
"As man is, God once was: as God is, man may become." (Lorenzo Snow, quoted in Milton R. Hunter, the Gospel Through the Ages, pp. 105-106)

This is plain and simple heresy. Nowhere does the Bible say or imply that God was ever a man, or that man can become God! Malachi 3:6 says, "For I am the LORD, I change not..." How could this be true if God was once a man? Genesis 1:1 states that God existed "in the beginning" before man was ever created. John 4:24 states that God is a "spirit," and Jesus tells us in John 1:18 that no man has seen God at any time. Numbers 23:19 says that "God is not a man that he should lie; neither the son of man that he should repent." God has always been God, and no one has ever "become" God.

Read on:

The Deity of Jesus Christ is a fundamental doctrine of Christianity, yet the Mormons deny this truth. Exalting man to "god status" is apparently alright, but Jesus Christ is not acknowledged as the eternal Son of God in the Mormon church. The Mormon Jesus was a preexisting spirit who was exalted, just as Mormon followers hope to be exalted someday.

God is a Trinity (I Jn. 5:7), and the second Member of that Trinity is the Lord Jesus Christ. John 1:1 says that "the Word was God," and John 1:14 tells us that "the Word was made flesh." Jesus Christ is the Word incarnate, and John 1:1 tells us that the Word was God; so Jesus Christ is God.

Jesus allowed Thomas to address Him as "My Lord and my God" in John 20:28. In Isaiah 9:6, He is called "The mighty God" and "The everlasting Father," and we read in Micah 5:2 that Jesus is "from everlasting."

Our Lord allowed people to worship him in John 10:38 and in Matthew 14:33, and since He is "God with us" (Mat. 1:23) He also has power to forgive sins (Mk. 2:5). Jesus Christ is clearly Deity, yet this doctrine is denied by the Mormons.

The Bible declares, "To the law and to the testimony: if they speak not according to this word, it is because there is no light in them." (Isa. 8:20) However, the Mormon Church claims that other writings, such as the Book of Mormon and Joseph Smith's writings are also authoritative. In fact, Joseph Smith taught his people to doubt the accuracy of the Bible: "...it was apparent that many important points touching the salvation of men, had been taken from the Bible, or lost before it was compiled." (Teachings of the Prophet Joseph Smith, p. 10)

How funny it is and sad for all of you who choose to follow this cult of Mormonism that you would believe a man who plagerized the Holy Bible over 25,000 times (Joseph Smith) and then believe that he had devine interpretation know one else was privy too. But don't stop reading I have much more for you to see........

"...if any man espouse a virgin, and desire to espouse another, and the first give her consent, and if he espouse the second, and they are virgins, and have vowed to no other man, then he is justified; he cannot commit adultery...And if he have ten virgins given unto him by this law, he cannot commit adultery." (Doctrines and Covenants, 132:61, 62)

Jesus Christ held a slightly different view (Mark 10:6- 9). There is no way a man can be "one flesh" with more than one woman. A man and his wife are supposed to picture Christ and his church (Eph. 5:23-32), but this symbolism is shattered by the Mormon heresy of Polygamy.

Yes. Big G, I know your church has changed some of it's rulings in this area, but if you really wanted to have more than one wife your books still say you can. It's another funny thing how the LDS makes up rules as they go along, but you know God has never changed anything at all. Not once anywhere has the laws of God changed. As far as rule changing goes I find it quite humorous that for decades you mormon's weren't allowed to drink anything stonger than kool-ade, but now that Coca-cola is owned by Mormon's it is now harmless to drink and man does your follower's drink it like their making up for lost time. However, I have more facts about your religion for you to read.......

The Mormon book, The Pearl of Great Price, claims that all other Christian groups are "corrupt" and are an "abomination" in God's sight (Joseph Smith, 2:19). Such claims as this are based on the unscriptural assumption that the Lord Jesus Christ has a specific religious organization on the earth today, complete with a name, a membership, and a leadership, which makes up His "true church." This doctrine is found nowhere in God's word. Everyone who has received Christ as their Saviour is a member of His church, which is a spiritual body of born-again believers (Eph. 4:4; 5:23-32; Col. 1:18-24; Heb. 12:23; Rev. 19:7; 5:9-10; 21:9).

Mormons believe that one's salvation is based on such good works as baptism, good deeds, missionary work, and following Mormon teachings. In The Articles of Faith, by James Talmage, justification by faith in Jesus Christ is called a "pernicious doctrine" twice and he states that it has been "an influence for evil." (pp. 107, 480) Bruce McConkie once stated at Brigham Young University that a personal relationship with Jesus Christ is "improper and perilous" (Church News, March 20, 1982, p. 5)

Ephesians 2:8-9 says, "For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast." Romans 4:5 says that salvation comes to those who do not work for salvation, but believe on Jesus Christ instead!

Jesus Christ came into this world to lay down His sinless life for YOU--to pay for your sins because you couldn't. Jesus is your only hope for salvation. Only by receiving Him as your Saviour can you enter the gates of Heaven. There is no other way. "Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father but by me." (John 14:6) "Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved." (Acts 4:12)

The Lord Jesus Christ has come and PAID for your sins by shedding His own Blood on Calvary. By receiving Him as your Saviour, you can be WASHED from all your sins in His precious Blood (Rev. 1:5; Col. 1:14; Acts 20:28; I Pet. 1:18-19). Notice these important words from Romans 5:8-9: "But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us. Much more then, being now justified by his blood, we shall be saved from wrath through him."

Jesus PAID your way to Heaven! Your church cannot save you! Only by receiving Jesus Christ as your Saviour can you escape the damnation of Hell. Are you willing to forsake YOUR righteousness and receive Jesus Christ as your Saviour, your ONLY HOPE for Salvation? Romans 10:13 says, "Whosoever shall call upon the name of the Lord shall be saved." Romans 10:9 says, "That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved." Why not pray right now and ask the Lord to come into your heart and cleanse you from all sin? He will save you just as He promised.

And Lastly Big G here is this.......

The Mormons deny the Trinity and the existence of a literal burning Hell, yet they promote polytheism (many gods), baptism for the dead, and the notion that Jesus and Satan were originally spirit brothers! Friend, make no mistake about it--Mormonism is a dangerous cult. In the eyes of man, the Mormons seem very respectable, but the light of God's word reveals the true wolves behind the sheep clothing. Jesus said, "Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves." (Mat. 7:15) Don't look at their nice families, their clean-cut hair, and their friendly "missionaries." LOOK AT THEIR DOCTRINES! (I Tim. 4:1)

So if you really want to make your claim as a Christian and still follow your cultic religion then you will be going to hell. So like I said Mormon's are not Christians. Period!
