Let's examine what the leaders of the Church taught about the "Virgin" birth.

-Joseph Smith taught that God had sex with Mary...

"President Young spoke of the first organization of this school by Joseph Smith the Prophet. The Word of Wisdom was given in this school. President Young said Adam was Michael the arch angel and he was the father of Jesus Christ and was our God and that Joseph taught this principle."  Wilford Woodruff Journal, Vol.4, p.288, September 17, 1854

-There was nothing figurative about His paternity... 

“And Christ was born into the world as the literal Son of this Holy Being; he was born in the same personal, real, and literal sense that any mortal son is born to a mortal father. There is nothing figurative about his paternity; he was begotten, conceived and born in the normal and natural course of events,...Christ is the Son of Man, meaning that his Father (the Eternal God!) is a Holy Man.” Bruce R. McConkie, Mormon Doctrine, 1966, p. 742

-He was concieved in the normal way...

"Their testimony is that Mary's son is God's Son; that he was conceived and begotten in the normal way; that he took upon himself mortality by the natural birth processes; that he inherited the power of mortality from his mother and the power of immortality from his Father-in consequence of all of which he was able to work out the infinite and eternal atonement." Bruce R. McConkie, The Promised Messiah: The First Coming of Christ, p.472

-The Son of God in the literal sense...

"The Church of Jesus Christ of Latter-day Saints proclaims that Jesus Christ is the Son of God in the most literal sense. The body in which He performed His mission in the flesh was sired by that same Holy Being we worship as God our Eternal Father. Jesus was not the son of Joseph, nor was He begotten by the Holy Ghost. He is the Son of the Eternal Father!" President Ezra Taft Benson, Come Unto Christ, p. 4

-Heavenly Father was the Father of His body...

"Now, we are told in scriptures that Jesus Christ is the only begotten Son of God in the flesh. Well, now for the benefit of the older ones, how are children begotten? I answer just as Jesus Christ was begotten of his father ... Jesus is the only person who had our Heavenly Father as the father of his body." Prophet Joseph F. Smith, Family Home Evening Manual, 1972, pp.125,126

-The result of a natural action...

“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" (Ibid., vol. 8, p. 115)  President Ezra Taft Benson

-There was nothing unnatural about it...

"...I will say that I was naturally begotten; so was my father, also my Saviour Jesus Christ. According to the Scriptures, he is the first begotten of his father in the flesh, and there was nothing unnatural about it." Journal of Discourses, Heber C. Kimball, 8:211

-Same way mortal men are begotten by mortal fathers...

“These name-titles all signify that our Lord in the only Son of the Father in the flesh. Each of the words is to be understood literally. Only means only; Begotten means begotten; and Son means son. Christ was begotten by an Immortal Father in the same way that mortal men are begotten by mortal fathers.” Bruce R. McConkie, Mormon Doctrine,1966, pp. 546-547

-Not begotten by the Holy Ghost...

"When the virgin Mary conceived the child Jesus, the Father had begotten him in his own likeness. He was not begotten by the Holy Ghost" Brigham Young, Journal of Discourses, vol. 1, p. 50

-Instead of letting any other man do it... 

"When the time came that His first-born, the Saviour, should come into the world and take a tabernacle, the Father came Himself and favoured that spirit with a tabernacle instead of letting any other man do it. The Saviour was begotten by the Father of His spirit, by the same Being who is the Father of our spirits." (Ibid., vol. 4, p. 218)

-Associated together in the capacity of husband and wife...

"It was the personage of the Father who begat the body of Jesus; and for this reason Jesus is called 'the Only Begotten of the Father;' that is, the only one in this world whose fleshly body was begotten by the Father.. The fleshly body of Jesus required a Mother as well as a Father. Therefore, the Father and Mother of Jesus, according to the flesh, must have been associated together in the capacity of Husband and Wife; hence the Virgin Mary must have been, for the time being, the lawful wife of God the Father. God having created all men and women, had the most perfect right to do with His own creation, according to His holy will and pleasure: He had a lawful right to overshadow the Virgin Mary in the capacity of a husband, and beget a Son, although she was espoused to another; for the law which He gave to govern men and women was not intended to govern Himself, or to prescribe rules for His own conduct. It was also lawful in Him, after having thus dealt with Mary, to give her to Joseph her espoused husband. Whether God the Father gave Mary to Joseph for time only, or for time and eternity, we are not informed. Inasmuch as God was the first husband to her, it may be that He only gave her to be the wife of Joseph while in this mortal state, and that He intended after the resurrection to again take her as one of His own wives to raise up immortal spirits in eternity" Apostle Orson Pratt, The Seer, p. 158

-He was not born without the aid of man...

"Our Father in heaven is the Father of Jesus Christ, both in the spirit and in the flesh..I believe firmly that Jesus Christ is the Only Begotten Son of God in the flesh..not as the Son of the Holy Ghost, but the Son of God..Christ was begotten of God. He was not born without the aid of Man, and that Man was God!" President Joseph Fielding Smith, Doctrines of Salvation, vol. 1. p. 18

-As you and I are the sons of our fathers...

"We believe absolutely that Jesus Christ is the Son of God, begotten of God, the first-born in the spirit and the only begotten in the flesh; that He is the Son of God just as much as you and I are the sons of our fathers.” President Heber J. Grant, Millenial Star, p. 2

-Mary the wife of Joseph had another husband...

"The man Joseph, the husband of Mary, did not, that we know of, have more than one wife, but Mary the wife of Joseph had another husband." Brigham Young, Journal of Discourses, 11:268

-He was actually, literally, biologically the Son of God...

"Jesus Christ was willing to make payment because of his great love for mankind, and he was able to make payment because he lived a sinless life and because he was actually, literally, biologically the Son of God in the flesh." Messages for Exaltation, pp.378-379

-Adam was the father of Jesus...

-God as the literal father of the human family...

 "Latter-day revelation confirms the biblical account of God as the literal father of the human family." Bible Dictionary back of the Book of Mormon, under the heading God, 1990 printing, p.682

-Jesus Christ was not begotten by the Holy Ghost...

''When the Virgin Mary conceived Jesus, the Father had begotten him in his own likeness. He was not begotten by the Holy Ghost...'What a learned idea' Jesus, our elder brother was begotten in the flesh by the same character that was in the garden of Eden, and who is our Father in heaven." 'Now Remember from this time forth, and forever, that Jesus Christ was not begotten by the Holy Ghost. I will repeat a little anecdote. I was in conversation with a certain learned professor upon this subject when I replied to this idea-

 "If the son was begotten by the Holy Ghost, it would be very dangerous to baptize and confirm females and give the Holy Ghost to them, lest he should beget children to be palmed off on the Elders by the people, bringing the Elders into great difficulties."...But what do the people in Christendom, with the Bible in their hands, know but this subject? Comparatively Nothing."—Brigham Young, Journal of Discourses, Vol. 1:50-51

-That first man sent his own son to redeem the world...

"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, vol. 4, p. 1

-Was begotten of his father, as we were of our fathers...

 "The birth of the Savior was as natural as are the births of our children; it was the result of natural action. (Adam) He partook of flesh and blood - was begotten of his Father, as we were of our fathers." Journal of Discourses, Brigham Young, 8:115

-"The Devil, the mighty Lucifer...the brother of Jesus..."

-Elohim is literally the father...of the body in which Jesus...

 "Jesus Christ is the Son of Elohim both as spiritual and bodily offspring; that is to say, Elohim is literally the Father of the spirit of Jesus Christ and also of the body in which Jesus Christ performed His mission in the flesh..." James Talmage, The Articles of Faith, pp. 466-467

-In the same way mortal men are begotten...

"Christ was Begotten by an immortal Father in the same way that mortal men are begotten by mortal fathers." Bruce McConkie, Mormon Doctrine, 1966, pg.547

-Defending the doctrines of men...

 "They tell us the Book of Mormon states that Jesus was begotten of the Holy Ghost. I challenge that statement. The Book of Mormon teaches No Such Thing! Neither does the Bible!" —Joseph Fielding Smith, Doctrines of Salvation, Vol. 1:18

Virgin Birth

 "When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost." Matt 1:18

"Joseph, thou son of David,fear not to take unto thee Mary thy wife: for that which is concieved in her is of the Holy Ghost." Matt 1:20

-Mormons preach a false Christ.

"Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us." Matthew 1:23

“God with us” is literally true, “the Word was made flesh, and dwelt among us.” John 1:14

"Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive,” Isaiah 7:14

"But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Ghost. " Matthew 1:20  Of the Holy Ghost not Elohim.

"And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things. Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves: Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen."             Romans 1:23-25

 This is America. You can worship your cat if you want too. Let's be clear that Cat Worship is not Christianity. The biggest sin of the LDS Church is their claim that they're Christian. If you believe that God the Father had a body, and had sex with Mary. You are NOT a Christian. Please let me explain, if Jesus of Nazareth was not born of a Virgin, then he did not fulfill the prophecy of Isaiah, and he is not the Christ. It's just that simple. He would not be the Messiah that we are waiting for. 

Claiming that the title "Virgin" means something other than a woman who has never had sex, is Clinton-esque, and clearly contradicts the Apostle Matthew. (See above, Matthew 1:20. See  alsoThe Words of Isaiah)

 Claiming that God the Father was an exalted being and exalted sex is some how different than earthly sex makes a liar of the so called "modern LDS Prophets", who explain it very clearly. It is "another Gospel" (Gal 1:6-9) and a "false Christ". 

Jesus said; “Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.” 1 Cor 6:9-10

 A false Christ cannot save you!  If you worship a false Christ you have no salvation.
