Mormon Doctrine, pg. 822; “Our Lord is the only mortal person ever born to a virgin, because he is the only person who ever had an immortal Father. Mary, his mother, “was carried away in the Spirit” (1 Ne. 11:13-21), was “overshadowed” by the Holy Ghost, and the conception which took place “by the power of the Holy Ghost” resulted in the bringing forth of the literal and personal Son of God the Father. (Alma 7:10; 2 Ne. 17:14; Isa. 7:14; Matt. 1:18-25; Luke 1:26-38.) Christ is not the Son of the Holy Ghost, but of the Father. (Doctrines of Salvation, vol. 1, pp. 18-20.) Modernistic teachings denying the virgin birth are utterly and completely apostate and false.”

Isaiah 7:14; “Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel.”

Someone is lying.  They’ve told us that Mary had sex with God and now they’re telling us that it was through the Holy Spirit so how could you ever trust anything they say?
