Critics of The Church of Jesus Christ of Latter-day Saints sometimes proclaim that the LDS believe that God had sex with Mary, resulting in the conception of Jesus. This is simply not true. While some members of the Church may have speculated concerning the conception of Jesus, the Church has never had a teaching concerning this event. This can easily be seen in a letter written by President Harold B. Lee to a brother in Logan, Utah. The letter is reproduced below. An edited version is also quoted in The Teachings of Harold B. Lee (Salt Lake City: Bookcraft, 1996), 14.

Dear Brother Bracken:
We are very much concerned that some of our Church teachers seem to be obsessed of the idea of teaching doctrine which cannot be substantiated and making comments beyond what the Lord has actually said.
You asked about the Immaculate Conception of the birth of the Savior. Never have I talked about “sexual intercourse” between Deity and the mother of the Savior. If teachers were wise in speaking of this matter about which the Lord has said but very little, they would rest their discussion on this subject with merely the words which are recorded on this subject by Luke 1:34-35:
“Then said Mary unto the angel, How shall this be, seeing I know not a man? And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God.”
Remember that that being who brought about the Immaculate Conception was a divine personage. We need not question his method to accomplish his purposes. Perhaps we would do well to remember the words of Isaiah 55:8-9:
“For my thoughts are not your thoughts, neither are your ways my ways, saith the Lord. For us the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.”
Let the Lord rest His case with this declaration and wait until he sees fit to tell us more.
