BoM 1 Nephi 11, narrates a vision of Nephi. He sees the virgin Mary (v. 15-18), and then he "beheld that she was carried away in the Spirit;" (v. 19) and after a time he sees her "bearing a child in her arms" (v. 20)

"The birth of the Saviour was as natural as are the births of our children; it was the result of natural action. He ...was begotten of his Father, as we were of our fathers." (JoD 8:115)

"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 husabnd... That very babe that was cradled in the manger, was begotten, not by Joseph, the husband of Mary, but by another Being. Do you inquire by whom? He was begotten by God our heavenly Father." (JoD 11:268)

Apostle Bruce R. McConkie wrote: "Christ was begotten by an Immortal Father in the same way that mortal men are begotten by mortal fathers." ( Mormon Doctrine , 1966 ed, 546-547)

"He [Jesus] is the Son of God in the same sense and way that we are the sons of mortal fathers. It is that simple." (The Promised Messiah, pp 467-468).
