I believe firmly that Jesus Christ is the Only Begotten Son of God in the flesh. He taught this doctrine to his disciples. He did not teach them that he was the Son of the Holy Ghost, but the Son of the Father. Truly, all things are done by the power of the Holy Ghost.
It was through this power that Jesus was brought into this world, but not as the Son of the Holy Ghost, but the Son of God. Jesus is greater than the Holy Spirit, which is subject unto him, but his Father is greater than he! He has said it. Christ was begotten of God. He was not born without the aid of Man, and that Man was God!
(Joseph Fielding Smith, Doctrines of Salvation, 1:18)
