"Based on the Book of Mormon and the Bible, plus the revelations of Joseph Smith, the faith of Mormons is like that found in many conservative Protestant churches. However, certain aspects of the theology of Latter-Day Saints depart from the traditional orthodoxy of Catholic and Protestant churches: Three persons comprise the Godhead--the Father, the Son, and the Holy Ghost; the Father and the Son have bodies of flesh and bone, but the Holy Ghost is a personage of Spirit. . ."

"Jesus is the Firstborn. Obviously, he did not have this distinction as pertaining to his birth into mortality, for many millions preceded him in birth upon this earth. But it must not be forgotten, however little the doctrine is known and believed in the present so-called Christian world, that all men lived in a pre-existent estate before they were born into this world; all were born in pre-existence as the spirit children of the Father. Christ was the Firstborn Spirit Child, and from that day forward he has had, in all things, preeminence . . . . .He is the Son of God, literally, actually, as men are the sons of mortal parents . . ."
