This is what Mormons believe about the God of the Bible:
God used to be a man on another planet, Mormon Doctrine, p. 321. Joseph Smith, Times and Seasons, Vol 5, pp. 613-614; Orson Pratt, Journal of Discourses, Vol 2, p. 345, Brigham Young, Journal of Discourses, vol. 7, p. 333.)
The Father has a body of flesh and bones as tangible as man’s... (D&C 130:22).
God is in the form of a man, (Joseph Smith, Journal of Discourses, Vol. 6, p. 3.)
God himself was once as we are now, and is an exalted man, and sits enthroned in yonder heavens . . . We have imagined that God was God from all eternity. I will refute that idea and take away the veil, so that you may see (Teachings of the Prophet Joseph Smith, p. 345
God the Father had a Father, (Joseph Smith, History of the Church, vol. 6, p. 476; Heber C. Kimball, Journal of Discourses, vol. 5, p. 19; Milton Hunter, First Council of the Seventy, Gospel through the Ages, p. 104-105.)
God resides near a star called Kolob, (Pearl of Great Price, pages 34-35; Mormon Doctrine, p. 428.)
God had sexual relations with Mary to make the body of Jesus, (Brigham Young, Journal of Discourses, Vol. 4, p. 218, 1857; vol. 8, p. 115.) - This one is disputed among many Mormons and not always 'officially' taught and believed. Nevertheless, Young, the 2nd prophet of the Mormon church taught it.
Therefore we know that both the Father and the Son are in form and stature perfect men; each of them possesses a tangible body . . . of flesh and bones. (Articles of Faith, by James Talmage, p. 38).
GOD, BECOMING A GOD
After you become a good Mormon, you have the potential of becoming a god, (Teachings of the Prophet Joseph Smith, pages 345-347, 354.)
Then shall they be gods, because they have no end; therefore shall they be from everlasting to everlasting, because they continue; then shall they be above all, because all things are subject unto them. Then shall they be gods, because they have all power, and the angels are subject unto them, (DC 132:20).
GOD, MANY GODS
There are many gods, (Mormon Doctrine, p. 163.)
And they (the Gods) said: Let there be light: and there was light (Book of Abraham 4:3)
GOD, MOTHER GODDESS
There is a mother god, (Articles of Faith, by James Talmage, p. 443.)
God is married to his goddess wife and has spirit children, (Mormon Doctrine p. 516.)
Do you still believe they worship the same God as me?
