"Origin of Elohim (God the Father)
"According to Mormon theology, God the Father is a physical being of "flesh and bones." Mormons identify him as the Biblical god Elohim. Latter-day Saint leaders have also taught that God the Father was once a mortal man who has completed the process of becoming an exalted being. According to Joseph Smith, God "once was a man like one of us and…once dwelled on an earth the same as Jesus Christ himself did in the flesh and like us.
"Origin of Jehovah (Jesus)
"According to Mormon belief, Jesus is identified as the god Jehovah (Yahweh). The pre-mortal Jehovah was born to the Virgin Mary and was named Jesus. Jesus was the Son of God—the literal father of his physical body was God the Father. Because Jesus was the Son of God, he had power to overcome physical death. Because he lived a perfect and sinless life, Jesus could offer himself as an "infinite and eternal" sacrifice that would be required to pay for the sins of all of the other children of God.
"Adam/Michael, under the Adam–God doctrine
"According to Brigham Young, Adam was a god identified as the Biblical archangel Michael prior to his placement in the Garden of Eden. The pre-existent godhood of Adam/Michael is now repudiated by the LDS Church, but it is accepted by some adherents of Mormon fundamentalism. According to this interpretation of Young's teachings, Michael was a god who had received his exaltation and was residing on another planet. From that planet, he took Eve, one of his wives, to the Garden, where they became mortal by eating the fruit in the garden. Although the LDS Church has repudiated the Adam–God doctrine, the denomination's Endowment ceremony portrays this Adam/Michael as a participant with Jesus in the creation of the earth, under the direction of Elohim.
"Heavenly mother, the Holy Spirit, and other gods and goddesses
The official doctrine of the LDS Church includes the existence of "heavenly parents" (plural), which is generally understood to refer to the goddess Heavenly Mother, who exists alongside God the Father."
