The same thing is conceptualized in
Mormonism, albeit a bit more graphically: that "Elohim - Mormonism's "god the father" - came to Earth to have sex with Mary to produce a human body for Mormonism's Jesus.
According to Mormonism, Elohim was once born a human like us on a distant planet Kolab where he lived up to the teachings of Mormonism, died, and in the afterlife was granted to become a "god" (by others before him), which entitled him to his own planet to populate and rule over as king. His many celestial goddesses, apparently once human woman who, too, were granted goddess-ship, were given to him to provide him endless celestial sex and to produce for him spirit children. Jesus, Lucifer, and others came about from such celestial sex. Herein is the foundation for Mormonism's polygamy.
After Adam and Eve were created (I guess out of thin air seeing that neither were born to any human parents) to start the human race on Earth, these spirit children were to be granted the privilege of entering the bodies of human babies at conception and be born humans with the opportunity to be faithful to Mormon doctrine and, if accepted, eventually be granted the privilege of becoming gods of their own planets themselves like their father Elohim.
At a heavenly council, Jesus' suggestions about Earth's new human race were chosen over Lucifer's, which angered him and led him to start a war -
- the spirits who fought valiantly against Lucifer got the privilege of being born white babies
- those who were indifferent in the battle were cursed to be black babies
- the rebellious spirits were cast out of heaven as demons with no chance of ever becoming a god.
After the fall of Adam and Eve, a Savior was promised, and eventually, Elohim came to Israel to have sex with Mary, after which Jesus was born a human and eventually became a god, but not before taking to himself several wives and fathering several children.
If the appeal of occult ideas can be summed up in one word, it is this:
exclusivity. The doctrine that
"I know the path and you don't because you're neither special, worthy, or intelligent...like me" appeals to the basest of all human vanity and is the foundation for paganism, Freemasonry, esoteric catholicism/Judaism/Calvinism, Mormonism, JWs, etc., and every other religion of exclusivity.
