Well, as the Joseph’s mythos goes, we are all Spirit Children of the Mormon God, who
himself was once a man like us but became God and begot us through his many wives.
Now it is said that our Spirit Brother Jesus needed a body to fulfill his purpose, whatever
that is in Mormonism, so the Mormon God came down to have sex with the Virgin Mary.
Keeping in mind about that “Premortal Existence”, that we were all spirit children, uh…
Mormon God
got it on with his spirit daughter, a little disturbing, the LDS has no re-
deeming doctrine behind that, try as they might:
"The fleshly body of Jesus required a Mother as well as a Father. Therefore, the Father and Mother of Jesus, according to the flesh, must have been associated in the capacity of husband and wife; hence the Virgin Mary must have been, for the time being, the lawful wife of God the Father: we use the term lawful wife, because it would be blasphemous in the highest degree to say that He overshadowed her or begat the Savior unlawfully… He had a lawful right to overshadow the Virgin Mary IN THE CAPACITY OF A HUSBAND, and beget a Son…
So there ya go!
