We were begotten by our Father in heaven; the person of our Father in Heaven was begotten on a previous heavenly world by His Father; and again, He was begotten by still a more ancient Father ….
The Seer by Orson Pratt, p. 132
This is one of those really absurd doctrines of the LDS. Everyone can become a god (as long as they are “temple” Mormons). According to the LDS, everyone on earth, and whoever has ever been on earth, are spiritual siblings begotten of the “god” over this earth. But our LDS god was originally a spirit child of another god on another planet, and ad infinitum. No beginning, just another god as far back as into eternity.
And LDS claims they are Christian?!?! Their “god” is nothing like the God of the Bible, the God not only of Christians but of every human being—not as a spiritual child waiting for a body to inhabit, but born of a man and woman and not existing until such time.
