Although there is no clear record of Joseph Smith teaching of Heavenly Mother publicly, several of Smith's contemporaries attributed the theology to him either directly, or as a consequence of his theological stance.
Tradition again!
An editorial footnote of History of the Church, 5:254, presumably quotes Joseph Smith as saying: "Come to me; here's the mysteries man hath not seen, Here's our Father in heaven, and Mother, the Queen."
According to one sermon by Brigham Young, Joseph Smith once said he "would not worship a God who had not a father; and I do not know that he would if he had not a mother; the one would be as absurd as the other."[11]
Finally, the real ontological mother of God has been found! Blasphemous!
Damned HISTORY!!
It'll be the DEATH of us all!
