T. B. H. Stenhouse writes that converts were deceived about LDS theology; God the Father in LDS theology is the same person as Adam.

The confession of faith published by Joseph Smith during his life-time would certainly deceive an uninitiated person; and it was in consequence of the ambiguity of that very document that so many unsuspecting persons were from the beginning of Mormonism led astray by the teachings of the Missionaries. The convert was told that the Mormon faith proclaimed the existence of one true God, but he was not told that Father Adam was the deity, and that He is "like a well-do-do farmer." He was told that Christ was the Son of God, but he was not taught that the Virgin Mary was "the lawful wife of God the Father," and that "He intended after the resurrection to take her again, as one of His own wives, to raise up immortal spirits in eternity. He was told of faith in a Saviour, he was not told that men were the only saviours of their wives, and that unless a woman pleased her husband and was obedient and was saved by him, she could not be saved at all. He was told that the Saints believed in the Holy Ghost, but he was not told that "The Holy Ghost is a man; he is one of the sons of our father and our God . . . You think our Father and God is not a lively, sociable, and cheerful man; He is one of the most lively men that every lived!"
