It gets worse than that. Mormons have also taught salvation comes through Joseph Smith, Smith has been elevated to god.
"Come on! ye prosecutors! ye false swearers! All hell, boil over! Ye burning mountains, roll down your lava! for I will come out on top at last. I have more to boast of than ever any man had. I am the only man that has ever been able to keep a whole church together since the days of Adam. A large majority of the whole have stood by me. Neither Paul, John, Peter, nor Jesus ever did it. I boast that no man ever did such a work as I. The followers of Jesus ran away from Him; but the Latter-day Saints never ran away from me yet...When they can get rid of me, the devil will also go." (Joseph Smith, History of the Church, Vol. 6, p. 408, 409)
. . . no man or woman in this dispensation will ever enter into the celestial kingdom of God without the consent of Joseph Smith. . . . Every man and woman must have the certificate of Joseph Smith, junior, as a passport to their entrance into the mansion where God and Christ are . . . I cannot go there without his consent. . . . He reigns there as supreme a being in his sphere, capacity, and calling, as God does in heaven (Brigham Young, Journal of Discourses, vol. 7, p. 289).
I will now give my scripture—"Whosoever confesseth that Joseph Smith was sent of God . . . that spirit is of God; and every spirit that does not confess that God has sent Joseph Smith, and revealed the everlasting Gospel to and through him, is of Anti-christ . . . (Brigham Young, Journal of Discourses, vol. 8, p. 176 ).
Truer words were never spoken.
You are so Obama...
