Brigham Young preached, "The only men who become Gods, even the Sons of God, are those who enter into polygamy" (Journal of Discourses (JOD) 11:269).
On October 12, 1856, Heber C. Kimball (first counselor to Brigham Young) declared, "You might as well deny 'Mormonism,' and turn away from it, as to oppose the plurality of wives." (JOD 5:203).
In 1866, Brigham Young forcefully stated, "We are told that if we would give up polygamy--which we know to be a doctrine revealed from heaven and it is God and the world for it--but suppose this Church should give up this holy order of marriage, then would the devil, and all who are in league with him against the cause of God, rejoice that they had prevailed upon the Saints to refuse to obey one of the revelations and commandments of God to them." Later in the sermon President Young asked, "Will the Latter-day Saints do this? No" (JOD 11:239).
That same year, John Taylor, Mormonism's future third president, accused those who opposed polygamy within the LDS Church as "apostates." He said: "Where did this commandment come from in relation to polygamy? It also came from God...When this commandment was given, it was so far religious, and so far binding upon the Elders of this Church that it was told them if they were not prepared to enter into it, and to stem the torrent of opposition that would come in consequence of it, the keys of the kingdom would be taken from them. When I see any of our people, men or women, opposing a principle of this kind, I have years ago set them down as on the high road to apostacy, and I do to-day; I consider them apostates, and not interested in this Church and kingdom" (JOD 11:221).
In 1869 Wilford Woodruff, Mormonism's future fourth president, taught, "If we were to do away with polygamy, it would only be one feather in the bird, one ordinance in the Church and kingdom. Do away with that, then we must do away with prophets and Apostles, with revelation and the gifts and graces of the Gospel, and finally give up our religion altogether and turn sectarians and do as the world does, then all would be right. We just can't do that, for God has commanded us to build up His kingdom and to bear our testimony to the nations of the earth, and we are going to do it, come life or come death. He has told us to do thus, and we shall obey Him in days to come as we have in days past" (JOD 13:165 - p.166).
Even as late as 1879, Joseph F. Smith was insisting that plural marriage was essential for LDS exaltation. Speaking at the funeral of William Clayton, Mormonism's future sixth president, stated, "This doctrine of eternal union of husband and wife, and of plural marriage, is one of the most important doctrines ever revealed to man in any age of the world. Without it man would come to a full stop; without it we never could be exalted to associate with and become god..." (JOD 21:9).
During a message given in 1880, Mormon Apostle Orson Pratt said, "...if plurality of marriage is not true or in other words, if a man has no divine right to marry two wives or more in this world, then marriage for eternity is not true, and your faith is all vain, and all the sealing ordinances, and powers, pertaining to marriages for eternity are vain, worthless, good for nothing; for as sure as one is true the other also must be true." (JOD 21:296).
In today's world of Mormonism, Joseph Smith, Brigham Young, Orson Pratt, John Taylor, and many other well-known heroes of the Mormon faith would be promptly excommunicated from the LDS Church for their participation in practicing their view of celestial marriage. LDS Apostle Bruce McConkie declared, "All who pretend or assume to engage in plural marriage in this day, when the one holding the keys has withdrawn the power by which they are performed, are guilty of gross wickedness" (Mormon Doctrine, pp.579). No doubt, if Brigham Young were alive, he would rebut this by stating, "Now if any of you will deny the plurality of wives, and continue to do so, I promise that you will be dammed..." (Journal of Discourses 3:266).
Now we read about Black skinned people.
Smith also stated that "there is a reason why one man is born black and with other disadvantages, while another is born white with great advantages. The reason is that we once had an estate before we came here, and were obedient; more or less, to the laws that were given us there. Those who were faithful in all things there received greater blessings here, and those who were not faithful received less" (Doctrines of Salvation 1:61).
For these reasons, Bruce McConkie would write, "The negroes are not equal with other races where the receipt of certain spiritual blessings are concerned, particularly the priesthood and the temple blessings that flow therefrom…" (Mormon Doctrine, p.527, 1966 ed.).
In a sermon given on March 8, 1863, Young stated, "Shall I tell you the law of God in regard to the African race? If the white man who belongs to the chosen seed mixes his blood with the seed of Cain, the penalty, under the law of God, is death on the spot. This will always be so" (Journal of Discourses, 10:110).
On two separate occasions, third LDS President John Taylor stated that it was God's plan to allow the seed of Cain to remain on the earth in order for the devil to be properly represented. On August 28, 1881, he declared, "And after the flood we are told that the curse that had been pronounced upon Cain was continued through Ham's wife, as he had married a wife of that seed. And why did it pass through the flood? Because it was necessary that the devil should have a representation upon the earth as well as God" (Journal of Discourses 22:304).
The following year, Taylor reiterated his former comment when he said, "Why is it, in fact, that we should have a devil? Why did the Lord not kill him long ago? Because he could not do without him. He needed the devil and a great many of those who do his bidding to keep men straight, that we may learn to place our dependence on God, and trust in Him, and to observe his laws and keep his commandments. When he destroyed the inhabitants of the antediluvian world, he suffered a descendant of Cain to come through the flood in order that he might be properly represented upon the earth" (Journal of Discourses 23:336).
On December 3, 1854, Brigham Young said, "When all the other children of Adam have had the privilege of receiving the Priesthood, and of coming into the kingdom of God, and of being redeemed from the four quarters of the earth, and have received their resurrection from the dead, then it will be time enough to remove the curse from Cain and his posterity" (Journal of Discourses 2:143).
President Wilford Woodruff noted in his journal that President Young said, "...that mark shall remain upon the seed of Cain until the seed of Abel shall be redeemed, and Cain shall not receive the Priesthood, until the time of that redemption" (History of Wilford Woodruff, p.351, as printed in The Way to Perfection, p.106).
