"When our father Adam came into the garden of Eden, he came into it with a celestial body, and brought Eve, one of his wives with him." Brigham Young, Journal of Discourses, vol. 1, p. 50
Some of the Mormon people believed "that Joseph Smith the Prophet taught that Adam had two wives." Journal of Discourses, vol. 26, p. 115
"Celsus was a heathen philosopher; and what does he say upon the subject of Christ and his Apostles.... He says, "The grand reason why the Gentiles and philosophers of his school persecuted Jesus Christ, was, because he had so many wives; there were Elizabeth, and Mary, and a host of others that followed him. . . .
The grand reason of the burst of public sentiment in anathemas upon Christ and his disciples, causing his crucifixion, was evidently based on polygamy.... A belief in the doctrine of a plurality of wives caused the persecution of Jesus, and his followers. We might almost think they were 'Mormons'." Jedediah M. Grant, second counselor to Brigham Young, Journal of Discourses, vol. 1, pp. 345-46
"It will be borne in mind that once on a time, there was a marriage in Cana of Galilee; ... no less a person than Jesus Christ was married on that occasion. If he was never married, his intimacy with Mary and Martha, and the other Mary also whom Jesus loved, must have been highly unbecoming and improper to say the least of it.
I will venture to say that if Jesus Christ were now to pass through the most pious countries in Christendom with a train of women, such as used to follow him, ... he would be mobbed, tarred, and feathered, and rode not on an ass, but on a rail....
At this doctrine the long-faced hypocrite and the sanctimonious bigot will probably cry, blasphemy! . . . Object not, therefore, too strongly against the marriage of Christ ..." Apostle Orson Hyde, Journal of Discourses, vol. 4, pp. 259-60.
"I discover that some of the Eastern papers represent me as a great blasphemer, because I said, in my lecture on Marriage, at our last Conference, that Jesus Christ was married at Cana of Galilee, that Mary, Martha, and others were his wives, and that he begat children.
All that I have to say in reply to that charge is this—they worship a Savior that is too pure and holy to fulfill the commands of his Father. I worship one that is just pure and holy enough "to fulfill all righteousness;" not only the righteous law of baptism, but the still more righteous and important law "to multiply and replenish the earth." Apostle Orson Hyde, Journal of Discourses, vol. 2, p. 210
"The Scripture says that He, the LORD, came walking in the Temple, with His train; I do not know who they were, unless His wives and children ..." Brigham Young, Journal of Discourses, vol. 13, p. 309.
". . . it will be seen that the great Messiah who was the founder of the Christian religion, was a polygamist, ... the Messiah chose to ... by marrying many honorable wives himself, show to all future generations that he approbated the plurality of wives under the Christian dispensation....
We have now clearly shown that God the Father had a plurality of wives, one or more being in eternity, by whom He begat our spirits as well as the spirit of Jesus His first Born, and another being upon the earth by whom He begat the tabernacle of Jesus, as his only begotten in this world. We have also proved most clearly that the Son followed the example of his Father, and became the great Bridegroom to whom kings' daughters and many honorable wives were to be married. We have also proved that both God the Father and our Lord Jesus Christ inherit their wives in eternity as well as in time; ... it would be so shocking to the modesty of the very pious ladies of Christendom to see Abraham and his wives, Jacob and his wives, Jesus and his honorable wives, all eating occasionally at the same table, ... If you do not want your morals corrupted, and your delicate ears shocked and your pious modesty put to the blush by the society of polygamists and their wives, do not venture near the New Earth; for polygamists will be honored there, and will be among the chief rulers in that Kingdom." Apostle Orson Pratt, The Seer, p. 172
"If none but Gods will be permitted to multiply immortal children, it follows that each God must have one or more wives." Apostle Orson Pratt, The Seer, p. 158
"One of the wives of Brigham Young—Mrs. Augusta Cobb Young ... requested of her Prophet husband a favor of a most extraordinary description. She had forsaken her lawful husband and family ... to join the Saints, ... when the lady of whom I speak asked him to place her at the head of his household, he refused: ... finding that she could not be Brigham's "queen," and having been taught by the highest Mormon authorities that our Savior had, and has, many wives, she requested to be "sealed" to him! Brigham Young told her (for what reason I do not know) that it really was out of his power to do that, but that he would do "the next best thing" for her—he would "seal" her to Joseph Smith. So she was sealed to Joseph Smith, ... in the resurrection she will leave him [Young] and go over to the original Prophet." Author: Fanny Stenhouse, Tell It All, p. 255 See also: Stanley S. Ivins, Joseph Smith and Polygamy, p. 46
"Now, briefly, the reason that the Lord, through the Prophet Joseph, introduced the doctrine of plural marriage, and the reason that the Church ... has never and will never relinquish the doctrine of plural marriage, is simply this: The major purpose of the Church is to help man attain the great eternal destiny suggested in that couplet ...plural marriage is the patriarchal order of marriage lived by God and others who reign in the Celestial Kingdom. As well might the Church relinquish its claim to the Priesthood as the doctrine of plural marriage." John J. Stewart, Brigham Young and His Wives, (1961), p. 41
"Plural marriage was a common practice among God's chosen people.... Mary, Martha, Mary Magdalene and many other women were beloved of Jesus. For a person to say that he believes the Bible but does not believe the doctrine of plural marriage is something akin to saying that he accepts the Constitution but not the Bill of Rights." John J. Stewart, Brigham Young and His Wives, (1961), p. 26
