OP maintains that plural marriage is required for salvation.
Orson Pratt, "Celestial Marriage," The Seer, 1, no. 11 (Washington, D.C.: Orson Pratt, 1853-54), 172
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 . . .
. . . And then 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, and visiting one another, and conversing about their numerous children and their kingdoms. Oh, ye delicate ladies of Christendom, how can you endure such a scene as this? . . . 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 holy Jerusalem, nor come near the New Earth; for Polygamists will be honored there, and will be among the chief rulers in that Kingdom.
