Monogamy, or restrictions by law to one wife, is no part of the economy of heaven among men. Such a system was commenced by the founders of the Roman Empire... Rome became the mistress of the world, and introduced this order of monogamy wherever her sway was acknowledged.

Brigham YoungWe need to learn, practice, study, know, and understand how angels live with each other. When this community comes to the point to be perfectly honest and upright, you will never find a poor person; none will lack, all will have sufficient.
Brigham YoungAngels are those beings who have been on an earth like this, and have passed through the same ordeals that we are now passing through. They have kept their first estate far enough to preserve themselves in the Priesthood. They did not so violate the law of the Priesthood and condemn themselves to the sin against the Holy Ghost as to be finally lost. They are not crowned with the celestial ones. They are persons who have lived upon an earth, but did not magnify the Priesthood in that high degree that many others have done who have become Gods, even the sons of God.
