The ordinance of sealing must be performed here man to man, and woman to man, and children to parents, etc., until the chain of generation is made perfect in the sealing ordinances back to father Adam; hence, we have been commanded to gather ourselves together, to come out from Babylon, and sanctify ourselves, and build up the Zion of our God, by building cities and temples, redeeming countries from the solitude of nature, until the earth is sanctified and prepared for the residence of God and angels.

– Brigham Young, 2/16/1868
