In these respects we differ from the Christian world, for our religion will not clash with or contradict the facts of science in any particular... whether the Lord found the earth empty and void, whether he made it out of nothing or out of the rude elements; or whether he made it in six days or in as many millions of years, is and will remain a matter of speculation in the minds of men unless he give revelation on the subject. If we understood the process of creation there would be no mystery about it, it would be all reasonable and plain, for there is no mystery except to the ignorant.
Brigham YoungMonogamy, 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. Thus this monogamic order of marriage, so esteemed by modern Christians as a hold sacrament and divine institution, is nothing but a system established by a set of robbers.
