“Marriage Is Ordained of God”
Doctrine and Covenants 49:15–17
15 And again, verily I say unto you, that whoso forbiddeth to marry is not ordained of God, for marriage is ordained of God unto man.
16 Wherefore, it is lawful that he should have one wife, and they twain shall be one flesh, and all this that the earth might answer the end of its creation;
17 And that it might be filled with the measure of man, according to his creation before the world was made.
President Joseph Fielding Smith wrote:
“The statement in relation to marriage in section 49 was given to the Church several years before the revelation known as section 132 was revealed. Hence, it is worded as we find it here according to the law of the Church in 1831. This statement in relation to marriage was given to correct the false doctrine of the Shakers that marriage was impure and that a true follower of Jesus Christ must remain in the condition of celibacy to be free from sin and in full fellowship with Christ.
“The people who inhabit this earth were all living in the spirit life before they came to this earth. The Lord informs us that this earth was designed, before its foundations were formed, for the abode of the spirits who kept their first estate, and all such must come here and receive their tabernacles of flesh and bones, and this is according to the number, or measure, of man according to his creation before the world was made. . . . It is the duty of mankind, in lawful and holy wedlock, to multiply according to the commandments given to Adam and Eve and later to Noah, until every spirit appointed to receive a body in this world has had that privilege. Those who teach celibacy and look upon marriage as sinful are in opposition to the word and commandment of the Lord. Such a doctrine is from an evil source and is intended to defeat the plan of redemption and the bringing into the world the spirits who kept their first estate. Satan, in every way that he can and with all his power, endeavors to defeat the work of the Lord. It is his purpose to destroy the souls of men and if he can prevent them from having bodies by teaching men and women that marriage is unrighteous and sinful, or that they should not after they are married bring children into the world, he thinks he will accomplish his purpose. All who hearken to these evil whisperings and practice this evil will stand condemned before the throne of God.”
