Marriage Between a Man and Women is Ordained of God

“Marriage is the foundry for social order, the fountain of virtue, and the foundation for eternal exaltation. Marriage has been divinely designated as an eternal and everlasting covenant. Marriage is sanctified when it is cherished and honored in holiness. That union is not merely between husband and wife; it embraces a partnership with God.” -Russell M. Nelson “Nurturing Marriage,” Ensign, May 2006, 36
 
"Marriage is and should be a sacrament. The word sacrament is variously defined, but among Christian people it signifies a religious act or ceremony, solemnized by one having proper authority. It is a pledge, or solemn covenant, a spiritual sign or bond between the contracting parties themselves and between them and God." -Hugh B. Brown

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. -Doctrine & Covenants 49:15

Thou shalt love thy wife with all thy heart, and shalt cleave unto her and none else. -Doctrine & Covenants 49:15
