“Marriage according to the law of the Church is the most holy and sacred ordinance. It will bring to the husband and wife, if they abide in their covenants, the fullness of exaltation in the Kingdom of God. When that covenant is broken, it will bring eternal misery to the guilty party, for we will all have to answer for our deeds done while in the flesh. It is an ordinance that cannot be trifled with, and the covenants made in the temple cannot be broken without dire punishment to the one who is guilty.”
Joseph Fielding Smith, Doctrines of Salvation – Volume 2 (Salt Lake City, UT: Bookcraft, Inc., 1955), 84.
