The law of chastity is a moral code defined by the Church of Jesus Christ of Latter-day Saints (LDS Church). According to the church, chastity means that "sexual relations are proper only between a man and a woman who are legally and lawfully wedded as husband and wife." Therefore, abstinence from sexual relations outside of marriage, and complete fidelity to one's spouse during marriage, are required. As part of the law of chastity, the church teaches its members to abstain from adultery and fornication.
