The early apostles and prophets mention numerous sins that were reprehensible to them. Many of them were sexual sins—adultery, being without natural affection, lustfulness, infidelity, incontinence, filthy communications, impurity, inordinate affection, fornication. They included all sexual relations outside marriage—petting, sex perversion, masturbation, and preoccupation with sex in one’s thoughts and talking. Included are every hidden and secret sin and all unholy and impure thoughts and practices. One of the worst of these is incest. The dictionary defines incest as “sexual intercourse between persons so closely related that they are forbidden by law to marry.” The spirituality of one’s life may be severely, and sometimes irreparably, damaged by such an ugly sin. The First Presidency and the Quorum of the Twelve have determined that the penalty for incest shall be excommunication. Also, one excommunicated for incest shall not be baptized again into the Church without the written permission of the First Presidency.
