Treatment of Transgressors in the Church
Moroni 6:7–8
7 And they were strict to observe that there should be no iniquity among them; and whoso was found to commit iniquity, and three witnesses of the church did condemn them before the elders, and if they repented not, and confessed not, their names were blotted out, and they were not numbered among the people of Christ.
8 But as oft as they repented and sought forgiveness, with real intent, they were forgiven.
President James E. Faust said:
“Church discipline is not limited to sexual sins but includes other acts such as murder, abortions, burglary, theft, fraud, and other dishonesty, deliberate disobedience to the rules and regulations of the Church, advocating or practicing polygamy, apostasy, or any other unchristianlike conduct, including defiance or ridicule of the Lord’s anointed, contrary to the law of the Lord and the order of the Church. . . .
“Among the activities considered apostate to the Church include when members ‘(1) repeatedly act in clear, open, and deliberate public opposition to the Church or its leaders; (2) persist in teaching as Church doctrine information that is not Church doctrine after being corrected by their bishops or higher authority; or (3) continue to follow the teachings of apostate cults (such as those that advocate plural marriage) after being corrected by their bishops or higher authority’ (General Handbook of Instructions, 1989, p. 10-3).”
