“If He Repent Not He Shall Not Be Numbered Among My People, That He May Not Destroy My People”

Joseph F. McConkie, Robert L. Millet
Transgressors who will not repent or who pose a serious threat, physical or spiritual, to the Church are “cut off from the Church”-meaning excommunicated (see Mosiah 26:31-32; Alma 1:24; Mosiah 5:57-58; Mosiah 6:3-6; Moroni 6:7; D&C 20:83). Church discipline is not only intended to help the sinner repent and return to the Lord but also is a means of protecting members and safeguarding the integrity and spiritual values of the Church.
