Members of the Church found guilty of child abuse are also subject to the laws of God. President Hinckley has said: "Our hearts reach out to the offender, but we cannot tolerate the sin of which he may be guilty. Where there has been offense, there is a penalty." Convicted child abusers are excommunicated, the highest possible discipline our faith can impose. Excommunicated members cannot take part in Church meetings or hold responsibilities of any kind within the congregation.
Because I know some dimwit will say that child abuse is an accepted practice in the LDS Church.
Just like Mountain Meadows or polygamy.
