We believe that all religious societies have a right to deal with their members for disorderly conduct, according to the rules and regulations of such societies; provided that such dealings be for fellowship and good standing; but we do not believe that any religious society has authority to try men on the right of property or life, to take from them this world’s goods, or to put them in jeopardy of either life or limb, or to inflict any physical punishment upon them. They can only excommunicate them from their society, and withdraw from them their fellowship.
D&C 42:90-93: Why are some discipline matters announced publicly?
And if thy brother or sister offend many, he or she shall be chastened before many. And if any one offend openly, he or she shall be rebuked openly, that he or she may be ashamed. And if he or she confess not, he or she shall be delivered up unto the law of God. If any shall offend in secret, he or she shall be rebuked in secret, that he or she may have opportunity to confess in secret to him or her whom he or she has offended, and to God, that the church may not speak reproachfully of him or her. And thus shall ye conduct in all things.

Wherefore, let every man beware lest he do that which is not in truth and righteousness before me.
Behold, the Lord requireth the heart and a willing mind; and the willing and obedient shall eat the good of the land of Zion in these last days. And the rebellious shall be cut off out of the land of Zion, and shall be sent away, and shall not inherit the land.
And they who are of the High Priesthood, whose names are not found written in the book of the law, or that are found to have apostatized, or to have been cut off from the church, as well as the lesser priesthood, or the members, in that day shall not find an inheritance among the saints of the Most High;
