Chapter 23: Concerning excommunication for faults
If any one is found to be a scorner—being contumacious or disobedient, or a murmurer, or one acting in any way contrary to the holy Rule, and to the precepts of his elders: let such a one, according to the teaching of our Lord, be admonished once, and a second time, secretly, by his elders. If he do not amend his ways, he shall be rebuked publicly in the presence of all. But if, even then, he do not better himself—if he understands how great the penalty is —he shall be subject to excommunication. But, if he is a wicked man, he shall be given over to corporal punishment.
