John Chrysostom
Catena Aurea · Matthäusevangelium 18
Moreover if thy brother shall trespass against thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother. But if he will not hear thee, then take with thee one or two more, that in the mouth of two or three witnesses every word may be established. And if he shall neglect to hear them, tell it unto the Church: but if he neglect to hear the Church, let him be unto thee as an heathen man and a Publican.
And He says not, Accuse him, nor, Chide with him, nor, Demand redress,—but, Tell him of his fault; that is, remind him of his sin, tell him what things you have suffered from him. For he is held down by anger or by shame, stupefied as one in a deep slumber. Wherefore it behoves you who are in your right senses to go to him who is in a disease.
