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 you as a heathen man and a tax collector.
All Commentaries on Matthew 18:17 Go To Matthew 18
Augustine of Hippo
AD 430
But “if he does not listen,” that is, if he chooses to justify his sin as if it were a just action, “take one or two others along with you, that every word may be confirmed by the evidence of two or three witnesses. If he refuses to listen to them, tell it to the church; and if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.” Don’t consider him now in the number of your brothers. But not even so is his salvation to be neglected. For even the heathen, that is, the Gentiles and pagans, we do not consider in the number of our brothers, yet we constantly pray for their salvation.
