Catena Aurea on Matthew 5:25–26: Augustine of Hippo

Let us see who this adversary is to whom we are bid to be benevolent. It may then be either the Devil, or man, or the flesh, or God, or His commandments. But I do not see how we can be bid be benevolent, or agreeing with the Devil; for where there is good will, there is friendship, and no one will say that friendship should be made with the Devil, or that it is well to agree with him, having once proclaimed war against him when we renounced him; nor ought we to consent with him, with whom had we never consented, we had never come into such circumstances.
