Tertullian On Modesty If we confess our sins, faithful and just is He to remit them to us, and utterly purify us from every unrighteousness."[243] Cyprian Treatise VIII On Works and Alms And again, in his epistle, John lays it down, and says, "If we say that we have no sin, we deceive ourselves, and the truth is not in us."[10] Cyprian Treatise XII Three Books of Testimonies Against the Jews Also in the Epistle of John: "If we say that we have no sin, we deceive ourselves, and the truth is not in us."[644] Gregory Thaumaturgus A Metaphrase of the Book of Ecclesiastes Wisdom availeth more in the way of help than a band of the most powerful men in a city, and it often also pardons righteously those who fail in duty. For there is not one that stumbleth not.[50] Genuine Acts of Peter of Alexandria and another, "If we say we have no sin, we deceive ourselves, and the truth is not in us."[40]
