" repentance recall men from what is according to their nature; all that it does is to make them cease from sinning. Had it been a case of a trespass only, and not of a subsequent corruption, repentance would have been well enough; but when once transgression had begun men came under the power of the corruption proper to their nature and were bereft of the grace which belonged to them as creatures in the Image of God. "

― Athanasius of Alexandria , On the Incarnation
