Athanasius and Gregory: Incarnation as Purification

"Atonement" is a word invented for the translation of the Bible into English, because there was no good English word for the concept it describes. So what does it mean? People have atonement theories. Is atonement purely theoretical? Does it have anything to do with suffering or punishment? And who or what is atoned for? Fr. Stephen De Young and Fr. Andrew Stephen Damick finish their three-part series on sacrifice.
