Athanasius in “On the Incarnation”, roughly 376 A.D.:
You know what happens when a portrait that has been painted on a panel becomes obliterated through external stains? The artist does not throw away the panel, but the subject of the portrait has to come and sit for it again, and then the likeness is re-drawn on the same material. Even so was it with the All-holy Son of God. He, the Image of the Father, came and dwelt in our midst, in order that He might renew mankind made after Himself, and seek out His lost sheep, even as He says in the Gospel: ‘I came to seek and to save that which was lost.’
Which calls to mind a verse of Charles Wesley’s great hymn, “Hark the Herald Angels Sing” which I’ve heard rarely sung:
Adam’s likeness, Lord, efface,
Stamp Thine image in its place:
Second Adam from above,
Reinstate us in Thy love.
Let us Thee, though lost, regain,
Thee, the Life, the inner man:
O, to all Thyself impart,
Formed in each believing heart.
