§14. A portrait once effaced must be restored from the original. Thus the Son of the Father came to seek, save, and regenerate. No other way was possible. Blinded himself, man could not see to heal. The witness of creation had failed to preserve him, and could not bring him back. The Word alone could do so. But how? Only by revealing Himself as Man.
For as, when the likeness painted on a panel has been effaced by stains from without, he whose likeness it is must needs come once more to enable the portrait to be renewed on the same wood: for, for the sake of his picture, even the mere wood on which it is painted is not thrown away, but the outline is renewed upon it; 2. in the same way also the most holy Son of the Father, being the Image of the Father, came to our region to renew man once made in His likeness, and find him, as one lost, by the remission of sins; as He says Himself in the Gospels: “I came 238 to find and to save the lost.” Whence He said to the Jews also: “Except 239 a man be born again,” not meaning, p. 44 as they thought, birth from woman, but speaking of the soul born and created anew in the likeness of Gods image. 3. But since wild idolatry and godlessness occupied the world, and the knowledge of God was hid, whose part was it to teach the world concerning the Father? Mans, might one say? But it was not in mans power to penetrate everywhere beneath the sun; for neither had they the physical strength to run so far, nor would they be able to claim credence in this matter, nor were they sufficient by themselves to withstand the deceit and impositions of evil spirits. 4. For where all were smitten and confused in soul from demoniacal deceit, and the vanity of idols, how was it possible for them to win over mans soul and mans mind—whereas they cannot even see them? Or how can a man convert what he does not see? 5. But perhaps one might say creation was enough; but if creation were enough, these great evils would never have come to pass. For creation was there already, and all the same, men were grovelling in the same error concerning God. 6. Who, then, was needed, save the Word of God, that sees both soul and mind, and that gives movement to all things in creation, and by them makes known the Father? For He who by His own Providence and ordering of all things was teaching men concerning the Father, He it was that could renew this same teaching as well. 7. How, then, could this have been done? Perhaps one might say, that the same means were open as before, for Him to shew forth the truth about the Father once more by means of the work of creation. But this was no longer a sure means. Quite the contrary; for men missed seeing this before, and have turned their eyes no longer upward but downward. 8. Whence, naturally, willing to profit men, He sojourns here as man, taking to Himself a body like the others, and from things of earth, that is by the works of His body [He teaches them], so that they who would not know Him from His Providence and rule over all things, may even from the works done by His actual body know the Word of God which is in the body, and through Him the Father.
