Paul Evdokimov in The Art of the Icon
“Kalokagathic” – what a wonderful word! It’s is a Greek coinage, combining the word for beautiful(kalos) and the word for good (agathos). To see an icon is so very far removed from viewing an art object. First off, an icon is never an object. Faces in an icon are never in profile, but look at us face to face. To rightly see an icon is to see it in relationship, that is, to see it personally. And the person whom we see is not the wood and paint, but the one whom the image on the wood and paint represents. It is this encounter that makes it possible to speak of an iconographic proof of the existence of God. I know there is a God because I have seen His image.
In the most perfect sense of this understanding, Christ is the proof of the Father’s existence, because He is the “image of the invisible God” (Col. 1:15). Thus Christ is the visible of the invisible. “If you have seen me, you have seen the Father,” (John 14:9).
It is also true that man is created in the image and likeness of God – though only in Christ, the perfect man (and perfect God), is the image and likeness truly realized. But Christ Himself extends the image – gathering into Himself, “the least of these my brethren” (Matthew 25:40). Thus every human being offers the opportunity of an encounter with God – if we have the eyes to see. Every human being is proof, poor though it may be, of the existence of God.
Pavel Florensky in his wonderful book Iconostasis, says that “Rublev’s icon of the Holy Trinity exists, therefore God exists.” The first time I read the statement I was brought up short. It took time to see what he meant and to see that it was true. A couple of years later one of my daughters was visiting Moscow. She sent a postcard say, “I have seen Rublev’s Trinity. It’s true.” What a marvelous witness!
