A Messianic Jewish friend of mine and I were talking about icons. He has a big problem with them. I told him that the Jews were forbidden to make an image of God because no one knew what He looked like. Since God became flesh in Jesus Christ, we know exactly what He looks like, as Jesus is the image of God and the exact representation of His being. I asked him, "Do you think that of the thousands of people that saw Him, not one person drew or painted His picture?" His response was surprising since I consider him an intelligent and articulate individual. He said, "Don't be so sure of it."
But, for the sake of argument, let's say he is right. Supposing no one ever painted a picture of the actual Jesus, does this mean that His image is still not captured in the icon? People who knew Jesus well didn't recognize him after His resurrection until the Lord decided to "reveal" Himself by breaking bread. People who feed the hungry, clothe the naked, give drink to the thirsty and visit the sick also don't recognize Jesus either. Does this mean His image is not in the world? Does the mean we have no point of reference to the God-man, the one made flesh for all to behold?
I think the truth of the matter lies in the icon image itself. It shows this man to be the Word of God, the Great I Am, the Almighty, the one who was humiliated, crucified, risen and ascended. The one who blesses and teaches us. He is our healer, our portion and our cup, the One Who Is and Who Was and Who is to come. My friend would certainly never deny these truths about Christ, and yet, despite any particular artistic detail regarding the accuracy of His physical features, the icons proclaim all of these realities and more - the Spirit of Truth rests upon them.
The same can be said for all of the other icons - they represent the truth of the Faith and the reality of the Kingdom of God, of a life that never ends, and of the living stones that make up the heavenly temple. It has been said so well before by many others, but Paul says it best when he says in the book of Hebrews that we have come to the heavenly Jerusalem, to the spirits of righteous men made perfect. Our icons help us keep this focus - on things above and not on the things of the earth.
