Actually, though I am a non-believer, religious iconography fascinates me. I struggled to find the exact image of the Slidell Jesus online - the position of his hand was different in the Slidell picture than any others I saw, or the book was closed, or there was no book. Finally, I found the icon for sale on this site, which has a description:
Christ is blessing with His right hand, His fingers formed into the shape of the Greek letters "IC XC", the Greek abbreviation for "Jesus Christ". His blessing hand is turned inward as if to remind us that He is the Great Blessing, granting us an opportunity to repent and inherit eternal life. He is holding a Book of the Gospels in His left arm. It is opened to the passages reading "Judge not according to the appearance, but judge with righteous judgement. (John 7:24) For with what judgement you judge, you shall be judged." (Matthew 7:2)I hear there is a rally tonight on the the Slidell City Court steps. If you are a high school student in attendence, be careful what you say.
Christ is traditionally shown with a short beard and long dark hair parted in the middle. His expression is serious, but not without mercy. Christ's outer robe is blue, to symbolize His humanity which he put on in His Incarnation, and His inner robe is red, to represent His divinity that He always was in eternity.
Christ Our God is the Saviour of all men who would be saved and who acknowledge their sinfulness, their need to be saved in truth by their own cooperation, and thus truly repent "for the Kingdom of Heaven is at hand!"
