How do they know it is an image of Jesus? Where in scripture does it give a detailed enough description of His appearance that one could know an image is His image?
The reality is, they don't know what He looks like. They want to see an image of Jesus, and so anything they can imagine looking like an image of a guy with long hair and a beard is said to be an image of Christ.
... and I have to wonder how this “skeptic” supposedly got close enough and still enough to capture this photo.
My Roman Catholic friends: Jesus can be found. But not in a wafer.
