“Wait a minute,” Raymond wrote in a comment. “You wrote ‘Like this particular Atheist, I also have reservations about the Shroud’s supernatural implications.’ But on the History Channel you said that you thought the image was formed by a flash of light from the resurrection of Jesus.
No I did not. Watch the show again. Someone else said that. Just because I appeared on the show does not mean that I agree with or echo whatever anyone else said. These shows are patch quilts made up of small clips taken from hours and hours of interviews. Overall the show was great and I agree with most of it.
I don’t know how the image was formed. I’m not going to guess. Having said that I must add that I think there is some good science in support of the idea of a natural amino/carbonyl chemical process. I am open to evidence of a flashed in image. So far, I’ve seen none.
