Yes, but am I?
Yes Alex, you are allowed to express skepticism about this image.
However, it's one thing to be skeptical because the image looks weird, or because you don't see any resemblance to your idea of how Jesus might look, or because there have been so many reports of this sort recently.
It's another thing entirely to object on the basis of principle, the same way the Pharisees pooh-poohed the miracles of Jesus. What I and others are arguing against is the idea that "God couldn't and wouldn't do anything like this....because he simply doesn't "do" this sort of stuff".
That's putting God in a box and it's Pharisee-ism.
