The resolution source for this market will be a consensus of credible sources.

I'm too skeptical to believe that a source is credible if that source claims any resurrection, let alone of a messiah. If a man who looks just like Jesus in the images showed up and performed all of the same miracles, I still wouldn't believe it. I wouldn't believe it if the Pope declared it true, or something claiming to be God announced it into my ear.

At the very least they should name the credible sources in advance, because the bet is on their credulity.
