Second paragraph above: Pope it is claimed would like to see it. Your right it does/could be just a rumor with the "it is claimed" part.
Clearly it is just a rumor. Also, there’s no reason why the pope or some other scholar - yes, Christians ones - wouldn’t want to see this. It’s in Aramaic. It’s old (how old no one knows yet). And it’s a forgery. Scholars like to look at interesting things and this is interesting.
