Someone stole the body!

[Jehanne]

That's the point; II Peter was a forgery.  Do you believe that the Gospel of Peter was written by Peter?

 Peter did not write a Gospel, Peter wrote letters to the churches. None of the letters that Peter wrote that we have today are forgeries.

This is not at all the view of modern scholarship.  Peter was an illiterate peasant who spoke Aramaic; he did not know Greek, and hence, he did not write anything that is part of the historical record.  Few individuals did.  You can repeat a lie a thousand times; it does not change the fact that such is still a falsehood.

However, it amazes me that you can so readily dismiss the Gospel that bears Peter's name.  Who do you think wrote it?
