It seems rather curious that muslims would keep this bible under wraps. Wouldn't it be proof against islam and mohammeds haters and disbelievers that jesus did speak of the coming messiah and named him mohammed? If I were muslim I would get this out there with as much media attention as possible...so why keep it out of the public eye for 12 years?
I'm thinking it's like the early bible schoalrs and Big Heads. They kept the bible untranslated and out of the commoners hands so they could control the message...once it was translated and in the hands of the public...people could decide for themselves whether it was authentic and worth believing in.
