All religious books and relics are of questionable authenticity, or downright fakes. And religions often prevent any test that would prove or disprove whether they are fakes or forgeries.
This “new” bible seems to agree with the Koran that Jesus was not God but merely a prophet. But no scientist is allowed by Islamics to test its age and authenticity.
Similarly, the Catholic Church would not let the shroud of Turin, supposedly the burial cloth of Jesus, be tested for hundreds of years. When it was tested, it showed that it was created a thousand years after the death of Jesus. Then religious people claimed that a section of the shroud that was tested was a patch, even though great care was taken by the scientists to test the original fabric. This relic is a fake, and other books and relics are all fakes also.
