The mysterious Shroud of Turin continues to captivate secular scientists and historians as much as it does Christian believers. Is it an authentic 2000-year-old Jerusalem "selfie" of Jesus Christ proving the Resurrection? Or is it an elaborate medieval forgery which the best forensic scientists in the world and all of their instruments still cannot even begin to explain?
