Yes, it is....and that’s why what could otherwise have been a good book is nonsense.
This guy lays out a good case for the authenticity of the Shroud (albeit he plows no new ground), THEN makes one hell of a leap in logic to declare that the disciples’ viewing of His image on the cloth is the entire basis for the resurrection (despite dozens of sightings of Christ post-crucifixion). Frankly, stuff like this just pisses me off.
Without a resurrection (not just viewing an image on a burial cloth), there IS no Christianity.
He is risen indeed!
Remember the story of Doubting Thomas, and how Christ put his doubts to rest? Not an image, but live human flesh!
Luke 24:39 "Look at my hands and my feet. It is I myself! Touch me and see; a ghost does not have flesh and bones, as you see I have."
Luke 24:40 When he had said this, he showed them his hands and feet.
