Interesting to see what forensics makes of the Shroud and Sudarium, and in time we'll have the ability to clone Jesus or whomever those DNA strands belong to. (Not that we should, but in the brave new world, we probably will.) Of course, it's all about faith. God looks like all of us. Or the reverse...each and every one of us was made in the image of God.
There is already a novel out about this, where someone "Jurrasic-Park"-like found a drop of Jesus' blood in a piece of wood and recreated the DNA.
