Just screencapped this. Look at the number of notes.
That's pretty cool. I'd like to know what phenomenon is responsible for this. (Although my cynical side suspects wax and/or taxidermy of some sort.)
Skeptics figure wax. A big part of this was the exhumation and autopsy of Saint Bernadette, where they found her body "uncorrupted" and her organs still soft and fleshy. Her skin is actually browned beneath a waxy coating, indicating that circumstances are simply leading to her rotting (or appearing to rot) slower than normal. A fascist cardinal who was a friend of Mussolini, Cardinal Shuster, was found uncorrupted 31 years after his death. People like this led to the discontinuation of the practice of using uncorrupted bodies as a prerequisite for sainthood.
Generally the Catholic Church doesn't care about their saints being uncorrupted as much as they do uncorrupted bodies that aren't indicative of saints...
