They're starting an official investigation into the sudden, presumably miraculous, healing of a French nun who was delivered from Parkinson's disease through the intercession of the late John Paul the Great. Even while he was alive there were always rumors swirling around about JPG's healing powers, and after his death such stories have flooded into the Vatican. The Vatican's pretty cautious about such things. I had to laugh at soon-to-be-Cardinal Dziwisz's explanation of how the Vatican chose to investigate this alleged miracle first:
Ha!
He speculated, in an interview with the Roman news agency I Media, that the French case had been selected for a thorough investigation in part because France is "a country from which this was not expected."
