It is pretty easy to see why Pope John Paul II is on the way to sainthood, especially if you are a reasonably faithful Catholic.
The article that piqued my interest today is about the beatification process, the first step in declaring a saint. The BBC article talks about a French nun who claims to have been cured of Parkinson's after praying to the deceased Pope. Ok. No problem. This is the thing that caught my attention:
"Information for the dossier was gathered on the former Pope's life and teachings, including all private writings from the period before he became Pope, and checked for orthodoxy to ensure that he expressed no heretical views."
So, it could be possible that he caused a miracle (or more) even if he were a heretic? That doesn't make any logical sense to me (leaving aside whether or not miracles make any logical sense). If the man were a heretic, and heretics were evil/bad, then why would God let him cause a miracle? God wouldn't, right? So then, if she prayed to JPII and god a miracle, it should stand to reason that he wasn't a heretic.
