The whole thing is rather strange. I assume that there are many Catholics self aware enough to know that he clearly didn't perform any miracles but just go along with it anyway.
This is just how it's always worked. It was just easier to convince people to believe in miracles when we didn't have explanations for everything and video cameras. The church is reaching for coincidences and calling them miracles because that's the best they can do. I'm just surprised they are still trying to make saints and not just settling for Saint Classic.
