This is something I have been thinking about ever since I posted on St John Cantius in Chicago, and St Peter's in Omaha. I have repeatedly watched the videos I linked to there. One thing that has struck me is that they they say that anyone can do what they have done, in a sort of "if you build it, they will come" way. They also speak of how people come to them and talk about how much better the way Mass is done at these places than it was at their old church. That's one of the things I have been pondering.
A few weeks back there was an article (can't find the link now, saw it on other blogs.) about nuns, where one "expert" said that returning to the old habits will not necessarily mean more nuns, everywhere, just the same number of nuns spread out, as the number of women who wish to get into that sort of thing is a very "small pool."
Most conservative Catholics derided these comments, but I wonder. Is there something to what the expert has said? Are these communities bringing people back, or are they bringing in people already so inclined? Are churches like Cantius and St. Peter's filling their churches by bringing people back, or by bringing them over from other parishes, filling their pews by emptying another's?
