Of course it would be interesting and I hope encouraging to see how many faithful practicing Catholics are out there and if their numbers are increasing. But that being said, do you have any reason to believe the percentage of lapsed, non practicing, or anti Catholics has changed? If anything this has gone DOWN as in the past people were more likely to be “cultural Catholics” who didn’t participate but culture and norms promoted church membership and identification so they went along. Now, again as part of the RCIA team, I see people choosing Catholicism as adults and if my experience is the norm, these are the people who remain faithful practicing Catholics in higher numbers than what I call hit and run Catholics who appear to have their baby baptized and then we never see them again. Given that the percentage of non practicing Catholics has not gone up, wouldn’t we suspect then that more new Catholics (remember not all are baptized as babies, many are not) there would be more practicing Catholics simply by reason of the increased numbers?
Certainly vocations are up, at least in this area vis a vis twenty years ago. Many of our parishes are overflowing and our parish was added to the Archdiocese to take on this increase. I find the news encouraging.
