You may be right--but I am still a little skeptical. Assuming that your numbers are accurate, the church has almost quintupled in size since 1930. That was the year that the world's population hit an estimated two billion (and it is now in excess of eight billion). So the growth of the church has at least kept pace with global population growth--and perhaps exceeded it a bit.

But a couple of questions linger. Are affiliation numbers accurate--that is, are the people leaving through the back door (the 20-somethings who have stopped coming to mass and simply drifted away) being counted? That doesn't appear to be an issue in your parish--but it has been elsewhere. The second question is about engagement ... in some cases, traditional religions are maintaining their numbers--but their influence over their congregants has ebbed considerably, and lay participation has become much more sporadic.

Personally, I agree that we are by nature religious animals ... but I suspect that the religion(s) of the future are going to look quite different from the churches, synagogues and mosques that dot our landscape today.
