Our church is growing by 10 to 12 households per month. And we don't have a Latin Mass!
Probably because you live in a fast growing area. People who live in the fast growing exurbs or in areas with many immigrants who are often Catholic do not get an accurate picture of the health of the church. For example, in many exurbs, even ELCA Lutheran and Epsicopalin churches are being built and have fairly large crowds, but that is hardly indicative of the health of these denominations as a whole.
