Post hoc, ergo propter hoc?

I'd like to be able to claim that my parish is growing rapidly because our Pastor is thoroughly orthodox. (He is.) But it could just as easily be that it's growing rapidly because the population in this part of Fairfax County is growing rapidly. The "dying" inner city parishes that have been taken over by thoroughly, explicitly, aggressively orthodox priests better exemplify the point you're making.

The particular parish in the article above has tripled in just a few short months. The surrounding population may be growing, but not nearly at such a rate.

Even in the fastest growing areas of the country, it takes over a decade to even double.
