Why are people assuming that this is only one hour a week? Cause most church services are longer than that; two hours would be more typical.
Maybe if you're Mormon...a Catholic service is typically 45 minutes to an hour.
Either way, I gotta say no. As a private tutor, I end up working with Jewish clientele most Sunday mornings, and I make at least $100 each Sunday morning/early afternoon as a result. This wouldn't even pay itself off after three years. (Incidentally, I am not rich. Sunday's just a good day for tutoring, or at least it was this year.)
