So, I think you just said that the average Christian does X, but doesn't do X, and therefore I should do X. I can't quite figure out if there's a typo in there somewhere, or whether I'm just misunderstanding radically.

You're right, thanks, the previous wording was confusing. I removed the paragraph that said "I suspect that the average christian actually gives significantly less than 10% of their income to the church, and doesn't go to church every sunday, but I haven't actually looked up the statistics yet." The point of that paragraph was that I'm admitting that I'm probably overestimating the contributions of the average christian.
