Many many years ago I attended a church where they showed a how-to evangelize film in Sunday School. Now this was a respectable, conservative mainline Protestant denomination, not one of those little fly-by-night churches that spring up because someone picked up a Bible and decided to start a new church. So I was quite surprised and appalled to hear the film's narrator explicitly tell people don't waste your time on people who present a challenge by asking hard questions, but instead go after, you guessed it, the vulnerable, the lonely, those who are struggling emotionally, financially, physically. In other words, quantity or quality--we don't want potential C. S. Lewises or St. Augustines or even Martin Luthers here. Not that everyone can or ought to reach that kind of level, but you will never get it if you systematically exclude it. And by the way, speaking as someone who is living on a fixed income, we are pretty tired of being targeted by so-called well-meaning folks who claim to be helping when all they do is exploit us. We have no shortage of would-be exploiters.
