Once we know how observant a person is in terms of church attendance, nothing that we can discover about the content of her religious faith adds anything to our understanding or prediction of her good neighborliness...In fact, the statistics suggest that even an atheist who happened to become involved in the social life of the congregation (perhaps through a spouse) is much more likely to volunteer in a soup kitchen than the most fervent believer who prays alone. It is religious belongingness that matters for neighborliness, not religious believing.
