'Is Christianity Good for the World?'

Christian theologian Douglas Wilson and atheist Christopher Hitchens are debating that question at ChristianityToday.com. Here's a snippet:

Hitchens: if (sic) Christianity is to claim credit for the work of outstanding Christians or for the labors of famous charities, then it must in all honesty accept responsibility for the opposite. I shall not condescend to your readers in specifying what these "opposites" are, but I suggest once more that you pay attention to the Golden Rule. If hymns and psalms were sung to sanctify slavery—just to take a recent example—and then sung by abolitionists, then surely the non-fanatical explanation is that morality requires no supernatural sanction? Every Christian church has had to make some apology for its role in the Crusades, slavery, anti-Semitism, and much else. I do not think that such humility discredits faith as such, because I tend to think that faith is a problem to begin with, but I do think that humility will lead to the necessary conclusion that religion is man-made.

Wilson: In short, if we point to our saints, you are going to demand that we point also to our charlatans, persecutors, shysters, slave-traders, inquisitors, hucksters, televangelists, and so on. Now allow me the privilege of pointing out the structure of your argument here. If a professor takes credit for the student who mastered the material, aced his finals, and went on to a career that was a benefit to himself and the university he graduated from, the professor must (fairness dictates) be upbraided for the dope-smoking slacker that he kicked out of class in the second week. They were both formally enrolled, is that not correct? They were both students, were they not?

What you are doing is saying that Christianity must be judged not only on the basis of those who believe the gospel in truth and live accordingly but also on the basis of those baptized Christians who cannot listen to the Sermon on the Mount without a horse laugh and a life to match. You are saying that those who excel in the course and those who flunk out of it are all the same. This seems to me to be a curious way of proceeding.
