Michael Gerson, True Christian

Even though, by my capacious standards, he's Jewish. But that's another story. Here he is on the scandal of the Holocaust-denying bishop:

It is very difficult to understand how those who worship a man on a cross could help to drive the bloody nails themselves. But the record is clear: When religion is infected by racism, ideology or extreme nationalism, it can become a carrier of hatred instead of conscience. And when churches are concerned mainly with their institutional self-preservation, they often end up neck-deep in compromise or paralyzed by cowardice.
