Tom Baker, Commonweal's publisher (though I'm not quite sure what a publisher actually does) has a review of a book of sermons by Dietrich Bonhoeffer. Baker gives one quote that particularly struck me in this season of endless pontifications about Pope Benedict's resignation, the coming Conclave, and sundry leaks and leakers. Bonhoeffer muses:

Such a struggle carries a great temptation with it: the temptation of being too sure of oneself, of self-righteousness and dogmatism, which also means the temptation to be unloving towards ones opponent.

But then, he was a Protestant hung-up on holiness.
