Yes, I suppose that if you wanted to be really very picky, you could argue that the word 'crusade' would be better suited than 'campaign' for denoting a religious service, and I would not disagree with that. I might even have been persuaded to use that word instead if anyone had suggested that, but I do not remember anyone saying anything about that, or at least relaying the message to me, because there was an editor who reviewed the entire book later, so who knows what else they did with that later.
And also I remember the demons berating us for singing "Onward Christian Soldiers," so I don't know, maybe I do not have a firm opinion on that either way.
