It's actually an interesting question. Because the thing is that, IIRC, Bellairs was an extremely devout Catholic. So it wouldn't actually be all that surprising for them to actually have a Christian message, but I can't really recall one. It seems to mostly be in the background, with the characters having a religious life and going to church but without much really explicit religious content.
