Yes, the plural of Bible is Bibles (although “bible” in itself comes from the Greek word for “books”, which is a plural already). But the way of developing the plural of Bibles is apparently being a Christian for a long time.
I recently finished reading The Imitation of Christ by Thomas à Kempis. I read it slowly, because was my bathroom book (sorry if that’s too much information, but it’s a great way to read important but not terribly gripping books) but also because it just wasn’t very good.
