Red Letter Christians has a post titled “Is This Any Way to Treat a Bible?” which tells how a high school teacher, on seeing a student’s heavily marked Bible, held it up to the class and asked that question. The article that follows is excellent.
I would think a more relevant question would be “Is that any way to treat a student?”
But that aside, I would certainly attract the wrath (and sarcasm) of this teacher. My Greek New Testament is heavily marked, and it’s the replacement for one that I used until it fell apart. I collect Bible editions and many of them have such markings, though none so many as the Greek and Hebrew Bibles I carry with me.
More importantly, I think this displays an inappropriate emphasis on the form. The book is holy as an object, not because of its contents. The marking shows a deep interest in the contents, but the teacher misses that point, and sees only the “desecration” of the object.
Idolatry? Probably too strong a word, but it unfortunately points in that direction.
