I have to admit that I agree with him. The bible is, after all, a book, and a ban on studying a book amounts to censorship. What is more, the text has some anti-capitalist and anti-bigotry threads, such as the Jesus guy kicking out the money lenders out of the temple and saying that rich men would not go to heaven (whatever that is), challenging those who are without sin to cast a stone, or encouraging to love thy enemies.
In my youth, I entered a church armed with a copy of the bible and approached a nun who was sitting at a counter selling various religious paraphernalia. I showed her the passage where the protagonist (Jesus) kicks out merchants out of the temple and asked her how that squared with the mercantile practices she was conducting in the church. Well, that time it was me who got kicked out from that church and the selling nun shouting "go away you satan." So the book itself can be used for a good purpose, just as any other literary material. If I was in that HS, I would love to join the bible club and point out the inconsistencies between what that book says and what the christians practice.
