Totally agree. I'm an agnostic and I love both history and civics. Some very vocal atheists out there are keen to attack Christianity at every turn, including the Bible itself. If you want to understand our place in the world, you have to understand the major religions - Christianity and Islam included. Trying to describe our world without that is like trying to describe the circulatory system without mentioning the heart. 

More to the point, the Bible isn't bad literature. Parts of it are hard for modern readers to engage but that's true of so much important literature that it's a silly point to make. Ever try to read Beowulf? Milton? Rousseau? Homer? Cicero? It's rewarding to do so if one is so inclined, but it doesn't jump off the page like a Stephen King novel.
