Here's a fabulous link to all the cannonized and uncannonized books and other writings of old. I personally love this site. Dig around, it is interesting. Anyone wanting to look up Enoch and the books of Thomas and the like will find this site interesting. In your case go to the Early Church Doctrines and see if that helps you to find what you might be looking for. Links that talk abut Bible Study mean Studies of the Bible so don't get confused at that.
