Has anyone read the Didache series. It is a Catholic series that has 4 volumes? I have the History of the Church book and it is really the best history book regarding the church I have ever read. I have taken a graduate course in church history and this edition blows away what I learned in class. I will be getting the volume called, Understanding the Scriptures written by Scott Hahn and look forward to seeing how this compares with scripture courses I have taken.
