2000 Years of Christ's Power Vol 2: The Middle Ages

These volumes represent expert historical scholarship in a very readable form. Biographical sketches of all significant people, and their doctrinal positions, are interspersed with the record of great movements and debates. A massive amount of interesting information is available here. Surely there is nothing quite as convenient or reliable from an evangelical standpoint. Whether read or dipped into for reference this is a very precious resource for all.
