A good introductory text, broad enough in covering the entire scope of Christian history, which is (for the most part) theologically fair until the last two chapters, in which it derails and opinions abound without qualification or acknowledgment. There is also frequent misunderstanding of Catholic thought and minimal effort put into Orthodox thought, both historical and current, but honestly you can't have your cake and eat it too, so such mistakes are to be expected in a 500+ page overview of Christian thought.
