This book is about the medieval church. It contains stories of different people during that time.
Some people it talks about are: Gregory the Great, who was an archdeacon in Pope Pelagius's time, Anslem, who was an archbishop and died in 1109, Francis, who thought he was destined to become a knight, but ended up becoming a monk and founding the Franciscans, and John Wycliffe, who wrote against the wrong things that the church was doing, like being too concerned about wealth and power.
It also talks about different councils, the crusades, and the first university.
This was a pretty good book, but I got bored reading it. History isn't my favorite thing to read, but it's still a good book.
