The New York Times bestselling history of early Christianity in Africa, Asia, and the Middle East—from "one of America's best scholars of religion" (The Economist). In this groundbreaking book, renowned scholar Philip Jenkins explores a vast and forgotten network of the world's largest and most influential Christian churches that existed to the east of the Roman Empire. These churches and their leaders ruled the Middle East for centuries and became the chief administrators and academics in the new Muslim empire. The author recounts the shocking history of how these churches—those that had the closest link to Jesus and the early church—eventually died. Jenkins offers a new lens through which to view our world today, including the current conflicts in the Middle East, Asia, and Africa. Without this lost history, we lack an important element for understanding our collective religious past. By understanding the forgotten catastrophe that befell Christianity, we can appreciate the surprising new births that are occurring in our own time, once again making Christianity a true world religion.
