This book tells a surprising story. Many think of Christianity as a Western faith, which grew out of its origins in the Middle East towards Rome and into Europe, paving the way for the Enlightenment, science and modernity. However, Philip Jenkins reveals, the largest and most influential churches of Christianity's youth lay to the east of Rome, covered the world from China to North Africa, encountered a full spectrum of acceptance to persecution under Islamic rule and only expired after a thousand-year reign after Constantine. This is the story of these churches of the East and how they became extinct - but not before becoming the dominant expression of Christianity for its first 1,000 years and helping to shape both the Asia and the Christianity we know today.
