The Lost History of Christianity: The Thousand-Year Golden Age of the Church in the Middle East, Africa, and Asia—and How It Died

by Philip Jenkins

The statistics of decline are sobering. Look, for instance, at Asia Minor, the region that is so often mentioned throughout the New Testament: it is here that we find such historic names as Iconium and Ephesus, Galatia and Bithynia, the seven cities of the book of Revelation. Still in 1050, the region had 373 bishoprics, and the inhabitants were virtually all Christian, overwhelmingly members of the Orthodox Church. Four hundred years later, that Christian proportion had fallen to 10 or 15 percent of the population, and we can find just three bishops. According to one estimate, the number of Asian Christians fell, between 1200 and 1500, from 21 million to 3.4 million. In the same years, the proportion of the world’s Christians living in Africa and Asia combined fell from 34 percent to just 6 percent. Actually, the contraction outside Europe was probably more dramatic than even these figures suggest, but the basic point is accurate.
