Christianity has transformed many times in its 2,000-year history, from its roots in the Middle East to its presence around the world today. From the mid-twentieth century onward the presence of Christianity has increased dramatically in Asia, Africa, and Latin America, and the majority of the worlds Christians are now nonwhite and non-Western. The Encyclopedia of Christianity in the Global South traces both the historical evolution and contemporary themes in Christianity in more than 150 countries and regions. The volumes include maps, images, and a detailed timeline of key events. The phrases “Global Christianity” and “World Christianity” are inadequate to convey the complexity of the countries and regions involved—this encyclopedia, with its more than 500 entries, aims to offer rich perspectives on the varieties of Christianity where it is growing, how the spread of Christianity shapes the faith in various regions, and how the faith is changing worldwide.
