What has Seoul to do with Kampala? In the 1980s, the term “Global South” gained currency as a means of describing those parts of the planet outside the advanced regions of Europe, North America and Japan. Various writers, including myself, noted the dramatic rise of Christian numbers in that vast region.
The problem, of course, is that the whole concept of the Global South is outrageously broad, including as it does some very heavily developed regions, like South Korea, and many countries characterized by cataclysmic poverty and underdevelopment, such as the Congo. We should not use a term as vague as “Global South Christianity” without careful qualification. I tend to use it with the plural and speak of “Christianities.”
