“In 1900 religionists—people following and studying religions—assumed Islam would become the religion of Africa. They were wrong. They thought Christianity would remain strong in the West. They were wrong. They assumed Christianity would continue to look Mainline, Catholic, and Orthodox. They were wrong: Pentecostalism was not even a concept at the time.
Historians were wrong because they and politicians were progressive; they thought everything would get better and better. The Russian Revolution, Armenian genocide, and the Great War put all those ideas to bed.”
