"By the start of the twenty-first century, evangelical Christianity had come to constitute the second largest grouping of Christian believers in the world. Only the Roman Catholic church enjoyed more Christian adherents than the evangelical churches. By comparison with other world religions, evangelicals-taken only by themselves-were more numerous than all but Muslims and Hindus. But what is meant by “evangelicals” or “evangelicalism”? These are by no means easy questions. The terms are even much disputed among those whom others casually lump together as evangelicals. Billy Graham, the American evangelist who was probably the world’s most widely known “evangelical” in the twentieth century, was repeatedly chastised throughout much of his public career by self-described “fundamentalists” for abandoning the separatism that they considered a non-negotiable aspect of the Christian faith. Yet most observers class “fundamentalism” as a subcategory of overlapping with “evangelicalism.” Yet most observers class “fundamentalism” as a subcategory overlapping with “evangelicalism.” David Yongi Cho, a Pentecostal minister, pastors the Yoido Full Gospel Church in Seoul, Korea. With over 700,000 members, as announced on its Web site, it is the largest single congregation in the world; the same Web site affirms that the church “practices faith, love, and service based on the cross of Christ and the Bible,” a strongly evangelical formula. Pastor Cho and his church have, however, been criticized by other self-described evangelicals as pagan for adapting Christianity to ancestral Korean practices (for example, the prayer mountain as replicating aspects of shamanism) and or replacing the Christian gospel with magical formulas that promise health and wealth. Yet most observers have no difficulty recognizing Cho’s brand of Pentecostal Christianity as a variety of evangelicalism."
