Using examples such as the Yoido Full Gospel Church in Seoul, Korea, ‘Megachurches, cells, and progressive Pentecostalism’ discusses the role of these institutions. One of the secrets of Pentecostal life and growth lies in the enormous range of opportunities given to men and women of many different talents to express their faith. Megachurches match the urbanization of the contemporary world and, within these complicated and creative structures, Christians can either live in a protected environment or else be prepared for engagement with contemporary culture. The older unworldly congregations of holiness are being transformed into high-tech communities of faith attractive to young people. From these and other bases, Pentecostals can launch humanitarian projects.
