Based on a national telephone survey and 300 personal interviews with evangelicals and other churchgoing Protestants, this study provides an analysis of the commitments, beliefs, concerns and practices of this group. Examining how evangelicals interact with and attempt to influence secular society, the text argues that traditional, orthodox evangelicalism endures because of the challenges and structures of our modern pluralistic environment. It also looks beyond evangelicalism to explore the problems of traditional religious belief and practice in the modern world.
