Based on a national telephone survey and more than three hundred personal interviews with evangelicals and other churchgoing Protestants, this study provides a detailed analysis of the commitments, beliefs, concerns, and practices of this thriving group. Examining how evangelicals interact with and attempt to influence secular society, this book argues that traditional, orthodox evangelicalism endures not despite, but precisely because of, the challenges and structures of our modern pluralistic environment. This work also looks beyond evangelicalism to explore more broadly the problems of traditional religious belief and practice in the modern world.
