In recent years evangelical Christians have been increasingly turning their attention toward issues such as the environment, international human rights, economic development, racial reconciliation, and urban renewal. Such engagement marks both a return to historic evangelical social action and a pronounced expansion of the social agenda advanced by the Religious Right in the past few decades. For outsiders to evangelical culture, this trend complicates simplistic stereotypes. For insiders, it brings contention over what "true" evangelicalism means today.Beginning with an introduction that broadly outlines this "new evangelicalism," the editors identify its key elements, trace its historical lineage, account for the recent changes taking place within evangelicalism, and highlight the implications of these changes for politics, civic engagement, and American religion. The essays that follow bring together an impressive interdisciplinary team of scholars to map this new religious terrain and spell out its significance in what is sure to become an essential text for understanding trends in contemporary evangelicalism.
