This book, widely regarded as groundbreaking since its publication over thirty-five years ago, sheds light on the more radical and prophetic roots of American evangelicalism and has challenged countless readers to rethink their evangelical heritage. It argues that nineteenth-century American evangelicals held a more mature vision of the faith, for they engaged demanding justice, peace, and social issues--a vision that was betrayed and distorted by twentieth-century neo-evangelicals. The book helps readers understand that the broader origins of American evangelicalism include the social justice concerns of today's church. Featuring new historic photos and illustrations, this edition includes new introductory and concluding chapters and incorporates relevant updates. The previous edition was published as "Discovering an Evangelical Heritage."
