This book is a jeremiad against 'new' versions of evangelicalism marketers and emergents and a summons to return to the historic faith, defined by the Reformation solas (grace, faith, and Scripture alone) and by a high regard for doctrine. Wells argues that historic, classical evangelicalism is marked by doctrinal seriousness, as opposed to the new movements of the marketing church and the emergent church. He energetically confronts the marketing communities and their tendency to try to win parishioners as consumers rather than worshipers, advertising the most palatable environment rather than trusting the truth to be attractive. He takes particular issue with the most popular evangelical movement in recent years the emergent church. Emergents, he says, are postmodern and postconservative and postfoundational, embracing a less absolute understanding of the authority of Scripture than traditionally held. The Courage to Be Protestant is a forceful argument for the courage to be faithful to what Christianity in its biblical forms has always stood for, thereby securing hope for the church's future.
