Essays by D.G. Hart, Michael Horton, John Frame, Richard Gaffin, Robert Godfrey, and Edmund Clowney highlight this study of the crucial role the Westminster seminaries have played in the development of systematic theology during the past seventy-five years. This volume examines the contributions of theologians from John Murray and his Princeton predecessors, to Robert Strimple and beyond. Divided into four sections, the contributors examine the history of systematics, its relationship to other disciplines, issues of special importance, and the impact of Westminster theology on the broader life of the church. The essays are offered in the hope that they will contribute to the defense and progress of Reformed theology within the church in this new century.
