One of the most perplexing problems in Pauline studies is the meaning of the phrase pistis christou. Is Paul speaking of our faith in Christ or of Christ's own faithfulness toward God? Here noted contemporary New Testament scholars join forces—and lock horns—to shed light on the answer by presenting rigorous exegetical studies from both sides of the debate. They also bring fresh creative proposals to bear on the problem, and place the discussion in the wider spectrum of historical, biblical, and systematic theology. The most penetrating and comprehensive attempt to date to grapple with the significance of Jesus' faithfulness and obedience for Christian salvation, and the extent to which it is represented in key biblical texts. CONTRIBUTORS University of Durham luminary James D.G. Dunn authors an erudite foreword; and editor Michael Bird introduces the problems and prospects for a New Testament conversation on the topic. Debbie Hunn, Stanley E. Porter, and Andrew W. Pitts contribute essays about the background of the pistis christou discussion. Douglas A. Campbell, R. Barry Matlock, Paul Foster, and Richard Bell clarify Pauline texts in contention. Mark A. Seifrid, Francis Watson, Preston M. Sprinkle, and Ardel B. Caneday explore Pauline exegesis, hermeneutics, and theology. The witness of the wider New Testament is covered by Peter G. Bolt, Willis H. Salier, Bruce A. Lowe, and David deSilva. Finally, Mark W. Elliott and Benjamin Myers offer historical and theological reflections from the church fathers, Karl Barth, and others.
