New Testament studies are witnessing many exciting developments, and Douglas Campbell's groundbreaking publications offer an important contribution to future discussions about Paul. Campbell tackles familiar problems relating to justification, 'old' and 'new' perspectives, and much more besides, in fresh and exciting ways. In doing so he sets down one profound challenge after another to all those involved in Pauline studies. As a consequence, his work demands extended and serious deliberation. This book seeks to facilitate academic engagement with Campbell's work in a unique way. It contains chapters summarizing key themes in his thinking, reflections from friendly critics that aim to challenge or extend his ideas, and his own response to these interlocutors. In this way, the book allows readers to be drawn into a vitally important conversation. It is academic theology in the making and constitutes a cutting edge in Pauline studies.
