Nearing thirty-five years ago, E. P. Sanders famously stated that the center of thought within Paul's theology is participatory in nature - which, of course, caused no small debate within broad strands of Pauline scholarship. Sanders also suggested that we have no modern conception of what this thought might mean for us today. These two axioms of Sanders loosely organize the essays in this volume which seek to explore the complex notions of union and participation within Pauline theology through exegesis, highlights in reception history, and theological reflection.
