Catholic ecclesiology stands at the threshold of a new moment in the reception of the Second Vatican Council. The election of Pope Francis—coinciding with the fiftieth anniversary of the council—has inspired a fresh consideration of its teaching in such diverse areas as ecumenism, inculturation, missiology, and ministry. The chapters in this volume have their origin in a special symposium that called together over forty of the leading Catholic scholars from throughout North America in order to discuss the future of theological reflection on the church. The nine essays in this volume guided that conversation and offer an entry into some of the most pressing issues in ecclesiology today.
