One of the Greatest Ecclesiastical historians of the twentieth century, John Meyendorff held the underlying conviction throughout his career that there was and is an uninterrupted, consistent, and continuous holy tradition of faith held by the church throughout the centuries. Identifying that core of apostolic tradition, however, is seldom easy. This collection of essays in Meyendorff's honor carries forward his conviction by exploring the apostolic tradition from a variety of angles, periods, and disciplines. A distinguished team of international scholars offers new perspectives on historical theology by examining continuity and change in the history of Christian thought through fresh interpretations of Scripture, theology, liturgy, and spirituality. Classical themes and contemporary challenges are brought together to speak compellingly to the needs of Christianity today.
