The late Professor John Romanides, a graduate and, subsequently, a Professor of Holy Cross Greek Orthodox School of Theology in Brookline, Massachusetts (1958-1965), and a Professor of the Aristotle University of Thessalonica, Greece (1968-1984) was one of the most original theologians of Eastern Orthodox Christianity worldwide in the second half of the 20th century. Raised in America and having become familiar with Western Christians, Roman Catholics and Protestants, as well as Western theological scholarship, both through his upbringing and his involvement in the modern Ecumenical Dialogues, he developed a critical and highly original Eastern Orthodox approach to Christian theology. He identified his approach with the Christian Roman ecumene that was centered in Constantinople, New Rome. His views on Christian Romanity and Roman Orthodoxy have earned him the title of Prophet of Roman Orthodoxy and have given rise to a school of committed followers and to much discussion. This book is Romanides' first Outline of Orthodox Patristic Dogmatics, which is published for the first time in the original Greek and in English translation. It represents a concise introduction into his understanding of the basic tenets of the Eastern Orthodox Faith and its fundamental differences from those of Western (Augustinian or Franco-Latin) Christian theology. It covers such doctrines as God's relation to the world, the doctrine of the Holy Trinity, the doctrine of Christ, the doctrine of the Church, the Church's Holy Tradition and the restoration and perfection of humanity in and through this Tradition. It will serve as an introduction into this theologian's original vision of Patristic Orthodoxy, which is the basis of his reappraisal of Christian theology and history. Its value lies in its concise, coherent and comprehensive character.
