Orthodox Christian theology is often presented as the direct inheritor of the doctrine and tradition of the early Church. But continuity with the past is only part of the truth; it would be false to conclude that the eastern section of the Christian Church is in any way static. Orthodoxy, building on its patristic foundations, has blossomed in the modern period. This volume focuses on the way Orthodox theological tradition is understood and lived today. It explores the Orthodox understanding of what theology is: an expression of the Church's life of prayer, both corporate and personal, from which it can never be separated. Besides discussing aspects of doctrine, the book portrays the main figures, themes and developments that have shaped Orthodox thought. There is particular focus on the Russian and Greek traditions, as well as the dynamic but less well-known Antiochian tradition and the Orthodox presence in the West.
