Archdeacon Andrei Kuraev's book, "Sacred Wars of the Orthodox World," explores the phenomenon of religious violence and the justification of war in Orthodox history and theology. The author examines the Church's approach to war throughout the centuries, from Byzantium and Ancient Rus' to modern times. He focuses on the contradiction between the Gospel commandment of love and the practice of blessing weapons, as well as the ideology of "holy war" in the Orthodox tradition. Kuraev draws on historical sources, the texts of the Holy Fathers, documents of the Ecumenical Councils, and contemporary church statements, demonstrating how religious rhetoric has been used to justify state and military interests. The book raises pressing questions: can war be considered "righteous"? Where is the line drawn between the defense of faith and violence?
