The book "Svyashchennye voyny pravoslavnogo mira" by Protodiakon Andrey Kuraev explores the phenomenon of religious violence and the justification of wars in the history and theology of Christianity. The author analyzes how the Church has viewed wars over the centuries, from Byzantium and ancient Russia to modern times. The focus is on the tension between the evangelical 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, texts from the Church Fathers, documents from ecumenical councils, and contemporary church statements to demonstrate how religious rhetoric has been used to justify state and military interests. The book addresses pressing questions: Can a war be considered "just"? Where is the line between protecting the faith and violence? This publication is aimed at anyone interested in the history of religion, the philosophy of war, and the role of the Orthodox Church in social life.
