This valuable study explores the Russian Enlightenment with reference to the religious Enlightenment of the mid to late eighteenth century. Grounded in close reading of the sermons and devotional writings of Platon (Levshin), Court preacher and Metropolitan of Moscow, the book examines the blending of European ideas into the teachings of Russian Orthodoxy. Highlighting the interplay between Enlightenment thought and Orthodox enlightenment, Elise Wirtschafter addresses key questions of concern to religious Enlighteners across Europe: humanity’s relationship to God and creation, the distinction between learning and enlightenment, the role of Christian love in authority relationships, the meaning of free will in a universe governed by Divine Providence, and the unity of church, monarchy, and civil society. Countering scholarship that depicts an Orthodox religious culture under assault from European modernity and Petrine absolutism, Wirtschafter emphasizes the ability of Russia’s educated churchmen to assimilate and transform Enlightenment ideas. The intellectual and spiritual vitality of eighteenth-century Orthodoxy helps to explain how Russian policymakers and intellectuals met the challenge of European power while simultaneously coming to terms with the broad cultural appeal of the Enlightenment’s universalistic human rights agenda.
