Using sermons, exorcisms, letters, biographies of the saints, inscriptions, autobiographical and legal documents--some of which are translated nowhere else--J. N. Hillgarth shows how the Christian church went about the formidable task of converting western Europe. The book covers such topics as the relationship between the Church and the Roman state, Christian attitudes toward the barbarians, and the missions to northern Europe. It documents as well the cult of relics in popular Christianity and the emergence of consciously Christian monarchies.
