Beliefs in witchcraft and demons still shape many societies and seem to be increasing rather than disappearing with modernization and urbanization. Witch hunts in Africa and Asia show the scope of the problem. The deliverance practices of Pentecostal and charismatic churches are widely controversial and their effects rather ambiguous. The contributions in this volume, written by experts and practitioners from four continents, analyze these phenomena from the perspectives of intercultural theology, anthropology and ethnology and describe the responses of Catholic and Protestant churches.
