Sociologist Christopher A. Morrissey’s book Christianity and American State Violence in Iraq: Priestly or Prophetic? attempts to rethink the relationship of religion and violence by taking American Christians’ responses to the U.S. invasion of Iraq as a case study. The two terms in the title of the book, ‘priestly and prophetic,’ come from Max Weber’s work and Morrissey uses them to describe two different religious orientations toward the state and toward war. The priestly approach legitimizes and defends the state’s power and its war-making capacity, whereas the prophetic approach challenges it. The overall purpose of the book is to investigate whether Christians in the United States took a priestly or a prophetic approach in the context of the Iraq war, and to explain the variation among Christians regarding their perspectives toward the war.
