With respect to the field of Christian ethics of conflict, Scheid’s book offers an important evaluation and rereading of a tradition of thought that has rarely taken seriously what a just revolution might consist of. . . What Scheid’s book—in evaluating revolution by the classic restraints present in just war thinking—has provided is a far thicker vision of revolution than its predecessors. . . . As conflicts across the world continue to be perpetrated more and more by non-state actors, Scheid’s work is an invigorating example of how to think constructively in a new era without throwing out the traditions of the past.
