He discusses the role of dogma but also, uniquely, the critical factors that differentiate sects from religious communities and religions from sects. Following a thorough review of the structural characteristics of individual sects, Khuri addresses issues of religious change, dealing with the interplay between religions, states and nationalism. Here he explores the contradictions between modern state structures and the Islamic umma, showing how some religious concepts had begun to take on nationalistic meanings.
