Factionalism and schism have marked each of the three great faiths we have studied. discuss the origins and legacy of the sunni-shi’a split, the split between luther with his supporters in germany and the church (later called the roman catholic church), and the emergence of reform judaism in distinction from traditional judaism. how were each of these schisms driven by disagreements over who or what was authoritative in the respective traditions? are authority and power synonymous or not? what do these conflicts tell us about the relation of authority and power—whether they are synonymous or not—in the respective faith traditions and in conflict in the western religious traditions more broadly?
