Subsidiarity, sphere sovereignty, and state sovereignty

Abstract

An important question for liberal political theory is whether its account of political morality is compatible with religious political thought. This paper examines one aspect of that broad question, namely the compatibility of the Christian pluralist tradition with liberalism's account of state sovereignty. According to Cécile Laborde, a central commitment of liberalism—and perhaps its most radical—is the claim that the state possesses a form of sovereignty that she dubs ‘competence-competence’. This refers to the state's meta-jurisdictional authority to decide the areas of competence of associations within it. The Christian pluralist tradition, in contrast, emphasises the independent authority of various kinds of social groups and the external limits this places on the state. The paper argues that, despite appearances to the contrary and the claims of many pluralist thinkers, these two views are compatible. It does so through a detailed examination of the two main strands of Christian pluralism, namely subsidiarity and sphere sovereignty, and by comparing pluralists’ and liberals’ approaches to the regulation of religious groups.
