Catholicity Under Heaven: Reformed Ecclesiology and Chinese Visions of Cosmopolitanism

Reformed catholicity suffers from a fragility that causes it to easily fragment over comparatively small differences. This study wagers that an important resource that can be useful for addressing this problem is the Chinese philosophy of tianxia. The article introduces the idea of a ‘Reformed catholicity under Heaven’ by placing a more liberal interpretation of tianxia in conversation with the problems in Reformed approaches to the church’s catholicity. In doing so, the article demonstrates tianxia’s ecclesiological usefulness while articulating two dimensions of ‘Reformed catholicity under Heaven’ that can deepen how Reformed churches inhabit catholicity in ways that promote unity.
