While the revelation of God's name is a central theological topic, its ethical and political significance are often overlooked. In a world filled with violence committed 'in the name of God', how might invoking God's name enable peace, community, and hope? The Politics of Praise argues that the redemptive potential of naming God lies in how this event transforms friendship. It breaks new ground by tracing the connections between naming God and friendship in the work of Thomas Aquinas and Jacques Derrida. Advancing an innovative reading of Aquinas on the divine names, the book explores how Dionysius' mysticism shapes Aquinas' appropriation of Aristotle's ethics, then retraces how Derrida's reading of religion renders possible an alternative conception of friendship. These explorations lead to a surprising convergence between Aquinas and Derrida on the conditions of friendship.
