This article sketches the global ethic proposed by Hans Küng and how Pope Francis’s writings on a culture of encounter help advance it. Religious nationalism impedes the development of this global ethic. Küng’s global ethic resists this nationalism and Francis’s approach provides guidance on whether the local or the global should take priority in concrete circumstances. The contributions of Küng and the pope are complementary and together can advance the ethic needed for greater justice and peace in a globalizing world.
