This collection of essays explores convergences and divergences between process thought and Roman Catholicism with the goal of identifying reasons for why process philosophy and theology has not had the same impact in Roman Catholic circles as in Protestantism, and of constructively navigating avenues of promising engagement between Process thought and Roman Catholicism. In creatively considering the Roman Catholic tradition from the vantage point of Process thought, different theoretical perspectives are brought to bear on Catholic characteristics of historical theology, fundamental theology, systematic theology, moral theology, social justice, and theology of religions. While the contributors draw upon a broad range of resources from the disciplines of the physical and social sciences, philosophy, and ethics from a process perspective, the primary methodology employed is theological reflection.
