It goes without saying that every religion makes a claim to truth and even to absolute truth. A single absolute truth, with a plurality of truths outside it, is a logical impossibility. This presentation will discuss the problem posed by this antinomy from the perspective of Christian and Orthodox theology, in the face of the pluralism of modern society and the need for peaceful coexistence among people of different faiths,. Inclusivism, exclusivism and religious pluralism are distinct approaches that are prominent in today’s discussion. Interiorism is yet another school of thought, which developed primarily in Germany. After discussing these main trends and their representatives, this presentation will consider the ancient patristic tradition and Orthodox approaches in modern times, and propose criteria for a Theology of Religions and the establishment of a global ethic.
