" To state it more simply, the study of religion is chiefly the study of a certain kind of human behavior, be it under the rubric of anthropology, sociology, or psychology. The study of theology, on the other hand, is the study of God. Religion is anthropocentric; theology is theocentric. The difference between religion and theology is ultimately the difference between God and man—hardly a small difference. "
