Emil Brunner (1889–1966) was a Swiss Protestant theologian. A clear and systematic thinker from the school of dialectical theology, he was a professor of theology at the Univ. of Zürich (1924–53) and Christian University, Tokyo (1953–55). He several times visited and lectured in the United States. Like Karl Barth he challenged the leaders of modern rational and liberal Christian theology and proclaimed a theology of revelation. The Christian faith, he maintained, arises from the encounter between individuals and God as He is revealed in the Bible.
