Paul Tillich

Paul Johannes Tillich (; German: [ˈtɪlɪç]; August 20, 1886 – October 22, 1965) was a German and American Christian existentialist philosopher, religious socialist, and Lutheran theologian who was one of the most influential theologians of the twentieth century. Tillich taught at German universities before migrating to the United States in 1933, where he taught at Union Theological Seminary, Harvard University, and the University of Chicago. For the general public, Tillich wrote the well-received The Courage to Be (1952) and Dynamics of Faith (1957). His major three-volume Systematic Theology (1951–1963) was for theologians; in many points it was an answer to existentialist critique of Christianity. Tillich's work attracted scholarship from other influential thinkers like Karl Barth, Reinhold Niebuhr, H. Richard Niebuhr, George Lindbeck, Erich Przywara, James Luther Adams, Cardinal Avery Dulles, Dietrich Bonhoeffer, Sallie McFague, Richard John Neuhaus, David Novak, Thomas Merton, Michael Novak, and Martin Luther King Jr.
