You may not know Reinhold
Niebuhr, but you know Reinhold Niebuhr. At least you do if
you've ever read that "man's capacity for justice makes

Gary Dorrien, professor at
Union Theological Seminary and Columbia University, has called him "the
most important thinker of the past century concerning the relation of
Christianity to problems of social ethics and politics." Time went

Jonathan Edwards." His career as a pastor, theologian, professor, author,
and social commentator left an indelible imprint on intellectual life in the
20th-century United States.
