Book excerpt: The Spirit of American Liberal Theology is an interpretation of the entire U.S. American tradition of liberal theology. A highly condensed and far-more-accessible summary of Gary Dorrien’s three-volume trilogy, The Making of American Liberal Theology (Westminster John Knox Press 2001, 2003, and 2006), Dorrien here presses the argument that the most abundant, diverse, and persistent tradition of liberal theology is the one that blossomed in the United States and is still refashioning itself. While discussions of English and German liberalism persist, new material includes expanded treatment of the Black social gospel, the Universalists, developments into early 2020s, and a robust expression of the author’s post-Hegelian liberal-liberationist perspective.
