Christoph Keller, III is an Episcopal priest and theologian. Born in El Dorado, Arkansas, he grew up in Arkansas and Mississippi. A 1977 graduate of Amherst College, he holds a doctorate (ThD) in Anglican Studies from General Theological Seminary in New York, where his field of emphasis was theology and science. His dissertation, "Darwin's Science in Chalcedonian Imagination," defends and explains compatibility between Christian faith and natural evolution. In 2012, he started SUMMA: A Student Theological Debate Society, with forty-seven high school students from central Arkansas. SUMMA, whose theme is "speaking truth in love," is now a summer program of the University of the South in Sewanee, TN, drawing students from around the world. As a pastor, he has served churches in Pine Bluff, Fort Smith, and Van Buren, Arkansas. In 1991, he started Little Rock's St. Margaret's Church, which initially met in a bargain cinema. From 2014 to 2020, he served as Dean and Rector of Trinity Cathedral, Little Rock. Getting On Toward Home: And Other Sermons by the River is his first book.
