Gregory W. Lee (PhD, Duke University) is assistant professor of theology at Wheaton College. His academic interests focus on the appropriation of early Christian writers for contemporary theological reflection. His forthcoming book, "Today When You Hear His Voice": Scripture, the Covenants, and the People of God, explores the dynamics of scriptural authority in Augustine, Calvin, and the epistle to the Hebrews. His next major project will focus on Augustine's understanding of ecclesial sin and its implications for church division and the church-world relationship. He and his wife live in the North Lawndale area of Chicago, where they attend Lawndale Christian Community Church.
