Thomas Aquinas and Karl Barth, though separated by hundreds of years, are often taken as two of Christianity’s greatest theologians. This collection of essays undertakes a systematic comparison of them through the lens of five key topics: (1) the being of God, (2) Trinity, (3) Christology, (4) grace and justification, and (5) covenant and law. Under each of these headings, a Catholic portrait of Aquinas is presented in comparison with a Protestant portrait of Barth, with the theological places of convergence and contrast highlighted. This volume combines a deep commitment to systematic theology with an equally profound commitment to mutual engagement. Understood rightly and well, Aquinas and Barth contribute powerfully to the future of theology and to an ecumenism that takes doctrinal confession seriously while at the same time seeking unity among Christians.
