In Thomas Aquinas, Theologian Thomas O'Meara considers Aquinas the theologian and his influence, past and present. O'Meara focuses on Aquinas as teacher and preacher, and theology as the subject of his thought and most of his writings. Studying the Summa Theologiae as well as providing an overview of six centures of interpretation, O'Meara shows how few have understood the structure and intent of Aquinas' theology.
