Book excerpt: St. Thomas Aquinas is best known for his Summa Theologiae and is regarded as the great exemplar of systematic theology. Yet St. Thomas himself might be surprised at this legacy. He may well have saw himself principally as a commentator and teacher of Sacred Scripture. When it comes to engaging St. Thomas’ scriptural work, readers are at a significant disadvantage. They are arguably more foreign and more dense than his Summa yet have been scarcely studied. This book by one of the foremost experts on St. Thomas’ use of Scripture is a significant and much needed contribution. In The Order and Division of Divine Truth: St. Thomas Aquinas as Scholastic Master of the Sacred Page, John Boyle opens up the riches of St. Thomas as a master of the Sacred page. Readers will find explorations not just of the style of Aquinas’ commentaries, which differs from that of the modern biblical commentary, but also the overarching theological and methodological perspective that shapes his approach to Scripture. Boyle gives insight into how Aquinas would have understood the task of biblical commentary as a university lecturer, how Scripture is ordered to divine revelation, how medieval masters divided up the text, and how Aquinas’ biblical commentaries relate to his theological summaries. This book will be important for anyone seeking to better understand St. Thomas’ theology and the often-overlooked role that Scripture plays in his work.
