Written by leading experts on Aquinas's theology, the essays in Reading John with St. Thomas Aquinas bear common witness to a central theological conviction: the tasks of biblical exegesis and speculative theology, though distinct, indwell and inform each other. As the first book-length study of the full breadth of Aquinas's Commentary on the Gospel of John, this work illuminates the way in which thinking systematically or speculatively about revelation flows from questions raised within biblical exegesis itself. Like any medieval biblical commentator, Aquinas attempts to understand a biblical text not only in itself but also by appealing to parallel interpretive texts drawn from throughout the Bible as well as the accumulated insights of the Church Fathers. This method enables him to penetrate deeply into the thought of the Bible, recognizing that the biblical authors - speaking from within the context of Israel and the Church - raise questions that are theological and that belong to coherent speculative theological frameworks. The result is, in large part, a speculative theological commentary that is not imposed on the biblical texts but emerges from it. necessary conjunction of the inspired words of Scripture, exegetical commentary, and theological analysis. The volume is both a study of Aquinas's thought and an attempt to foster contemporary exegetical approaches that emphasize the need to interpret Scripture speculatively, through the historical lens of tradition.
