The first English translation of Aquinas's Commentary on the Gospel of John by Fabian Larcher and James Weisheipl, originally published nearly two decades ago and long out of print, is available to scholars and students once again with this edition. Published in three volumes simultaneously, it includes a new introduction and notes pointing readers to the links between Aquinas's biblical commentary and his Summa theologiae. When a verse from the Gospel of John is directly quoted in the Summa theologiae, the editors note this in the Commentary. Aquinas's patristic sources, including Origen and Augustine, are carefully identified and referenced to the Patriologia Latina and Patrologia Graeca. The Commentary's connections with Aquinas's Catena Aurea are also identified. The three volumes in the Commentary on the Gospel of John will be sold individually and as a set.
