The Companion to the Theology of John Mair explores the major theological themes present in Mair's commentary on the Sentences of Peter Lombard. Mair is often noted for his importance as a leading sixteenth-century Parisian intellectual. The essays in this volume explore his influence as a teacher and thinker in this critical place and time. The volume gives special consideration to his attitude toward humanism and his deep familiarity with the scholastic past. The book is divided into four sections. It explores Mair's attitude toward faith and theology, his theological metaphysics, his ethics and role in the development of moral casuistry, and his views on justification and sacramentology. The volume likewise includes a substantial appendix (including an edition of the table of questions for all four books of Mair's commentary) aimed to assists scholars in further exploration of Mair's Theology.
