Stephen Langton (c.1228), later Archbishop of Canterbury, was a prominent master of theology, belonging to the first generation of scholars working at the faculty of theology of the nascent University of Paris. The Quaestiones Theologiae constitute his chief speculative work. Book III, volume 1, offers a critical edition of 24 disputed questions on Christology and faith. Each question is accompanied by a critical apparatus and source notes. The edition is preceded by an extensive analysis of Langton's views. The volume also contains an important supplement to the study of the whole manuscript tradition of Langton's QQuaestiones Theologiae and offers the first general stemma codicum of the Quaestiones.
