Augustinian Theology in the Later Middle Ages

Volume 1: Concepts, Perspectives, and the Emergence of Augustinian Identity


The culmination of thirty years of research, Eric Leland Saak’s Augustinian Theology in the Later Middle Ages offers a comprehensive, new interpretation of late medieval Augustinianism. The first of a two-volume work, the present book sets the stage and analyzes the conceptual and methodological structures requisite for interpreting the reception of Augustine in the later Middle Ages historically, together with explicating the first two of the four “pillars” of Augustinian theology: the Augustinian Hermits’ political theology; the teaching in the Order’s schools; the Order’s university theology; and its moral theology. Holistically fused with the Order’s religious identity, these distinct yet interconnected components of Augustinian theology, rather than a narrow, theologically defined anti-Pelagianism, provided the context for the emergence of the Reformation.
