Augustine and Reformed Theology Compatibility

Yes, historically speaking, Augustinian thought serves as the very foundation upon which Reformed theology is built. The Reformation is best understood not just as a revival of religion, but specifically as a great revival of Augustinianism [5].

When the Reformers sought to articulate their understanding of grace, they frequently looked to Augustine as their primary teacher and guide [1, 6]. In fact, the Reformed tradition has historically viewed its own doctrine of predestination and grace as an extension of the work of Augustine and his disciples, such as Prosper and Fulgentius [3, 4]. During the Reformation and even in later seventeenth-century discussions, Reformed thinkers often presented their positions simply as "Augustinianism," believing their understanding of the absolute sovereignty of God and the helplessness of the sinner to be the same doctrine Augustine defended against his opponents [3, 4].

The influence of Augustine is so deeply woven into the Reformed tradition that B.B. Warfield even challenged followers of Thomas Aquinas to recognize that the Reformed doctrine of grace was the very same teaching they received from their own master, Augustine [2]. While the scholastic tradition of the Middle Ages also claimed Augustine as a primary authority, the Reformers found in him a "haven of rest" regarding the sovereignty of God that became the central pillar of their theological consciousness [5, 6].

For context: While Augustine is a cornerstone for the Reformed tradition, it is worth noting that he is also a central figure in the history of the Latin Church and was a foundational influence for medieval scholastic thinkers like Aquinas and Bernard of Clairvaux, each of whom engaged with his work in their own ways [6].
