“Augustine occupies a privileged place among the Western Church Fathers that Aquinas invokes. Despite their affinity, some have proposed a division between these great theologians. Augustine’s theology is often characterized as “affective” while Aquinas is labeled merely “rational.” This distinction is misleading in many ways, and it implies that Augustine’s theology lacks reason or that Aquinas’s theology is lifeless.

For both of these theological giants, affection and reason belong together. Theology is not just something nice to think about. It matters what you think, precisely because our salvation is mediated through the mysteries of the faith.

We can see this approach in both Augustine’s and Aquinas’s writings on the mystery of the Trinity. Bridging the “gap” between reason and affect, Trinitarian theology is both an intellectual and spiritual exercise. Augustine and Aquinas both modeled this, as Father Gilles Emery, O.P. explains in his essay “Trinitarian Theology as a Spiritual Exercise in Augustine and Aquinas.” Both Doctors show how understanding the complexity of man’s mind and heart reveals an intimate relationship between us who know and love and God who is the Knower and Lover. This theological investigation can be difficult; it “exercises” the soul in a real sense. But it also prepares the soul for communion with the Triune God whose very being is Truth and Love.

For Augustine, elucidating the mystery of the Trinity requires great mental effort, but it also demands devotion. Our efforts to understand God must be informed by love because “the more one loves God, the more one sees Him” (Emery, 7). Because we are seeking the most supreme truth in such an endeavor, our souls must be trained through a kind of “spiritual gymnastics.” This theological regimen strengthens us to rise to the heights to see God and is purified through prayer, penance, and a life of virtue. Moved by God’s grace, theological study prepares us to see God in a limited way in this life and propels us to behold Him in the beatific vision. 

In his theology, Aquinas follows Augustine’s approach and builds on it. He delves into the mystery of the Trinity through speculative study, in order to enable believers to grasp the truth of God more deeply. Growing in knowledge of the Trinity both aids our contemplation and provides us with the means to defend the faith against error. Aquinas understands that by studying God, we come to recognize that our own knowing and loving is a mirroring of God Who is Knowing and Loving. This realization gives spiritual consolation to those who dwell in the darkness of this passing world, yearning for the light of the life to come.

As Augustine and Aquinas both demonstrate, true theology requires rational precision, but also an affective inclination to God. As the theologian—indeed any believer—rises to grasp the lofty mysteries of the Trinity he becomes ever more conformed to the God he seeks, and he receives already a foretaste of that vision he hopes to enjoy in glory.

Studying the Trinity stretches our minds. Theology that is both loving and rational lifts the soul in sacred study and puts one in contact with God. The shared theological approach of Augustine and Aquinas—integrating both reason and affection—is a model for teachers and students today. By seeking God through both wisdom and love, our deepest desire for God can be satisfied. God has made us for Himself, and both our hearts and minds are restless until they rest in Him (cf. St Augustine).”
