St. Thomas Aquinas: Master of Scripture

St. Thomas Aquinas invites us to a deep and thorough knowledge of Scripture. While many aspects of the biography of the Angelic Doctor are familiar—he composed the hymns Tantum ergo and Panis Angelicus, he commented on the philosophy of Aristotle, he wrote the unfinished theological masterpiece, the Summa theologiae—it does not often come to mind that Aquinas was a master of Sacred Scripture. In fact, this was his official title as a professor at the University of Paris in the 13th century. More importantly, however, Scripture profoundly shaped Aquinas in both his person and his work. The writings of Aquinas invite us, under his guidance, to form for ourselves a thoroughly Scriptural imagination, which conforms us to Christ himself, in order to know and love Christ more deeply and imitate his example.

Aquinas was formed in Scripture by two great spiritual movements in the 13th century. As a child, young Thomas was educated at the Benedictine monastery in Monte Cassino, Italy. There he was exposed to the already ancient tradition of lectio divina, the prayerful reading and meditation upon Scripture as an entire way of life. As a teenager, Thomas enrolled at the University of Naples and, against his family’s wishes, joined the radical new mendicant order, the Order of Preachers, commonly known as the Dominicans. Both the Benedictine and Dominican ways of life were centred on Scripture, though in different ways. Benedictines stayed in the monastery, where they dedicated themselves to the mission of personal holiness through lectio divina. Dominicans went out into the world; having studied Scripture, they dedicated themselves to the mission of preaching and the care of souls.

The thorough shaping of one’s life by Scripture was aided by the particular educational resources of the 13th century. This period of history may be characterized as a memorial culture. Because of the scarcity of books, training of one’s memory is needed for literacy and education. In contrast, our culture may be described as a written culture, or even a digital culture. We depend on physical books and digital media for the transmission of information. With the dominant influence of Christianity in the 13th century, remembering Scripture was the foundation of literacy and education. Memorization, however, was not done merely in a rote way, which is how we tend to think of memorization. Rather, training the memory in the 13th century involved carefully dividing up a text into meaningful units, which could then be commented upon and/or recombined in various compositions, for example, for personal meditation, as the monks did, or for preaching, as the mendicants did.

We get a good sense of what this involves from the Biblical Commentaries of Aquinas. These commentaries show us how Aquinas invites us to know more deeply and thoroughly the words of Scripture. This certainly presupposes familiarity with the entirety of Scripture, immediately inviting us to read the Bible from beginning to end. But the primary exercise that we are invited to perform is to read one part of Scripture in light of another, to interpret Scripture according to Scripture. Doing this is what helps us to know more deeply and thoroughly the words of Scripture. We already receive training in this at Sunday Mass, where the First Reading, often from the Old Testament, is chosen because of some definite relation to the Gospel Reading. The preacher ought to help us make these connections. Studying the Biblical Commentaries of Aquinas supplements this training, and further develops our Scriptural imagination.

Let’s see how Aquinas does this in his Commentary on the Gospel of John. An illustrative example is Christ’s new commandment of love: “I give you a new commandment, that you love one another. Just as I have loved you, you also should love one another” (John 13:34). As we mentioned, the first step in medieval reading of the Bible is to divide up the text into meaningful units. Aquinas divides Christ’s words into three parts: first, Christ mentions the quality of the commandment in its newness (“I give you a new commandment”); second, Christ tells us what he commands (“that you love one another”); and third, Christ gives us an example of what he commands (“Just as I have loved you, you also should love one another”). I will discuss only the first consideration, the newness of Christ’s commandment. Aquinas draws us into a profound meditation on this newness.

Aquinas uses the standard medieval format of the ‘question’ in his commentary here. The format of questioning is not meant to lead us into doubt, but to deepen our understanding, especially when one part of Scripture appears to contradict another. Since there is already a commandment about loving one’s neighbour elsewhere in Scripture, how can Christ’s commandment be said to be new? Christ himself knows the Old Testament command to love one’s neighbour. In the Gospel of Matthew, the Pharisees ask Christ, “Teacher, which commandment in the law is the greatest?” (Matthew 22:36). Christ replies, “‘You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.’ This is the greatest and first commandment. And a second is like it: ‘You shall love your neighbour as yourself’” (Matthew 22:37-39). Christ directly quotes Leviticus 19:18.

It is clear that Christ’s new commandment is already formulated in the Old Testament. Aquinas resolves the question by suggesting three particular ways that Christ’s commandment can be said to be new. He plays on the meaning of newness, drawing in other parts of Scripture to perform his commentary.

First, Christ’s commandment is new because it produces renewal within us. St. Paul discusses this renewal at length in Colossians 3, and Aquinas brings this discussion to mind by quoting verses 9-10: “you have stripped off the old self with its practices and have clothed yourselves with the new self, which is being renewed in knowledge according to the image of its creator.” Aquinas sums up the teaching of St. Paul by identifying the root of the new self and its practices: charity, the love of God and neighbour, to which Christ urges us by giving us the new commandment to love one another.

Second, Christ’s commandment is new because of its source and cause, which is a new spirit, the Holy Spirit himself. Aquinas explains that there are two spirits, old and new. The old spirit was a spirit of slavery, and the new spirit is the Spirit of Love, who makes us adopted children of God. St. Paul teaches this explicitly in Romans 8:15: “For you did not receive a spirit of slavery to fall back into fear, but you have received a spirit of adoption.” This fulfills the promise of Ezekiel 36:26: “A new heart I will give you, and a new spirit I will put within you.” Aquinas completes this explanation of Scripture according to Scripture by quoting Romans 5:5, “God’s love has been poured into our hearts through the Holy Spirit that has been given to us.” This relates the first and second ways together: we are renewed in our hearts by a new spirit, the Holy Spirit, who is the cause of the charity that makes us new.

Third, Christ’s commandment is new because it establishes the New Covenant. Again, the New and Old Covenants are marked respectively by a difference between love and fear. The Old Covenant itself points toward the New, as it says in Jeremiah 31:31: “I will make a new covenant with the house of Israel.” This passage goes on to describe the New Covenant: “I will put my law within them, and I will write it on their hearts; and I will be their God, and they shall be my people.” Aquinas’ discussion of the establishment of the New Covenant as a way in which Christ’s commandment is said to be new helps to explain the appearance of the commandment to love one’s neighbour in the Old Testament. This command is given as preparation for Christ’s new commandment.

Aquinas’ commentary on the newness of Christ’s commandment to love one another deepens our understanding of this commandment according to the words of Scripture itself. We experience the newness of this commandment when we act from it, namely, when we act out of charity toward our neighbour. The cause of this charity in us is the Holy Spirit himself, the cause of our renewal, who produces the enduring effect of the New Covenant between God and human beings. Aquinas helps us to read Scripture—the Old in light of the New, and the New in light of the Old—in order to understand how God’s Spirit has brought newness to our hearts, a new relation between God and human beings, such that we can have new selves that can truly love our neighbours, following both Christ’s command and his example. This, in fact, summarizes the very intention of Scripture, to which Aquinas invites us as an entire way of life.
