Thomas Aquinas

1225 – 1274

Scholastic — Theology/Philosophy

Thomas Aquinas was born around 1225 at Roccasecca, near Aquino in southern Italy, the youngest son of Count Landulf of Aquino. His family held considerable political influence in the region, with connections to both the Holy Roman Emperor and the Pope. At age five he was sent to the Benedictine monastery of Monte Cassino for his early education, where his uncle served as abbot. The family likely intended him for an ecclesiastical career that would advance their political interests.

Around 1239 Thomas was sent to the University of Naples, recently founded by Emperor Frederick II. There he encountered the works of Aristotle and came into contact with the Dominican friars. Against fierce family opposition, he joined the Dominican order in 1244 at age nineteen. His family was so outraged by this decision — the Dominicans were a mendicant order that embraced poverty, unlike the wealthy Benedictines — that his brothers kidnapped him and held him prisoner for nearly two years at the family castle, attempting to break his resolve. They even sent a prostitute to his room to seduce him away from his vocation. Thomas reportedly drove her away with a burning brand from the fireplace.

Released in 1245, Thomas went to Paris to study under Albert the Great, the most prominent Dominican intellectual of his time. He followed Albert to Cologne in 1248, where he began his teaching career. His fellow students initially called him "the dumb ox" because of his quiet demeanor and large frame, but Albert famously predicted that "this ox will fill the world with his bellowing." Thomas returned to Paris in 1252 to complete his theological doctorate, becoming a master in 1256 despite significant opposition from secular clergy who resented the mendicant orders' growing influence in the universities.

Thomas spent his career moving between Paris, Italy, and various Dominican houses, always writing. He taught at the papal court, advised popes, and was called upon to settle theological disputes. He established Dominican schools of theology in Rome and Naples. His method was revolutionary: while most theologians remained suspicious of pagan philosophy, Thomas systematically integrated Aristotelian thought with Christian doctrine, arguing that reason and faith were complementary paths to truth. This synthesis was controversial and faced considerable resistance during his lifetime.

He died on March 7, 1274, at the Cistercian monastery of Fossanova while traveling to the Council of Lyon. He was forty-eight. Some of his propositions were condemned by the Bishop of Paris in 1277, three years after his death, but he was canonized in 1323 and declared a Doctor of the Church in 1567.

His Writing and Its Influence

Thomas began writing in earnest during his first period as a master in Paris in the 1250s. His earliest major work was a commentary on Peter Lombard's Sentences, the standard theological textbook of the medieval universities. But his distinctive voice emerged in his systematic integration of Aristotelian philosophy with Christian theology, most fully realized in his two great syntheses: the Summa contra Gentiles (completed around 1264) and the Summa Theologica (begun around 1265 and left unfinished at his death).

The Summa Theologica was designed as a textbook for students beginning theology, though its scope and depth far exceeded any introductory text before or since. Written in the form of questions and articles, it addresses virtually every aspect of Christian doctrine through rigorous logical analysis. Thomas's method was to state a question, present objections, cite contrary authorities, and then provide his own reasoned solution. The work demonstrates an extraordinary mastery of Scripture, the Church Fathers, canon law, and both Christian and non-Christian philosophy.

Thomas wrote prolifically — biblical commentaries, disputed questions, treatises on specific topics, hymns for the feast of Corpus Christi. His complete works fill more than forty volumes. But it was the Summa Theologica that became the foundation of Catholic theological education for centuries. The Council of Trent drew heavily upon his work, and in 1879 Pope Leo XIII's encyclical Aeterni Patris officially endorsed Thomistic philosophy as the basis for Catholic intellectual life.

His influence extends far beyond Catholicism. Protestant Reformers, while rejecting his synthesis of reason and revelation, engaged seriously with his arguments. Modern philosophers from diverse traditions continue to wrestle with his contributions to metaphysics, ethics, and political theory. Contemporary evangelical theologians have increasingly recognized the value of his theological method and his treatment of classical Christian doctrines.

Who should read Thomas Aquinas: Readers who want to understand how the greatest theological mind of the medieval period worked through fundamental questions about God, creation, human nature, and salvation. He is essential for anyone seeking to grasp the intellectual foundations of Catholic theology, but also valuable for Protestants who want to engage with the broader Christian tradition's most systematic thinker. He is not for those looking for devotional warmth or practical spirituality — Thomas writes as a professor addressing students, with precision rather than passion. He rewards readers willing to think carefully about ultimate questions and to follow rigorous logical arguments wherever they lead.
