Thomas Aquinas — the dumb ox speaks

Aquinas at school in Paris

Thomas Aquinas is a big, slow-seeming young man from a noble family in southern Italy, and his fellow students at the University of Cologne call him the Dumb Ox because he is quiet in class and large in frame and does not demonstrate his intelligence by talking over everyone else.

His teacher, Albertus Magnus — the greatest encyclopedist of the medieval world — does not agree with their assessment. One day in class, when Thomas finally speaks, Albert reportedly says: You call this man a dumb ox, but he will one day fill the world with his bellowing.

Thomas has been placed in the Dominican order against his family's wishes. His brothers kidnap him and hold him in the family castle for a year to dissuade him. His mother eventually helps him escape out a window. He rejoins the Dominicans and never looks back.

At the University of Paris, where he studies under Albert and then teaches, he encounters the full force of the Aristotelian challenge. Aristotle's complete works have recently arrived in Europe via Arabic translation, and they present a comprehensive account of the world — physics, metaphysics, ethics, politics — built entirely on natural reason, without reference to scripture or revelation.

The Aristotelian system seems to many to threaten Christianity. Thomas sees it differently: Aristotle has described reality as far as unaided reason can describe it. Faith completes what reason begins. Grace perfects nature.

He sits down to write the most comprehensive synthesis of faith and reason in the history of Western thought.


Grace does not destroy nature but perfects it.

Thomas Aquinas, Summa Theologica I.8.2, c. 1265 AD

Romans 1:20

For the invisible things of him since the creation of the world are clearly seen, being perceived through the things that are made, even his everlasting power and divinity; that they may be without excuse.


Grace does not destroy nature but perfects it. This is the foundation of everything Aquinas builds — the conviction that creation is not the enemy of redemption but its material, that the world God made is not a trap to escape but a theater in which grace works.

This has practical implications in every direction. It means that natural knowledge — science, philosophy, medicine, law — is not the enemy of faith but its companion. It means that the body is not a prison for the soul but a genuine part of the person God saves. It means that the ordinary human goods — friendship, beauty, justice, pleasure — are not spiritual dangers but participations in God's own goodness.

Aquinas gives the Christian tradition permission to love the world that God loves.

Do you experience your faith as perfecting your humanity or suppressing it? And what would a faith that perfected rather than suppressed look like in your ordinary life?
