Sanctified Life
1225 — 1274
Also Known As
"Wonder is the desire for knowledge."
Thomas Aquinas reconciled Aristotle with Christian revelation, arguing that faith and reason are not enemies but complementary paths to the same Truth. He abandoned a noble family's ambitions for him — a prestigious Benedictine abbacy — to join the mendicant Dominicans, surviving kidnapping by his own brothers to pursue the vocation. Yet after a mystical vision near his death in 1274, he stopped writing the unfinished Summa Theologiae, declaring all he had written 'like straw' compared to what God had revealed.

Life & Times
Early Life
Born 1225 in Roccasecca, Kingdom of Sicily. He defied his noble family's plan for him to become Abbot of Monte Cassino, choosing instead to join the Dominican friars — a decision that led his brothers to kidnap and imprison him for over a year.
Turning Point
Sent to Cologne around 1248 to study under Albert the Great, his silent, deliberate manner earned him the mocking nickname 'The Dumb Ox', to which Albert replied that the ox's bellowing would one day fill the world.
Legacy
Wrote the Summa Theologiae beginning in Rome in 1265, leaving it unfinished after a mystical vision in December 1273. He died at the Cistercian abbey of Fossanova on 7 March 1274, en route to the Second Council of Lyon.

The famous Eucharistic hymn containing the 'Tantum Ergo', composed for the Solemnity of Corpus Christi.
Read MoreGodhead here in hiding, whom I do adore, Masked by these bare shadows, shape and nothing more, See, Lord, at thy service low lies here a heart Lost, all lost in wonder at the God thou art.
Seeing, touching, tasting are in thee deceived: How says trusty hearing? that shall be believed; What God's Son has told me, take for truth I do; Truth himself speaks truly or there's nothing true.
On the cross thy godhead made no sign to men, Here thy very manhood steals from human ken: Both are my confession, both are my belief, And I pray the prayer of the dying thief.
I am not like Thomas, wounds I cannot see, But can plainly say that thou art God to me; This faith each day deeper be my holding of, Daily make me hope more, daily make me love.
O sacred banquet in which Christ is received, the memory of his Passion is renewed, the mind is filled with grace, and a pledge of future glory is given to us. Alleluia.
Creator of all things, true Source of light and wisdom, lofty origin of all being, graciously let a ray of Your brilliance penetrate into the darkness of my understanding and take from me the double darkness in which I have been born, an obscurity of both sin and ignorance.
Give me a sharp sense of understanding, a retentive memory, and the ability to grasp things correctly and fundamentally. Grant me the talent of being exact in my explanations, and the ability to express myself with thoroughness and charm. Point out the beginning, direct the progress, and help in completion; through Christ our Lord. Amen.
