St. Thomas Aquinas (1225-1274)
A student of St. Albert the Great, Thomas was a priest who taught theology in Paris. There he wrote his great work, Summa Theologica. He once experienced a divine revelation which so enraptured him that he abandoned the Summa, saying that it was nothing compared to the true Glory of God. He died a few months later, and was proclaimed a Doctor of the Church.

Reflections from the Saints

Grant me, O Lord my God, a mind to know you, a heart to seek you, wisdom to find you, conduct pleasing to you, faithful perseverance in waiting for you, and a hope of finally embracing you.
– St. Thomas Aquinas
