Thomas Aquinas

Born c. 1225 near Roccasecca in southern Italy, Thomas Aquinas was a Dominican friar and the greatest theologian-philosopher of the medieval period. In his magnum opus Summa Theologica he systematically integrated Aristotelian philosophy with Christian theology, representing the summit of Scholasticism. His Five Ways for demonstrating God's existence and his natural-law theory remain foundational in Catholic thought. He holds the title Doctor Angelicus (Angelic Doctor) of the Church.
