Saint Thomas Aquinas OP was a Dominican friar, priest, and Doctor of the Church. He was an immensely influential philosopher, theologian, and jurist in the tradition of scholasticism, within which he is also known as the “Angelic Doctor”
He was the foremost classical proponent of natural theology and the father of Thomism; of which he argued that reason is found in God. His influence on Western thought is considerable, and much of modern philosophy developed or opposed his ideas, particularly in the areas of ethics, natural law, metaphysics, and political theory. Unlike many currents in the Church of the time,Thomas embraced several ideas put forward by Aristotle—whom he called “the Philosopher”—and attempted to synthesize Aristotelian philosophy with the principles of Christianity.The works for which he is best known are the Summa Theologiae and the Summa contra Gentiles. His commentaries on Scripture and on Aristotle form an important part of his body of work. Furthermore, Thomas is distinguished for his eucharistic hymns, which form a part of the Church’s liturgy.
Pope Benedict XVI had said: “This (Dominican) Order … acquired new luster when the Church declared the teaching of Thomas to be her own and that Doctor, honored with the special praises of the Pontiffs, the master and patron of Catholic schools.”
