"To one who has faith, no explanation is necessary. To one without faith, no explanation is possible."
-- St. Thomas Aquinas, 13th Century Dominican priest, monk, philosopher, theologian, university professor and Doctor of the Church. St. Thomas is considered by many one of the greatest scholars in Catholic Church history. He was an ardent seeker of truth and the foremost proponent of natural theology, which conforms faith and reason. He was so influential that, eight centuries after his death, his writings and contributions, known as "Thomism," are still studied in seminaries across the world today. He is best known for his Summa Theologiae, which is an comprehensive and systematic explanation of Catholic theology, that he never finished. He died in his late 40's in 1274.
