Saint Thomas Aquinas, OP

Thomas Aquinas was an Italian Dominican friar and priest, theologian, and philosopher. He is considered one of the most influential thinkers in the history of Catholic theology and Western philosophy. Thomas was a proponent of natural theology and the father of a school of thought known as Thomism. He argued that God is the source of the light of natural reason and the light of faith. He embraced several ideas put forward by Aristotle and sought to synthesize Aristotelian philosophy with the principles of Christianity. Among his best-known ideas include his Five Ways for proving the existence of God, his virtue ethics, and his sacramental theology. Thomas's best-known work is the unfinished Summa Theologica, which is a comprehensive guide to the theology of the Catholic Church. His body of work also includes the Summa contra Gentiles and numerous commentaries on Christian Scripture and on Aristotle. Thomas has been described as "the most influential thinker of the medieval period" and is generally considered to be one of the Catholic Church's greatest theologians and philosophers.
