Nicknames for St. Thomas Aquinas include the “Dumb Ox” and the Doctor Angelicus.

Thomas Aquinas (1224 approx - 1274) is considered as one of the Catholic Church's greatest theologians and philosophers, that is still regarded as a model for priesthood studies.

He was named Doctor Angelicus since he was seen as an angel that came to Earth in order to share knowledge of the Church; for his great purity when he dealt with sexual issues like temptation, for having been an expert at teaching about angels, for his wisdom in seeing the essential unity of all theology in God,  for being a guardian and guide for the schools and systems of theology, and the like.
