This course takes an in-depth look at the theological vision of the two most influential Catholic theologians of the second Christian millennium: St. Thomas Aquinas and Pope John Paul II. The main features of St. Thomas's synthesis of Christian thought, especially as found in his great Summa Theologiae, is explored. This is followed by an examination of the personalist Thomism of Pope John Paul II, and his program for the renewal of the Catholic Faith, especially as found in selected encyclicals and apostolic letters. The vision and worldview of St. Thomas Aquinas and John Paul II are presented as significant and enduring achievements of Christian thought.
