Introduction to Thomas Aquinas

This course introduces the student to St. Thomas Aquinas— philosopher, theologian, sacred poet, and member of the Dominican order, a friar who sought his salvation as a priest under the vows of poverty, chastity, and obedience, but who also possessed one of the greatest philosophical minds of history. The writings of St. Thomas have shaped Catholic thought since his death up to our own day.
