Introduction to the Trinity Part 1: Our Trinitarian Faith

Sr. Mary Magdalene, O.P., is beginning a 12-part introductory series dedicated to the teaching of St. Thomas Aquinas on the Trinity. In Part 1, she gives an introduction to the topic of the Trinity and discusses the importance of our participation in the Trinitarian life, since simply to know something intellectually about what God has revealed concerning the Trinity is not enough. We must live it. That is, we must live a Trinitarian life.
