This podcast episode delves into the formation of the Trinitarian dogma within the Catholic faith. Fr. Mike Schmitz guides listeners through paragraphs 249-252 of the Catechism of the Catholic Church, explaining the development of theological terminology (substance, person, hypostasis, relation) used to articulate the mystery of the Trinity. He uses the example of St. Augustine and a boy trying to empty the sea into a hole to illustrate the limitations of human understanding in grasping the infinite mystery of God. The episode emphasizes the importance of baptism in the Trinitarian formula ("in the name of the Father, and of the Son, and of the Holy Spirit") and concludes with a prayer to the Trinity.
