This podcast episode of "Catechism in a Year" focuses on explaining the concept of the Trinity's involvement in God's divine plan (the "divine economy"). Fr. Mike Schmitz explains that the Father, Son, and Holy Spirit work together in creation, salvation, and sanctification, with each person having unique roles yet remaining united. He highlights the Second Council of Constantinople's statement: "one God and Father from whom all things are, one Lord Jesus Christ through whom all things are, and one Holy Spirit in whom all things are." The episode concludes with a prayer by Blessed Elizabeth of the Trinity, emphasizing the desire to be fully established in the unity of the Trinity. Listeners gain a deeper understanding of the Trinity's interconnected roles in God's plan and their own relationship with the divine.
