This episode of "Catechism in a Year" podcast focuses on paragraphs 325-330 of the Catechism of the Catholic Church, specifically exploring the concept of "Heaven and Earth" and the existence of angels. Fr. Mike Schmitz explains that "Heaven and Earth" encompasses all of creation, both visible and invisible, and discusses the nature of angels as pure spirits with intelligence and will, serving as messengers of God. He emphasizes that angels are not human-like but are wholly devoted to God, contrasting this with the common misconceptions about angels. The episode concludes with a prayer and a reflection on humanity's unique position as both spiritual and corporeal beings, created to glorify God.
