In the third episode of "Catechism in a Year," the hosts dive into the first pillar of the Catechism: "What We Believe," also known as the Creed. They break down the structure of the Catechism, which consists of four key pillars: beliefs, worship, life, and prayer. This framework isn't just a collection of information; it serves as a pathway to deepening our relationship with God. Jeff Cavins draws an interesting parallel with the film "The Truman Show," using it to illustrate how God reveals Himself to us. The episode wraps up with an important reminder: believing in the Creed goes beyond just agreeing intellectually; it calls for a personal commitment to God that leads to real transformation. To enrich their understanding, listeners are encouraged to refer to a reading plan and use a physical Catechism.
