This monologue podcast episode of "Catechism in a Year" focuses on the language of faith within the Catholic Church. Fr. Mike Schmitz begins by explaining the importance of understanding faith not just as formulas but as realities that those formulas express, referencing St. Thomas Aquinas. He then discusses the Church's role in preserving and transmitting this faith across generations and cultures, quoting extensively from St. Irenaeus of Lyon. A key takeaway is the distinction between believing in the formulas of faith and believing in the realities those formulas represent; the episode emphasizes the necessity of both for a complete understanding of Catholic doctrine. The episode concludes with a reflection on the ongoing need for personal and communal renewal within the faith.
