The Classical Theism Podcast aims to defend Catholic Christian ideas in conversation. With the help of various guests, I defend three pillars of the Catholic Christian worldview: (1) the God of classical theism exists, (2) Jesus is our Messiah and Lord, and (3) He founded the Catholic Church. We place a strong emphasis on the first pillar, defending classical theism, drawing upon the work of Thomistic philosopher Dr. Edward Feser and many others. Thanks for listening!
