This episode of "Catechism in a Year" podcast focuses on explaining the nature of Jesus Christ as both true God and true man. Fr. Mike Schmitz discusses several early Christian heresies that challenged this doctrine, including Docetism, Nestorianism, and Monophysitism, highlighting the Church councils that addressed these challenges and clarified the orthodox understanding. He emphasizes that Jesus is one divine person with two natures (divine and human), without confusion or separation, a crucial point for understanding salvation and the Incarnation. The episode concludes by reiterating the importance of understanding this complex theological concept to strengthen faith and effectively communicate Christian beliefs. The Council of Chalcedon's declaration that Jesus is "perfect in divinity and perfect in humanity" is presented as a key takeaway.
