The series has the same premise as Fr. Longenecker’s well-known book of the same name. Using C.S. Lewis’ Mere Christianity as a starting point, Father tells listeners why the fullness of the Christian Faith can only be found in the Catholic Church. Father challenges all listeners to go further up and deeper into the topics that often arise in Catholic/Protestant discussions. Over the course of any month, Father will interview converts to the Catholic faith, impart the stories of saints, and interview Catholics devoted to them. Fr. Longenecker will also talk to experts in Catholic culture–literature, art, architecture, music and movies. In other episodes, he’ll be interviewing Catholics involved in social issues and there will be special episodes on the supernatural aspects of the Catholic faith.
