In this program, Dennis Wholey has a conversation about Roman Catholicism with Cardinal William H. Keeler, Archbishop of Baltimore. Topics of discussion include who Jesus Christ is, from a Catholic perspective; the concept of the Trinity; the seven sacraments; the purpose and meaning of the Mass; what makes a Catholic a Catholic; and the effect of cultural secularization on the Church. In addition, the history of the restored Baltimore Basilica—America’s first cathedral and the foundation of Roman Catholicism in the U.S.—is outlined by Mark J. Potter, executive director of the Basilica Historic Trust. (27 minutes)
