When we recite the creeds that claim a belief in the “holy catholic church” and the “holy catholic faith” we do not mean the Roman Catholic Church or the Roman Catholic faith. Indeed, all of the Reformers taught that Rome had abandoned the catholic faith on their view of authority, Scripture, Mary, justification, the Lord’s Supper, church government, officers, prayer, the dead, sola Scriptura, sola fide, sola gratia, solus Christus, and other things. If the Reformers were right, then Rome does not have the right to use the term “catholic" and cannot truthfully confess the ecumenical creeds that affirm belief in a catholic church and a catholic faith. This sermon exams the counter-claims of both sides and concludes that the Reformers were correct. It demonstrates how the early church fathers would likely have characterized the modern Roman Catholic Church as the “ Roman Gnostic Church and as a cult that had left the catholic faith. The Protestant reformers were the true catholics who were defending the “faith once for all delivered to the saints” and defending the “common salvation” spoken of in Jude 3.
