Dr. Marra joins to discussion with Fr. Gilsdorf. In this final installment Dr. William Marra closes with a discussion of Tradition, which was central to both Old and New Testament, and of the faulty notion in the modern world that Catholics feel they can read scripture without the guidance of the Catholic Church. Father Gilsdorf has shown how one must have holy scripture, sacred tradition and the magisterium. This recording is a summary of the previous nine talks and is a great aid in gathering together the many facts and arguments which were offered over the lecture series.
