The Perennial Baltimore Catechism, in response to Q. 499, explains that “The Pope, the Bishop of Rome, is the visible Head of the Church because he is the successor of St. Peter, whom Christ made the chief of the Apostles and the visible Head of the Church.”
As Catholics we know that people need to know truth (Jn 8:32; Jn 14:6; Jn 18:37) and that The Church is the Pillar of Truth, has authority, is visible, and is one (1 Tm 3:15; Mt 18:15-18; Jn 17:21) We also know, as Divinely revealed, that The the Pope is the Successor of St. Peter (The Church was built on St. Peter) (Mt 16:18 – 19)
In this Bible Study then we will clearly see the Divinely revealed Truth of the Authority of the visible Church, the Primacy of Peter (The first pope), passed on to his successors (successive popes), and the special charism of infallibility given to Peter and to those who eventually sit in his chair.
