The Roman Catholic Church sees Peter as the first pope upon whom God had chosen to build His church (Matthew 16:18). It holds that he had authority (primacy) over the other apostles. The Roman Catholic Church maintains that so;metime after the recorded events of the book of Acts, the Apostle Peter became the first bishop of Rome, and that the Roman bishop was accepted by the early church as the central authority among all of the churches. It teaches that God passed Peter's apostolic authority to those who later filled his seat as bishop of Rome. This teaching that God passed on Peter's apostolic authority to the subsequent bishops is referred to as "apostolic succession."
The Roman Catholic Church also holds that Peter and the subsequent popes were and are infallible when addressing issues "ex cathedra," from their position and authority as pope. It teaches that this infallibility gives the pope the ability to guide the church without error. The Roman Catholic Church claims that it can trace an unbroken line of popes back to St. Peter, citing this as evidence that it is the true church, since, according to their interpretation of Matthew 16:18, Christ built His church upon Peter.
