Why Does the Bishop of Rome Have Primacy?
How do we know that the bishops of Rome are meant to have the primacy of Peter?
Precisely because they are the successors of St. Peter, who traveled in his apostolic ministry and became the first bishop of Rome. For more on this subject, please see our presentation on the “Primacy of Rome,” which draws from the writings of the early Church Fathers. I also you refer to the late Fr. Ray Ryland’s article on the same subject.
