Not really a surprise as Rome is considered the Holy city to Catholics.
I grew up Catholic and this is the first I've heard of a "holy city".
Weird concept.
I have always heard that from my Catholic friends. And-
Rome is the holy city to western Christianity because it became the seat of the Pope. Even Protestants tend to defer to Rome as a holy city. However,
Constantinople was regarded as the holy city of the Greek Orthodox Church because this was the seat of the Patriarch. In a similar style, the Greek Orthodox Patriarch of Jerusalem is known as the
Patriarch of the Holy City of Jerusalem, and indeed many Christians would regard Jerusalem as the holiest city in Christendom.
The Catholic Church asserts that the apostle Peter went to Rome, where he led the church as Rome's first bishop, appointing his successor there, but this claim is far from certain. Even at the end of the first century, the author of
1 Clement appears unaware that St. Peter ever came to Rome. Written from Rome, 1 Clement mentions Peter's 'many labours' and makes a general comment about Peter's death, without mentioning Rome: "There was Peter who by reason of unrighteous jealousy endured not one not one but many labours, and thus having borne his testimony went to his appointed place of glory." Rex Wyler, in
The Jesus Sayings, page 252, says the legend that Peter visited Rome appears in the non-canonical Acts of Peter, composed in about 185 CE.
Even in the absence of St. Peter in Rome, the city became the holy city of the Catholic Church because it was the centre of the Roman Empire, and thus the most powerful city on Earth. During the early years, the eastern Church had divided loyalties, between Constantinople, Jerusalem and Alexandria, whereas the entire Church in western Europe had Rome alone as its major centre, in turn giving the bishop of Rome considerable power and influence - in addition to the claim of Petrine succession. Nevertheless, Rome will never replace Jerusalem as the most holy city in Christendom.
Why is Rome the holy city?
The significance of
Rome lies primarily in the fact that it is the city of the pope. The
Bishop of Rome, as the successor of St. Peter, is the
Vicar of
Christ on earth and the visible head of the
Catholic Church.
Rome is consequently the centre of
unity in belief, the source of ecclesiastical jurisdiction and the seat of the supreme authority which can bind by its enactments the faithful throughout the world. The
Diocese of
Rome is known as the "See of Peter", the "Apostolic See" , the "Holy Roman Church " the "Holy See" -- titles which indicate its unique position in
Christendom and suggest the origin of its preeminence.
