Mr Rogers:
There was a Roman Catholic Church in 200 AD. There was also a Catholic Church in Antioch, Alexandria, and other major cities in the Mediterranean part of the Roman Empire. Of course, given your name is “Rogers” there was no such thing as Christianity in the places where American Protestants ancestors came from, such as Scotland, Wales, England, and Scandinavia.
There was a Church at Rome going back to the earliest days of Christianity. St. Paul preached in my Ancestral homeland of Sicily as well. Saint Ignatius of Antioch in circa 107 AD speaks of the Catholic Church and he clearly indicates there was a Church at Rome that presided in Love and mentions Saints Peter and Paul as being part of the Church of Rome.
It is more accurate to say there were no such things as Baptist, Pentecostal, Church of Church, Presbyterian churches at that time.
The Muratorian Fragment [written around 180AD], which the Protestant Scholar cites was compiled by the Church of Rome probably after the time during the time Pope Pius when he was Bishop of Rome [140 to 155 AD] as it mentions the Shepherd of Hermas as being written during that period.
The Church at Rome was Catholic and always has been since its inception.
“There was a Roman Catholic Church in 200 AD.”
No. There was not a church that taught what the Roman Catholic Church teaches. Even past 400 AD, the “Pope” was not thought of as Pope. Shoot, arguably the Orthodox have the real claim to continuity, with the Roman Catholics breaking off to follow their earthly leader.
