“roman” Catholic is a term never used before the Great Schism in 1054ad.
I never said the term Roman Catholic was not used before 1054. I was talking about the divergence of the early church into the Latin Roman church and the Greek Orthodox church which was a long drawn out process culminating in the Great Schism.
Prior to the Great Schism, there were 5 Apostolic Patriarchates...Rome, Constantinople, Alexandria, Antioch, and Jerusalem. Each Patriarch/Pope was considered equal. But the Pope of Rome wanted to be the “first amongst equals”. The other 4 Patriarchs were not pleased with that arrangement. The churches split into the Roman/Western Catholic Church, while the other 4 patriarchates became what is considered the Eastern (Orthodox) Church.
