Did Roman Catholicism or Orthodox Catholicism come first? I want to know.
Neither . . . and both.
Please explain Deacon.
Until 1054, there was no difference. At the Great Schism, they split.
They were both founded by the direct 12 disciples of Jesus Christ.
I understand. Thank you Deacon. I’m discerning call to the diaconate, please pray for me. Much respect to you
What was the difference after 1054?
Although there was a split which recognized two churches, and since there can only be one true church, the Roman Catholic Church is that fullness of truth church, and the Orthodox Church split from the Roman Catholic Church.
While many of the particular Churches that are now numbered as Eastern Orthodox Churches are of ancient origin, at various points in history they separated from the one holy, catholic, and apostolic Church we profess in the Creed. This Church as part of its divine constitution retains one particular Church in primacy, fixed like a rock (which is Rome, by virtue of Peter’s primacy among other things). The particular Church of Rome cannot separate from the one catholic Church we profess in the Creed.
It also bears pointing out that certain Eastern Orthodox Churches are in schism with one another right now–so they can’t even be said to be one catholic Church at all currently (and at other various points in their histories). The Catholic Church in communion with the Church of Rome has always retained the four marks in the Creed.
