The Great Schism was between the Roman Catholic Church and the Eastern Orthodox Church (or Catholicism and Eastern Orthodox).
In 1054, due to political problems, most of the Eastern Rites of the Church split in two, half of them remaining with the Church, and half of them forming the Orthodox Churches.
I assume you mean the official split into Eastern Orthodoxy and Roman Catholicism, which happened in 1054.
Christianity split into Catholicism & Orthodoxy.
Roman Catholicism
The Orthodox Church as it is today was established at the Great Schism of 1054, when Christianity split into the East (Eastern Orthodoxy) and the West (Roman Catholicism).
1054
The Eastern Orthodox faith was established in 1054 with the Great Schism. At this time, the East split from the West and established two churches: Eastern Orthodoxy and Roman Catholicism.
The East-West Schism of 1054 sometimes known as the Schism of the East.
The Roman Catholic Church and the Eastern Orthodox Church.
1054 is MLIV in Roman numerals.
In 1054, the Great Schism occurred in Christianity, leading to the separation of the Eastern Orthodox Church and the Roman Catholic Church. This schism was largely over theological, cultural, and political differences between the two branches of Christianity. It marked a permanent split in the Christian faith, with lasting implications for the religious landscape of Europe and the Middle East.
A:The Roman Catholic Church and the Orthodox faith were formed out of the Great Schism of 1054, although the split was not really regarded as permanent until much later.
In 1054 Christ's which (except for small groups of heretics and the Oriental Orthodox) was generally undivided and truly one split into the Roman Catholic Church and the Eastern Orthodox Church. The Orthodox would see the division this way: before 1054 there was just the Orthodox Church. After 1054 there was the Orthodox Church and the heretical church of the Patriarch of Rome, which would eventually call itself the Roman Catholic Church. The Romans would say that prior to 1054 there was just the Roman Catholic Church and then the Orthodox split off becoming a separate church. The way I, an Anglo Catholic, see it was that they both split from each other creating the Roman Catholic and Eastern Orthodox churches. Neither church really existed as a separate denomination before. The denominational terms came into existence because of the tragic split.
