The Churches that came out of the Great Schism of 1054 both claimed to be the original Christian Church. One was the Roman Catholic Church and the other was the Orthodox Church, although this is a more general term for a group of Churches with more than one Patriarch.

They were mostly Christian, and after 1054, split from the catholic, or universal church, and are usually referred to as "Greek Orthodox."
The Catholic Church and the Orthodox Churches split during the schism in 1054.
The Byzantine form of Christianity was eventually called Orthodox. In 1056, the Roman and Byzantine churches split over a number of doctrinal controversies.
The Great Schism was between the Roman Catholic Church and the Eastern Orthodox Church (or Catholicism and Eastern Orthodox).
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.
The East-West Schism of 1054 sometimes known as the Schism of the East.
