The main body of the Church was split into a eastern and western parts in the Great Schism in 1054. There were other, lesser, schisms, and there were always independent branches of the Church that did not look to Rome, or Constantinople, for leadership, but the large majority of Christians were part of the Church that divided.

The capital of the Roman empire was Rome and later Ravinia, in the West. In the East it was Constantinople.
Eastern Rome was Rome and western Rome was Constantinople
Constantine patterned the city of Constantinople after Rome.
Because the capital of the Roman Empire was transferred from Rome to Constantinople in 330 AD.
The catholic church was never moved to constantinople, emperor constatine kept the church in Rome but moved the capitol to Constantinople. The SPRQ's belief of the church for salvation and emotional comfort kept the eastern empire alive for as long as it did, though it ultimately fell.

Both Rome and Constantinople had written laws. Emperor Justinian of Constantinople wrote the Corpus Julius Civilius which was based off the Roman written codes. Also Rome and Constantinople both practiced Christianity. Although Rome followed the Roman Catholicism and Constantinople followed the Eastern Orthodox Church, these are still from the same roots of the belief of Christianity. Also the idea of domes were used by both Rome and Constantinople. Rome had built the "Pantheon" and Constantinople built the Hagia Sophia. Emperor Justinian of Constantinople built the domes even bigger by using the quadrangle underneath the domes. Also both Rome and Constantinople were involved in trade and cultural diffusion with other countries.
The western church became known as the Roman Catholic Church after the Great Schism of 1054. This schism divided Christianity into two branches: the Western Church, led by the Pope in Rome, and the Eastern Church, known as the Orthodox Church, headed by the Patriarchs of Constantinople.

Most medieval Christians were Catholic and the head of the Catholic Church was the Pope. Popes were usually located in Rome, but there were times when they were in residence elsewhere. The head of the Eastern Orthodox Church, which was divided from the Roman Catholic Church in 1054, was in Constantinople. There were other church sects but they were much smaller.
Constantinople was based on the Christian religion and Rome was against it.
The Roman Empire divided into the Western and Eastern, with the West centered in Rome, and the East centered in Constantinople, if you are talking about the Eastern Schism. The Great Schism in the Catholic Church usually refers to the Western Schism which divided European countries over who the true Pope was.
This is the name given to the Eastern Orthodox Church where the Ecumenical Patriarch resides in Constantinople (present-day Istanbul, Turkey). It is the church founded by St Andrew the Apostle, and was the Cathedral Church during the Eastern Roman or Byzantine Empire. It is similar to saying the papal church of Rome where the Pope resides. The Ecumenical Patriarch in Constantinople is known as the 'first among equals' in the Orthodox Church.
Since Rome was then the HQ of the Church of the West, and Constantinople has fallen to the Turks, The Orthodox Church found it suitable to reassign Moscow as The Center of Orthodoxy Christianity, there fore being the "Third Rome."
Constantinople was approximately 800 miles east from Rome.
