You're a little confused, which is understandable, but there is no "Roman Catholic", that is a misnomer from the time of the protestant revolt, which has become so popular in English that even some Catholics use it, but it is intended as a slur. The Catholic Church was established by Jesus Christ from the cross, and shown to the world at Pentecost. Despite many difficulties over the centuries, the Church was always one, up until the 11th century, when the Orthodox churches no longer paid allegiance to the Pope in Rome. After this time, all of the Orthodox national churches split, and part remained with Rome, and part separated due to national interests, thus there is not the Greek Orthodox Church and the Greek Uniate Church, the later looks exactly the same but is in union with Rome. For a thorough discussion of the issues involved and why they separated, please see Vladimir Soloviev's book The Russian Church and the Papacy. Soloviev discusses all the Orthodox churches and the reasons for the split in his book, as he was raised in the Russian Orthodox Church he has an insider's view on what went on. See the link below.
Constantinople was given the titles of "the new, second New Rome," "Alma Roma", "Eastern Rome" and "Roma Constantinopolitana."
The emperor Constantine I (or the Great) did not move the imperial capital of the roman Empire from Rome to Byzantium. He moved the imperial capital of the eastern part of the Roman Empire from Nicomedia (in north-western Turkey) to the nearby Byzantium, which he redeveloped and renamed after himself -- Constantinople (City of Constantine). Milan remained the imperial capital of the western part of the empire.Nicomedia and Milan had been designated as the imperial capitals of the east and west respectively by the emperor Diocletian. Rome had already ceased to be the imperial capital before Constantine.

Rome was too far from the frontiers. Constantinople provided easy trade and military access to the Mediterranean, Black Sea, Danube River, Dnieper River, and the land route to Turkestan and India.

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.
