Historian Axel Bayer says the legation was sent in response to two letters, one from the Emperor seeking assistance in arranging a common military campaign by the eastern and western empires against the Normans, and the other from Cerularius.
On the refusal of Cerularius to accept the demand, the leader of the legation, Cardinal Humbert of Silva Candida, O. B., excommunicated him, and in return Cerularius excommunicated Humbert and the other legates.
The bishops of Rome never obviously belonged to either the Antiochian or the Alexandrian schools of theology, and usually managed to steer a middle course between whatever extremes were being propounded by theologians of either school.
Because Rome was remote from the centres of Christianity in the eastern Mediterranean, it was frequently hoped its bishop would be more impartial.
Still, the Church split along doctrinal, theological, linguistic, political, and geographical lines, and the fundamental breach has never been healed, with each side sometimes accusing the other of having fallen into heresy and of having initiated the division.
The Crusades, the Massacre of the Latins in 1182, the West's retaliation in the Sacking of Thessalonica in 1185, the capture and Siege of Constantinople in 1204, and the imposition of Latin patriarchs made reconciliation more difficult.
While the church at Rome claimed a special authority over the other churches, the extant documents of that era yield "no clear-cut claims to, or recognition, of papal primacy." Towards the end of the 2nd century, Victor, the Bishop of Rome, attempted to resolve the Quartodeciman controversy.
Rome lost the Senate to Constantinople and lost its status and gravitas as imperial capital.Ultimately this is why his letters of excommunication came to no effect.Nevertheless it is possible to read in Eusebius' account the possibility that St.Earlier, in 494, Pope Gelasius I (492–496) wrote to Byzantine Emperor Anastasius, distinguishing the power of civil rulers from that of the bishops (called "priests" in the document), with the latter supreme in religious matters; he ended his letter with: "And if it is fitting that the hearts of the faithful should submit to all priests in general who properly administer divine affairs, how much the more is obedience due to the bishop of that see which the Most High ordained to be above all others, and which is consequently dutifully honoured by the devotion of the whole Church." In 330, Emperor Constantine moved the imperial capital to Byzantium, a strategically located city on the Bosporus.He renamed the capital Nova Roma ("New Rome"), but the city would become known as Constantinople.
