Communication was poor in those days, and when one pope died, by the time the word got out, Orthodox had chosen their pope, and Romans had chosen their pope. There cannot be two popes, and neither side would agree that the other side's pope was chosen by God.
The two churches were the Eastern Orthodox and the Roman Catholic
1054
No, the Roman Empire had fallen about 600 years prior to the Great Schism.
The two Christian churches that developed after the split in 1054 are the Roman Catholic Church, based in Rome and headed by the Pope, and the Eastern Orthodox Church, which has its headquarters in Constantinople (modern-day Istanbul) and is led by various patriarchs.
The Great Schism was between the Roman Catholic Church and the Eastern Orthodox Church (or Catholicism and Eastern Orthodox).
If you are talking about the split when the Eastern Rites split into two with half remaining with the Church, and half forming the Orthodox Churches, I don't think it is permanent, just very long lasting.
Catholics will say that the Orthodox church split from the Catholic Church. Orthodox will say that the Catholic Church split from the Orthodox church. But yes, the two churches did split from one another.
The oriental orthodox,eastern orthodox and roman catholic churches all started when various apostles spread mainly the middle east and eastern Europe. Soon the churches started to split the oriental orthodox then eastern orthodox and catholics together. Its hard to say when oriental orthodox started because it consists of several apostolic churches in communion which each other all founded at different times by different apostles
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.
Yes, Saint George is recognized as a Christian saint by the Eastern Orthodox Church. He is considered one of the most prominent military saints and is venerated in both the Eastern Orthodox and Western Christian traditions.
They were not. Both the Orthodox and Roman Catholics accept the decision of the Seventh Ecumenical Council which declared that the veneration of icons is essential in the Christian Church. The split (or schism) was due to other causes, such as Papal claims of supremacy, and the change to the Creed.
Christianity can be divided into three parts: the Roman Catholic Church, the Eastern Orthodox Church, and Protestantism. The Roman Catholic Church and Eastern Orthodox Church split in the 11th Century. Protestantism was born from Reformation in the 16th Century and split from the Roman Catholic Church at that time.
