Roman Catholic and Greek Orthodox believers both believe in the same God. 2. Roman Catholics deem the Pope as infallible, while Greek Orthodox believers don't. Roman Catholic priests cannot marry, while priests in the Greek Orthodox can marry before they are ordinated.
Subsequently, one may also ask, when was the Greek Orthodox Church founded?
At the time of the Schism of 1054 between Rome and Constantinople, the membership of the Eastern Orthodox Church was spread throughout the Middle East, the Balkans, and Russia, with its centre in Constantinople, which was also called “New Rome.”
Where was Greek Orthodox founded?
Two patriarchates are noted to have been founded by St Peter, the patriarchate of Rome and the patriarchate of Antioch. The Eastern churches accept Antioch as the church founded by St Peter (see the Greek Orthodox Church of Antioch and the Syriac Orthodox Church).
Who is the head of the Orthodox Church?
The Patriarch of Constantinople Bartholomew I is the spiritual leader of well over 250–300 million Orthodox Christians, though the Ecumenical Patriarch is not considered to be the head of the Eastern Orthodox Church. His official rank is primus inter pares (first among equals).
