St Methodius and St Cyril.
it was based on the New Testament church founded by Jesus Christ in 33 AD. From there, the church spread to all parts of the world until the year 1054 AD, when there was a split or schism and this caused the two groups to be known as Roman Catholic and Eastern Orthodox from that period onwards.
When Christianity spread around the Roman Empire it developed two main churches; Eastern part Greek and Western or Latin. The former was the main church in the eastern part of the empire and the latter the main one in the western part. Later they came to be called Orthodox and Catholic respectively.
The Byzantines spread Orthodox Christianity to those areas.
The orthodox countries are: Russia, Ukraine, Serbia, Montenegro, Bulgaria, F.Y.R Macedonia, Greece, Cyprus, Romania, Georgia, Armenia, Bosnia and Herzegovina, Belarus, Kazakhstan and Moldova. - UPDATE - However there are Orthodox Churches and Orthodox followers in almost every country around the world.
They spread of Orthodox Christianity (the religion of this empire) to Eastern Europe. The missionaries Cyril and Methodius developed the Slavonic alphabet so that the Slavs could read the bible. They created an architectonic style for church buildings which inspired the design of Orthodox Churches in Eastern Europe. They preserved the written works of the ancient Greeks.
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
The Byzantines spread Orthodox Christianity to those areas.
Which Greeks would that be? The high point of Greek civilization predates Christianity, but Christianity began its spread in the Greek-speaking parts of the Roman Empire. However, at the time the Church was becoming organised, the Catholi (that is, Universal) Church split into Eastern and Western sections; the Western, based in Rome, became the Roman Catholic Church; the Eastern, based in Byzantium/Constantinople, is now the Greek Orthodox Church. So the answer, in brief, is - No.
The Eastern Orthodox (EO) Church was begun in Constantinople (Istanbul, Turkey) by Constantine of Rome. He ordered that Rome's Religion be changed from paganism to Christianity (at the time there was only gonna be one) He gathered the numerous churches (i.e. Greek, Palestinean, Egyptian, Roman) and sat them down to form the new church traditions. This then became the Orthodox Church. This all occured around 350 AD. Around 1032 AD the Western Churches, (Rome, France, Spain) united and split from the Orthodox church to form a church with one head king. While the orthodox churches each had a king who met in a religious council to decide issues (religious republic). The new church in the west was eventually called the Holy See or Holy Catholic Church. Today Eastern Orthodoxy has spread and incorperated new churches like Brazil, Ethiopia, Kenya, Turkey, Russian, and more. The largest of which is Russian and today Constantiniple (Istanbul)is still the center of the eastern faith.
There have been monks and nuns in the Orthodox Church from as early as the Third Century AD. Since then, Orthodoxy has maintained a strong monastic presence in most countries, but particularly in Greece, Russia and Serbia. In recent decades, Orthodox monasticism has spread to countries such as the USA, Canada, Britain and Australia, with many monks and nuns coming from former Catholic and Protestant backgrounds. One particular monastery in the US today, in Arizona, has over 40 monks, most of whom are former Protestants. Even many African Americans are discovering the richness of the Orthodox Faith, and have established the St Moses the Black Orthodox brotherhood. The Orthodox Church regards monasteries as being the 'lungs' of the Church, and therefore an essential part of the faith.
The Roman Empire was the geographical factor which first helped the spread of Christianity. It started in Judea, which was part of the Roman Empire. It was spread through this empire, especially its eastern part by Christian preachers. Originally the Christians were Jews who preached other Jews and followed Jewish law. Paul created a theology which opened Christianity to the gentiles (non-Jews) of the Roman Empire. He said that faith in Jesus and following his teaching was what was required for salvation. Therefore, you did not have to be a Jew or follow Jewish law to be a Christian. Christianity was endorsed by all but one of the emperors after Constantine the Great. This helped his spread. The co-emperors Gratian and Theodosius made mainstream Christianity (the Latin/Western Church and the Greek/eastern Church, which later came to be called Catholic and Orthodox respectively) the sole legitimate religion of the empire.
The patriarchal cross is a symbol that represents the authority and leadership of the Christian church. It is often associated with the Eastern Orthodox and Eastern Catholic churches, and is seen as a symbol of the spiritual and temporal power of the church's leaders. The cross has two horizontal bars, with the top bar representing the inscription that was placed on Jesus' cross, and the bottom bar representing the footrest. The patriarchal cross is a reminder of the sacrifice and teachings of Jesus Christ, and the responsibility of church leaders to uphold and spread those teachings.
