Theological Study: Eastern Catholic Churches

The fourth major branch of the eastern Christian churches (after the Church of the East, the Oriental Orthodox, and the Eastern Orthodox Church) are the Eastern Catholic Churches. These are basically churches that have reestablished union with the Roman Catholic Church. They were first part of the Catholic Church but then decided to separate after the Council of Ephesus, Council of Chalcedon, or the Great Schism of 1054. Throughout the history of these non-Catholic Eastern Churches there was often internal disputes that led to further schism. In this post I will study the Eastern Churches that broke away from their parent Orthodox Church to reunite with the Roman Catholic Church.  

The Roman Catholic church officially recognizes 23 Eastern Catholic Churches that are deemed "sui iuris" which means they are self-governing. However what makes these churches Catholic is that despite being independent they still recognize the authority of the Roman Pope (as opposed to most Orthodox churches). Nonetheless they are seen as somewhat bridge churches, between Eastern Orthodox and Roman Catholic. Despite submitting to papal authority they still maintain their Eastern Orthodox traditions. For example many of these churches still practice the divine liturgy, allow their clergy to marry, and put heavy emphasis on icons and monastic practice. This body of eastern Catholics make up 18 million of the 1.3 billion Catholics worldwide.

Theological Study: Churches of the Orthodox East

Continuing on with this Christian theological study that I just can't get enough of, I now turn to the Eastern Christian Churches. This will mark a slight pivot in direction from my strictly Catholic studies to cover the broader aspects of historical Christianity. I suppose it's also leaning into a deeper dive into the Euro-Asian region; the Byzantine Empire, Constantinople, and Tukey in general. This is of course in preparation to my trip to Istanbul there this fall. In retrospect I've been fascinated with this region since last fall when I first dove into studies on Vlad the Impaler and Mehmed the conqueror. Constantinople was once at the center of it all, and while the Christian Church was born in Jerusalem, it was truly developed in Turkey. 

This research of Eastern Orthodox Churches was especially inspired by my recent study of all the major ecumenical councils. I realized that the Eastern Churches were all once united at the first Nicaea Council in 325. Over time these churches broke off due to theological differences and mostly because of geopolitical ones. There are four main branches of Eastern Churches; The Church of the East (schismatic in 410 after the Council of Ephesus); the Oriental Orthodox Church (schismatic in 451 after Council of Chalcedon); the Eastern Orthodox Church (schismatic in 1054 during the Great Schism); and the Eastern Catholic Churches (established reunion with the Catholic Church, while still following their eastern liturgical traditions). In this post I'll focus on the three non-Catholic Eastern churches that are independent from the pope's authority. In the next post I'll cover the 23 eastern Catholic Churches that have reunited with Rome. 

Church of the East

The root development of the Church of the East began with Christian Communities in Mesopotamia and Persia what later became the Sasanian Persian Empire. By 410 they established the Church of the East at the Council of Seleucia. Their schism from the Roman Church occurred in 431 after the Council of Ephesus. The main reason for their break-up with the Catholic Church was over Christ's nature as divine and human. Cyril of Alexandria argued that Christ was one person who was equally divine and human, and that Mary was the Theotokos, mother of God. The Church of the East however supported Nestorius, Patriarch of Constantinople who argued that Christ was two persons with two natures (divine and human). He deemed Mary was the Christokos (mother of Christ) who gave birth to his human form, but not his divine form. This was the primary disagreement that led to the schism, but it is also understood to be contributed by political and cultural differences. The Church of the East was easily able to break-away from the Catholic Church, since they were based in the Persian Empire, outside Rome's jurisdiction. It became known as the Nestorian Church, even though Nestorius himself was exiled and finished his remaining years in monastic solitude.

This Church of the East developed a distinct form of Syriac liturgy quite different from the Greek and Latin traditions. They used the Aramaic language which was closely related to the language Jesus would have spoken. It's Eucharist service is known as the Liturgy of Addai and Mari (early Missionaries in Mesopotamia), is considered one of the oldest Christian liturgies still in use today. It has it's own liturgical calendar with a higher emphases on the Feast of the Epiphany as well Old Testament themes. It also uses a minimalist approach on church art and iconography similar to the Muslim religion, much different than the Catholic or even the Eastern Orthodox churches. The hierarchy structure begins with the Patriarch of the East, also known as the Catholicos. Then the Metropolitans who serve as archbishops, then bishops, and priests and deacons. It reached it's high point during the early Middle Ages with missionary work reaching as far as India and China.

The church has undergone several schisms throughout his history and today is one of the smallest of the Eastern Christian branches. The first major split was the Schism of 1552, where a dispute over patriarch led to a newly established branch in the east that reunited with the Catholic Church (known as the Chaldean Catholic Church). The Church of the East became known as the Assyrian Church of the East. A few years later in 1599 another branch break off in India to reunite with the Catholic Church known as the Syro-Malabar Church. In 1968 another schism occurred over the liturgical calendar and modernizing reform, which led to the development of the Ancient Church of the East. Both the Assyrian Church of the East and the Ancient Church of the east still operate today as the main branches of the Church of the East. Today they are based primarily in Iraq and spread throughout Iran, Syria, Turkey, and various other diaspora pockets across the globe with approximately 500,000 global members.


Oriental Orthodox Church

The 2nd major Schism from the Catholic Church occured at the Council of Chalcedon in 451. This continued the debate over the nature of the Christ that lead to the Nestorian Schism of 431. However this time it pertained to the relationship of those natures. The Chalcedon position was that Christ was one person with two distinct natures (divine and human). However the anti-Chalcedonians argued that Christ had one united nature that was fully divine and human, known as Miaphysitism. Once again this was mostly a debate over terminology, and the schism was most likely due to politics and cultural differences. The Anti-Chalcedonian movement was influenced by the teachings of St. Cyril of Alexandria and led by his successor, St. Dioscorus I of Alexandria who supported the phrase "one incarnate nature of God and the word" . The sect thus developed mostly in Egypt and spread into Syria, Armenia, and Ethiopia in what became known as the Oriental Orthodox Church.

The Coptic Orthodox Church became the mother church of the anti-Chalcedonian movement based in the booming intellectual city of Alexandria. This anti-Chalcedonian theology spread into Syria and Mesopotamia by St. Jacob Baradaeus to become the Syriac Orthodox Church. Similarly other branches developed in Armenia, Ethiopia, Eritrea, and India. These were not schisms, rather separate churches that developed in different regions, that shared the same theological beliefs as the mother Coptic Church of Alexandria. They were all in communion with one another and became the six main branches of the Oriental Orthodox Church. Unlike the Roman hierarchy system, this church does not have a central authority like the pope. Instead it governs itself independently, while still in accordance with the other Oriental Orthodox churches. This is a similar hierarchy structure as the Eastern Orthodox church, who ultimately reject papal authority.

The main 6 Oriental Orthodox churches all use different liturgical rites. The Coptic, Ethiopian and Eritrean follow the Alexandrian Rite; the Syriac and Malankara churches follow the West Syriac Rite; while the Armenian Apostolic Church follows the Armenian Rite. The mass services are known for more chants, incense, and longer services, sometimes ranging 2 to 3 hours (as opposed to the one hour of a Catholic Mass). They also use ancient languages in their liturgy such as Coptic, Ge'ez, Classic Syriac, and Armenian. The Oriental Orthodox church strongly encourages the practice of monasticism, inspired by the great Desert Fathers of Egypt such as St. Anthony the Great, St. Pachomius, and St. Macarius. The liturgical calender is also much busier than the Catholic church, with more feast days and longer fasting seasons. While the Coptic Church is often seen as the primary headquarters since it was the mother church, it still shares equal authority as the others. The Oriental Orthodox Church has approximately 60-70 million followers, with the vast majority being based in the Ethiopian Orthodox and Coptic Orthodox Church.


Eastern Orthodox Church

The Eastern Orthodox Church makes up the largest body of the Eastern Christian Churches. They were primarily based in Constantinople and stuck with the Roman Church throughout it's first 7 main Ecumenical Councils. During the controversial Council of Chalcedon that led to the Oriental Orthodox schism, the Roman church strengthened it's ties to Constantinople by granting them equal privileges. However Rome still saw itself as the central authority while Constantinople had now considered itself equal to Rome (especially since Constantinople had overtaken Rome as the new capital of the world). This led to tension and a power struggle long before the Great Schism of 1054. The tension reached new levels when Rome intervened on the Photian issue where the Byzantine emperor replaced a bishop with Photius. This caused a brief schism between Rome and Constantinople, who had now seen the Byzantine empire play a major influential role on the church in Constantinople. Despite the brief patch, the tension did not go away over the pope's authority over Constantinople. The final straw for Constantinople was when the Filioque (the Holy Spirit proceeding from the father and the son) became an official part of the Nicene Creed in 1014. Eastern theologians firmly disagreed with this concept since it was first introduced at the Third Council of Toledo (589). The official schism happened when the Patriarch of Constantinople closed all Latin churches and was quickly excommunicated by Rome in 1054. In response he also excommunicated the Pope and his papal legates.

There were also many other disputes that led to the Great Schism of East-West aside from papal authority and the Filioque. This included differences over liturgy (Greek vs Latin) as well as the Eucharist (leavened bread vs unleavened bread). They also favored married clergy vs celibacy. The East put more emphasis on mysticism, spirituality, and iconography. They also maintained closer ties with secular rulers, such as the Byzantine emperor, and considered themselves as the New Rome. This schism became all the more official when Roman crusaders captured Constantinople during the Fourth Crusade of 1204. This significantly splintered and weakened the Byzantine Empire who had already felt the pressure from the growing Arab Ottoman Empire. Nonetheless by 1261 they managed to recapture Constantinople, and the Eastern Orthodox continued to endure. Even after the Ottoman conquest they endured in monastic pockets throughout Euro-Asia and the Baltics. By the 1400s Russia had become the new central protector of the Eastern Orthodox Church. Although many attempts were made at reunion by the Catholic Church, the two eventually recognized one another as separate bodies.


The Eastern Orthodox Church considers itself the "rightful" continuation of the ancient church of the early fathers. The word Orthodox after all means the right or true belief (of course the Western Church would disagree with that title). For this reason it's liturgy (known as the Divine Liturgy) is much more traditional, ritualistic, and perhaps even a bit more extreme. The church service is fairly similar to the Roman church, however it's layout is very different. First it is heavy on iconography, most notably thru it's wall of icons known as the Iconostasis that separates the altar from the congregation. It also incorporates more chanting, repetition, heavy use of incense, longer services, and much more standing than Catholic masses. They put heavy emphasis on monastic traditions with more fasting, Mary as the Theotokos, and union with God (known as Theosis). It's hierarchal structure is not centralized the same way as the Roman Pope (this was after all the main dispute). There are 14 official Orthodox churches, each of which has their own authoritative patriarch. The Patriarch of Constantinople is considered the "first among equals", but this is only an honorary title for its foundational role. Mount Athos is considered one it's most holy sites of monastic worship. The Eastern Orthodox Church has approximately 220 million followers, the majority being from the Russian Orthodox Chuch.
