The Greek Orthodox Patriarchate of Alexandria and All Africa (), also known as the Greek Orthodox Church of Alexandria, is an autocephalous Eastern Orthodox church based in Africa. Its seat is in Alexandria, Egypt, and it has canonical jurisdiction over the entire African continent.

According to Eastern Orthodox tradition, the Greek Orthodox Church of Alexandria was established by Saint Mark the Evangelist, a companion of the Apostles, in the middle of the 1st century, and its emblem is the Lion of Saint Mark. In the history of early Christianity, the Church of Alexandria played a significant role, and many prominent Church Fathers were associated with Alexandria. Following the Council of Chalcedon in 451, disagreements over the nature of Christ led to a division between Dyophysite and Miaphysite Christians. The Dyophysite Christians in Egypt remained in communion with the Ecumenical Patriarchate of Constantinople and developed into the Greek Orthodox Patriarchate of Alexandria, while the Miaphysite Christians formed the Coptic Orthodox Church of Alexandria.

Together with the other four Chalcedonian patriarchates, the see of Alexandria formed part of the traditional Pentarchy of the early Christian Church. Following the East–West Schism in 1054, the Greek Orthodox Patriarchate of Alexandria remained in communion with the Ecumenical Patriarchate of Constantinople and the other Eastern Orthodox churches.

Over the centuries, the patriarchate's influence and the size of its Christian community declined significantly, particularly after the Arab conquest of Egypt and later historical developments. In the 20th and 21st centuries, however, the patriarchate experienced renewed growth through missionary activity, especially in sub-Saharan Africa, establishing new dioceses and attracting new Eastern Orthodox communities across the continent.

The patriarchate is headed by the pope and patriarch of Alexandria and All Africa, currently Theodore II of Alexandria, who has served as patriarch since 2004.

History Origins The city of Alexandria was the capital of Roman Egypt and one of the largest and most influential cities of the Roman Empire, distinguished by its cosmopolitan population, including Greeks, Egyptians, and a substantial Jewish community.

The history of the Patriarchate of Alexandria is closely linked with the development of early Christianity and includes some of the most influential figures among the Church Fathers, particularly Athanasius and Cyril, who played decisive roles at the ecumenical councils of Nicaea (325) and Ephesus (431), respectively.

According to ecclesiastical tradition, Mark the Evangelist founded the Church of Alexandria around AD 43, having been sent by the apostles Peter and Paul during the reign of the emperor Claudius.

Later traditions indicate that Mark traveled to Rome and northern Italy before returning to Alexandria, where he was eventually martyred, possibly during anti-Christian unrest. According to Eusebius of Caesarea and later hagiographical traditions, his death involved being dragged through the streets of the city.

The earliest Christian converts in Egypt were primarily drawn from the Hellenized Jewish population of Alexandria. However, Christianity rapidly expanded among the native Egyptian population, particularly in the Nile Valley. Evidence of this early expansion includes papyri from Oxyrhynchus (Bahnasa), as well as early Coptic translations of the Gospel of John, which date to the 2nd century.

The growth of Christianity in Egypt was influenced by broader social and political conditions. Roman administration, established after the conquest of Egypt in 30 BC, imposed a highly centralized system of taxation and governance that placed significant burdens on the local population.

Within this context, Christianity offered both a religious alternative and a framework for communal identity that transcended ethnic and social divisions. By the end of the 2nd century, Christian communities were firmly established throughout Egypt.

The symbol of the cross began to gain prominence among Alexandrian Christians, particularly within the emerging Coptic tradition. Earlier symbolic forms, such as the Chi Rho, were also used, especially in imperial contexts associated with Constantine the Great.

Development Alexandria rapidly became one of the most important intellectual centers of early Christianity. The Catechetical School of Alexandria emerged as a leading institution for theological education, attracting scholars from across the Mediterranean world.

Among its most prominent teachers were Clement of Alexandria and Origen, whose writings had a profound influence on Christian theology. Origen, in particular, developed an allegorical method of scriptural interpretation and contributed significantly to early doctrinal formulation.

At the same time, Alexandria became a center for diverse theological movements. Gnostic teachers such as Basilides, Carpocrates, and Valentinus were active in the city, presenting alternative interpretations of Christian doctrine. These teachings were opposed by church authorities, who sought to define orthodoxy and maintain doctrinal unity.

Monasticism also developed in Egypt during this period and became one of the defining features of Alexandrian Christianity. Figures such as Anthony the Great and Pachomius established models of ascetic life that spread throughout the Christian world.

During the episcopate of Heraclas (231–248), the bishops of Alexandria adopted the title "Pope" (Greek: pappas), reflecting their growing authority within the Christian world.

The 4th century was marked by the Arian controversy, initiated by the Alexandrian presbyter Arius, who argued that the Son was subordinate to the Father. This teaching was condemned at the Council of Nicaea (325), convened by Constantine the Great.

Athanasius of Alexandria emerged as a central defender of Nicene orthodoxy and played a crucial role in shaping Trinitarian doctrine. His repeated exiles during the controversy reflect the political as well as theological dimensions of the conflict.

Alexandria’s influence extended beyond Egypt. In the 4th century, Christianity was established in the Kingdom of Aksum (modern Ethiopia and Eritrea) under the leadership of Frumentius, who was consecrated bishop by Athanasius.

Schism and late antiquity

The 5th century brought profound theological divisions within the Christian world. The Council of Chalcedon (451) defined Christ as having two natures, divine and human, in one person. This definition was rejected by many Christians in Egypt, who adhered to Miaphysite theology.

The refusal of Patriarch Dioscorus I of Alexandria to accept Chalcedonian doctrine led to his deposition and the establishment of a rival patriarch. As a result, the Church of Alexandria split into two parallel hierarchies:

The majority, composed largely of native Egyptians (Copts), formed what became known as the Coptic Orthodox Church. A minority, primarily Greek-speaking and aligned with imperial authority, formed the Chalcedonian (Greek Orthodox) Patriarchate of Alexandria.

These Chalcedonian Christians were often called "Melkites", a term derived from the Semitic word for "king", indicating their loyalty to the Byzantine emperor.

The division had profound social, cultural, and political consequences, reinforcing distinctions between the Greek-speaking elite and the Egyptian population. Over time, the Coptic Church became closely associated with Egyptian identity.

During the 6th and early 7th centuries, tensions between Chalcedonian and non-Chalcedonian communities were exacerbated by imperial policies, including attempts by emperors such as Justinian I to enforce doctrinal unity.

Persian and Arab conquest

In 619, Egypt was conquered by the Sasanian Empire, an event that disrupted Byzantine control and weakened the position of the Chalcedonian Church.

Although Byzantine rule was briefly restored, the region was soon conquered by Arab Muslim forces between 639 and 642.

The Arab conquest marked a turning point in the history of Christianity in Egypt. The Chalcedonian patriarch, closely associated with Byzantine authority, lost political support, while the Coptic Church, which had been marginalized under Byzantine rule, was relatively better positioned under the new administration.

Under Islamic rule, Christians were recognized as dhimmi communities and were allowed to practice their religion in exchange for paying the jizya tax. However, over time, the Greek Orthodox community declined significantly in both numbers and influence.

By the early 7th century, only about 300,000 of Egypt’s six million inhabitants belonged to the Greek Orthodox Church, while the majority adhered to the Coptic Church.

During the early Islamic period, the Greek patriarchate experienced a prolonged interruption, and its institutional structure weakened considerably. Many churches passed into the hands of the Coptic community.

Medieval period

From the 8th to the 15th centuries, the Greek Orthodox Patriarchate of Alexandria remained a small community with limited influence. Its leadership was often influenced by the Ecumenical Patriarchate of Constantinople, reflecting dependence on the Byzantine ecclesiastical world.

Despite the formal break between Eastern and Western Christianity in the East–West Schism of 1054, relations between Alexandria and Rome did not immediately cease. Contacts continued during the Crusades, when cooperation between Greek and Latin Christians was occasionally necessary. At times, Greek patriarchs permitted Latin clergy to minister to their communities, and Alexandrian representatives participated in broader ecclesiastical councils. However, tensions increased following the establishment of Latin patriarchates in the East.

Attempts at reunification, particularly at the Council of Florence (1439), were ultimately unsuccessful, especially after the fall of Constantinople in 1453, which further isolated the Alexandrian Patriarchate from both Western and Byzantine support.

During the 13th–14th centuries, most Patriarchs of Alexandria were of Greek origin. Many of them resided in Constantinople for extended periods and only rarely appeared in Egypt, while actively participating in the ecclesiastical life of Byzantium. The Alexandrian Church possessed almost no independent sources of income in Egypt and therefore remained in a chronically difficult financial situation, relying primarily on support from other Eastern patriarchs and assistance from Orthodox states.

The number of followers of the Greek Orthodox Church of Alexandria declined to approximately 90,000 by the beginning of the 13th century, and to only a few thousand by the onset of the Ottoman period. In the 1830s and 1840s, observers estimated the Eastern Orthodox community in Egypt at around 5,000 people. Most lived in Cairo, Alexandria, and Damietta, with smaller communities in Rosetta and Suez. In 1791, the Second plague pandemic severely affected this already small community.

Diaspora growth in the 19th century

In the 19th century Orthodoxy in Africa began to grow again. One thing that changed this in the 19th century was the Orthodox diaspora. People from Greece, Syria and Lebanon, in particular, went to different parts of Africa, and some established Orthodox churches. Many Greeks also settled in Alexandria from the 1840s and Orthodoxy began to flourish there again, and schools and printing presses were established.

For a while there was some confusion, especially outside Egypt. As happened in other places, Orthodox immigrants would establish an ethnic "community", which would try to provide a church, school, sporting and cultural associations. They would try to get a priest for the community in the place they had emigrated from, and there was some confusion about which bishops were responsible for these priests.
