When the Church of Alexandria was founded by Mark the Evangelist[1] during the reign of the Roman emperor Nero, a great multitude of native Egyptians (as opposed to Greeks or Jews) embraced the Christian faith.
All Christian monasticism stems, either directly or indirectly, from the Egyptian example: Basil the Great Archbishop of Caesaria of Cappadocia, founder and organiser of the monastic movement in Asia Minor, visited Egypt around 357 AD and his rule is followed by the Eastern Orthodox Churches; Jerome who translated the Bible into Latin, came to Egypt, while en route to Jerusalem, around 400 AD and left details of his experiences in his letters; Benedict founded the Benedictine Order in the 6th century on the model of Pachomius, but in a stricter form.
[4] In the 4th century, an Alexandrian presbyter named Arius began a theological dispute about the nature of Christ that spread throughout the Christian world and is now known as Arianism (not to be confused with the Nazi ideology Aryanism).
The Ecumenical Council of Nicea 325 AD was convened by the Roman Emperor Constantine I under the presidency of Hosius of Cordova and Pope Alexander I of Alexandria to resolve the dispute and eventually led to the formulation of the Symbol of Faith, also known as the Nicene Creed.
[This quote needs a citation] Another theological dispute in the 5th century occurred over the teachings of Nestorius, the Patriarch of Constantinople who taught that God the Logos was not hypostatically joined with human nature, but rather dwelt in the man Jesus.
When reports of this reached the Apostolic Throne of Saint Mark, Pope Cyril I of Alexandria acted quickly to correct this breach with orthodoxy, requesting that Nestorius repent.
This epistle drew heavily on the established Patristic Constitutions and contained the most famous article of Alexandrian Orthodoxy: "The Twelve Anathemas of Saint Cyril."
It also clearly stated that anyone who separated Christ into two hypostases was anathema, as Cyril had said that there is "One Nature [and One Hypostasis] for God the Word Incarnate" (Mia Physis tou Theou Logou Sesarkōmenē).
Glory to you O our Master and King: Christ, the pride of the Apostles, the crown of the martyrs, the rejoicing of the righteous, firmness of the churches and the forgiveness of sins.
The Council of Chalcedon, from the perspective of the Alexandrine Christology, has deviated from the approved Cyrillian terminology and declared that Christ was one hypostasis in two natures.
However, in the Nicene-Constantinopolitan Creed, "Christ was conceived of the Holy Spirit and of the Virgin Mary," thus the foundation of the definition according to the non-Chalcedonian adherents, according to the Christology of Cyril of Alexandria is valid.
To make thing even worse, the Tome of Pope Leo of Rome was, according to the Alexandria school of theology, particularly in regards to the definition of Christology, considered influenced by Nestorian heretical teachings.
By anathemizing Pope Leo, because of the tone and content of his Tome, as per Alexandrine theology perception, Pope Discoros was found guilty of doing so, without due process, in other words, the Tome of Leo was not a subject of heresy in the first place, but it was a question of questioning the reasons behind not having it either acknowledged or read at the Second Council of Ephesus in 449 AD.
Copts also believe that the Pope of Alexandria was forcibly prevented from attending the third congregation of the council from which he was ousted, apparently the result of a conspiracy tailored by the Roman delegates.
A term that comes closer to Coptic Orthodoxy is miaphysite, which refers to a conjoined nature for Christ, both human and divine, united indivisibly in the Incarnate Logos.
The Melkite Patriarchs, appointed by the emperors as both spiritual leaders and civil governors, massacred the Egyptian population whom they considered heretics.
[10] During Islamic rule, the Copts were required to pay a special tax, called the jizya, in return for defense from the Caliphate as non-Muslims were not allowed to serve in the army.
