Eastern Christianity comprises Christian traditions and church families that originally developed during classical and late antiquity in Eastern Europe, Southeastern Europe, Asia Minor, the Caucasus, Northeast Africa, the Fertile Crescent and the Malabar coast of South Asia, and ephimerally parts of Persia, Central Asia and the Far East. The term does not describe a single communion or religious denomination.
Yazdegerd I was the Sasanian King of Kings of Iran from 399 to 420. A son of Shapur III, he succeeded his brother Bahram IV after the latter's assassination.
Abdas, was bishop of Susa in Iran. Socrates of Constantinople calls him "bishop of Persia". He was executed under the orders of shah Yazdegerd I after to refusing to rebuild a Zoroastrian fire temple that he had destroyed.
Isaac or Sahak of Armenia (354–439) was Catholicos of the Armenian Apostolic Church. He is sometimes known as "Isaac the Great," and as "Sahak the Parthian" owing to his Parthian origin.
The Maphrian, originally known as the Grand Metropolitan of the East and also known as the Catholicos, was the second-highest rank in the ecclesiastical hierarchy of the Syriac Orthodox Church, right below that of patriarch. The office of a maphrian is an maphrianate. There have been three maphrianates in the history of the Syriac Orthodox Church and one, briefly, in the Syriac Catholic Church.
Aphrahat was a Syriac Christian author of the third century from the Persian / Sasanian Empire who composed a series of twenty-three expositions or homilies on points of Christian doctrine and practice. All his known works, the Demonstrations, come from later on in his life. He was an ascetic and celibate, and was almost definitely a son of the covenant. He may have been a bishop, and later Syriac tradition places him at the head of Mar Mattai Monastery near Mosul in what is now northern Iraq. He was a near contemporary to the slightly younger Ephrem the Syrian, but the latter lived within the sphere of the Roman Empire. Called the Persian Sage, Aphrahat witnessed to the concerns of the early church beyond the eastern boundaries of the Roman Empire.
Isaac of Seleucia was a Patriarch of the Persian Church, who is celebrated among the Catholicoi, the patriarchs of the Persian Church, for having reorganized the Church after the persecution that overwhelmed it under Shapûr II.
The Sasanian or Sassanid Empire, officially known as the Empire of Iranians and also referred to by historians as the Neo-Persian Empire, was the last Iranian empire before the early Muslim conquests of the 7th–8th centuries CE. Named after the House of Sasan, it endured for over four centuries, from 224 to 651 CE, making it the longest-lived Persian imperial dynasty. The Sasanian Empire succeeded the Parthian Empire, and re-established the Persians as a major power in late antiquity alongside its neighbouring arch-rival, the Roman Empire.
Mar Shimun Bar Sabbae was Bishop of Seleucia-Ctesiphon, from Persia, the de facto head of the Church of the East, until his death. He was bishop during the persecutions of King Shapur II of the Sasanian Empire of Iran, and was executed along with many of his followers. He is revered as a saint in various Christian communions.
The Council of Seleucia-Ctesiphon, also called the Council of Mar Isaac, met in AD 410 in Seleucia-Ctesiphon, the capital of the Persian Sassanid Empire. Convoked by King Yazdegerd I (399–421), it organized the Christians of his empire into a single structured Church, which became known as the Church of the East. It is often compared to Constantine's Edict of Milan, approximately a century earlier.
Christianity in the 4th century was dominated in its early stage by Constantine the Great and the First Council of Nicaea of 325, which was the beginning of the period of the First seven Ecumenical Councils (325–787), and in its late stage by the Edict of Thessalonica of 380, which made Nicene Christianity the state church of the Roman Empire.
Early Christianity spread from the Levant, across the Roman Empire, and beyond. Originally, this progression was closely connected to already established Jewish centers in the Holy Land and the Jewish diaspora. The first followers of Christianity were Jews or proselytes, commonly referred to as Jewish Christians and God-fearers.
Christianity in late antiquity traces Christianity during the Christian Roman Empire – the period from the rise of Christianity under Emperor Constantine, until the fall of the Western Roman Empire. The end-date of this period varies because the transition to the sub-Roman period occurred gradually and at different times in different areas. One may generally date late ancient Christianity as lasting to the late 6th century and the re-conquests under Justinian of the Byzantine Empire, though a more traditional end-date is 476, the year in which Odoacer deposed Romulus Augustus, traditionally considered the last western emperor.
The Church of the East or the East Syriac Church, also called the Church of Seleucia-Ctesiphon, the Persian Church or the Nestorian Church, was an Eastern Christian church of the East Syriac Rite, based in Mesopotamia. It was one of three major branches of Eastern Christianity that arose from the Christological controversies of the 5th and 6th centuries, alongside the Oriental Orthodox Churches and the Chalcedonian Church. During the early modern period, a series of schisms gave rise to rival patriarchates, sometimes two, sometimes three. Since the latter half of the 20th century, three churches in Iraq claim the heritage of the Church of the East. Meanwhile, the East Syriac churches in India claim the heritage of the Church of the East in India.
Isaac was bishop of Seleucia-Ctesiphon, grand metropolitan and primate of the Church of the East from 399 to 410. He is included in the traditional list of patriarchs of the Church of the East.
Marutha of Tikrit was the Grand Metropolitan of the East and head of the Syriac Orthodox Church of the East from 628 or 629 until his death in 649. He is commemorated as a saint by the Syriac Orthodox Church.
The Sassanid Empire or Sassanian Dynasty is the name used for the Persian dynasty which lasted from 224 to 651 AD.
Miles, sometimes Mar Miles, was the bishop of Susa in Sasanian Persia from before 315 until his martyrdom in 340 or 341. He engaged in efforts to evangelize Susa, traveled widely in the Eastern Roman Empire and led the opposition to Papa bar ʿAggai and the supremacy of the bishops of Seleucia-Ctesiphon in the Persian church. He was executed by the Sasanian authorities at the start of the Forty-Year Persecution.
