Constantius II was Roman emperor from 337 to 361. His reign saw constant warfare on the borders against the Sasanian Empire and Germanic peoples, while internally the Roman Empire went through repeated civil wars, court intrigues, and usurpations. His religious policies inflamed domestic conflicts that would continue after his death.
Eusebius of Caesarea, also known as Eusebius Pamphilus, was a Greek Syro-Palestinian historian of Christianity, exegete, and Christian polemicist. In about AD 314 he became the bishop of Caesarea Maritima in the Roman province of Syria Palaestina.
Jerome, also known as Jerome of Stridon, was an early Christian priest, confessor, theologian, translator, and historian; he is commonly known as Saint Jerome.
Christian monasticism is a religious way of life of Christians who live ascetic and typically cloistered lives that are dedicated to Christian worship. It began to develop early in the history of the Christian Church, modeled upon scriptural examples and ideals, including those in the Old Testament. It has come to be regulated by religious rules and, in modern times, the Canon law of the respective Christian denominations that have forms of monastic living. Those living the monastic life are known by the generic terms monks (men) and nuns (women). The word monk originated from the Greek μοναχός, itself from μόνος meaning 'alone'.
Hilarion the Great (291–371) was an anchorite who spent most of his life in the desert according to the example of Anthony the Great (c. 251–356). While Anthony is considered to have established Christian monasticism in the Egyptian Desert, Hilarion is considered by some to be the founder of Palestinian monasticism and venerated as a saint by the Orthodox and the Roman Catholic Church.
Mar Awgin or Awgen, also known as Awgin of Clysma or Saint Eugenios, was an Egyptian monk who, according to traditional accounts, introduced Christian monasticism to Syriac Christianity. These accounts, however, are all of late origin and often contain anachronisms. The historicity of Awgin is not certain.
John Cassian, also known as John the Ascetic and John Cassian the Roman, was a Christian monk and theologian celebrated in both the Western and Eastern churches for his mystical writings. Cassian is noted for his role in bringing the ideas and practices of early Christian monasticism to the medieval West.
The Desert Fathers were early Christian hermits and ascetics, who lived primarily in the Scetes desert of the Roman province of Egypt, beginning around the third century AD. The Apophthegmata Patrum is a collection of the wisdom of some of the early desert monks and nuns, in print as Sayings of the Desert Fathers. The first Desert Father was Paul of Thebes, and the most well known was Anthony the Great, who moved to the desert in AD 270–271 and became known as both the father and founder of desert monasticism. By the time Anthony had died in AD 356, thousands of monks and nuns had been drawn to living in the desert following Anthony's example, leading his biographer, Athanasius of Alexandria, to write that "the desert had become a city." The Desert Fathers had a major influence on the development of Christianity.
Audianism, or Anthropomorphism, was a sect of Christians in the 4th century in Syria and the Pontic–Caspian steppe, named after its founder Audius or Audaeus, who interpreted the text of the First Epistle to Timothy 3:16 to mean that God created humanity in his image in a literal physical sense.
Evagrius Ponticus, also called Evagrius the Solitary, was a Christian monk and ascetic from Heraclea, a city on the coast of Bithynia in Asia Minor. One of the most influential theologians in the late fourth-century church, he was well known as a thinker, polished speaker, and gifted writer. He left a promising ecclesiastical career in Constantinople and traveled to Jerusalem, where in 383 AD he became a monk at the monastery of Rufinus and Melania the Elder. He then went to Egypt and spent the remaining years of his life in Nitria and Kellia, marked by years of asceticism and writing. He was a disciple of several influential contemporary church leaders, including Basil of Caesarea, Gregory of Nazianzus, and Macarius of Egypt. He was a teacher of others, including John Cassian and Palladius of Galatia.
Anthimus of Nicomedia, was the bishop of Nicomedia in Bithynia, where he was beheaded during a persecution of Christians, traditionally placed under Diocletian, in which "rivers of blood" flowed.
Saint Jerome in His Study is a painting by the Italian Renaissance master Antonello da Messina. The painting depicts human, natural, and divine knowledge, and is filled with architectural qualities. It was the property of Antonio Pasqualino and afterwards of Thomas Baring, 1st Earl of Northbrook; since 1894 it has been in the collection of the National Gallery, London.
Jovinianism refers to an anti-ascetic movement that has its origins in the 4th-century theologian Jovinian, who criticized the monastic movement and argued for the equality of marriage and celibacy. Jovinianism was criticized by Saint Augustine and Jerome.
Helvidius was the author of a work written prior to 383 against the belief in the perpetual virginity of Mary. Helvidius maintained that the biblical mention of "sisters" and "brothers" of the Lord constitutes solid evidence that Mary had normal marital relations with Joseph and additional children after the miraculous conception and birth of Jesus. He supported his opinion by the writings of Tertullian and Victorinus. Helvidius is sometimes seen as an early proto-protestant, along with Vigiliantius, Jovinian and Aerius of Sebaste.
Coptic monasticism was a movement in the Coptic Orthodox Church to create a holy, separate class of person from layman Christians.
In the 5th century in Christianity, there were many developments which led to further fracturing of the State church of the Roman Empire. Emperor Theodosius II called two synods in Ephesus, one in 431 and one in 449, that addressed the teachings of Patriarch of Constantinople Nestorius and similar teachings. Nestorius had taught that Christ's divine and human nature were distinct persons, and hence Mary was the mother of Christ but not the mother of God. The Council rejected Nestorius' view causing many churches, centered on the School of Edessa, to a Nestorian break with the imperial church. Persecuted within the Roman Empire, many Nestorians fled to Persia and joined the Sassanid Church thereby making it a center of Nestorianism. By the end of the 5th century, the global Christian population was estimated at 10-11 million. In 451 the Council of Chalcedon was held to clarify the issue further. The council ultimately stated that Christ's divine and human nature were separate but both part of a single entity, a viewpoint rejected by many churches who called themselves miaphysites. The resulting schism created a communion of churches, including the Armenian, Syrian, and Egyptian churches, that is today known as Oriental Orthodoxy. In spite of these schisms, however, the imperial church still came to represent the majority of Christians within the Roman Empire.
In 6th-century Christianity, Roman Emperor Justinian launched a military campaign in Constantinople to reclaim the western provinces from the Germans, starting with North Africa and proceeding to Italy. Though he was temporarily successful in recapturing much of the western Mediterranean he destroyed the urban centers and permanently ruined the economies in much of the West. Rome and other cities were abandoned. In the coming centuries the Western Church, as virtually the only surviving Roman institution in the West, became the only remaining link to Greek culture and civilization.
The concept of the Antichrist has been a vigorous one throughout Christian history, and there are many references to it and to associated concepts both in the Bible and in subsequent ecclesiastical writings.
Arabianus was an eminent Christian writer who lived around 196. He composed some books on Christian doctrine, which are lost. Nothing more is known of him, and the writers who mention him, like Eusebius, do not even tell us the title of the work Arabianus wrote. Jerome says that he wrote "certain small works relating to Christian doctrine."
Miltiades was a 2nd-century Christian, who wrote three treatises, "against the Greeks", "against the Jews" and an "Apology". He likely started writing before the death of Marcus Aurelius. Miltiades might have been associated with Montanism, however there is confusion as to if he was a Montanist, this is because In Eusebius' writings, there appears to be confusion over the name "Miltiades" and "Alcibiades", either due to an error from copyists or from Eusebius himself. It is even possible that he might have written against Montanism.
