 permitting the practice of the Christian religion under his rule. During the years 313 to the year 380, Christianity enjoyed the status of being a 'legal religion' within the Roman Empire. During these years, it had not yet become the sole authorized state religion, however during this period it gradually but continually gained in prominence and stature within Roman society. After halting the persecutions of the Christians, Galerius reigned for another 2 years. He was then succeeded by an emperor with distinctively pro Christian leanings, Constantine the Great.

Christianity legalized by Constantine I

Christian sources record that Constantine experienced a dramatic event in 312 at the Battle of Milvian Bridge
Battle of Milvian Bridge
The Battle of the Milvian Bridge took place between the Roman Emperors Constantine I and Maxentius on 28 October 312. It takes its name from the Milvian Bridge, an important route over the Tiber. Constantine won the battle and started on the path that led him to end the Tetrarchy and become the...

), and thereafter they were victorious. How much Christianity Constantine adopted at this point is difficult to discern; most influential people in the empire, especially high military officials, were still pagan, and Constantine's rule exhibited at least a willingness to appease these factions. The Roman coins minted up to eight years subsequent to the battle still bore the images of Roman gods. Nonetheless, the accession of Constantine was a turning point for the Christian Church. After his victory, Constantine supported the Church financially, built various basilicas, granted privileges (e.g., exemption from certain taxes) to clergy, promoted Christians to high ranking offices, and returned property confiscated during the Great Persecution of Diocletian. Between 324 and 330, Constantine built, virtually from scratch, a new imperial capital at Byzantium on the Bosphorus (it came to be named for him: Constantinople

)–the city employed overtly Christian architecture, contained churches within the city walls (unlike "old" Rome), and had no pagan temples.

Constantine I's formative influence in the 'Romanization' of Christianity

Under the influence of Constantine I, the Christian movement gradually underwent its major transformation from a previously underground and even criminal movement into an officially sanctioned religion of 'first rank' within the Roman Empire. Constantine I chose to take a lead role in much of this transformation. In 316 he acted as a judge in a North African dispute concerning the Donatist controversy. More significantly, in 325 he summoned the Council of Nicaea

The reign of Constantine established a precedent for the position of the Christian Emperor in the Church. Emperors considered themselves responsible to God

 for the spiritual health of their subjects, and thus they had a duty of maintain orthodoxy. The emperor did not decide doctrine – that was the responsibility of the bishops – rather his role was to enforce doctrine, root out heresy, and uphold ecclesiastical unity. The emperor ensured that God was properly worshiped in his empire; what proper worship consisted of was the responsibility of the church. This precedent would continue until certain emperors of the 5th and 6th centuries sought to alter doctrine by imperial edict without recourse to councils, though even after this Constantine's precedent generally remained the norm.

Ecumenical Councils of the 4th century



Beginning with those called by Constantine, the most significant role of the councils of the 4th and 5th centuries was to define orthodoxy within the Empire. These were mostly concerned with Christological disputes. The two Councils of Nicaea (325, 382) condemned Arian teachings as heresy and produced a creed (see Nicene Creed

This method of monastic organization is called cenobitic or "community-based." All the principal monastic orders are cenobitic in nature. In Catholic theology, this community-based living is considered superior because of the obedience practiced and the accountability offered. The head of a monastery came to be known by the word for "Father;" – in Syriac, Abba; in English, "Abbot

Eastern monasticism


Orthodox monasticism does not have religious orders as in the West, so there are no formal Monastic Rules (Regulae); rather, each monk and nun is encouraged to read all of the Holy Fathers and emulate their virtues. There is also no division between the "active" and "contemplative" life. Orthodox monastic life embraces both active and contemplative aspects.

Historical development

Among the first to set forth precepts for the monastic life was Saint Basil the Great

. Saint Basil visited colonies of hermits in Palestine and Egypt but was most strongly impressed by the organized communities developed under the guidance of Saint Pachomius. Saint Basil's ascetical writings set forth standards for well-disciplined community life and offered lessons in what became the ideal monastic virtue: humility.

Saint Basil wrote a series of guides for monastic life (the Lesser Asketikon the Greater Asketikon the Morals, etc.) which, while not "Rules" in the legalistic sense of later Western rules, provided firm indications of the importance of a single community of monks, living under the same roof, and under the guidance—and even discipline—of a strong abbot. His teachings set the model for Greek and Russian monasticism but had less influence in the Latin West.

The Eastern Monastic or Ascetic tradition

With the elevation of Christianity to the status of a legal religion within the Roman Empire by Constantine the Great, with the edict of Milan (313), many Orthodox felt a new decline in the ethical life of Christians. In reaction to this decline, many refused to accept any compromises and fled the world

 where he gathered a community around his hermitage. He was called to become Bishop of Tours in 372, where he established a monastery at Marmoutiers on the opposite bank of the Loire River, a few miles upstream from the city. His monastery was laid out as a colony of hermits rather than as a single integrated community.

John Cassian began his monastic career at a monastery in Palestine and Egypt around 385 to study monastic practice there. In Egypt he had been attracted to the isolated life of hermits, which he considered the highest form of monasticism, yet the monasteries he founded were all organized monastic communities. About 410 he established two monasteries near Marseilles, one for men, one for women. In time these attracted a total of 5,000 monks and nuns. Most significant for the future development of monasticism were Cassian's Institutes, which provided a guide for monastic life and his Conferences, a collection of spiritual reflections.

Honoratus of Marseilles was a wealthy Gallo-Roman aristocrat, who after a pilgrimage to Egypt, founded the Monastery of Lérins

. The monastery combined a community with isolated hermitages where older, spiritually-proven monks could live in isolation.

One Roman reaction to monasticism was expressed in the description of Lérins by Rutilius Namatianus, who served as prefect of Rome in 414:
A filthy island filled by men who flee the light.
Monks they call themselves, using a Greek name.
Because they will to live alone, unseen by man.
Fortune's gifts they fear, dreading their harm:
Mad folly of a demented brain,
That cannot suffer good, for fear of ill.


Lérins became, in time, a center of monastic culture and learning, and many later monks and bishops would pass through Lérins in the early stages of their career. Honoratus was called to be Bishop of Arles and was succeeded in that post by another monk from Lérins. Lérins was aristocratic in character, as was its founder, and was closely tied to urban bishoprics.

The events leading to schism were not exclusively theological in nature. Cultural, political, and linguistic differences were often mixed with the theological. Any narrative of the schism which emphasizes one at the expense of the other will be fragmentary.
Unlike the Coptics or Armenians who broke from the Church in the 5th century and established ethnic churches at the cost of their universality and catholicity, the eastern and western parts of the Church remained loyal to the faith and authority of the seven ecumenical councils. They were united, by virtue of their common faith and tradition, in one Church.

New Rome

When the Roman Emperor Constantine the Great embraced Christianity, he summoned the First Ecumenical Council at Nicaea in 325 to resolve a number of issues which troubled the Church. The bishops at the council confirmed the position of the metropolitan sees of Rome and Alexandria as having authority outside their own province, and also the existing privileges of the churches in Antioch and the other provinces. These sees were later called Patriarchate

) continued to thrive. Thus, the political unity of the Roman Empire was the first to fall.

In the West, the collapse of civil government left the Church practically in charge in many areas, and bishops took to administering secular cities and domains. When royal and imperial rule reestablished itself, it had to contend with power wielded independently by the Church. In the East, however, imperial and, later, Islamic rule dominated the Eastern bishops of Byzantium. Where as the Orthodox regions that were predominately Slavic experienced period foreign dominance as well as period without infrastructure (see the Tatars and Russia).

It was first among the communities that recognized each other as catholic churches holding the orthodox faith concerning God's Gospel in Jesus.

, bearer of the Father's name.' The Roman church held this place of honor and exercised a 'presidency in love' among the first Christian churches for two reasons. It was founded on the teaching and blood of the foremost Christian apostles Peter and Paul. And it was the church of the capital city of the Roman empire that then constituted the 'civilized world (oikoumene)'."

In the 4th century when the Roman emperors were trying to control the Church, theological questions were running rampant throughout the Roman Empire. The influence of Greek speculative thought on Christian thinking led to all sorts of divergent and conflicting opinions. Christ's commandment to love others as He loved

, seemed to have been lost in the intellectual abstractions of the time. Theology was also used as a weapon against opponent bishops, since being branded a heretic was the only sure way for a bishop to be removed by other bishops. Incompetence was not sufficient grounds for removal.

In the early church up until the ecumenical councils, Rome was regarded as an important centre of Christianity, especially since it was the capital of the Roman Empire. The eastern and southern Mediterranean bishops generally recognized a persuasive leadership and authority of the Bishop of Rome, because the teaching of the bishop of Rome was almost invariably correct. But the Mediterranean Church did not regard the Bishop of Rome as any sort of infallible source, nor did they acknowledge any juridical authority of Rome.

, whose actual teaching is now recognised to be not overtly heretical, although it is clearly deficient, (Saint Cyril called it 'slippery'), other patriarchs were able to make the charge of heresy stick and successfully had him deposed. This was probably more because his Christology was delivered with a heavy sarcastic arrogance which matched his high-handed personality.

The opinion of the Bishop of Rome was often sought, especially when the patriarchs of the Eastern Mediterranean were locked in fractious dispute. The bishops of Rome never obviously belonged to either the Antiochian

The opinion of the bishop of Rome was always canvassed, and was often longed for. However the Bishop of Rome's opinion was by no means automatically right.

But it was not universally accepted and was even called "impious" and "blasphemous" by some. The next ecumenical council corrected a possible imbalance in Pope Leo's presentation.

Neither do other Apostles proceed individually on their own; and anyone who would set up another chair in opposition to that single chair would, by that very fact, be a schismatic and a sinner".

Later conversions happened among the Grecian-Roman-Celtic populations over centuries, again mostly among its urban population and only spread to rural populations in much later centuries.

Consequently, while the initial converts were found among the Jewish

Year 340 was a leap year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Acindynus and Valerius...

. Though the religious motives were never unrelated, the primary cause of the persecution was political. When Rome became Christian, its old enemy turned anti-Christian.

Up to then the situation had been reversed. For the first 300 hundreds after Christ it was in the West that Christians were persecuted. For two hundred and fifty years Persia had been a refuge from Roman persecution. The Parthians were too religiously tolerant to persecute, and their less tolerant Sassanian successors on the throne were too busy fighting Rome, Persian emperors were inclined to regard them as friends of Persia.

It was about 315 that an ill-advised letter from the Christian emperor Constantine to his Persian counterpart Shapur II

 probably triggered the beginnings of an ominous change in the Persian attitude toward Christians. Constantine believed he was writing to help his fellow believers in Persia but succeeded only in exposing them. He wrote to the young shah:
"I rejoice to hear that the fairest provinces of Persia are adorned with...Christians...Since you are so powerful and pious, I commend them to your care, and leave them in your protection".

It was enough to make any Persian ruler conditioned by 300 years of war with Rome suspicious of the emergence of a fifth column. Any lingering doubts must have been dispelled when about twenty years later when Constantine began to gather his forces for war in the East. Eusebius records that Roman bishops were prepared to accompany their emperor to "battle with him and for him by prayers to God whom all victory proceeds". And across the border in Persian territory the forthright Persian preacher Aphrahat recklessly predicted on the basis of his reading of Old testament prophecy that Rome would defeat Persia.

It is little wonder then, that when the persecutions began shortly thereafter, the first accusation brought against the Christians was that they were aiding the Roman enemy. The shah Shapur II's response was to order a double taxation on Christians and to hold the bishop responsible for collecting it. He knew they were poor and that the bishop would be hard-pressed to find the money. Bishop Simon refused to be intimidated. He branded the tax as unjust and declared, "I am no tax collector but a shepherd of the Lord's flock." Then the killings began.

A second decree ordered the destruction of churches and the execution of clergy who refused to participate in the national worship of the sun. Bishop simon was seized and brought before the shah and was offered gifts to make a token obeisance to the sun, and when he refused, they cunningly tempted him with the promise that if he alone would apostatize his people would not be harmed, but that if he refused he would be condemning not just the church leaders but all Christians to destruction. At that, the Christians themselves rose up and refused to accept such a deliverance as shameful. So according to the tradition in the year 344

, he was led outside the city of Susa along with a large number of Christian clergy. Five bishops and one hundred priests were beheaded before his eyes, and last of all he himself was put to death.

For the next two decades and more, Christians were tracked down and hunted from one end of the empire to the other. At times the pattern was general massacre. More often, as Shapur decreed, it was intensive organized elimination of the leadership of the church, the clergy. A third category of suppression was the search for that part of the Christian community that was most vulnerable to persecution, Persians who had been converted from the national religion, Zoroastrianism. As we have already seen, the faith had spread first among non-Persian elements in the population, Jews and Syrians. But by the beginning of the 4th century, Iranians in increasing numbers were attracted to the Christian faith. For such converts, church membership could mean the loss of everything – family, property rights, and life itself. Converts from the "national faith" had no rights and, in the darker years of the persecution, were often put to death. The major agents in the slaughter were Zoroastrian clergy, but sometimes Christians suspected the Jews and accused them of acting as informers.

The martyrdom of Simon and the years of persecution that followed wiped out the beginnings of the central national organization the Persian church had only so recently achieved. As fast as the Christians of the capital elected a new bishop after Simon, the man was seized and killed. Inflaming the anti-Roman political motivation of the government's role in the persecutions was a deep undercurrent of Zoroastrian fanaticism and hatred of other religions.

Conditioning factors of missionary expansion

Several important factors help to explain the extensive growth in the Church of the East

 during the first twelve hundred years of the Christian era. Geographically, and possibly even numerically, the expansion of this church outstripped that of the church in the West in the early centuries. The outstanding key to understanding this expansion is the active participation of the laymen – the involvement of a large percentage of the church's believers in missionary evangelism. The following significant factors inducing that church growth are all based largely on the fact that it was a lay as well as a clerical movement.

3) Persecution strengthened and spread the Christian movement in the East. A great influx of Christian refugees from the Roman persecutions of the first two centuries gave vigour to the Mesopotamian church And persecution within the Persian empire saw thousands slain for the faith (at least 16,000 under the reign of Sapor II, AD 307

 (420–38), more terrible persecution broke out, culminating in the massacre of ten bishops and 153,000 Christians within a few days.

During the early centuries Christianity also penetrated Arabia from numerous points on its periphery. The kingdom of Hira in northeastern Arabia and near the border of Mesopotamia flourished from the end of the 3rd to the end of the 6th and was apparently evangelized by Christians from the Tigris-Euphrates Valley in the 4th century.

 and in Oman, with all connected with the Church of the East in the Persian Empire. Arabian bishops were found among those in attendance at important church councils in Mesopotamia. in the 7th century, however, with the rise of Islam seriously inhibited the growth of the church in Arabia. The regulations imposed throughout Persian and Arab territories upon non-Muslims however, progressively reduced both the numbers and public roles of Christians. Yet it was only in the wake of the Crusades that the antagonism between Christian and Muslim become sharp enough to bring comprehensive discrimination and the consequent dismantling of Christian influence. Existing churches were gradually eliminated by Muslim oppression. Many of the remaining Christians fled the country and found refuge in Mesopotamia.

Persecution often thrust them forth into new and unevangelized lands to find refuge. The dissemination of the gospel by largely Syriac-using people had its advantages, but it was also a hindrance to indigenizing the church in the new areas. Because Syriac never became dominant, competition from ethnic religions was always a serious problem. For these reasons of political vicissitude, in later centuries Christianity suffered an almost total eclipse in Asia until the modern period. The golden age of early missions in central Asia extended from the end of the fourth to the latter part of the 9th century, although in the Far East
