Christianity

Christianity[note 1][2] is an Abrahamic monotheistic[3] religious group[4] whose adherents believe that Jesus is the Son of God, the Logos, and the savior of humanity, whose coming as the Messiah (Christ) was prophesied in the Old Testament of the Bible, and chronicled in the New Testament.[5][need quotation to verify]

Christianity began as a Second Temple Judaic sect, in the 1st century, in the Roman province of Judea. Jesus' apostles and their successors, the Apostolic Fathers, spread it across large parts of the Middle East, Europe, Ethiopia, Transcaucasia and some other parts of Asia, despite initial persecution. Emperor Constantine the Great converted to Christianity and decriminalized it in the Edict of Milan (313), later convening the First Council of Nicaea (325) where Early Christianity was consolidated into what would become the state religion of the Roman Empire (380).[6][7][8] The council formulated the Nicene Creed (325), and the Church Fathers supervised the compilation of the Christian Bible (5th century).[9] Early statements of essential beliefs were the Apostles Creed and Nicene Creed. The period of the first seven ecumenical councils is sometimes referred to as the Great Church, the united communion of the Catholic Church, Eastern Orthodox Church, and Oriental Orthodoxy before their schisms. Oriental Orthodoxy split after the Council of Chalcedon (451) over differences in Christology, while the Eastern Orthodox Church and the Catholic Church separated in the East–West Schism (1054), especially over the authority of the Pope. Similarly, Protestantism split in numerous denominations from the Catholic Church in the Protestant Reformation (16th century) over theological and ecclesiological disputes.[10]

Christianity and Christian ethics have played a prominent role in the shaping of Western civilization.[11][12][13][14][15] Christianity was a leading influence on the development of Western civilization in Europe during Late Antiquity and the Middle Ages. Following the Age of Discovery (15th–17th century), Christianity was spread into the Americas, Oceania, Sub-Saharan Africa and the rest of the world via missionary work and colonization.[16][17][18]

It is the world's most populous religious group,[19][4] with over 2.4 billion followers,[20][21][22] or 33% of the global population, comprising a majority of the population in about two-thirds of the countries in the world.[22] Today, the four largest branches of Christianity are the Catholic Church (1.3 billion), Protestantism (920 million), the Eastern Orthodox Church (260 million)[23] and Oriental Orthodoxy (86 million).

Christianity grew out of Judaism[25][26][27] as a Second Temple Judaic sect in the 1st century[2][28] in the Roman province of Judea. Other religious influences of early Christianity are Zoroastrianism and Gnosticism.[28][29] John Bowker states that Christian ideas such as "angels, the end of the world, a final judgment, the resurrection and heaven and hell received form and substance from ... Zoroastrian beliefs".[30] Its earliest development took place under the leadership of the remaining Twelve Apostles, particularly Saint Peter, and Paul the Apostle, followed by the early bishops, whom Christians consider the successors of the Apostles.

According to the New Testament, Christians were from the beginning subject to persecution by some Jewish and Roman religious authorities. This involved punishments, including death, for Christians such as [Acts 7:59] and [Acts 12:2] Further widespread persecutions of the Church occurred under nine subsequent Roman emperors, most intensely under Decius and Diocletian.

From the year 150, Christian teachers began to produce theological and apologetic works aimed at defending the faith. These authors are known as the Church Fathers, and study of them is called patristics. Notable early Fathers include Ignatius of Antioch, Polycarp, Justin Martyr, Irenaeus, Tertullian, Clement of Alexandria and Origen.

King Trdat IV made Christianity the state religion in Armenia between 301 and 314.[31][32][33] It was not an entirely new religion in Armenia. It penetrated into the country from at least the third century but may have been present even earlier.[34]

End of Roman persecution under Emperor Constantine (AD 313)

State persecution ceased in the 4th century, when Constantine I and Licinius issued an edict of toleration in 313. At that point, Christianity was still a minority belief comprising perhaps only five percent of the Roman population.[35] Influenced by his adviser Mardonius, Constantine's nephew Julian unsuccessfully tried to suppress Christianity.[36] On 27 February 380, Theodosius I, Gratian, and Valentinian II established Nicene Christianity as the state church of the Roman Empire.[37] As soon as it became connected to the state, Christianity grew wealthy; the Church solicited donations from the rich and could now own land.[38] From at least the 4th century, Christianity has played a prominent role in the shaping of Western civilization.[39]

Constantine was also instrumental in the convocation of the First Council of Nicaea in 325, which sought to address Arianism and formulated the Nicene Creed, which is still used by the Catholic Church, Eastern Orthodoxy, Anglican Communion and many Protestant churches.[40] Nicaea was the first of a series of ecumenical councils which formally defined critical elements of the theology of the Church, notably concerning Christology.[41] The Assyrian Church of the East did not accept the third and following Ecumenical Councils, and are still separate today.

The presence of Christianity in Africa began in the middle of the 1st century in Egypt, and by the end of the 2nd century in the region around Carthage. Mark the Evangelist is claimed to have started the Church of Alexandria in about AD 43; various later churches and denominations claim this as their own legacy including the Coptic Orthodox Church of Alexandria.[42][43][44] Important Africans who influenced the early development of Christianity include Tertullian, Clement of Alexandria, Origen of Alexandria, Cyprian, Athanasius and Augustine of Hippo. The later rise of Islam in North Africa reduced the size and numbers of Christian congregations, leaving in large numbers only the Coptic Church in Egypt, the Ethiopian Orthodox Tewahedo Church in the Horn of Africa and the Nubian Church in the Sudan (Nobatia, Makuria and Alodia).

In terms of prosperity and cultural life, the Byzantine Empire was one of the peaks in Christian history and Christian civilization,[45] and Constantinople remained the leading city of the Christian world in size, wealth and culture.[46] There was a renewed interest in classical Greek philosophy, as well as an increase in literary output in vernacular Greek.[47] Byzantine art and literature held a pre-eminent place in Europe, and the cultural impact of Byzantine art on the west during this period was enormous and of long lasting significance.[48]

Early Middle Ages

With the decline and fall of the Roman Empire in the west, the papacy became a political player, first visible in Pope Leo's diplomatic dealings with Huns and Vandals.[49] The church also entered into a long period of missionary activity and expansion among the various tribes. While Arianists instituted the death penalty for practicing pagans (see Massacre of Verden as example), what would later become Catholicism also spread among the Hungarians, the Germanic,[49] the Celtic, the Baltic and some Slavic peoples. Christianity has been an important part of the shaping of Western civilization, at least since the 4th century.[12][13][39]

Around 500, St. Benedict set out his Monastic Rule, establishing a system of regulations for the foundation and running of monasteries.[49] Monasticism became a powerful force throughout Europe,[49] and gave rise to many early centers of learning, most famously in Ireland, Scotland and Gaul, contributing to the Carolingian Renaissance of the 9th century.

In the 7th century Muslims conquered Syria (including Jerusalem), North Africa and Spain, converting some of the Christian population to Islam, and placing the rest under a separate legal status. Part of the Muslims' success was due to the exhaustion of the Byzantine Empire in its decades long conflict with Persia.[50] Beginning in the 8th century, with the rise of Carolingian leaders, the papacy began to find greater political support in the Frankish Kingdom.[51]

The Middle Ages brought about major changes within the church. Pope Gregory the Great dramatically reformed ecclesiastical structure and administration.[52] In the early 8th century, iconoclasm became a divisive issue, when it was sponsored by the Byzantine emperors. The Second Ecumenical Council of Nicaea (787) finally pronounced in favor of icons.[53] In the early 10th century, Western Christian monasticism was further rejuvenated through the leadership of the great Benedictine monastery of Cluny.[54]

Hebraism, like Hellenism, has been an all-important factor in the development of Western Civilization; Judaism, as the precursor of Christianity, has indirectly had much to do with shaping the ideals and morality of western nations since the Christian era.[13]

High and Late Middle Ages

In the west, from the 11th century onward, older cathedral schools developed into universities (see University of Oxford, University of Paris and University of Bologna.) The traditional medieval universities—evolved from Catholic and Protestant church schools—then established specialized academic structures for properly educating greater numbers of students as professionals. Prof. Walter Rüegg, editor of A History of the University in Europe, reports that universities then only trained students to become clerics, lawyers, civil servants and physicians.[55]

Originally teaching only theology, universities steadily added subjects including medicine, philosophy and law, becoming the direct ancestors of modern institutions of learning.[56] The university is generally regarded as an institution that has its origin in the Medieval Christian setting.[57][58] Prior to the establishment of universities, European higher education took place for hundreds of years in Christian cathedral schools or monastic schools (Scholae monasticae), in which monks and nuns taught classes; evidence of these immediate forerunners of the later university at many places dates back to the 6th century AD.[59]

Accompanying the rise of the "new towns" throughout Europe, mendicant orders were founded, bringing the consecrated religious life out of the monastery and into the new urban setting. The two principal mendicant movements were the Franciscans[60] and the Dominicans[61] founded by St. Francis and St. Dominic respectively. Both orders made significant contributions to the development of the great universities of Europe. Another new order were the Cistercians, whose large isolated monasteries spearheaded the settlement of former wilderness areas. In this period church building and ecclesiastical architecture reached new heights, culminating in the orders of Romanesque and Gothic architecture and the building of the great European cathedrals.[62]

From 1095 under the pontificate of Urban II, the Crusades were launched.[63] These were a series of military campaigns in the Holy Land and elsewhere, initiated in response to pleas from the Byzantine Emperor Alexios I for aid against Turkish expansion. The Crusades ultimately failed to stifle Islamic aggression and even contributed to Christian enmity with the sacking of Constantinople during the Fourth Crusade.[64]

Over a period stretching from the 7th to the 13th century, the Christian Church underwent gradual alienation, resulting in a schism dividing it into a so-called Latin or Western Christian branch, the Catholic Church,[65] and an Eastern, largely Greek, branch, the Orthodox Church. These two churches disagree on a number of administrative, liturgical and doctrinal issues, most notably papal primacy of jurisdiction.[66][67] The Second Council of Lyon (1274) and the Council of Florence (1439) attempted to reunite the churches, but in both cases the Eastern Orthodox refused to implement the decisions and the two principal churches remain in schism to the present day. However, the Catholic Church has achieved union with various smaller eastern churches.

In the thirteenth century a new emphasis on Jesus' suffering, exemplified by the Franciscans' preaching, had the consequence of turning worshippers' attention towards Jews, on whom Christians had placed the blame for Jesus' death. Christianity's limited tolerance of Jews was not new—Augustine of Hippo had said that Jews should not be allowed to enjoy the citizenship that Christians took for granted—but the growing antipathy towards Jews was a factor that led to the expulsion of Jews from England in 1290, the first of many such expulsions in Europe.[68][69]

Beginning around 1184, following the crusade against the Cathar heresy,[70] various institutions, broadly referred to as the Inquisition, were established with the aim of suppressing heresy and securing religious and doctrinal unity within Christianity through conversion and prosecution.[71]

Protestant Reformation and Counter-Reformation

Martin Luther started the Protestant Reformation in 1517 with the Ninety-Five Theses, going against the Catholic interpretation of the Bible.

The 15th-century Renaissance brought about a renewed interest in ancient and classical learning. Another major schism, the Reformation, resulted in the splintering of the Western Christendom into several branches.[72] Martin Luther in 1517 protested against the sale of indulgences and soon moved on to deny several key points of Catholic doctrine.[73]

Other reformers like Zwingli, Oecolampadius, Calvin, Knox and Arminius further criticized Catholic teaching and worship. These challenges developed into the movement called Protestantism, which repudiated the primacy of the pope, the role of tradition, the seven sacraments and other doctrines and practices.[73] The Reformation in England began in 1534, when King Henry VIII had himself declared head of the Church of England. Beginning in 1536, the monasteries throughout England, Wales and Ireland were dissolved.[74]

Thomas Müntzer, Andreas Karlstadt and other theologians perceived both the Catholic Church and the confessions of the Magisterial Reformation as corrupted. Their activity brought about the Radical Reformation, which gave birth to various Anabaptist denominations.

Michelangelo's Pietà in St. Peter's Basilica, The Catholic Church was among the patronages of the Renaissance.[75][76][77]

Partly in response to the Protestant Reformation, the Catholic Church engaged in a substantial process of reform and renewal, known as the Counter-Reformation or Catholic Reform.[78] The Council of Trent clarified and reasserted Catholic doctrine. During the following centuries, competition between Catholicism and Protestantism became deeply entangled with political struggles among European states.[79]

Meanwhile, the discovery of America by Christopher Columbus in 1492 brought about a new wave of missionary activity. Partly from missionary zeal, but under the impetus of colonial expansion by the European powers, Christianity spread to the Americas, Oceania, East Asia and sub-Saharan Africa.

Throughout Europe, the divides caused by the Reformation led to outbreaks of religious violence and the establishment of separate state churches in Europe. Lutheranism spread into northern, central and eastern parts of present-day Germany, Livonia and Scandinavia. Anglicanism was established in England in 1534. Calvinism and its varieties (such as Presbyterianism) were introduced in Scotland, the Netherlands, Hungary, Switzerland and France. Arminianism gained followers in the Netherlands and Frisia. Ultimately, these differences led to the outbreak of conflicts in which religion played a key factor. The Thirty Years' War, the English Civil War and the French Wars of Religion are prominent examples. These events intensified the Christian debate on persecution and toleration.[80]

Post-Enlightenment

In the era known as the Great Divergence, when in the West the Age of Enlightenment and the scientific revolution brought about great societal changes, Christianity was confronted with various forms of skepticism and with certain modern political ideologies such as versions of socialism and liberalism.[81] Events ranged from mere anti-clericalism to violent outbursts against Christianity such as the dechristianisation of France during the French Revolution,[82] the Spanish Civil War and certain Marxist movements, especially the Russian Revolution and the persecution of Christians in the Soviet Union under state atheism.[83][84][85][86]

Especially pressing in Europe was the formation of nation states after the Napoleonic era. In all European countries, different Christian denominations found themselves in competition, to greater or lesser extents, with each other and with the state. Variables are the relative sizes of the denominations and the religious, political and ideological orientation of the state. Urs Altermatt of the University of Fribourg, looking specifically at Catholicisms in Europe, identifies four models for the European nations. In traditionally Catholic-majority countries such as Belgium, Spain and to some extent Austria, religious and national communities are more or less identical. Cultural symbiosis and separation are found in Poland, the Republic of Ireland and Switzerland, all countries with competing denominations. Competition is found in Germany, the Netherlands and again Switzerland, all countries with minority Catholic populations who to a greater or lesser extent did identify with the nation. Finally, separation between religion (again, specifically Catholicism) and the state is found to a great degree in France and Italy, countries where the state actively opposed itself to the authority of the Catholic Church.[87]

The combined factors of the formation of nation states and ultramontanism, especially in Germany and the Netherlands but also in England (to a much lesser extent[88]), often forced Catholic churches, organizations and believers to choose between the national demands of the state and the authority of the Church, specifically the papacy. This conflict came to a head in the First Vatican Council, and in Germany would lead directly to the Kulturkampf, where liberals and Protestants under the leadership of Bismarck managed to severely restrict Catholic expression and organization.

Christian commitment in Europe dropped as modernity and secularism came into their own in Europe,[89] particularly in the Czech Republic and Estonia,[90] while religious commitments in America have been generally high in comparison to Europe. The late 20th century has shown the shift of Christian adherence to the Third World and southern hemisphere in general, with the West no longer the chief standard bearer of Christianity. Approximately 7.1 to 10% of Arabs are Christians,[91] most prevalent in Egypt, Syria and Lebanon.
