Template:Christianity sidebar Template:History of religion The history of Christianity began with the life of Jesus, an itinerant Jewish preacher and teacher, who was crucified in Jerusalem Template:Circa. His followers proclaimed that he was the incarnation of God and had risen from the dead. In the two millennia since, Christianity has spread across the world, becoming the world's largest religion with over two billion adherents worldwide.

Christianity was initially a grassroots movement spread within cities by apostles, reaching critical mass by the third century when it grew to over a million adherents. The support of the Roman emperor Constantine in the early fourth century was important in transforming it into an organized religion with a formalized religious text, allowing Christian art, architecture, and literature to blossom. Competing theological doctrines led to divisions, which were addressed by the Nicene Creed of 325. The subsequent 5th-century Nestorian schism produced the Church of the East and Oriental Orthodoxy. While the Western Roman Empire ended in 476, its successor states and its eastern compatriot—which became the Byzantine Empire—remained Christian.

In the Middle Ages, western monks preserved culture and provided social services. Early Muslim conquests devastated many Christian communities in the Middle East and North Africa, but Christianization continued in Europe and Asia and helped form the states of Eastern Europe. The 1054 East–West Schism saw the Byzantine Empire's Eastern Orthodoxy and Western Europe's Catholic Church separate. In spite of differences, the East requested western military aid against the Turks, resulting in the Crusades. Faced with internal and external challenges, the church fought heresy and established courts of inquisition. Gregorian reform led to a more centralized and bureaucratic Catholicism. Artistic and intellectual advances among western monks laid the foundations for the Renaissance and the scientific revolution.

In the 14th century, the Western Schism and several European crises led to the 16th-century Reformation when Protestantism split-off from the Catholic church. Quarrelling royal houses precipitated the European wars of religion. Christianity spread with the colonization of the Americas, Australia, and New Zealand. Different parts of Christianity variously influenced the Age of Enlightenment, American and French Revolutions, the Industrial Revolution, and the Atlantic slave trade. Some Protestants created biblical criticism while others responded to rationalism with Pietism and religious revivals that created new denominations. Protestants advocated for religious tolerance, separation of church and state, and moral reform, while nineteenth century missionaries laid the linguistic and cultural foundation for many nations. In the 20th century, Christianity declined in most of the West but grew in the East and Global South.

Christianity began with Jesus of Nazareth, a Jewish man and itinerant preacher in Galilee and the Roman province of Judea during the first century.Template:Sfn Template:Sfn Much about Jesus is uncertain, but his crucifixion Template:Circa is well attested.Template:Sfn Template:Sfn Template:Sfn The religious, social, and political climate in both regions was extremely diverse and characterized by turmoil with numerous religious and political movements.Template:Sfn Template:Sfn Template:Sfn One such movement, Jewish messianism, promised a messianic redeemer descended from Israel's ancient king, David, who would save Israel. Those who followed Jesus, called disciples, saw him as that Messiah.Template:Sfn Template:Sfn Template:Sfn

Jesus was a prophetic figure who proclaimed an "end-of-the-world" eschatological message of the coming kingdom of God.Template:Sfn Incarnation, the belief that God (or the Word of God) was embodied in Jesus,Template:Sfn Template:Sfn and resurrection, the belief that after his crucifixion, he rose from the dead,Template:Sfn Template:Sfn were Christianity's earliest beliefs.Template:Sfn Template:Sfn Its earliest rituals were baptism, a rite of initiation, and the communal Eucharist, a celebration in memory of Jesus' last meal before death.Template:Sfn Template:Sfn

The first Christian communities were predominantly Jewish.Template:Sfn Template:Sfn They gathered in small groups inside private homes where the typical setting for worship was the communal meal.Template:Sfn Template:Sfn Elders (called presbyters or bishops) oversaw the small groups, providing for the economic requirements of the meal and charitable distributions.Template:Sfn Template:Sfn Template:Sfn Template:Sfn Women comprised significant numbers of Christianity's earliest members.Template:Sfn Religion had appeal because women could attain greater freedom through religious activities than Roman customs otherwise permitted.Template:Sfn Template:Sfn Template:Sfn Template:Sfn The Pauline epistles recognize their presence in early Christian congregations.Template:Sfn Template:Sfn Christianity likely began with fewer than 1000 believers, which grew to approximately one hundred small household churches, each with an average of seventy members, by the year 100.Template:Sfn

Of the original believers, Jesus kept twelve disciples close to him who became known as the Apostles.Template:Sfn Saul of Tarsus, who became Paul the Apostle, was a Jewish Pharisee who had not known Jesus and persecuted early Christians. According to his own account, his life turned in the opposite direction after experiencing a vision of Christ on the road to Damascus.Template:Sfn Paul, Peter, and James, Jesus' brother, were probably the three most influential Christians in the first century, but all twelve Apostles crossed the ancient world to share their message, founding churches, and creating converts who then also established churches.Template:Sfn Template:Sfn Template:Sfn

Christianity was largely an urban religionTemplate:Sfn that spread through the Jewish diaspora Template:Sfn Template:Sfn along the trade and travel routes.Template:Sfn Template:Sfn Template:Sfn Despite the martyrdoms of Stephen and James the brother of John the Apostle, and the imprisonment of Peter, the movement grew, reaching Antioch, where converts were first called Christian by non-Christians.Template:Sfn Template:Sfn From Antioch, Barnabas and Paul went out as missionaries to Cyprus, then Asia Minor, where the gospel was received by both Jewish and non-Jewish people.Template:Sfn The largest cities in the Roman Empire, such as Rome, Alexandria, Antioch, Ephesus, and Carthage, all had Christian congregations by the end of the first century.Template:Sfn

The conversion of Gentiles led to disputes with a group who desired observance of Mosaic law including circumcision.Template:Sfn Template:Sfn James, Jesus' brother, called the Council of Jerusalem (Template:Circa) which determined that converts should avoid "pollution of idols, fornication, things strangled, and blood" but should not be required to follow other aspects of Jewish Law (KJV, Acts 15:20–21).Template:Sfn As Christianity grew in the Gentile world, it underwent a gradual separation from Judaism.Template:Sfn Template:Sfn Disagreements over Jewish law, progenitors of Rabbinic Judaism, and insurrections against Rome, contributed to this separation.Template:Sfn Template:Sfn Nevertheless, Jewish Christianity remained influential in Palestine, Syria, and Asia Minor into the second and third centuries.Template:Sfn Template:Sfn

In the early centuries, the languages most used to spread Christianity were Greek, Syriac (a form of Aramaic), and Latin.Template:Sfn Christian writings in Koine Greek, including the four gospels (the accounts of Jesus' ministry), letters of Paul, and letters attributed to other early Christian leaders, were written in the first century and had considerable authority, even in the formative period.Template:Sfn Template:Sfn Letters sent by Paul the Apostle to Christian communities were circulating in collected form by the end of the first century.Template:Sfn

Ante-Nicene period (100–312)

Template:Main Template:Further The Christian faith spread east into Syria and Mesopotamia where the population spoke Aramaic, not Greek. Aramaic Christians were in Adiabene (northern Iraq) by the second century.Template:Sfn It had spread into North Africa in the first century, and by the third century, it had spread across the Mediterranean region, from Greece and Anatolia into the Balkans in the East, and as far as Roman Britain in the northwest.Template:Sfn Template:Sfn

Christianity's different ideas, combined with the social impact of the church, were pivotal to this growth.Template:Sfn Template:Sfn Christianity offered people new ways of thinking.Template:Sfn Template:Sfn Template:Sfn Template:Sfn For example, the idea that the power of God was manifested through Jesus in a reversal of power challenged Roman concepts of hierarchy.Template:Sfn Template:Sfn Template:Sfn

The Ante-Nicene period included sporadic but increasing persecution from Roman authorities, as well as the rise of Christian sects, cults, and movements.Template:Sfn Christians were persecuted because they did not uphold fundamental beliefs of Roman society and their withdrawal from public religion made them targets of suspicion and rumor.Template:Sfn Template:Sfn Template:Sfn Template:Sfn For most of its early centuries, Christianity was tolerated, and episodes of persecution were local.Template:Sfn Emperor Nero's persecution of Christians during the mid-1st century was confined to Rome. There were no empire-wide persecutions until the 250s.Template:Sfn Official persecution reached its height under Diocletian in 303–311.Template:Sfn Template:Sfn Template:Sfn

In sociologist Rodney Stark's view, Christianity constituted an "intense community" which provided a unique "sense of belonging".Template:Sfn Template:Sfn Early Christianity demonstrates both inclusion and exclusion.Template:Sfn Baptism was free and there were no fees, which made Christianity more affordable than traditional Roman religions.Template:Sfn Template:Sfn Belief in the resurrection of Jesus was the crucial and defining characteristic for becoming a Christian, and early Christianity was highly inclusive of any who expressed such belief.Template:Sfn Template:Sfn Ancient philosophy Professor Danny Praet writes that believers were also separated from unbelievers by a strong social boundary in a unique type of exclusivity based on belief rather than traditional Roman ritual.Template:Sfn Template:Sfn Template:Sfn Template:Multiple image Women are prominent in the Pauline epistlesTemplate:Sfn Template:Sfn and early Christian art,Template:Sfn while much early anti-Christian criticism was linked to "female initiative" indicating their role in the movement.Template:Sfn Template:Sfn Template:Sfn Template:Refn The church rolls from the second century list groups of women "exercising the office of widow".Template:Sfn Template:Sfn There are few records of early Christian art, but the oldest emerged in the catacombs of Rome between 200 and 400.Template:Sfn Template:Sfn Template:Sfn It typically fused Graeco-Roman style and Christian symbolism: the most common image was Jesus as the good shepherd.Template:Sfn Template:Sfn

By 200, Christian numbers had grown to over 200,000 people, and communities with an average size of 500–1000 people existed in approximately 200–400 towns. By 250, Christianity had grown to over a million.Template:Sfn Template:Sfn House churches were then succeeded by buildings designed to be churches, complete with assembly rooms, classrooms, and dining rooms.Template:Sfn Template:Sfn A more formal church government developed at different times in different locations. Bishops were essential to this development, and they rose in power and influence as they began to preside over larger areas with multiple churches.Template:Sfn Template:Sfn Template:Sfn Template:Sfn

The four gospels and the letters of Paul were generally regarded as authoritative, but other writings, such as the Book of Revelation and the epistles to the Hebrews, James, and 1 John, were assigned different degrees of authority.Template:Sfn Template:Sfn Template:Sfn Gnostic texts challenged the physical nature of Jesus, Montanism suggested that the apostles could be superseded, and Monarchianism emphasized the unity of God over the Trinity.Template:Sfn In the face of such diversity, unity was provided by the shared scriptures and bishops.Template:Sfn Template:Sfn

The fluidity of the New Testament in the first century does not seem to have affected belief in the Trinity as it connected to Christology and salvation. Christianity's central mystery, the Trinity, defines the Holy Spirit, Father, and Son as one God in three persons.Template:Sfn However, there is an evolution of thought in the Patristic writings, then the development of the canon, and later in the theological controversies of the fourth century, that shaped the concept's development and gradually created a more technical Trinitarian vocabulary.Template:Sfn Template:Sfn

Late antiquity (313 – c. 600)

Template:Main Template:See also Late Antiquity was an age of change in which Christianity became a permitted religion, then a favored one that transformed in every capacity.Template:Sfn In 313, the emperor Constantine, a self-declared Christian, issued the Edict of Milan expressing tolerance for all religions.Template:Sfn Thereafter, he supported Christianity by giving bishops judicial power and establishing them as legally equal to polytheistic priests.Template:Sfn He devoted personal and public funds to building churches and endowed them with funds to support their clergy.Template:Sfn There were churches in the majority of Roman cities by the end of the fourth century.Template:Sfn

Christian art, architecture, and literature blossomed under Constantine.Template:Sfn Template:Sfn The basilica, a type of Roman municipal court hall, became the model for Christian architecture.Template:Sfn Frescoes, mosaics, statues, and paintings blended classical and Christian styles.Template:Sfn Similarly, a hybrid form of poetry written in classical styles with Christian concepts emerged.Template:Sfn Template:Sfn Template:Sfn In the late fourth century, Jerome was commissioned to translate the Greek biblical texts into the Latin language; this translation was called the Vulgate.Template:Sfn Church fathers of this period, such as Augustine of Hippo, John Chrysostom, Gregory of Nyssa, Athanasius of Alexandria, Basil of Caesarea, Gregory of Nazianzus, Cyril of Alexandria, and Ambrose of Milan, wrote vast numbers of works.Template:Sfn

The ascetic ideal of these early church fathers was also embraced by monasticism, which had begun earlier in Syria, and was key to the development of Christianity.Template:Sfn Template:Sfn Template:Sfn In Late Antiquity, these communities became associated with the urban holy places in Palestine, Cappadocia, Italy, Gaul, and Roman North Africa.Template:Sfn In the 370s, Basil the Great founded the Basileias, a monastic community in Caesarea (Mazaca) which developed the first health care system for the poor, a forerunner of modern public hospitals.Template:Sfn

Christianity's social impact, especially its charitable practices,Template:Sfn contributed to its spread, despite competition from traditional polytheism and alternative cults and creeds.Template:Sfn Template:Sfn Template:Refn There was no legislation forcing the conversion of pagans before the Byzantine Emperor Justinian I (Template:Reign), and polytheism remained in some places into the ninth century.Template:Sfn Template:Sfn Template:Sfn Template:Sfn Even so, blood sacrifice, which had been a central rite of virtually all religious groups in the pre-Christian Mediterranean, disappeared by the end of the fourth century due to hostile imperial laws.Template:Sfn Template:Sfn

While there was legal hostility, actual religious violence between pagans and Christians was not a general phenomenon.Template:Sfn Scholars "concur that the once-dominant notion of overt pagan–Christian religious conflict cannot fully explain the ... realities of late antique Rome."Template:Sfn Constantine institutionalized the Church, forcing Christians to adapt as much as pagans, as each group strove to negotiate their new identities. Tensions emerged after 312, and a number of violent riots were fueled by crowd hatred that included religious difference as one of several factors.Template:Sfn Still, coexistence in a competitive spirit, with only occasional conflict, formed the central paradigms of this age.Template:Sfn

Speech, in the form of polemical rhetoric, was the main form of violence.Template:Sfn Template:Sfn Argument centered on the true meaning of "logos". Pagans asserted logos could be found in ancient myths and poetics as allegory.Template:Sfn Christian responses formed their first true ontologies, distinct from earlier apologetics, asserting the Christian logos.Template:Sfn Template:Sfn However, the primary focus of biblical commentators between 300 and 600 was not on polemical responses to pagans but on aiding ordinary Christians whose primary concern was sin and salvation.Template:Sfn Template:Sfn Christian baptism was distinctive and demonstrated how Christians understood these concepts in terms of the death of Christ.Template:Sfn As theology evolved, it held to the paradox of God’s incarnation, as well as the decisive human contribution to redemption seen in Jesus Christ as "the new human being, who is God".Template:Sfn

Before the fourth century, Judaism had been an approved religion, while Christianity was persecuted as an illegal superstition; during the fourth century, Christianity became favored by emperors and Judaism came to be seen as a heresy.Template:Sfn Still, Augustine of Hippo argued that Jews should not be killed or forcibly converted; they should be left alone because they preserved the teachings of the Old Testament and were "living witnesses" of the New Testament.Template:Sfn Aside from the Visigothic Kingdom, Jews and Christians peacefully coexisted, for the most part, into the High Middle Ages.Template:Sfn Template:Sfn Template:Refn

Constantine and his successors attempted to fit the church into their political program.Template:Sfn Church leaders responded with the first fully articulated limitation on secular authority based on the church as a separate entity, arguing that the church was not part of the empire so much as the empire was part of the universal church.Template:Sfn During this period, the successors to Peter as Bishop of Rome (known as the Pope) had limited influence, and they lacked the power to break free of secular involvement in church affairs. However, papal influence rose as eastern patriarchs looked to the Pope to resolve disagreements.Template:Sfn Template:Sfn Template:Sfn

Geographical spread

Template:Further Christianity grew rapidly throughout this period.Template:Sfn Template:Sfn Christians in Persia, (present-day Iraq), were deeply persecuted in Late Antiquity, but their numbers still grew. A form of Christianity made inroads among Arabs in Palestine, Yemen, and Arabia.Template:Sfn In the fourth century the percentage of Christians was as high in the Sasanian Empire as in the Roman Empire.Template:Sfn Even as the Huns, Ostrogoths, Visigoths, and Vandals caused havoc in the Roman Empire in the fourth and fifth centuries, many of them converted to Christianity.Template:Sfn Template:Sfn Template:Sfn Syria was home to a thriving theological school.Template:Sfn Template:Sfn The gospel was first brought to Central Asia and China by Syriac-speaking missionaries.Template:Sfn

Christian institutions in Asia or East Africa never developed the kind of influence that the European churches and Byzantium held.Template:Sfn Even so, in 301, the Kingdom of Armenia became the first nation to adopt Christianity as its state religion, soon followed by Caucasian Albania and the East African Kingdom of Aksum.Template:Sfn Template:Sfn Template:Sfn Christianity, a minority faith in Britain since the second century,Template:Sfn began to be displaced by Anglo-Saxon paganism in the fifth century.Template:Sfn However, this process began reversing after the Gregorian mission of 597,Template:Sfn and in the early fifth century, missionaries began conversions in Ireland as well.Template:Sfn

Heresies, schisms and councils

Regional variants of Christianity produced diverse and sometimes competing theologies.Template:Sfn Template:Sfn Ancient Christian authors identified any practice or doctrine which differed from apostolic tradition as heresy.Template:Sfn Template:Sfn Template:Sfn The number of laws directed at heresy indicate it was a much higher priority than paganism for Christians of this period.Template:Sfn Template:Sfn

For decades, Arianism embroiled the entire church, laity (non-clergy) and clergy alike, in arguing whether Jesus' divinity was equal to the Father's.Template:Sfn Template:Sfn Template:Sfn The First Council of Nicaea in 325 attempted to resolve the controversy with the Nicene Creed, but some refused to accept it.Template:Sfn Template:Sfn The development of heresy demonstrated the importance of boundaries, which became a force for social stability through cultural assimilation.Template:Sfn Along the Eastern Mediterranean, where Christian factions struggled without resolution, Christian communities were weakened, affecting their long-term survival.Template:Sfn

Christian scriptures were formalized as the New Testament and distinguished from the Old Testament by the fourth century.Template:Sfn Template:Sfn Despite agreement on these texts, differences between East and West were becoming evident.Template:Sfn Template:Sfn Template:Sfn The West was solidly Nicean while the East was largely Arian.Template:Sfn The West condemned Roman culture as sinful and resisted state control, whereas the East harmonized with Greek culture and aimed for unanimity between church and state.Template:Sfn Template:Sfn Template:Sfn The marriage of clerics was accepted in the East but forbidden in the West.Template:Sfn Template:Sfn The East advocated sharing the government of the church between five church leaders, arguing that the Patriarchs of Constantinople, Alexandria, Antioch, and Jerusalem were equal to the Pope. Rome asserted that successors to Peter had superiority.Template:Sfn Template:Sfn

Controversies over how Jesus' human and divine natures coexisted peaked when Nestorius declared Mary as the mother of Jesus' humanity, not his divinity, thereby giving Jesus two distinct natures.Template:Sfn This led to a series of ecumenical councils: the Council of Ephesus was the church's third council, and it condemned Nestorius. Held in 431, the church in the Persian Empire refused to recognize its authority. This led to the first separation between East and West. Two groups, one mostly Persian and the other Syrian, separated from Catholicism; Persians became the Church of the East (also known as the Assyrian, Nestorian, or Persian Church), while the majority of Christians in Syria and Mesopotamia became the Syrian Orthodox Church (Jacobite).Template:Sfn Template:Refn This cut off the flourishing school of Syrian Semitic Christian theologians and writers from the rest of Christendom.Template:Sfn The Church of the East lay almost entirely outside the Byzantine Empire.Template:Sfn It became the principal Church in Asia in the Middle Ages.Template:Sfn

In 451, the fourth council was the influential Council of Chalcedon.Template:Sfn Template:Refn While most of Christianity accepted the Chalcedonian Definition, which emphasizes that the Son is "one person in two natures," there were those who found that description too close to the duality of Nestorianism, so after 484, they separated into Oriental Orthodoxy that sees only "One Nature of God the Incarnate Logos".Template:Sfn Template:Sfn Template:Sfn

After 476

For the five centuries after the fall of the Western Roman Empire in 476, Western culture and civilization were primarily preserved and passed on by monks.Template:Sfn Template:Sfn Template:Sfn Those in the Eastern Roman Empire continued to see themselves as a Roman Empire with an emperor, a civil government, and a large army.Template:Sfn Template:Sfn Template:Sfn Template:Sfn

The religious policies of the Eastern Roman Emperor Justinian I (Template:Reign) reflected his conviction that the unity of the Empire presupposed unity of faith: he persecuted pagans and religious minorities, purging the government and church bureaucracies of those who disagreed with him.Template:Sfn Template:Sfn Justinian contributed to cultural development,Template:Sfn and integrated Christian concepts with Roman law in his Template:Lang, which remains the basis of civil law in many modern states.Template:Sfn Template:Sfn

In Gaul, the Frankish king Clovis I converted to Catholicism; his kingdom became the dominant polity in the West in 507, gradually converting into a Christian kingdom over the next centuries.Template:Sfn Template:Sfn Papal influence rose as the church leaders increasingly relied on Rome to resolve theological disagreement.Template:Sfn Template:Sfn Pope Gregory I gained prestige and power for the papacy by leading the response to invasion by the Lombards in 592 and 593, reforming the clergy, standardizing music in worship, sending out missionaries, and founding new monasteries.Template:Sfn Template:Sfn Until 751, the Pope remained a subject of the Byzantine emperor.Template:Sfn

Early Middle Ages (c. 600–1000)

Template:Further Template:See also By the early 600s, Christianity had spread around the Mediterranean.Template:Sfn However, between 632 and 750, Islamic caliphates conquered the Middle East, North Africa, and the Iberian Peninsula.Template:Sfn Template:Sfn Template:Sfn Most urban Asian churches disappeared, but Christian communities established in remote areas between the fifth and the eighth centuries continued to survive.Template:Sfn Template:Sfn In the same period, war on multiple fronts contributed to the Eastern Roman Empire becoming the independent Byzantine Empire.Template:Sfn Until the eighth century, most of Western Europe remained largely impoverished, politically fragmented, and dependent on the church.Template:Sfn Template:Sfn

During this period, invasion, deportation, and governmental neglect left many communities without a church, leaving Christianity to syncretize with local pagan traditions.Template:Sfn Template:Sfn The church of this age was only indirectly influenced by the Bible.Template:Sfn Nevertheless, "Christendom," the notion of all Christians united as a polity, emerged at the end of this age.Template:Sfn Template:Sfn

Monasticism and art

Until the end of the Early Middle Ages, Western culture was preserved and passed on primarily by monks known as "regular clergy" because they followed a Template:Lang: a rule.Template:Sfn Template:Sfn The rule included chastity, obedience and poverty sought through prayer, memorization of scripture, celibacy, fasting, manual labour, and almsgiving.Template:Sfn Template:Sfn

Monasteries served as orphanages and inns for travelers, and they provided food for those in need.Template:Sfn Template:Sfn Template:Sfn They supported literacy, practiced classical arts and crafts, and copied and preserved ancient texts in their scriptoria and libraries.Template:Sfn Template:Sfn Dedicated monks created illuminated manuscripts.Template:Sfn From the sixth to the eighth centuries, most schools were connected to monasteries, but methods of teaching an illiterate populace could also include mystery plays, vernacular sermons, saints' lives in epic form, and artwork.Template:Sfn Template:Sfn Template:Sfn

This was an age of uncertainty, and the role of relics and holy men able to provide special access to the divine became increasingly important.Template:Sfn Template:Sfn Promoting that special access, church offers that donations would fund prayers for the dead provided an ongoing source of wealth.Template:Sfn Template:Sfn Monasteries became increasingly organized, gradually establishing their own authority as separate from political and familial authorities, thereby revolutionizing social history.Template:Sfn Template:Sfn Medical practice was highly important, and medieval monasteries were best known for their public hospitals, hospices, and contributions to medicine.Template:Sfn Template:Sfn The sixth-century Rule of Saint Benedict has had extensive influence.Template:Sfn Template:Sfn Template:Sfn

The East developed an approach to sacred art unknown in the West, adapting ancient portraiture in icons as intercessors between God and humankind.Template:Sfn In the 720s, the Byzantine Emperor Leo banned the pictorial representation of Christ, saints, and biblical scenes, and destroyed much early representational art.Template:Sfn The West condemned the Byzantine iconoclasm of Leo and some of his successors.Template:Sfn By the tenth and early eleventh centuries, Byzantine culture began to recover its artistic heritage.Template:Sfn Template:Sfn

Regional differences

Eastern Europe had been exposed to Christianity during Roman rule, but it was Byzantine Christianity, brought by the ninth-century saints Cyril and Methodius, that was integral to the formation of its modern states. Dukes and kings used the new faith to solidify their position and promote unity, while some directly enforced it with new laws, building churches, and establishing monasteries.Template:Sfn Template:Sfn Template:Sfn The brothers developed the Glagolitic alphabet to translate the Bible into the local language. Their disciples then developed the Cyrillic script, which spread literacy and became the cultural and religious foundation for all Slavic nations.Template:Sfn Template:Sfn Template:Sfn

In 635, the Church of the East brought Christianity to the Chinese Emperor Taizong whose decree to license the Christian faith was copied onto the Sianfu stele.Template:Sfn It spread into northwestern China, Khotan, Turfan, and south of Lake Balkash in southeastern Kazakhstan, but its growth was halted in 845 by Emperor Wu-Tsung, who favoured Taoism.Template:Sfn The Church of the East evangelized all along the Silk Road and was instrumental in converting some of the Mongolic and Turkic peoples.Template:Sfn After 700, when much of Christianity was declining, there were flourishing Christian societies along all the main trade routes of Asia, South India, the Nubian kingdoms, Ethiopia, the Caucasus region.Template:Sfn Template:Sfn

In Western Europe, canon law was instrumental in developing key norms concerning oaths of loyalty, homage, and fidelity.Template:Sfn These norms were incorporated into civil law where traces remain.Template:Sfn Within the tenets of feudalism, the church created a new model of consecrated kingship unknown in the East, and in 800, Clovis' descendant Charlemagne became its recipient when Pope Leo III crowned him emperor.Template:Sfn Charlemagne engaged in a number of reforms which began the Carolingian Renaissance, a period of intellectual and cultural revival.Template:Sfn His crowning set the precedent that only a pope could crown a Western emperor enabling popes to claim emperors derived their power from God through them.Template:Sfn The Papacy became free from Byzantine control, and the former lands of the Exarchate became States of the church.Template:Sfn Template:Sfn However, the papacy was still in need of aid and protection, so the Holy Roman emperors often used that need to attempt domination of the Papacy and the Papal States.Template:Sfn In Rome, the papacy came under the control of the city's aristocracy.Template:Sfn Template:Sfn

In Russia, the baptism of Vladimir of Kiev in 989 is traditionally associated with the conversion of the Kievan Rus'.Template:Sfn Their new religious structure included dukes maintaining control of a financially-dependent church.Template:Sfn Template:Sfn Template:Refn Monasticism was the dominant form of piety for both peasants and elites who identified as Christian while retaining many pre-Christian practices.Template:Sfn

Viking raids in the ninth and tenth centuries destroyed many churches and monasteries, inadvertently leading to reform. Patrons competed in rebuilding so that "by the mid-eleventh century, a wealthy, unified, better-organized, better-educated, more spiritually sensitive Latin Church" resulted.Template:Sfn There was another rise in papal power in the tenth century when William IX, Duke of Aquitaine, and other powerful lay founders of monasteries, placed their institutions under the protection of the papacy.Template:Sfn Template:Sfn Template:Sfn

High Middle Ages (c. 1000–1300)

Template:Further Membership in the Christendom of this age began with baptism at birth.Template:Sfn Template:Sfn Template:Sfn Every follower was supposed to have some knowledge of the Apostles' Creed and the Lord's Prayer, to rest on Sunday and feast days, attend mass, fast at specified times, take communion at Easter, pay various fees for the needy, and receive last rites at death.Template:Sfn Template:Sfn The medieval papacy gained authority in every domain of European life as it gradually came to resemble the monarchies of its day.Template:Sfn Template:Sfn

Canon law became a huge, highly complex legal system, and yet these hundreds of laws largely omitted Christianity's earlier principles of equity and inclusivity.Template:Sfn Template:Sfn The High Middle Ages saw the formation of several fundamental Christian doctrines, such as the seven sacraments, the just reward for labour, "the terms of Christian marriage, the nature of clerical celibacy and the appropriate lifestyle for priests".Template:Sfn Heresy was more precisely defined.Template:Sfn Purgatory became an official doctrine. In 1215, confession became required for all.Template:Sfn Template:Sfn The rosary was created after veneration of Mary, mother of Jesus became a central aspect of the period.Template:Sfn

Beginning at Cluny Abbey (910), which used Romanesque architecture to convey a sense of awe and wonder and inspire obedience, monasteries gained influence through the Cluniac Reforms.Template:Sfn Template:Sfn Template:Refn However, their cultural and religious dominance began to decline in the mid-eleventh century when secular clergy, who were not members of religious orders, rose in influence.Template:Sfn Monastery schools lost influence as cathedral schools spread,Template:Sfn independent schools arose,Template:Sfn and universities formed as self-governing corporations chartered by popes and kings.Template:Sfn Template:Sfn Canon and civil law became professionalized, and a new literate elite formed, further displacing monks.Template:Sfn Template:Sfn Throughout this period, the clergy and the laity became "more literate, more worldly, and more self-assertive".Template:Sfn Template:Refn

Centralization

The reform of Pope Gregory VII (1073–1085) began "a new period in church history".Template:Sfn Template:Sfn Previously, the power of kings and emperors had been at least partly founded on connection to the sacred.Template:Sfn Template:Sfn Gregorian Reform intended to divest Western rule of its sacramental character, and to establish the preeminence of the church by freeing it from state control.Template:Sfn This reinforced the popes' temporal power, enabling a reorganization of the administration of the Papal States which brought a substantial increase in wealth. This enabled popes to become patrons in their own right,Template:Sfn Template:Sfn Template:Sfn consolidate territory, centralize authority, and establish a bureaucracy.Template:Sfn Template:Sfn Template:Sfn

The centralization of governance during this period created conflict between church and state officials competing to claim legal and tax jurisdiction over the same populace.Template:Sfn Template:Sfn A major example was the Investiture Controversy in the Holy Roman Empire, a conflict between the Holy Roman Emperor Henry IV and Pope Gregory VII over the secular appointment of bishops and abbots and control of their revenues.Template:Sfn Template:Sfn Template:Sfn Template:Sfn For the church, ending lay investiture would support independence from the state, encourage reform, and provide better pastoral care. For the kings, ending lay investiture meant the power of the Holy Roman Emperor and the European nobility would be reduced.Template:Sfn Template:Sfn Template:Sfn Template:Sfn

The Template:Lang of 1075 declared that the pope alone could invest bishops.Template:Sfn Disobedience to the Pope became equated with heresy;Template:Sfn when Henry IV rejected the decree, he was excommunicated, which contributed to a civil war.Template:Sfn Template:Sfn Template:Sfn A similar controversy occurred in England.Template:Sfn

Schism, crusade, spread, and retraction

The Church of the East, which had separated after Chalcedon, survived against the odds with help from Byzantium.Template:Sfn At the height of its expansion in the thirteenth century, the Church of the East stretched from Syria to eastern China and from Siberia to southern India and southern Asia.Template:Sfn The second separation between east and west took place in 1054 when the church within the Byzantine Empire formed Byzantine Eastern Orthodoxy, which thereafter remained in communion with the Ecumenical Patriarchate of Constantinople, not the Pope.Template:Sfn

Along with geographical separation, there had long been many cultural differences, geopolitical disagreements, and a lack of respect between east and west.Template:Sfn Template:Sfn Nevertheless, the Byzantine emperor Alexios I Komnenos still asked Pope Urban II for help with the Seljuk Turks in 1081,Template:Sfn and Urban asked European Christians to "go to the aid of their brethren in the Holy Land" in 1095.Template:Sfn Template:Sfn Template:Sfn

Urban's message had great popular appeal. Drawing on powerful and prevalent aspects of folk religion, the First Crusade connected pilgrimage, charity, and absolution with a willingness to fight.Template:Sfn Template:Sfn It gave ordinary Christians a tangible means of expressing brotherhood with the East and carried a sense of historical responsibility.Template:Sfn The Crusades contributed to the development of national identities in European nations and, eventually, increased division with the East.Template:Sfn The evolving cult of chivalry of the Christian knight became a powerful social and cultural influence before its decline during the 1400s.Template:Sfn Template:Sfn One significant effect of the Crusades was the invention of the indulgence.Template:Sfn

Christianity was declining in Mesopotamia and inner Iran, although some Christian communities continued to exist further to the east.Template:Sfn Template:Sfn As churches in Egypt, Syria, and Iraq became subject to fervently Islamic militaristic regimes, Christians were designated as dhimmi, a status that guaranteed their protection but enforced their legal inferiority.Template:Sfn Different communities adopted various survival strategies: some withdrew from interaction, others converted to Islam, and others sought outside help.Template:Sfn

The Christianization of Scandinavia occurred in two stages: first, in the ninth century, missionaries operated without secular support; then, a secular ruler would begin to oversee Christianization in their territory until an organized ecclesiastical network was established.Template:Sfn By 1350, Scandinavia was an integral part of Western Christendom.Template:Sfn

Renaissance, science and technology

The Christian wars of reconquest, which lasted over 200 years, had begun in Italy in 915 and in Spain in 1009 to retake territory lost to Muslims, causing fleeing Muslims in Sicily and Spain to leave behind their libraries.Template:Sfn Between 1150 and 1200, monks searched those libraries and found the works of Aristotle, Euclid, and other ancient writers.Template:Sfn The West's rediscovery of the complete works of Aristotle led to the Renaissance of the twelfth century. It also created conflict between faith and reason, resolved by a revolution in thought called scholasticism.Template:Sfn Template:Sfn The scholastic writings of Thomas Aquinas impacted Catholic theology and influenced secular philosophy and law into the modern day.Template:Sfn Template:Sfn Template:Sfn Monks revived the scientific study of natural phenomena, which led to the scientific revolution in the West.Template:Sfn Template:Sfn Template:Sfn There was no parallel renaissance in the East.Template:Sfn

Byzantine art exerted a powerful influence on Western art in the twelfth and thirteenth centuries.Template:Sfn Gothic architecture, intended to inspire contemplation of the divine, began in the same centuries.Template:Sfn Template:Sfn The Cistercian movement was a wave of monastic reform after 1098; Cistercians became instrumental in technological advancement in medieval Europe.Template:Sfn Template:Sfn Template:Sfn

Challenges and repression

The twelfth century saw a change in the goal of a monk from contemplative devotion to active reform.Template:Sfn Template:Sfn Among these new activist preachers was Dominic who founded the Dominican Order and was significant in opposing Catharism.Template:Sfn Template:Sfn In 1209, Pope Innocent III and King Philip II of France initiated the Albigensian Crusade against Catharism.Template:Sfn Template:Sfn The campaign took a political turn when the king's army strategically seized and occupied lands of nobles who had not supported the heretics, but had been in the good graces of the Church.Template:Sfn It ended in 1229 when the region was brought under the rule of the French king, creating southern France, while Catharism continued until 1350.Template:Sfn Template:Sfn

Moral misbehaviour, such as sexual misconduct, being drunk and disorderly in public, or heresy by either laity or clergy, were prosecuted in inquisitorial courts. These courts were established when someone was accused, then after prosecution, courts were dissolved. Inquisitorial courts were composed of both church and civil authorities.Template:Sfn Template:Sfn Template:Sfn Though these courts had no joint leadership nor joint organization, the Dominican Order held the primary responsibility for conducting inquisitions.Template:Sfn Template:Sfn Template:Sfn The Medieval Inquisition brought between 8,000 and 40,000 people to interrogation and sentencing; death sentences were relatively rare.Template:Sfn The penalty imposed most often was an act of penance which might include public confession.Template:Sfn Bishops were the lead inquisitors, but they did not possess absolute power, nor were they universally supported.Template:Sfn Template:Sfn Inquisition became stridently contested as public opposition grew and riots against the Dominicans occurred.Template:Sfn Template:Sfn Template:Sfn The Fourth Lateran Council of 1215 empowered inquisitors to search out moral and religious "crimes" even when there was no accuser. In theory, this granted them extraordinary powers. In practice, without sufficient local secular support, their task became so overwhelmingly difficult that inquisitors were endangered and some were murdered.Template:Sfn

From 1170-80, the Jewish philosopher Moses ben Maimon (commonly known as Maimonides) wrote his fourteen-volume code of Jewish law and ethics, titled the "Mishneh Torah".Template:Sfn A turning point in Jewish-Christian relations occurred when the Talmud was put "on trial" in 1239 by the French King Louis IX and Pope Gregory IX because of contents that mocked the central figures of Christianity.Template:Sfn Talmudic Judaism came to be seen as so different from biblical Judaism that old Augustinian obligations to leave the Jews alone no longer applied.Template:Sfn Template:Sfn Template:Sfn A rhetoric with elaborate stories casting Jews as enemies accused of ritual murder, blood libel, and desecration of the Christian eucharist host grew among ordinary folk. The spread of the Black Death led to attacks on Jewish communities by people who blamed them for the epidemic.Template:Sfn Template:Sfn Template:Sfn Jews often acted as financial agents for the nobility, providing them loans with interest while being exempt from certain financial obligations. This attracted jealousy and resentment.Template:Sfn Count Emicho of Leiningen massacred Jews in search of supplies and protection money, while the York massacre of 1190 also appears to have originated in a conspiracy by local leaders to liquidate their debts.Template:Sfn

The nobility of Eastern Europe prioritized subduing the Balts, the last major polytheistic population in Europe, over crusading in the Holy Land.Template:Sfn Template:Refn In 1147, the Divina dispensatione gave these nobles indulgences for the first of the Northern Crusades, which intermittently continued, with and without papal support, until 1316.Template:Sfn Template:Sfn Template:Sfn The clergy pragmatically accepted the forced conversions the nobles perpetrated despite continued theological emphasis on voluntary conversion.Template:Sfn

Division in the West

The many calamities of the "long fourteenth century" included plague, famine, wars, and social unrest, leading European people to believe that the end of the world was imminent.Template:Sfn Template:Sfn Template:Sfn This belief ran throughout society and became intertwined with anti-clerical and anti-papal sentiments.Template:Sfn Template:Sfn Template:Refn Criticism of the church became an integral part of late medieval European life, and was expressed in both secular and religious writings, and movements of heresy or internal reform,Template:Sfn Template:Sfn although most attempts at reform between 1300 and 1500 failed.Template:Sfn Template:Sfn Template:Refn

In 1309, Pope Clement V fled Rome's factional politics by moving to Avignon in southern France. By leaving Rome the seat of Peter behind, this Avignon Papacy, consisting of seven successive popes, unintentionally diminished papal prestige and power.Template:Sfn Template:Sfn Pope Gregory XI returned to Rome in 1377.Template:Sfn Template:Sfn Template:Sfn After Gregory's death the following year, the papal conclave elected Urban VI to succeed him, but the French cardinals disapproved and elected Robert of Geneva instead. This began the Western Schism, during which there was more than one pope.Template:Sfn In 1409, the Council of Pisa's attempted resolution resulted in the election of a third separate pope. The schism was finally resolved in 1417, with the election of Pope Martin V.Template:Sfn Template:Sfn

Throughout the Late Middle Ages, the church faced powerful challenges and vigorous political confrontations.Template:Sfn Template:Sfn The English scholastic philosopher John Wycliffe (1320–1384) urged the church to again embrace simplicity by giving up its property and wealth, ending subservience to secular politics, and denying papal authority.Template:Sfn Template:Sfn Wycliffe's teachings were condemned as heresy, but he was allowed to live out the last two years of his life in his home parish.Template:Sfn In 1382, Wycliffe created the first English translation of the Bible.Template:Sfn Wycliffe's teachings influenced the Czech theologian Jan Hus (1369–1415) who also spoke out against what he saw as corruption in the church.Template:Sfn Hus was convicted of heresy and burned at the stake.Template:Sfn This was the impetus for the Bohemian Reformation and led to the Hussite Wars.Template:Sfn Template:Sfn Template:Sfn

Meanwhile, a vernacular religious culture called the Devotio Moderna attempted to work toward a pious society of ordinary people.Template:Sfn Through the Dutch scholar Desiderius Erasmus Roterodamus (1466–1536), Christian humanism grew and impacted literature and education.Template:Sfn Between 1525 and 1534, William Tyndale used the Vulgate and Greek texts from Erasmus to create the Tyndale Bible.Template:Sfn King James commissioned the King James Version in 1604, using all previous versions in Latin, Greek, and English as sources. It was published in 1611.Template:Sfn

East and Renaissance

A reunion agreement between the Orthodox and Catholic churches in 1452 was negated by the Fall of Constantinople to the Ottoman Empire in 1453, which sealed off Orthodoxy from the West for more than a century.Template:Sfn Template:Sfn Template:Sfn Islamic law did not acknowledge the Byzantine church as an institution, but a concern for societal stability allowed it to survive. Financial handicaps, constant upheaval, simony, and corruption impoverished many, and made conversion an attractive solution.Template:Sfn Template:Sfn Template:Sfn This led to the state confiscating churches and turning them into mosques.Template:Sfn The patriarchate became a part of the Ottoman system under Suleiman the Magnificent (1520–1566),Template:Sfn Template:Sfn and by the end of the sixteenth century, widespread desperation and low morale had produced crisis and decline. When Cyril I Loukaris (1572 – 1638) became Patriarch in 1620, he began leading the church toward renewal.Template:Sfn A shared hostility towards Catholicism led Cyril to reach out to the Protestants of Europe and to be deeply impacted by their Reformation doctrines.Template:Sfn Protestant pressure produced the Lukaris Confession embracing Calvinism.Template:Sfn

The flight of Eastern Christians from Constantinople, as well as the manuscripts they carried with them, were important factors in stimulating literary renaissance in the West.Template:Sfn Template:Sfn The Catholic Church became a leading patron of art and architecture, commissioning work and supporting renowned artists.Template:Sfn Template:Sfn Even while fifteenth-century popes struggled to reestablish papal authority, the Renaissance Papacy transformed Rome by rebuilding St. Peter's Basilica and establishing the city as a prestigious centre of learning.Template:Sfn Reformation Protestants condemned these popes as corrupt for their lack of chastity, nepotism, and selling "hats and indulgences".Template:Sfn

In Russia, Ivan III of Russia adopted the style of the Byzantine imperial court to gain support among the Rus' elite who saw themselves as the new 'chosen' and Moscow as the New Jerusalem.Template:Sfn Jeremias II (1536–1595), the first Orthodox patriarch to visit north-eastern Europe, founded the Orthodox Patriarchate of Russia during his journey.Template:Sfn Template:Sfn

The sixteenth-century success of Christianity in Japan was followed by severe repression, such as the crucifixion of the 26 Martyrs of Japan.Template:Sfn Template:Sfn Template:Sfn

Colonialism and missions

Template:Main Template:See also Colonialism, which began in the fifteenth century, originated either on a militaristic/political path, a commercial one, or with settlers who wanted land.Template:Sfn Christian missionaries soon followed with their own separate agenda.Template:Sfn Template:Sfn Template:Sfn Template:Sfn "Companies, politicians, missionaries, settlers, and traders rarely acted together" and were often in conflict.Template:Sfn Some missionaries supported colonialism while others took stances against colonial oppression.Template:Sfn Template:Sfn Template:Sfn Template:Sfn

Between 1500 and 1800, Catholic Christianity gained followers worldwide through missionaries from the Spanish, Portuguese, and French empires.Template:Sfn Template:Sfn Template:Sfn During the Hispanic colonization of the Americas, Latin America largely became a New World form of Iberian Catholicism, while the merging of native and Spanish traditions also created a multitude of indigenous Christianities.Template:Sfn Template:Sfn Spanish missionaries tried to suppress the trade in Amerindian slaves in the Caribbean, but the Catholic church became one of the largest holders of black slaves.Template:Sfn

Long before the first European colonists arrived, indigenous Christian communities, which were often in conflict with the newcomers, had existed in Asia and Africa.Template:Sfn Prior to the Portuguese' landing, St.Thomas Christian communities in southern India had existed continuously for more than 1000 years.Template:Sfn In the 16th century, baptized Kongolese Christians were taken by Portuguese slavers to the Caribbean and Brazil where there are clear traces that they evangelized among their fellow sufferers. Former slaves returned to West Africa "with Bible in hand" preceding the European Protestant missionaries. These freedmen founded Freetown which played a central role in the Christianization of West Africa.Template:Sfn

In the seventeenth and eighteenth centuries, reductionist villages for natives in regions of Paraguay, Argentina, and Brazil were established by Jesuits and other orders. Jesuits promoted local skills and technical innovations, working exclusively in the native language to form an "agrarian collective" kept separate from the rest of colonial society, with serfdom and forced labor forbidden. The Spanish crown resented this autonomy, and the Jesuit order was banned; its members were expelled from Spain in 1767. Thereafter, reduction territories became open to settlers, and natives often became bondmen.Template:Sfn Template:Refn

Women, witch frenzy, expulsion and inquisition

Template:See also Women in the Middle Ages were considered incapable of moral judgment and authority.Template:Sfn Template:Refn However, there were women who became distinguished leaders of nunneries, exercising the same powers and privileges as their male counterparts, such as Hildegard of Bingen (d. 1179), Elisabeth of Schönau (d. 1164/65), and Marie d'Oignies (d. 1213).Template:Sfn Template:Sfn Although the Catholic Church had long ruled that witches did not exist, the conviction that witches were both real and malevolent developed throughout fifteenth-century European society.Template:Sfn Template:Sfn No single cause of "witch frenzy" is known, although the Little Ice Age is thought to have been a factor.Template:Sfn Approximately 100,000 people, of whom 80% were women accused by those in their own villages, were prosecuted in mostly civil trials between 1561 and 1670; 40,000 to 50,000 were executed.Template:Sfn Template:Sfn

The medieval church never officially repudiated Augustine's doctrine of protecting the Jews. However, defining them as heretical outsiders became increasingly common in European society of the fifteenth century as the newly centralized states demanded greater cultural conformity from their citizens.Template:Sfn Template:Sfn Local rulers repeatedly evicted Jews from their lands and confiscated Jewish property.Template:Sfn Template:Sfn Template:Sfn

Between 1478 and 1542, the Spanish and Portuguese inquisitions were initially authorized by the church but soon became state institutions.Template:Sfn Template:Sfn Template:Sfn Authorized by Pope Sixtus IV in 1478, the Spanish Inquisition was established to combat fears that Jewish converts were conspiring with Muslims to sabotage the new state.Template:Sfn Template:Sfn Five years later, a papal bull conceded control of the Spanish Inquisition to Spanish monarchs, making it the first national, unified, centralized institution of the nascent Spanish state.Template:Sfn Template:Sfn Template:Sfn The monarchy centralized state power by absorbing military orders, adapting police organizations and the Inquisition for political purposes.Template:Sfn The Portuguese Inquisition, controlled by a state board of directors, incorporated anti-Judaism before the end of the fifteenth century. Many of these forcibly converted Jews, known as New Christians, fled to Portuguese colonies in India, where they subsequently suffered as targets of the Goa Inquisition.Template:Sfn Template:Sfn The bureaucratic and intellectual Roman Inquisition, best known for its condemnation of Galileo, served the papacy's political aims in Italy.Template:Sfn

Reformation

Template:Multiple image Supported by secular and canon law, the fourteenth century had been among the most violently oppressive of times in Western Europe for minorities.Template:Sfn Template:Sfn Protests against several church practices led to the Protestant Reformation which began when the Catholic monk Martin Luther nailed his Ninety-five Theses to the church door in Wittenberg in 1517. Luther challenged the nature of the church's role in society and its authority.Template:Sfn Template:Sfn For Catholics, authority meant the Pope. For the protesters, authority was in the priesthood of believers and Scripture.Template:Sfn Edicts issued at the Diet of Worms in 1521 condemned Luther.Template:Sfn Template:Sfn

After protracted and acrimonious struggle, three new religious traditions emerged alongside Roman Catholicism: the Lutheran, Reformed, and Anglican traditions.Template:Sfn Template:Sfn For Luther, the church's role in society was determined by two realms of human existence, the secular and the sacred, where one is not allowed to dominate the other, and only secular authority has the right to use force.Template:Sfn Template:Sfn The Reformed churches, formed by followers of theologian John Calvin, argued that the church had the right to function without interference from the state, and they established the ideal of a constitutional representative government in both the church and in society.Template:Sfn Template:Sfn Puritans and other Dissenter groups in England, Huguenots in France, “Beggars” in Holland, Covenanters in Scotland who produced Presbyterianism, and Pilgrim Fathers of New England are Reformed churches that trace their theological roots to Calvin.Template:Sfn The Anglican church was first created as the Church of England by Henry VIII (1491 – 1547) who severed it from papal authority and appointed himself Supreme Head of the Church of England. Still, Henry preserved Catholic doctrine and the church's established role in society.Template:Sfn Template:Sfn

The Roman Catholic Church responded in the Counter-Reformation, spearheaded by ten reforming popes between 1534 to 1605. The Council of Trent (1545–1563) denied each Protestant claim, and laid the foundation of modern Catholic policies. New monastic orders were formed, including the Society of Jesus – the "Jesuits" – who adopted military-style discipline and strict loyalty to the Pope.Template:Sfn Template:Sfn Monastic reform also led to the Spanish mystics and the French school of spirituality,Template:Sfn as well as the Uniate church which used Eastern liturgy but recognized the authority of Rome.Template:Sfn

Quarreling royal houses, already involved in dynastic disagreements, became polarized into the two religious camps.Template:Sfn In 1562, France became the centre of a series of wars, of which the largest and most destructive was the Thirty Years' War (1618–1648).Template:Sfn Template:Sfn While some scholars argue that these wars were varieties of the just war tradition for religious liberty and freedom,Template:Sfn most historians argue that the wars were more about nationalistic state-building and economics, and less about religion.Template:Sfn Template:Sfn

Modern period (1650–1945)

Ideological movements

The era of political absolutism followed the breakdown of Christian universalism in Europe.Template:Sfn Abuses from absolutist Catholic kings gave rise to a virulent critique of Christianity that first emerged among the more extreme Protestant reformers in the 1680s as an aspect of the Age of Enlightenment.Template:Sfn Template:Sfn For 200 years, Protestants had been arguing for religious toleration,Template:Sfn Template:Sfn and by the 1690s, secular thinkers were rethinking the state's reasons for persecution, and they too began advocating for religious toleration.Template:Sfn Template:Sfn Concepts of freedom of religion, speech, and thought became established in the West.Template:Sfn Template:Sfn Template:Sfn

Secularisation spread at every level of European society.Template:Sfn Pioneered by Protestants, Biblical criticism advocated historicism and rationalism to make study of the Bible more scholarly and secular in the 1700s.Template:Sfn Template:Sfn Template:Sfn In reaction to rationalism, pietism, a holiness movement within Lutheranism, began in Europe and spread to the Thirteen Colonies where it contributed to the First Great Awakening, a religious revival of the 1700s.Template:Sfn Template:Sfn Template:Sfn Pietist Moravians came to Georgia in 1732 where they influenced John Wesley, an Anglican missionary in Savannah.Template:Sfn Template:Sfn After returning to England, Wesley began preaching in open-air meetings, leading to the creation of the Methodist church.Template:Sfn Template:Sfn Template:Sfn Template:Sfn In the colonies, Presbyterians and Baptists contributed to revival, and to divisions over it, which formed political parties and lent crucial support for the American Revolution.Template:Sfn Template:Sfn Template:Sfn Spurred by Christians of varying sects, Thomas Jefferson adapted his earlier Virginia Statute for Religious Freedom into the First Amendment to the United States Constitution, enshrining a separation of church and state to support religious pluralism.Template:Sfn Template:Sfn

The rise of Protestantism contributed to the conceptualization of human capital,Template:Sfn development of a new work ethic,Template:Sfn the European state system,Template:Sfn modern capitalism in Northern Europe,Template:Sfn and overall economic growth.Template:Sfn However, urbanization and industrialisation created a plethora of new social problems.Template:Sfn Template:Sfn In Europe and North America, both Protestants and Catholics provided massive aid to the poor, supported family welfare, and offered medicine and education.Template:Sfn

During the French Revolution, Jefferson co-authored the 1789 Declaration of the Rights of Man and of the Citizen recognizing freedom of religion, while radical revolutionaries violently sought dechristianization.Template:Sfn Template:Sfn As a result, the Eastern Orthodox Church rejected Enlightenment ideas as too dangerous to embrace.Template:Sfn

Nineteenth and twentieth centuries

The Second Great Awakening - a religious revival of the 1800s–1830s - produced Mormonism, Restorationism, and the Holiness movement.Template:Sfn Mormons preached the restoration of first-century Christianity, upheld millennialism and premillennialism, and sought to create a religious utopia.Template:Sfn Restorationists, such as the Churches of Christ, Jehovah's Witnesses, and Seventh Day Adventists, also focused on restoring practices of the early church, emphasizing baptism as the crucial conversion experience and biblical authority.Template:Sfn Template:Sfn The Holiness movement contributed to the development of Pentecostalism by combining Restorationism with the goal of sanctification defined as a deeper spiritual experience.Template:Sfn

This revival focused on evidencing conversion through active moral reform in areas such as women's rights, temperance, literacy, and the abolition of slavery. The pursuit of women's rights established "prayer, worship, and biblical exegesis as weapons of political warfare",Template:Sfn while the accent on human choice and activism influenced evangelicalism thereafter.Template:Sfn Template:Sfn Template:Sfn Template:Sfn The 300-year-old trans-Atlantic slave trade, in which some Christians had participated, had always garnered moral objections, and by the eighteenth century, individual Quakers, Methodists, Presbyterians, and Baptists began a written campaign against it.Template:Sfn Congregations led by black preachers kept abolitionism alive into the early nineteenth century when some American Protestants organized the first anti-slavery societies.Template:Sfn This ideological opposition eventually ended the trans-Atlantic slave trade, changing economic and human history on three continents.Template:Sfn Template:Sfn

The Third Great Awakening began in 1857 and took root throughout the world, especially in English-speaking countries.Template:Sfn Nineteenth-century Protestant missionaries, many of them women, played a significant role in shaping nations and societies.Template:Sfn Template:Sfn Template:Sfn Template:Sfn They translated the Bible into local languages, generating a written grammar, a lexicon of native traditions, and a dictionary of the local language.Template:Sfn These were used to teach in missionary schools, resulting in the spread of literacy and indigenization.Template:Sfn Template:Sfn Template:Sfn According to historian Lamin Sanneh, Protestant missionaries thus stimulated the "largest, most diverse and most vigorous movement of cultural renewal" in African history.Template:Sfn Template:Sfn Template:Sfn

Liberal Christians embraced seventeenth-century rationalism, but its disregard of faith and ritual in maintaining Christianity led to its decline. Fundamentalist Christianity rose in the early 1900s as a reaction against modern rationalism.Template:Sfn Template:Sfn By 1930, Protestant fundamentalism in America appeared to be dying.Template:Sfn Template:Sfn However, in the second half of the 1930s, a theology against liberalism that also included a reevaluation of Reformation teachings began uniting moderates of both sides.Template:Sfn Template:Sfn

The Roman Catholic Church became increasingly centralized, conservative, and focused on loyalty to the Pope.Template:Sfn As Nazism rose, Pope Pius XI declared the irreconcilability of the Catholic position with totalitarian fascist states that placed the nation above God.Template:Sfn Most leaders and members of the largest Protestant church in Germany, the German Evangelical Church, supported the Nazi Party when they came to power in 1933.Template:Sfn About a third of German Protestants formed the Confessing Church which opposed Nazism; its members were harassed, arrested, and otherwise targeted. In Poland, Catholic priests were arrested and Polish priests and nuns were executed en masse.Template:Sfn

Russian Orthodoxy

The church reform of Peter I of Russia in the early 1700s placed the Orthodox authorities under the control of the emperor. Russian emperors continually involved the church in campaigns of russification, contributing to antisemitism.Template:Sfn Template:Sfn The communist revolutionaries who established the Soviet Union saw the Church as an enemy of the people and part of the monarchy.Template:Sfn Template:Sfn Template:Sfn Template:Sfn The communist Soviet Union heavily persecuted the Russian Orthodox Church,Template:Sfn executing up to 8,000 people by 1922.Template:Sfn The League of Militant Atheists adopted a five-year plan in 1932 "aimed at the total eradication of religion by 1937".Template:Sfn Despite this, the Orthodox Church continued to contribute to theology and culture.Template:Sfn

Global distribution of Christians based on 2011 Pew Research Center dataTemplate:Sfn

Before 1945, about a third of the people in the world were Christians, and about 80% of them lived in Europe, Russia, and the Americas.Template:Sfn In 2025, there are still 31% of adults around the world that declare themselves Christian, but they are no longer concentrated in the West.Template:Sfn Christianity has been in decline in Europe for decades. Between 2010 and 2015, the number of European Christians who died outnumbered births by nearly 6 million.Template:Sfn From 2019 to 2024, the Christian share of the adult population in the United States stayed between 60% and 64%. Even so, it is estimated that fewer than a quarter of the world's Christians will live in its western locations by 2060.Template:Sfn

After WWII, decolonization strengthened the indigenization efforts of Christian missionaries, leading to explosive growth in the churches of former colonies.Template:Sfn Template:Sfn Template:Sfn Template:Sfn In 1900, there were just under nine million Christians in Africa; by 1960, this number had increased to 60 million, and by 2005, to 393 million, about half of the continent's population, a proportion which has remained constant as of 2022.Template:Sfn Template:Sfn Template:Sfn According to PEW, religion is very important to people in Africa, the Middle East, South Asia, and Latin America where populations are growing and are likely to continue to grow.Template:Sfn This is shifting the geographic center of Christianity to sub-Saharan Africa where more than forty percent of the world’s Christians are projected to live by 2060.Template:Sfn

Christianity in Southeast and East Asia, especially Korea, grew faster after colonialism.Template:Sfn Template:Sfn Template:Sfn Rapid expansion began in the 1980s.Template:Sfn Template:Sfn The Council on Foreign Relations reports that the number of Chinese Protestants has grown by an average of 10% annually since 1979, with growth especially prominent among young people.Template:Sfn Template:Sfn Template:Sfn With the Fall of the Eastern Bloc, Christianity expanded in some Eastern European countries while declining in others.Template:Sfn Template:Sfn Template:Sfn Catholic countries have displayed secularization, while Orthodox countries have experienced a revival of church participation.Template:Sfn Orthodox Christianity made a partial resurgence in the former Soviet Union after 1991 and continues to be an important element of national identity for many citizens there.Template:Sfn

In the first quarter of the twenty-first century, Christianity is present in all seven continents and a multitude of different cultures.Template:Sfn Template:Sfn Most Christians live outside North America and Western Europe; white Christians are a global minority, and slightly over half of worldwide Christians are female.Template:Sfn Template:Sfn In 2017, PEW reported that Christianity is the world's largest religion with roughly 2.4 billion followers, equal to 31.2% of the world's population.Template:Sfn Template:Sfn Template:Sfn

Modern movements

In the twentieth century, Christianity faced the challenges of secularism and a changing moral climate concerning sexual ethics, gender, and exclusivity, leading to a decline in church attendance in the West.Template:Sfn Template:Sfn Template:Sfn In a 2018 PEW survey of 27 countries, the majority of nations had more residents claim that the role of religion has decreased over the preceding twenty years than said it had increased. However, people in Southeast Asian and Sub-Saharan African countries reported the opposite trend, suggesting that secularization is a region-specific trend.Template:Sfn Template:Sfn

In 2000, approximately one-quarter of all Christians worldwide were part of Pentecostalism and its associated movements.Template:Sfn By 2025, Pentecostals are expected to constitute one-third of the nearly three billion Christians worldwide, making it the largest branch of Protestantism and fastest-growing Christian movement.Template:Sfn Template:Sfn

The three main branches of Eastern Christianity are the Eastern Orthodox Church, Oriental Orthodox Communion, and Eastern Catholic Church.Template:Sfn Template:Sfn Template:Sfn Roughly half of Eastern Orthodox Christians live in formerly Eastern Bloc countries.Template:Sfn Its oldest communities in Jerusalem, Antioch, Alexandria, Constantinople, and Georgia, are decreasing due to forced migration from religious persecution.Template:Sfn In 2020, 57 countries had “very high” levels of government restrictions on religion, banning or giving preferential treatment to particular groups, prohibiting conversions, and limiting preaching.Template:Sfn Template:Sfn As of 2022, highly authoritarian and totalitarian governments have brought about crises and decline in 186 countries.Template:Sfn Anti-Christian persecution has become a consistent human rights concern.Template:Sfn

Orthodox Christians of the Greek, Russian and Balkans branches tend to be more conservative on most issues than Protestants and Catholics.Template:Sfn Less than 40% of Orthodox Christians favor reconciliation with the Roman Catholic Church.Template:Sfn Roman Catholic ecumenical goals are to re-establish full communion amongst all the various Christian churches, but there is no agreement amongst evangelicals.Template:Sfn Template:Sfn Template:Sfn There is, however, a trend at the local level toward discussion, pulpit exchanges, and shared social action.Template:Sfn Template:Sfn

The multiple wars of the twentieth century brought questions of theodicy to the forefront.Template:Sfn For the first time since the pre-Constantinian era, Christian pacifism became an alternative to war.Template:Sfn The Holocaust forced many to realize that supersessionism, the belief that Christians had replaced the Jews as God's chosen people, can lead to hatred, ethnocentrism, and racism. Supersessionism was never an official doctrine or universally accepted, and supersessionist texts are increasingly challenged.Template:Sfn

For theologians writing after 1945, theology became dependent on context.Template:Sfn Liberation theology was combined with the social gospel, redefining social justice, and exposing institutionalized sin to aid Latin American poor, but its context limited its application in other environments.Template:Sfn Template:Sfn Template:Sfn Different historical and socio-political situations produced black theology and feminist theology. Combining Christianity with questions of civil rights, aspects of the Black Power movement, and responses to black Muslims produced a black theology that spread to the United Kingdom and parts of Africa, confronting apartheid in South Africa.Template:Sfn Template:Sfn The feminist movement of the mid-twentieth century began with an anti-Christian ethos but soon developed an influential feminist theology dedicated to transforming churches and society.Template:Sfn Template:Sfn Feminist theology developed at the local level through movements such as the womanist theology of African-American women, the "mujerista" theology of Hispanic women, and Asian feminist theology.Template:Sfn

In the mid to late 1990s, postcolonial theology emerged globally from multiple sources.Template:Sfn It analyzes structures of power and ideology to recover what colonialism erased or suppressed in indigenous cultures.Template:Sfn

Modern motivation toward missions has declined in some denominations largely from doctrines of inclusivity and polarization over the role of women. Many modern churches bypass missionary agencies sending out individual missionaries from single churches leaving them without extensive support.Template:Sfn The missionary movement of the twenty-first century has become a multi-cultural, multi-faceted global network of NGOs,Template:Sfn volunteer doctors,Template:Sfn short-term student volunteers,Template:Sfn and traditional long-term bilingual, bicultural professionals who focus on evangelism and local development.Template:Sfn Template:Sfn Template:Sfn
