. Christianization has, for the most part, spread through missions by individual conversions, but has also, in some instances, been the result of violence by individuals and groups such as governments and militaries. Christianization is also the term used to designate the conversion of previously non-Christian practices, spaces and places to Christian uses and names. In a third manner, the term has been used to describe the changes that naturally emerge in a nation when sufficient numbers of individuals convert, or when secular leaders require those changes. Christianization of a nation is an ongoing process.

David Abulafia and
Nóra Berend speak of religious activity in relation to the "frontier" regions at the borders of civilizations. Berend sees a frontier as "a contact zone where an interchange of cultures was constantly taking place". In this way, the missionary religions of Buddhism, Islam and Christianity spread themselves geographically, through teaching and preaching, with interaction sometimes producing conflict, and other times ''mingling'' and accommodation.
Alan Neely writes that, "wherever Christianity (or any other faith) is carried from one culture to another, intentionally or not, consciously or not, it is either adapted to that culture or it becomes irrelevant." In his book ''Christian Mission,'' Neely provides multiple historical examples of adaptation, accommodation, indigenization, inculturation, autochthonization and contextualization as the means of successful Christianization through missions. Neely's definitions are these:
* Accommodation is a form of adaptation that occurs when the missionary adjusts their own thinking and vocabulary to keep only what is essential and let go of what is expendable in communicating the faith.
* Indigenization, in this application, refers to taking something that is native to one culture and making it native to another culture; that is, taking Christianity and making it more native by including aspects of native language and practices.
* Autochthonization means the same as indigenization, but is specific to Spanish and Portuguese.
* Inculturation, or acculturation, is the gradual process of adopting aspects of Christianity, but it has often mistakenly been seen as socialization to another culture. Changes of dress, customs and names have sometimes been confused with actual Christianization which involves internal and not simply external changes. Whenever the gospel has been linked to a particular culture,

forcefully insists the result has been subjugation not conversion.
* Contextualization is a way to be faithful to the essence of the message while also being relevant to the people to whom it is being presented. In the 21st century, contextualization has led missions to build daycare centers, wells for clean water, schools, address housing and economic injustice issues and more. It depends on the people being addressed, as well as "geography, language, ethnicity, political and economic systems, class gender and age, time frame, sense of identity, religion, values and history".
Individual conversion
James P. Hanigan writes that individual conversion is the foundational experience and the central message of Christianization, adding that Christian conversion begins with an experience of being "thrown off balance" through cognitive and psychological "disequilibrium", followed by an "awakening" of consciousness and a new awareness of God. Hanigan compares it to "death and rebirth, a turning away..., a putting off of the old..., a change of mind and heart". The person responds by acknowledging and confessing personal lostness and sinfulness, and then accepting a
call to holiness thus restoring balance. This initial internal conversion is only the beginning of Christianization; it is followed by practices that further the process of Christianizing the individual's lifestyle, which according to Hanigan, will include ethical changes.
While Christian theologians such as the fourth century Augustine and the ninth century Alcuin maintained that conversion must be voluntary, there are historical examples of coercion in conversion. Constantine used both law and force to eradicate the practice of sacrifice and repress heresy though not specifically to promote conversion. Theodosius also wrote laws to eliminate heresies, but made no requirement for pagans or Jews to convert to Christianity. However, the sixth century Eastern Roman emperor

was added to the rites of initiation. While baptism, instruction, and Eucharist have remained the essential elements of initiation in all Christian communities, theologian Knut Alfsvåg writes on the differing status of confirmation in different denominations:
Some see baptism, confirmation, and first communion as different elements in a unified rite through which one becomes a part of the Christian church. Others consider confirmation a separate rite which may or may not be considered a condition for becoming a fully accepted member of the church in the sense that one is invited to take part in the celebration of the Eucharist. Among those who see confirmation as a separate rite some see it as a sacrament, while others consider it a combination of intercessory prayer and graduation ceremony after a period of instruction.
Places and practices
Christianization has at times involved appropriation, removal and/or redesignation of aspects of native religion and former sacred spaces. This was allowed, or required, or sometimes forbidden by the missionaries involved. The church adapts to its local cultural context, just as local culture and places are adapted to the church, or in other words, Christianization has always worked in both directions: Christianity absorbs from native culture as it is absorbed into it.

Temple conversion within Roman Empire
R. P. C. Hanson says the direct conversion of temples into churches began in the mid-fifth century but only in a few isolated incidents. According to modern archaeology, of the thousands of temples that existed across the empire, 120 pagan temples were converted to churches with the majority dated after the fifth century. It is likely this stems from the fact that these buildings remained officially in public use, ownership could only be transferred by the emperor, and temples remained protected by law.
In the fourth century, there were no conversions of temples in the city of Rome itself. It is only with the formation of the Papal State in the eighth century, (when the emperor's properties in the West came into the possession of the bishop of Rome), that the conversions of temples in Rome took off in earnest.
According to Dutch historian Feyo L. Schuddeboom, individual temples and temple sites in the city of Rome were converted to churches primarily to preserve their exceptional architecture. They were also used pragmatically because of the importance of their location at the center of town.
Temple and icon destruction
During his long reign (307–337),

Golgotha hill in order to suppress veneration there. Constantine was vigorous in reclaiming such properties whenever these issues were brought to his attention, and he used reclamation to justify the destruction of Aphrodite's temple. Using the vocabulary of reclamation, Constantine acquired several more sites of Christian significance in the Holy Land.
In Eusebius' church history, there is a bold claim of a Constantinian campaign to destroy the temples, however, there are discrepancies in the evidence. Temple destruction is attested to in 43 cases in the written sources, but only four have been confirmed by archaeological evidence. Historians Frank R. Trombley and
Ramsay MacMullen explain that discrepancies between literary sources and archaeological evidence exist because it is common for details in the literary sources to be ambiguous and unclear. For example,
Malalas claimed Constantine destroyed all the temples, then he said
Theodisius destroyed them all, then he said Constantine converted them all to churches.
Additional calculated acts of desecration – removing the hands and feet or mutilating heads and genitals of statues, and "purging sacred precincts with fire" – were acts committed by the common people during the early centuries. While seen as 'proving' the impotence of the gods, pagan icons were also seen as having been "polluted" by the practice of sacrifice. They were, therefore, in need of "desacralization" or "

". Antique historian
Peter Brown says that, while it was in some ways studiously vindictive, it was not indiscriminate or extensive. Once temples, icons or statues were detached from 'the contagion' of sacrifice, they were seen as having returned to innocence. Many statues and temples were then preserved as art. Professor of Byzantine history Helen Saradi-Mendelovici writes that this process implies appreciation of antique art and a conscious desire to find a way to include it in Christian culture.
Aspects of paganism remained part of the
civic culture of the Roman Empire till its end. Public spectacles were popular and resisted Christianization:
gladiatorial combats (''munera''),
animal hunts (''venationes''),
theatrical performances (''ludi scaenici''), and
chariot races (''ludi circenses'') were accommodated by Roman society even while that society disagreed and debated the definition and scope of christianization. Historian of antiquity Richard Lim writes that it was within this process of debate that "the category of the

in the sixth century, though most scholars agree the Empire was never fully Christianized. Archaeologist and historian
Judith Herrin has written in her article on "Book Burning as Purification" that under Justinian, there was considerable destruction. The decree of 528 barred pagans from state office when, decades later, Justinian ordered a "persecution of surviving Hellenes, accompanied by the burning of pagan books, pictures and statues". This took place at the ''Kynêgion''. Herrin says it is difficult to assess the degree to which Christians are responsible for the losses of ancient documents in many cases, but in the mid-sixth century, active persecution in Constantinople destroyed many ancient texts.

I think that the temples of the idols in that nation ought not to be destroyed; but let the idols that are in them be destroyed; let holy water be made and sprinkled in the said temples, and let altars be erected and relics placed. For if those temples are well built, it is requisite that they be converted from the worship of devils to the service of the true God; that the people, seeing that their temples are not destroyed, may remove error from their hearts, and, knowing and adoring the true God, may the more familiarly resort to the places to which they have become accustomed.

about 530, a small temple with a sacred grove and a separate altar to Apollo stood on the hill. The population was still mostly pagan. The land was most likely granted as a gift to Benedict from one of his supporters. This would explain the authoritative way he immediately cut down the groves, removed the altar, and built an oratory before the locals were converted.
Christianization of the Irish landscape was a complex process that varied considerably depending on local conditions. Ancient sites were viewed with veneration, and were excluded or included for Christian use based largely on diverse local feeling about their nature, character, ethos and even location.

n Christianization wrote of dramatic events associated with Christianization in the manner of political propagandists according to who references the 1987 survey by the historian of medieval Scandinavia,
Birgit Sawyer. Sørensen focuses on the changes of names, both personal and place names, showing that cultic elements were not banned and are still in evidence today. Large numbers of pre-Christian names survive into the present day, and Sørensen says this demonstrates the process of Christianization in Denmark was peaceful and gradual and did not include the complete eradication of the old cultic associations. However, there are local differences.
Outside of Scandinavia, old names did not fare as well.

Roman Empire to Early Middle Ages (1 to 800)
Christianization without coercion
There is agreement among twenty-first century scholars that Christianization of the Roman Empire in its first three centuries did not happen by imposition. Christianization emerged naturally as the cumulative result of multiple individual decisions and behaviors.
While enduring three centuries of on-again, off-again persecution, from differing levels of government ranging from local to imperial, Christianity had remained 'self-organized' and without central authority. In this manner, it reached an important
threshold of success between 150 and 250, when it moved from less than 50,000 adherents to over a million, and became self-sustaining and able to generate further growth. There was a significant rise in the absolute number of Christians in the third century.

, and there were no pagan martyrs during his reign. Pagans remained in important positions at his court. Constantine ruled for 31 years and despite personal animosity toward paganism, he never outlawed paganism. Making the adoption of Christianity beneficial was Constantine's primary approach to religion, and imperial favor was important to successful Christianization over the next century. Yet, Constantine did not institute many christianizing changes, and those measures he did enact did little to Christianize civic culture.
According to historian Michelle Renee Salzman, there is no evidence to indicate that conversion of pagans through force was an accepted method of Christianization at any point in Late Antiquity. Evidence indicates all uses of imperial force concerning religion were aimed at heretics (who were already Christian) such as the
Donatists and the
Manichaeans and not at non-believers such as Jews or pagans.
However, Constantine must have written the laws that threatened and menaced pagans who continued to practice sacrifice. The element of pagan culture most abhorrent to Christians was sacrifice, and altars used for it were routinely smashed. Christians were deeply offended by the blood of slaughtered victims as they were reminded of their own past sufferings associated with such altars. Richard Lim writes that "Putting an end to blood sacrifice ... thus became the singular goal of Christianization (Barnes 1984; Bradbury 1994, 1995)".
There is no evidence that any of the horrific punishments included in the laws against sacrifice were ever enacted. There is no record of anyone being executed for violating religious laws before Tiberius II Constantine at the end of the sixth century (574–582). Still, Bradbury notes that the complete disappearance of public sacrifice by the mid-fourth century "in many towns and cities must be attributed to the atmosphere created by imperial and episcopal hostility".

to write that Justinian is often seen as a tyrant and despot. Unlike Constantine, Justinian did purge the bureaucracy of those who disagreed with him. He sought to centralize imperial government, became increasingly autocratic, and according to the historian
Giovanni Mansi, "nothing could be done", not even in the Church, that was contrary to the emperor's will and command. In Kaldellis' estimation, "Few emperors had started so many wars or tried to enforce cultural and religious uniformity with such zeal".

Relying largely on recent archaeological developments, Lorcan Harney has reported to the Royal Academy that the missionaries and traders who came to Ireland in the fifth to sixth centuries were not backed by any military force. Patrick and Palladius and other British and Gaulish missionaries aimed first at converting royal households. Patrick indicates in his ''Confessio'' that safety depended upon it. Communities often followed their king en masse.

Greece
Christianization was slower in Greece than in most other parts of the Roman empire. There are multiple theories of why, but there is no consensus. What is agreed upon is that, for a variety of reasons, Christianization did not take hold in Greece until the fourth and fifth centuries. Christians and pagans maintained a self imposed segregation throughout the period. Historian and archaeologist
Timothy E. Gregory has written in "The Survival of Paganism in Christian Greece: A Critical Essay" that J. M. Speiser successfully argued this was the situation throughout the country, and "rarely was there any significant contact, hostile or otherwise" between Christians and pagans in Greece.
Gregory adds his view that "it is admirably clear that organized paganism survived well into the sixth century throughout the empire and in parts of Greece (at least in the

The king of the country then was the founder of the Arsacid dynasty of Albania Vachagan I the Brave (but not his grandson Urnayr), and the king of Armenia was Tiridat III the Great, also Arsacid. As M. L. Chaumont established in 1969, the latter, with the help of Gregory the Illuminator, adopted the Christian faith at the state level in June 311, two months after the publication of the Edict of Sardica "On Tolerance" by Emperor Galerius (293–311).

Christianization took many generations and was not a uniform process. Byzantine historian Robert Thomson writes that it was not the officially established hierarchy of the church that spread Christianity in Armenia; "It was the unorganized activity of wandering holy men that brought about the Christianization of the populace at large". The most significant stage in this process was the development of a script for the native tongue.

surrendered his Spanish holdings. Sisebut banished all Jews who would not submit to baptism. Roman historian Edmund Spenser Bouchier says 90,000 Hebrews were baptized while others fled to France or North Africa. This contradicted the traditional position of the Catholic Church on the Jews, and scholars refer to this shift as a "seismic moment" in Christianization.
Europe and Asia of the High and Late Middle Ages (800 to 1500)
In Central and Eastern Europe of the 8th and 9th centuries, Christianization was an integral part of the political centralization of the new nations being formed. In Eastern Europe, the combination of Christianization and political centralization created what Peter Brown describes as, "specific micro-Christendoms".

, voluntarily joined the Western, Latin church, sometimes pressuring their people to follow. Full Christianization of the populace often took centuries to accomplish. Conversion began with local elites who wanted to convert because they gained prestige and power through matrimonial alliances and participation in imperial rituals. Christianization then spread from the center to the edges of society.
Historian Ivo Štefan has written, "Although Christian authors often depicted the conversion of rulers as the triumph of the new faith, the reality was much more complex. Christianization of everyday life took centuries, with many non-Christian elements surviving in rural communities until the beginning of the modern era".

Saints Constantine-Cyril and Methodius played the key roles beginning in 863. They spent approximately 40 months in Great Moravia continuously translating texts and teaching students.

and was baptized, bringing home with him Hierotheus who was designated
bishop of Turkia (Hungary). The conversion of Gyula at Constantinople and the missionary work of Bishop Hierotheus are depicted as leading directly to the court of
St. Stephen, the first Hungarian king, a Christian in a still mostly pagan country.
Stephen suppressed rebellion, organized both the Hungarian State (with strong royal authority), and the church, by inviting missionaries, and suppressing paganism by making laws such as requiring people to attend church every Sunday. Soon the Hungarian Kingdom had two archbishops and 8 bishops, and a defined state structure with province governors that answered to the King. Saint Stephen was the first Hungarian monarch elevated to sainthood for his Christian characteristics and not because he suffered a martyr's death. Hungarian Christianity and the kingdom's ecclesiastical and temporal administrations consolidated towards the end of the 11th century.
Scandinavia (Sweden, Norway, Denmark, and Iceland)
Christianization of Scandinavia is divided into two stages by Professor of medieval archaeology
Alexandra Sanmark. Stage 1 involves missionaries who arrived in pagan territory in the 800s, on their own, without secular support. Historian
Florence Harmer writes "Between A.D. 960 and 1008 three Scandinavian kings were converted to Christianity". The Danish King
Harald Gormsen (Bluetooth) was baptized c. 960. The conversion of Norway was begun by
Hákon Aðalsteinsfostri between 935 and 961, but the wide-scale conversion of this kingdom was undertaken by King
Olaf Tryggvason
Olaf Tryggvason (960s – 9 September 1000) was King of Norway from 995 to 1000. He was the son of Tryggvi Olafsson, king of Viken ( Vingulmark, and Rånrike), and, according to later sagas, the great-grandson of Harald Fairhair, first King ...
in c. 995. In Sweden, King
Olof Erikson Skötkonung accepted Christianity around 1000.
According to Peter Brown, Scandinavians adopted Christianity of their own accord c.1000.
Anders Winroth explains that Iceland became the model for the institutional conversion of the rest of Scandinavia after AD 1000. Winroth demonstrates that Scandinavians were not passive recipients of the new religion, but converted to Christianity because it was in their political, economic, and cultural interests to do so.
Stage 2 began when a secular ruler took charge of Christianization in their territory, and ended when a defined and organized ecclesiastical network was established. By 1350, Scandinavia was an integral part of Western Christendom.
Romania
In the last two decades of the 9th century, missionaries
Clement and Naum, (who were disciples of the brothers Cyril and Methodius), had arrived in the region spreading the Cyrillic alphabet. By the 10th century when the Bulgarian Tsars extended their territory to include

, they were able to impose the Bulgarian church model and its Slavic language without opposition. Nearly all Romanian words concerning Christian faith have Latin roots (from the early centuries of Roman occupation), while words regarding the organization of the church are Slavonic.

writes "Christian fervor and the massive conversion to Christianity among the Slavs may have led to the canonic conversion of the last heathen, or ecclesiastically unorganized, Romanian islands". For Romanians, the church model was "overwhelming, omnipresent, putting pressure on the Romanians and often accompanied by a political element". This ecclesiastical and political tradition continued until the 19th century.

and the
Kaliningrad oblast (Prussia). They survived largely by raiding – stealing crucial resources, killing, and enslaving captives – from the countries that surrounded them including Denmark, Prussia, Germany and Poland.
One result of the northern crusades, according to historian Aiden Lilienfeld, was that: "
. . . The conquering forces of the Northern Crusades brought more territory under German control than nearly any other concerted expansion in the history of the
Holy Roman Empire
The Holy Roman Empire, also known as the Holy Roman Empire of the German Nation after 1512, was a polity in Central and Western Europe, usually headed by the Holy Roman Emperor. It developed in the Early Middle Ages, and lasted for a millennium ...
"—emphasizing that duty to the faith could often go hand-in-hand, from the perspective of prospective crusaders, with political and material benefit.
Combining their personal priorities with a need to permanently stop the raiding, they requested permission to subdue the Baltic instead. In 1147, Eugenius' ''
Divini dispensatione,'' gave the eastern nobles full crusade indulgences to do so. The Northern, (or Baltic), Crusades followed, taking place, off and on, with and without papal support, from 1147 to 1316.
Acquisition of territory and wealth was a major aim—perhaps ''the'' major aim—in undertaking military action, on the part of the Christian rulers west of the Oder, and clerics such as
Helmond of Bosau complained that the nobles' demands for tribute hindered the process of conversion; on the other hand, the Christianization of the locals—and the putative rewards in the hereafter to ensue from its success—was a powerful motivator as well. In some cases, voluntary conversion of the local aristocracy—usually followed by the populace, under this influence—was recognized, and stayed the hand of war; in others, naked ambition and greed for material wealth resulted in military actions against ostensibly already-converted peoples. In most cases, conversion was ultimately the result of conquest.
According to Fonnesberg-Schmidt: "While the theologians maintained that conversion should be voluntary, there was a widespread pragmatic acceptance of conversion obtained through political pressure or military coercion". There were often severe consequences for populations that chose to resist, though in some instances local rulers were able to successfully plead a case for withholding attempts at the forcible Christianization of the populace—both ruler and crusaders cognizant of the risk of armed rebellion (and hence disruption of profitable trade or tribute), were such attempts to proceed.

. Medieval historian Aiden Lilienfeld says "In 1226, however, the
Duke of Mazovia ... granted the Order territory in eastern Prussia in exchange for help in subjugating pagan Baltic peoples". Over the course of the next 200 years, the Order expanded its territory to cover much of the eastern Baltic coast.

The Teutonic Order eventually fell to Poland-Lithuania in 1525. Lilienfeld says "After this, the Order's territory was divided between Poland-Lithuania and the Hohenzollern dynasty of Brandenburg, putting an end to the monastic state and the formal Northern Crusade. All of the Order's most powerful cities–Danzig (Gdansk), Elbing (Elblag), Marienburg (Malbork), and Braunsberg (Braniewo)–now fall within Poland in the 21st century, except for Koenigsburg (Kaliningrad) in Russia."

. Slavic historian Ivo Štefan writes that, Vladimir examined monotheism for himself, and "Around that same time, Vladimir conquered Cherson in the Crimea, where, according to the
Tale of Bygone Years, he was baptized". After returning to Kiev, the same text describes Vladimir as unleashing "a systematic destruction of pagan idols and the construction of Christian churches in their place".

Bohemia, Poland, and Hungary had become part of western Latin Christianity, while the Rus' adopted Christianity from Byzantium, leading them down a different path. A specific form of Rus' Christianity formed quickly.
The Rus' dukes maintained exclusive control of the church which was financially dependent upon them. The prince appointed the clergy to positions in government service; satisfied their material needs; determined who would fill the higher ecclesiastical positions; and directed the synods of bishops in the Kievan metropolitanate. This new Christian religious structure was imposed upon the socio-political and economic fabric of the land by the authority of the state's rulers. According to Andrzej Poppe, Slavic historian, it is fully justifiable to call the Church of Rus' a state church. The Church strengthened the authority of the Prince, and helped to justifiy the expansion of Kievan empire into new territories through missionary activity.
Christian clergy translated religious texts into local vernacular language which introduced literacy to all members of the princely dynasty, including women and the general populace. Monasteries of the twelfth century became key spiritual, intellectual, art, and craft centers. Under Vladimir's son Yaroslav I the Wise (1016–1018, 1019–1054), a building and cultural boom took place. The Church of Rus' gradually developed into an independent political force in the twelfth and thirteenth centuries.

, telling the Pope it was needed to find heretics – specifically Jews pretending to be Christian so they could spy for Moslems who wanted their territory back. In actuality, it served state interests and consolidated power in the monarchy. The Spanish inquisition was originally authorized by the Pope, yet the initial inquisitors proved so severe that the Pope almost immediately opposed it and attempted to shut it down without success. Ferdinand is said to have pressured the Pope, and in October 1483, a papal bull conceded control of the inquisition to the Spanish crown. According to Spanish historian José Casanova, the Spanish inquisition became the first truly national, unified and centralized state institution.

and thus undercut Christianity's identification with colonial rule". According to historical theologian Justo Gonzales, colonialism and missions each sometimes aided and sometimes impeded the other.

Spanish and Portuguese India, Mexico, the Americas, and the Philippines
Portugal practiced extractive colonialism, and was the first to get involved in the pre-existing slave trade. Historian
Kenneth Morgan writes that, "the Portuguese and the Spanish dominated the early phase of transatlantic slavery".
Under Spanish and Portuguese rule, creating a
Christian Commonwealth was the goal of missions. This included a significant role, from the beginning of colonial rule, played by Catholic missionaries.
Early attempts at Christianization in India were not very successful, and those who had been converted were not well instructed. In the church's view, this led them into "errors and misunderstandings" that were often defined as heresy. In December 1560, the state controlled

that replaces indigenous populations with a settler society. Settler colonial states include Canada, the United States, Australia, and South Africa.
Great Britain's colonial expansion was for the most part driven by commercial ambitions and competition with France. Investors saw converting the natives as a secondary concern. Historian of British history and culture, Laura Stevens, writes that British missions were "more talk than walk". From the beginning, the British talked (and wrote) a great deal about converting native populations, but actual efforts were few and feeble. Historian
Jacob Schacter says these missions were universally Protestant, were based on belief in the traditional duty to "teach all nations", the sense of "obligation to extend the benefits of Christianity to heathen lands" (just as Europe itself had been "civilized" centuries before), and a "fervent pity" for those who had never heard the gospel. Schacter adds that "ambivalent benevolence" was at the heart of most British and American attitudes toward Native Americans. The British did not create widespread conversion.

Historian
William Gerald McLoughlin has written that, humanitarians who saw the decline of indigenous people with regret, advocated education and assimilation as the native's only hope for survival. Over time, many missionaries came to respect the virtues of native culture. "After 1828, most missionaries found it difficult to defend the policies of their government" writes McLoughlin.

In 1900 under colonial rule there were just under 9 million Christians in Africa. By 1960, and the end of colonialism there were about 60 million. By 2005, African Christians had increased to 393 million, about half of the continent's total population at that time. Population in Africa has continued to grow with the percentage of Christians remaining at about half in 2022. According to Isichei, "The expansion of Christianity in twentieth-century Africa has been so dramatic that it has been called 'the fourth great age of Christian expansion'."

Simon Kimbangu's movement, the
Kimbanguist church
Kimbanguism () is a Christianity, para-Christian new religious movement professed by the African initiated church Jesus Christ's Church on Earth by his special envoy Simon Kimbangu (, EJCSK) founded by Simon Kimbangu in the Belgian Congo (today ...
, had a radical reputation in its early days in the
Congo, was suppressed for forty years, and is now the most studied of all the African prophet movements. It has become an establishment church in Zaire, is very much involved in modern Zairian life, and with upwards of 3 million members, is now the largest independent church in Africa.
Whether Kimbanguism is a political or a religious movement is resolved by making a distinction between the genuine Kimbanguists and the pseudo-Kimbanguists, also known as the Ngunzists. Of first importance to genuine Kimbanguism is unquestioning acceptance of the intercession of Christ. Measured according to Reformation criteria, the ''Church of Jesus Christ of this Earth by the Prophet Simon Kimbangu'' (EJCSK) is a Christian religion. However, as
James W. Fernandez says, it is a mistake to identify Christianity only with its European version.
Jules Rosette shows how ritual symbolization is the training ground, the interface, for the translation of the African into the Christian, "how ritual vocabulary translates tradition into new practices". Christianity, she suggests, provides the grammar and syntax, as it were, and traditional customs the lexicon that is formulated by Christianity into a new religious argument.
Tanzania
In Tanzania, a child is not a full member of society until they reach adulthood. Adulthood begins at puberty, but a man fully enters adult society by marrying, a woman by giving birth, and the transition from childhood to adulthood is marked by initiation rites. For the Maasai, this includes circumcision of both boys and girls.
Anne Marie Stoner-Eby writes, "The Christianization of initiation rites in the Anglican Diocese of Maasai in what is now southeastern Tanzania is arguably the most famous instance of 'adaptation' in African mission Christianity."
It has long been assumed that
Vincent Lucas, Bishop of Maasai (1926–1944), initiated the Christianizing of the initiation rites in an effort to adapt, and not destroy African cultural life, publishing what became a famous essay on 'The Christian Approach to Non-Christian Customs'.
Initiation was one of a chief's most important and prestigious responsibilities, but long before 'adaptation' became a missionary watchword, Maasai clergy had taken advantage of a crucial increase in their numbers to place ''jando la kikristo'' (Christian initiation) in place of ''unyago wa lupanda'' (Lupanda initiation in ancestor worship) by 1913.

moving former colonies toward independence. Shifting beliefs about Christianity's role in empire began in France in the 1930s and 40s. Christians were rethinking the relationship between religion and politics. From the 1960s onward, this new understanding of theology combined with Christian activism, was instrumental in motivating indigenous people, such as the Algerians, to work toward and fight for independence from foreign governments. This in turn, influenced global trends. In some colonial societies, Christian missionaries played a transformative role in the development of decolonization and post-colonial Christianity, where in others, the nature of the Christian missionary presence shaped the pattern of decolonization as one of violence and opposition.
In the post-colonial world, it has become necessary for Christianization to break free of its colonial moorings, says Sanneh. Mark Boyle writes that:
Christianity's historical alignment with the Western project and he overlappinghistories of colonialism and imperialism raises questions about its capacity to serve as a progressive force in global affairs today. Placing Christianity under postcolonial scrutiny, ... Christianity offers a variety of complex, contradictory, and competing approaches to peace building that variously defend the hegemonic ambitions of the West on the one hand, and support critical practices that usurp and decenter the sovereign supremacy assumed by the West on the other.
Global Christianization
Dana L. Robert has written that one third of the world's population is now Christian in a huge variety of forms. The geographic range, cultural diversity and organizational variety of these many types of Christians includes traditional Catholics in Brazil, Apostles in Zimbabwe, Coptic Christians still surviving in Egypt, new Pentecostals in Ghana, established Lutherans in Germany, and secret House church believers in China.
In the early twenty-first century, Christianity has been declining in the West and growing in former colonial lands. Sanneh says Christianity has become the most diverse, pluralist, fastest growing religion in the world.

has transitioned from a state of disintegration in the
late Imperial era (960–1895) to one of modern entrepreneurial cosmopolitanism with the aid of Christianization. Indigenization happened quickly and Christianization has survived through family lineage networks, which function like a single corporate unit, and native congregations.
Christianity grew as a grassroots movement in rural areas first, through self-propagation and native agency. This led to an overlap of religious, kinship and territorial identities, so that when the socio-political order shattered, the church was able to step in. Lee sees this as revealing "the importance of the church as a major building block and a viable civic institution in the midst of widespread chaos and unrest".
Lee writes that hostility toward Christianity as expressed in the
Anti-Christian Movement (1925–1926) and in the anti-religious Maoist Era (1949–1976), "the impact of regime change, encounters with secular state-building, the church's involvement in transforming local religious and socio-economic landscapes, and the importance of religious agency", are all key factors in Chinese Christianity. There exists a multiplicity of Chinese Christian experiences and religiosity, and they all tend to reject the view that Christianity is incompatible with modern Chinese culture.
