Christianity in Asia
Christianity in Asia has its roots in the very inception of Christianity, which originated from the life and teachings of Jesus in 1st-century Roman Judea. Christianity then spread through the missionary work of his apostles, first in the Levant and taking roots in the major cities such as Jerusalem and Antioch. According to tradition, further eastward expansion occurred via the preaching of Thomas the Apostle, who established Christianity in the Parthian Empire and India. The very First Ecumenical Council was held in the city of Nicaea in Asia Minor. The first nations to adopt Christianity as a state religion were Armenia in 301 and Georgia in 327. By the 4th century, Christianity became the dominant religion in all Asian provinces of the Eastern Roman Empire.
After the First Council of Ephesus in 431 and the Nestorian Schism, the Nestorian Christianity developed. Nestorians began converting Mongols around the 7th century, and Nestorian Christianity was probably introduced into China during the Tang Dynasty. Mongols tended to be tolerant of multiple religions, with several Mongol tribes being primarily Christian, and under the leadership of Genghis Khan's grandson, the great khan Möngke, Christianity was a small religious influence of the Mongol Empire in the 13th century.
The Fourth Ecumenical Council was held in Asian city of Chalcedon. Christological controversies and disputes that surrounded the Council and its aftermath gradually resulted in division between pro-Chalcedonian and anti-Chalcedonian Christianity.
Father Jordanus Catalani, a French Dominican missionary, followed in 1321–22. He reported to Rome, apparently from somewhere on the west coast of India, that he had given Christian burial to four martyred monks. Jordanus is known for his 1329 "Mirabilia" describing the marvels of the East: he furnished the best account of Indian regions and the Christians, the products, climate, manners, customs, fauna and flori given by any European in the Middle Ages - superior even to Marco Polo's.
The Roman Catholic Diocese of Quilon or Kollam is the first Catholic diocese in Asia, India in the state of Kerala. First erected on 9 August 1329 and re-erected on 1 September 1886. In 1329 Pope John XXII erected Quilon as the first Diocese in the whole of Indies as suffragan to the Archdiocese of Sultany in Persia through the decree "Romanus Pontifix" dated 9 August 1329. By a separate Bull "Venerabili Fratri Jordano", the same Pope, on 21 August 1329 appointed the French Dominican friar Jordanus Catalani de Severac as the first Bishop of Quilon.. Around that same time, there was some effort to reunite Eastern and Western Christianity. There were also numerous missionary efforts from Europe to Asia, primarily by Franciscan, Dominican, or Jesuit missionaries. In the 16th century, Spain began to convert Filipinos. In the 18th century, Catholicism developed more or less independently in Korea.
At present, Christianity continues to be the majority religion in the Philippines, East Timor, Armenia, Georgia, Cyprus and Russia. It has significant minority populations in South Korea, Taiwan, China, India, Pakistan, Iran, Indonesia, Vietnam, Singapore, Hong Kong, Japan, Malaysia, Kazakhstan, Kyrgyzstan, Israel, Palestine, Lebanon, Syria, Iraq, Jordan, and several other countries in Asia with a total Christian population of more than 295 million.
Early spread in Asia
Western Asia
Levant
Christianity spread through the Levant from the 1st century AD. One of the key centers of Christianity became the city of Antioch, previous capital of the Hellenistic Seleucid Empire, located in today what is modern Turkey. Antioch was evangelized perhaps by Peter the Apostle, according to the tradition upon which the Antiochene patriarchate still rests its claim for primacy, and certainly by Barnabas and Paul. Its converts were the first to be called Christians. They multiplied rapidly, and by the time of Theodosius were reckoned by Chrysostom, Archbishop of Constantinople, at about 100,000 people. Between 252 and 300, ten assemblies of the church were held at Antioch and it became the seat of one of the original five patriarchates, along with Jerusalem, Alexandria, Constantinople, and Rome.Caucasus
and Georgia were the first nations to adopt Christianity as a state religion, in 301 and 326 respectively.Christianity had been preached in Armenia by two of Jesus' twelve apostles — Thaddaeus and Bartholomew — between 40-60 AD. Because of these two founding apostles, the official name of the Armenian Church is Armenian Apostolic Church, and it is considered to be the world's oldest national church. The Church of Caucasian Albania was established in 313, after Caucasian Albania became a Christian state.
In Georgia, Christianity was first preached by the apostles Simon and Andrew in the first century. It became the state religion of Kartli, Iberia in 326. The conversion of Georgia to Christianity is credited to the efforts of Saint Nino of Cappadocia.
Parthian Empire
Christianity further spread eastward under the Parthian Empire, which displayed a high tolerance of religious matters. According to tradition, Christian proselytism in Central Asia, starting with Mesopotamia and the Iranian plateau, was put under the responsibility of Saint Thomas the Apostle, and started in the first century AD. Saint Thomas is also credited with the establishment of Christianity in India. The Christians of Mesopotamia and Iran were organized under several bishops, and were present at the First Council of Nicaea in 325 AD.Expansion to Central Asia
The spread of Christianity in Central Asia seems to have been facilitated by the great diffusion of Greek in the region, as well as Aramaic, the language of Jesus Christ. The spread of the Jews in Asia since the deportation from Babylon and the capture of Jerusalem by Titus also seems to have been a contributing factor.The earliest known references to Christian communities in Central Asia is from a writing by Bar Daisan around 196 AD: "Nor do our sisters among the Gilanians and Bactrians have any intercourse with strangers".
The Sasanians also proved rather tolerant of the Christian faith until the persecution by the Zoroastrian priest Kartir under Bahram II. Further persecutions seem to have taken place under Shapur II and Yazdegerd II, with events in 338 having brought significant damage to the faith.
India (1st century AD)
According to Eusebius' record, the apostles Thomas and Bartholomew were assigned to Parthia and India. By the time of the establishment of the Second Persian Empire, there were bishops of the Church of the East in northwest India, Afghanistan and Baluchistan, with laymen and clergy alike engaging in missionary activity.An early third-century Syriac work known as the Acts of Thomas connects the apostle's Indian ministry with two kings, one in the north and the other in the south. According to the Acts, Thomas was at first reluctant to accept this mission, but the Lord appeared to him in a night vision and compelled him to accompany an Indian merchant, Abbanes, to his native place in northwest India. There, Thomas found himself in the service of the Indo-Parthian King, Gondophares. The Apostle's ministry resulted in many conversions throughout the kingdom, including the king and his brother.
Thomas thereafter went south to Kerala and baptized the natives, whose descendants form the Saint Thomas Christians or the Syrian Malabar Nasranis.
Piecing together the various traditions, the story suggests that Thomas left northwest India when invasion threatened, and traveled by vessel to the Malabar Coast along the southwestern coast of the Indian continent, possibly visiting southeast Arabia and Socotra en route, and landing at the former flourishing port of Muziris on an island near Cochin in 52. From there he preached the gospel throughout the Malabar Coast. The various Churches he founded were located mainly on the Periyar River and its tributaries and along the coast. He preached to all classes of people and had about 170 converts, including members of the four principal castes. Later, stone crosses were erected at the places where churches were founded, and they became pilgrimage centres. In accordance with apostolic custom, Thomas ordained teachers and leaders or elders, who were reported to be the earliest ministry of the Malabar church.
Thomas next proceeded overland to the Coromandel Coast in southeastern India, and ministered in what is now the Madras area, where a local King and many people were converted. One tradition related that he went from there to China via Malacca in Malaysia, and after spending some time there, returned to the Madras area. Apparently his renewed ministry outraged the Brahmins, who were fearful lest Christianity undermine their social caste system. So according to the Syriac version of the Acts of Thomas, Mazdai, the local king at Mylapore, after questioning the Apostle condemned him to death about the year AD 72. Anxious to avoid popular excitement, the King ordered Thomas conducted to a nearby mountain, where, after being allowed to pray, he was then stoned and stabbed to death with a lance wielded by an angry Brahmin.
Expansion of Nestorian Christianity (431-1360 AD)
In 410 the Sassanid emperor summoned the Persian church leaders to the Synod of Seleucia. His purpose was to make the Catholicos of Seleucia-Ctesiphon the minority leader of the Christians in the Empire, and personally responsible for their good conduct throughout the Persian empire. The synod accepted the emperor's wish.In 424 the bishops of Persia met in council under the leadership of Catholicos Dadiso and determined that there would be no reference of their disciplinary or theological problems to any other power, especially not to any church council in the Roman Empire. The formal separation from the See of Antioch and the western Syrian Church under the Roman Emperors, occurred at this synod in 424.
Nestorianism
The eastern development of Christianity continued to separate from the west, pushed along by such events as 431's Council of Ephesus, in which the Syrian bishop Nestorius, Patriarch of Constantinople since 428, was accused of heresy for preaching his brand of Christianity, labelled Nestorianism after him. He and his followers were banished from the Byzantine Empire, and other religious and political institutions gave him sanctuary. Eastern Christianity seceded to form what is sometimes called the Church of the East, or Syro-Oriental Church, though some historians refer to it with the catchall term Nestorian Church, even though many Eastern Christians were not following the doctrine preached by Nestorius.Expansion to Sogdiana and eastern Central Asia
Proselytism, combined with sporadic Sassanian persecutions and the exiling of Christian communities in their own area, caused the spread of Christianity to the east.The Edict of Milan in 313, granted Christianity toleration by the Roman Empire. After the Emperor Constantine's conversion to Christianity, the indigenous Christians of Persia were considered a political threat to the Sassanians. They exiled Christian communities to the east, such as a community of Orthodox Melchites who were installed in Romagyri near Tashkent, or a community of Jacobites, who were sent to Yarkand in the Xinjiang at the doorstep of China. The Hephthalites are known to have been open somewhat to Christianity since 498, and they requested the Nestorian Catholicos to establish a diocesan bishop in their lands in 549.
By 650, there were 20 Nestorian dioceses east of the Oxus river. The development of Islam in the late 7th century further cut off Asian Christianity from the western Christians, but eastern expansion of the faith continued nonetheless. Relations with Islam were good enough for the Catholicos to leave Seleucia-Ctesiphon to set up his seat in Baghdad upon the establishment of the Abbassids in 750.
From the 7th century onward, the nomadic Turks of Central Asia started to convert to Nestorian Christianity. Mass conversions are recorded in 781−2 and later in 1007, when 200,000 Turks and Mongols reportedly became Christians. The Turkish Kipchaks are also known to have converted to Christianity at the suggestion of the Georgians as they allied in their conflicts against the Muslims. A great number were baptized at the request of the Georgian king David II. From 1120, there was a Kipchak national Christian church and an influential clergy.
Early Christianity in China
Christianity may have existed earlier in China, but the first documented introduction was during the Tang Dynasty A Christian mission under the leadership of the priest Alopen was known to have arrived in 635, where he and his followers received an Imperial Edict allowing for the establishment of a church. In China, the religion was known as Dàqín Jǐngjiào, or the Luminous Religion of the Romans. 大秦 Dàqín designates Rome and the Near East, though from the Western view, Nestorian Christianity was considered heretical by the Latin Christians.Opposition arose to the Christians in 698-699 from the Buddhists, and then from the Daoists in 713, but Christianity continued to thrive, and in 781, a stone stele was erected at the Tang capital of Chang-an, which recorded 150 years of Emperor-supported Christian history in China. The text of the stele describes flourishing communities of Christians throughout China, but beyond this and few other fragmentary records, relatively little is known of their history. In later years, other emperors were not as religiously tolerant. In 845, the Chinese authorities implemented an interdiction of foreign cults, and Christianity diminished in China until the time of the Mongol Empire in the 13th century.
Christianity among the Mongols
Overall, Mongols were highly tolerant of most religions, and typically sponsored several at the same time. They had been proselytized by Nestorian Christians since about the 7th century, and several Mongol tribes, such as the Kerait, Naimans, Merkit, and to a large extent the Kara Khitan, were also Christian.The founder of the Mongol Empire, Genghis Khan was a shamanist, but showed great tolerance to other religions. His sons were married to Christian princesses of the Kerait clan, such as Sorghaghtani Beki and Doquz Khatan, a remarkable Kerait noblewoman, the granddaughter of Toghrul Khan and a passionate Christian who held considerable influence at the court of the Khan. She made no secret of her dislike of Islam and her eagerness to help Christians of every sect.
Under the rule of Genghis's grandson Möngke Khan, son of Sorghaghtani, the main religious influence was that of the Christians, to whom Möngke showed especial favour in memory of his mother.
East–West rapprochement
Following the East–West Schism of 1054, various efforts, over several centuries, were made at reuniting eastern and western Christianity, with the objective of putting both under the rule of the Pope.Armenian Church
In 1198, a Union was proclaimed between Rome and the Armenian Church by the Armenian catholicos of Sis, Grigor VI Apirat. This was not followed in deeds however, as the local clergy and populace was strongly opposed to such a union. Again in 1441, the Armenian Catholicos of Sis Grigor IX Musabekiants proclaimed the union of the Armenian and Latin churches at the Council of Florence, but this was countered by an Armenian schism under Kirakos I Virapetsi, which installed the Catholicos see at Edjmiatzin, and marginalized Sis.Numerous Roman Catholic missions were also sent to Cilician Armenia to help with rapprochement. The Franciscans were put in charge of these missions. William of Rubruck visited Cilicia in 1254, and John of Monte Corvino in 1288. The Armenian king Hethoum II would himself become a Franciscan friar upon his multiple abdications. Another such monk was the historian Nerses Balients, who was a member of the "Unitarian" movement advocating unification with the Latin Church.
Byzantine Church
Various efforts were also made by the Byzantine Church to unite with Rome. In 1272, John of Montecorvino was commissioned by the Byzantine emperor Michael VIII Palaiologos to communicate with Pope Gregory X, to negotiate for the reunion of the Orthodox and Catholic Churches. The objective was to drive a wedge between the pope and supporters of the Latin Empire, who had views on reconquering Constantinople. A tenuous union between the Greek and Latin churches was signed at the Second Council of Lyons in 1274. Michael VIII's concession was met with determined opposition at home, and prisons filled with many opponents to the union. At the same time the unionist controversy helped drive Byzantium's Orthodox neighbors Serbia and Bulgaria into the camp of Michael VIII's opponents. For a while the diplomatic intent of the union worked out in the West, but in the end Pope Martin IV, an ally of Charles of Anjou, excommunicated Michael VIII.Catholic missions to the Mongols and China
Contacts between the Mongols and the West occurred in the 13th century, as the Mongol Empire expanded towards Europe and Palestine, coinciding with the latter part of the Crusades. Initial contacts showed that the Mongols had the impression that the Pope was the leader of the Europeans, and sent him messages insisting that he submit Europe to Mongol authority. In return, the Mongols stated that after they conquered Jerusalem, they would return it to the Crusaders. The various popes, for their part, seemed to be unaware that Christianity already existed in the East, and tended to respond with messages insisting that the Mongols convert to Christianity and accept baptism. Later communications between the Mongols and Europe saw attempts to form a Franco-Mongol alliance against the Muslims.In 1253, King Louis IX sent the Franciscan William of Rubruck to the Mongol capital of Karakorum to convert the Tartars. William visited the court of the great khan Möngke in 1254, and observed representatives of several religions there. He engaged in a famous debate set up by Möngke, with representatives of each religion debating which was best. He left in August 1254, bearing Möngke's reply to King Louis.
to Pope Gregory X in 1271.
In 1268, Marco Polo's father and uncle returned from China with an invitation from Kublai Khan to the pope, imploring him that a hundred teachers of science and religion be sent to reinforce the Christianity already present in Kublai's empire. However, this came to naught due to the hostility of influential Nestorian Christians within the largely Mongol court. Kublai did request Western assistance to secure Mongol rule over the Chinese Yuan Dynasty. In 1289, Pope Nicholas IV sent the Franciscan John of Monte Corvino to China by way of India. Although Kublai had already died by the time John arrived in 1294, the court at Khanbaliq received him graciously and encouraged him to settle there. John was China's first Roman Catholic missionary, and he was significantly successful. He laboured largely in the Mongol tongue, translated the New Testament and Psalms, built a central church, and within a few years could report 6,000 baptized converts. He also established a lay training school of 150 students. Other priests joined him, John was consecrated a bishop, and centers were established in the coastal provinces of Kiangsu, Chekiang and Fukien. Under John's influence, many Mongols, such as those of the Ongut tribe, changed allegiance from the Eastern Nestorian Church, to Western Roman Catholicism.
Following the death of Monte Corvino, an embassy to the French Pope Benedict XII in Avignon was sent by Toghun Temür in 1336, requesting a new spiritual guide. The pope replied by appointing four ecclesiastics as his legates to the khan's court. In 1338, a total of 50 ecclesiastics were sent by the Pope to Peking, such as John of Marignolli, who arrived in Khanbaliq in 1342, and stayed until 1347, then returning to Avignon in 1353.
However, the Mongol-established Yuan Dynasty in China was in decline, and in 1368 was overthrown by the Ming Dynasty founded by the native Chinese. The last Catholic bishop of Quanzhou, Giacomo da Firenze, was killed by the Chinese in 1362. By 1369 all Christians, whether Roman Catholic or Nestorian, were expelled.
European voyages of exploration
The European voyages of exploration in the 16th century would create new opportunities for Christian proselytism.Christianity in the Philippines
's arrival in Cebu represents the first attempt by Spain to convert natives to Christianity. According to a description of events, Magellan met with Raja Humabon of Cebu, who had an ill grandson whom the explorer, or one of his men, was able to help cure. Out of gratitude, Humabon and his chief consort allowed themselves to be christened "Carlos" and "Juana", with some 800 of his subjects also being baptised. Later, Lapu-Lapu, the monarch of neighbouring Mactan Island had his men killed Magellan and routed the ill-fated Spanish expedition.In 1564, Luís de Velasco, the Viceroy of New Spain, sent the Basque explorer Miguel López de Legazpi to the Philippines. Legazpi's expedition, which included the Augustinian friar and circumnavigator Andrés de Urdaneta, erected what is now Cebu City under the patronage of the Holy Child, and later conquered the Kingdom of Maynila in 1571 and the neighbouring Kingdom of Tondo in 1589. The colonisers then proceeded to proselytise as they explored and subjugated the remaining parts of what is now the Philippines until 1898, with the exception of parts of Mindanao, which had been Muslim since at latest the 10th century CE, and the Cordilleras, where numerous mountain tribes maintained their ancient beliefs as they resisted Western colonisation until the arrival of the United States in the early 20th century.
Christianity in Indonesia
A 12th-century Christian Egyptian record of churches suggest that a church was established in Barus, on the west coast of North Sumatra, a trading post known to have been frequented by Indian traders, and therefore linked to the Indian Saint Thomas Christians. No record nor trace of such a community remains, and the first significant evidence of Christian activity came with the arrival of Portuguese traders in the 16th century.The Portuguese arrived in the Malacca Sultanate in 1509 seeking access to its wealth. Although initially well-received, the capture of Goa as well as other Muslim–Christian conflicts convinced the Malaccan Muslims that the Portuguese Christians would be a hostile presence. The resulting capture of Malacca is believed to have enhanced a sense of Muslim solidarity against the Christian Portuguese, and ongoing resistance against the Portuguese came from Muslim Aceh as well as from the Ottoman Empire. Although the Portuguese built some churches in Portuguese Malacca itself, their evangelical influence in neighbouring territories was perhaps more negative than positive in promulgating Christianity.
The first missionaries were sent by Stamford Raffles in 1824, at which time Sumatra was under temporary British rule. They observed that the Batak seemed receptive to new religious thought, and were likely to fall to the first mission, either Islamic or Christian, to attempt conversion.
A second mission that in 1834 of the American Board of Commissioners for Foreign Missions met with a brutal end when its two missionaries were killed by Batak resistant to outside interference in their traditional adat.
The first Christian community in North Sumatra was established in Sipirok, a community of Angkola people. Three missionaries from an independent church in Ermelo, Netherlands arrived in 1857, and on 7 October 1861 one of the Ermelo missionaries united with the Rhenish Missionary Society, which had been recently expelled from Kalimantan as a result of the Banjarmasin War.
The mission was immensely successful, being well supported financially from Germany, and adopted effective evangelistic strategies led by Ludwig Ingwer Nommensen, who spent most of his life from 1862 until his death in 1918 in North Sumatra, successfully converting many among the Simalungun and Batak Toba as well as a minority of Angkola.
Jesuits in China
The missionary efforts and other work of the Society of Jesus, or Jesuits, between the 16th and 17th century played a significant role in continuing the transmission of knowledge, science, and culture between China and the West, and affected Christian culture in Chinese society today. Members of the Jesuit delegation to China were perhaps the most influential of the different Christian missionaries in that country between the earliest period of the religion up until the 19th century, when significant numbers of Catholic and Protestant missions developed. Prominent Jesuit missionaries included the Navarrese St. Francis Xavier, and the Italian Matteo Ricci. At the time of their peak influence, members of the Jesuit delegation were considered some of the emperor's most valued and trusted advisors, holding numerous prestigious posts in the imperial government. However, between the 18th and mid-19th century, nearly all Western missionaries in China were forced to conduct their teaching and other activities covertly.Independently formed Catholic movements (Korea)
The history of Catholicism in Korea began in 1784 when Yi Sung-hun was baptized while in China under the Christian name of Peter. He later returned home with various religious texts and baptized many of his fellow countrymen. The Church in Korea survived without any formal missionary priests until clergy from France arrived in 1836 for the ministry.During the 19th century, the Catholic Church suffered persecution by the government of the Joseon Dynasty, chiefly for the religion's refusal to carry out ancestral worship, which it perceived to be a form of idolatry, but which the State prescribed as a cornerstone of culture. A century-long persecution produced thousands of martyrs - 103 of whom were canonized by Pope John Paul II in May 1984, including the first Korean priest, St. Andrew Dae-gun Kim, who was ordained in 1845 and martyred in 1846. Despite the persecution though, the Church in Korea expanded. The Apostolic Vicariate of Korea was formed in 1831, and after the expansion of Church structure for next century, the current structure of three Metropolitan Provinces each with an Archdiocese and several suffragan Dioceses was established in 1962.
Currently Deokwon in North Korea is the See of the only territorial abbey outside Europe. The abbey was vacant for more than 50 years until Fr. Francis Ri was appointed as abbot in 2005. The abbey was never united with or changed into a diocese presumably due to the lack of effective church activity in the area since the division of Korea at the end of World War II.
Christianity in Asia today
Today, Christianity is the predominant faith in six Asian countries, the Philippines, East Timor, Cyprus, Russia, Armenia and Georgia. The rise of Islamic extremism has, in some Muslim dominant areas, led to persecution and, in the worse cases, torture and death. In many Muslim countries, however, including both conservative and liberal, Christians continue to enjoy freedom of worship, despite limits on their ability to spread their faith.A 2015 study estimates 6,968,500 Christian believers from a Muslim background in Asia, while about 483,500 Christian believers from a Muslim background in the Middle East, most of them belonging to some form of Protestantism.
