Religion in South Korea is characterized by the fact that a majority of South Koreans (56.1%) as of the 2015 national census) have no formal affiliation with a religion. Among those who are members of a religious organisation, Protestantism represents (19.7%) of the total population, Buddhism (15.5%), and Catholicism (7.9%). A small percentage of South Koreans (0.8% in total) are members of other religions, including Won Buddhism, Confucianism, Cheondoism, Daesun Jinrihoe, Daejongism, Jeungsanism, and Orthodox Christianity.
Buddhism was influential in ancient times and Christianity had influenced large segments of the population in the 18th and 19th century, yet they grew rapidly in membership only by the mid-20th century, as part of the profound transformations that South Korean society went through in the past century.But they have shown some decline from the year 2000 onwards. Native shamanic religions (i.e. Sindo) remain popular and could represent a large part of the unaffiliated. Indeed, according to a 2012 survey, only 15% of the population declared themselves to be not religious in the sense of "atheism". According to the 2015 census, the proportion of the unaffiliated is higher among the youth, about 65% among the 20-years old.
Korea entered the 20th century with an already ingrained Christian presence and a vast majority of the population practicing native religion (Sindo). The latter never gained the high status of a national religious culture comparable to Chinese folk religion and Japan's Shinto; this weakness of Korean Sindo was among the reasons that left a free hand to an early and thorough rooting of Christianity. The population also took part in Confucianising rites and held private ancestor worship. Organised religions and philosophies belonged to the ruling elites, and the long patronage exerted by the Chinese empire led these elites to embrace a particularly strict Confucianism (i.e. Korean Confucianism). Korean Buddhism, despite an erstwhile rich tradition, at the dawn of the 20th century was virtually extinct as a religious institution, after 500 years of suppression under the Joseon kingdom. Christianity had antecedents in the Korean peninsula as early as the 18th century, when the philosophical school of Seohak supported the religion. With the fall of the Joseon in the last decades of the 19th century, Koreans largely embraced Christianity, since the monarchy itself and the intellectuals looked to Western models to modernise the country and endorsed the work of Catholic and Protestant missionaries. During Japanese colonisation in the first half of the 20th century, the identification of Christianity with Korean nationalism was further strengthened, as the Japanese tried to merge native Sindo with their State Shinto.
With the division of Korea into two states after 1945, the communist north and the anti-communist south, the majority of the Korean Christian population that had been until then in the northern half of the peninsula, fled to South Korea. It has been estimated that Christians who migrated to the south were more than one million. Throughout the second half of the 20th century, the South Korean state enacted measures to further marginalise indigenous Sindo, at the same time strengthening Christianity and a revival of Buddhism. According to scholars, South Korean censuses do not count believers in indigenous Sindo and underestimate the number of adherents of Sindo sects. Otherwise, statistics compiled by the ARDA estimate that as of 2010, 14.7% of South Koreans practice ethnic religion, 14.2% adhere to new movements, and 10.9% practice Confucianism.
According to some observers, the sharp decline of some religions (Catholicism and Buddhism) recorded between the censuses of 2005 and 2015 is due to the change in survey methodology between the two censuses. While the 2005 census was an analysis of the entire population ("whole survey") through traditional data sheets compiled by every family, the 2015 census was largely conducted through the internet and was limited to a sample of about 20% of the South Korean population. It has been argued that the 2015 census penalised the rural population, which is more Buddhist and Catholic and less familiar with the internet, while advantaging the Protestant population, which is more urban and has easier access to the internet. Both the Buddhist and the Catholic communities criticised the 2015 census' results.

Prior to the introduction of Buddhism, all Koreans believed in their indigenous religion socially guided by mu (shamans). Buddhism was introduced from the Chinese Former Qin state in 372 to the northern Korean state of Goguryeo and developed into distinctive Korean forms. At that time, the peninsula was divided into three kingdoms: the aforementioned Goguryeo in the north, Baekje in the southwest, and Silla in the southeast. Buddhism reached Silla only in the 5th century, but it was made the state religion only in that kingdom in the year 552. Buddhism became much more popular in Silla and even in Baekje (both areas now part of modern South Korea), while in Goguryeo the Korean indigenous religion remained dominant. In the following unified state of Goryeo (918-1392) Buddhism flourished, and even became a political force.
The Joseon kingdom (1392-1910), adopted an especially strict version of Neo-Confucianism (i.e. Korean Confucianism) and suppressed and marginalised Korean Buddhism and Korean shamanism. Buddhist monasteries were destroyed, and their number dropped from several hundreds to a mere thirty-six; Buddhism was eradicated from the life of towns as monks and nuns were prohibited from entering them and were marginalised to the mountains. These restrictions lasted until the 19th century.
In the late 19th century, the Joseon state was politically and culturally collapsing. The intelligentsia was looking for solutions to invigorate and transform the nation. It was in this critical period that they came into contact with Western Christian missionaries who offered a solution to the plight of Koreans. Christian communities already existed in Joseon since the 17th century, however it was only by the 1880s that the government allowed a large number of Western missionaries to enter the country. Christian missionaries set up schools, hospitals and publishing agencies. The royal family supported Christianity.
During the absorption of Korea into the Japanese Empire (1910-1945) the already formed link of Christianity with Korean nationalism was strengthened, as the Japanese tried to impose State Shinto, co-opting within it native Korean Sindo, and Christians refused to take part in Shinto rituals. At the same time, numerous religious movements that since the 19th century had been trying to reform the Korean indigenous religion, notably Cheondoism, flourished.
With the division of Korea into two states in 1945, the communist north and the anti-communist south, the majority of the Korean Christian population that had been until then in the northern half of the peninsula, fled to South Korea. Christians who resettled in the south were more than one million. Cheondoists, who were concentrated in the north like Christians, remained there after the partition, and South Korea now has no more than few thousands Cheondoists.
The so-called "movement to defeat the worship of gods" promoted by governments of South Korea in the 1970s and 1980s, prohibited indigenous cults and wiped out nearly all traditional shrines (sadang ) of the Confucian kinship religion. This was particularly tough under the rule of Park Chung-hee (a Buddhist).
This measure, combined with the rapid social changes of the same period, favoured a rapid revival of Korean Buddhism and growth of Christian churches in a trend to register as members of organised religions. The number of Buddhist temples rose from 2,306 in 1962 to 11,561 in 1997, Protestant churches rose from 6,785 in 1962 to 58,046 in 1997, the Catholic Church had 313 churches in 1965 and 1,366 in 2005, Won Buddhism had 131 temples in 1969 and 418 in 1997. Similarly, Daesun Jinrihoe's temples have grown from 700 in 1983 to 1,600 in 1994. Statistics from censuses show that the proportion of the South Korean population self-identifying as Buddhist has grown from 2.6% in 1962 to 22.8% in 2005, while the proportion of Christians has grown from 5% in 1962 to 29.2% in 2005. However, both religions have shown a decline between the years 2005 and 2015, with Buddhism sharply declining in influence to 15.5% of the population, and a less significant decline of Christianity to 27.6%.
Since the 1980s and the 1990s there have been acts of hostility committed by Protestants against Buddhists and followers of traditional religions in South Korea. This include the arson of temples, the beheading of statues of Buddha and bodhisattvas, and red Christian crosses painted on either statues or other Buddhist and other religions' properties. Some of these acts have even been promoted by churches' pastors.
In 2018, a mass protest broke out in support of freedom of religion and against the government's inaction on widespread programs of violent forced conversion carried out by Christian churches under the guide of the Christian Council of Korea (CCK), just after a woman named Ji-In Gu, one among approximately a thousand victims of the churches, was kidnapped and killed while being forced to convert. Before being killed, Ji-In Gu dedicated herself in exposing the conversion treatments, and for such reason she had become a target of the Christian churches.
Christianity ( Geurisdogyo or Gidoggyo) in South Korea is predominantly Catholic ( Cheonjugyo, "religion of the Lord of Heaven", or Gatollik gyohoe) and Protestant ( Yeolgyo, "religion of split", or Gaesingyo, "religion of the innovators"), respectively with 3.8 million and 9.6 million members as of the 2015 census. There are also small communities of Eastern Orthodoxy ( Jeonggyohoe, "authentic church") under the jurisdiction of the Ecumenical Patriarchate of Constantinople, and Coptic Orthodoxy ( Kopteu Jeonggyohoe).
Foreign Roman Catholic missionaries did not arrive in Korea until 1794, a decade after the return of Yi Sung-hun, a diplomat who was the first baptised Korean in Beijing. He established a grass roots lay Catholic movement in Korea. However, the writings of the Jesuit missionary Matteo Ricci, who was resident at the imperial court in Beijing, had been already brought to Korea from China in the 17th century. Scholars of the Silhak ("Practical Learning") were attracted to Catholic doctrines, and this was a key factor for the spread of the Catholic faith in the 1790s. The penetration of Western ideas and Christianity in Korea became known as Seohak ("Western Learning"). A study of 1801 found that more than half of the families that had converted to Catholicism were linked to the Seohak school. Largely because converts refused to perform Confucian ancestral rituals, the Joseon government prohibited Christian proselytising. Some Catholics were executed during the early 19th century, but the restrictive law was not strictly enforced.
Protestant missionaries entered Korea during the 1880s and, along with Catholic priests, converted a remarkable number of Koreans, this time with the support of the royal government which winked at Westernising forces in a period of deep internal crisis (due to the waning of centuries-long patronage from a then-weakened China). The lack of a national religious system compared to those of China and that of Japan (Korean Sindo never developed to a high status of institutional and civic religion) gave a free hand to Christian churches.Methodist and Presbyterian missionaries were especially successful. They established schools, universities, hospitals, and orphanages and played a significant role in the modernisation of the country.
Many Koreans began to migrate to Russia in the 1860s and many of them subsequently converted to Eastern Orthodox Church. Orthodox missionaries entered Korea from Russia in 1900. In 1903, the first Orthodox Church in Korea was established. However, the Russo-Japanese war in 1904 and the Russian Revolution in 1918 interrupted the activities of the mission.
During the Japanese colonial occupation, Christians were in the front ranks of the struggle for independence. Factors contributing to the growth of Catholicism and Protestantism included the decayed state of Korean Buddhism, the support of the intellectual elite, and the encouragement of self-support and self-government among members of the Korean church, and finally the identification of Christianity with Korean nationalism.
A large number of Christians lived in the northern part of the peninsula (it was part of the so-called "Manchurian revival") where Confucian influence was not as strong as in the south. Before 1948 Pyongyang was an important Christian centre: one-sixth of its population of about 300,000 people were converts. Following the establishment of the communist regime in the north, an estimated more than one million Korean Christians resettled to South Korea to escape persecution by North Korea's anti-Christian policies. And at that time, the small Orthodox community of Korea received support from South Koreans ally Greece. So, Korean Orthodox faithful requested to come under the spiritual care of the Ecumenical Patriarchate of Constantinople in 1955 and the Ecumenical Patriarchate took Korean Orthodox Church under its protection in 1956.
Christianity grew significantly in the 1970s and 1980s. In the 1990s it continued to grow, but at a slower rate, and since the 2000s it has shown some decline. Christianity is especially dominant in the west of the country including Seoul, Incheon, and the regions of Gyeonggi and Honam. The Christian faith in South Korea is dominated by four denominations: Catholicism, Presbyterianism ( pronounced Jangnogyo), Methodism ( pronounced Gamnigyo) and Baptists ( pronounced Chimnyegyo). The Yoido Full Gospel Church is the largest Pentecostal church in the country. Some non-denominational churches also exist. Korean Catholics still observe jesa (ancestral rites); the Korean tradition is very different from the institutional religious ancestral worship that is found in China and Japan and can be easily integrated as ancillary to Christianity. Orthodox and Protestants, by contrast, have completely abandoned the practice.
The peace churches have not gained a strong foothold on the peninsula. Quaker thought briefly attracted a national following in the late 20th century, thanks to the leadership of Ham Seok-heon. However, after Ham's death, interest in Quakerism declined. The state of Unitarianism is similar.
The Church of Jesus Christ of Latter-day Saints in South Korea was established following the baptism of Kim Ho Jik in 1951. Studying nutrition in Cornell, he met a member of their faith, Oliver Wyman, and was struck with their doctrine. Upon joining the church and completing his degree, Kim travelled back to South Korea, started translations for materials, and helped the church gain official recognition.
In 2013, the Coptic Orthodox Church of Alexandria was first established in Seoul for Egyptian Copts and Ethiopians residing in South Korea.
Buddhism ( Bulgyo) entered Korea from China during the period of the three kingdoms (372, or the 4th century). Buddhism was the dominant religious and cultural influence in the Silla (668-935) and subsequent Goryeo (918-1392) states. Confucianism was also brought to Korea from China in early centuries, and was formulated as Korean Confucianism in Goryeo. However, it was only in the subsequent Joseon kingdom (1392-1910) that Korean Confucianism was established as the state ideology and religion, and Korean Buddhism underwent 500 years of suppression. Buddhism in the contemporary state of South Korea is stronger in the east of the country, namely the Yeongnam and Gangwon regions, as well as in Jeju.
There are a number of different schools in Korean Buddhism (? Daehanbulgyo), including the Seon (Korean Zen). The overwhelming majority of Buddhist temples in contemporary South Korea belong to the dominant Jogye Order, traditionally related to the Seon school. The order's headquarters are at Jogyesa in central Seoul, and it operates most of the country's old and famous temples, such as Bulguksa and Beomeosa.
Other Buddhist traditions in South Korea include the "Taego" and "Cheontae" lineages. Taego is a form of Seon (Zen), while the Choentae is a modern revival of the Tiantai lineage in Korea, focusing on the Lotus Sutra. Another lineage, the Jingak Order, is a form of Vajrayana Buddhism. Both the Jogye and Cheontae orders require their monastics to be celibate, while the Taego and Jingak orders allow for married priests.
|Jogye Order ()||735 (81%)|
|Cheontae Order ()||144 (16%)|
|Taego Order ()||102 (11%)|
|Beobhwa Order ()||22 (2%)|
|Seonhag-won ()||16 (2%)|
|Wonhyo Order ()||5 (1%)|
Won Buddhism ( Wonbulgyo) is a modern reformed Buddhism that seeks to make enlightenment possible for everyone and applicable to regular life. The scriptures and practices are simplified so that anyone, regardless of their wealth, occupation, or other external living conditions, can understand them.
Korean shamanism, also known as "Muism" ( Mugyo, "mu [shaman] religion") and "Sindo" () or "Sinism" ( Singyo "Way of the Gods"). is the native religion of the Koreans.[note 1] Although used synonymously, the two terms aren't identical: Jung Young Lee describes Muism as a form of Sindo - the shamanic tradition within the religion. Particularly akin to Japan's Shinto, contrarywise to it ad to China's religious systems, Korean Sindo never developed into a national religious culture.[clarification needed]
In contemporary Korean language the shaman-priest or mu (hanja: ?) is known as a mudang (Hangul: hanja: ) if female or baksu if male, although other names and locutions are used.[note 2] Korean mu "shaman" is synonymous with Chinese wu, which defines priests both male and female. The role of the mudang is to act as intermediary between the spirits or gods, and the human plain, through gut (rituals), seeking to resolve problems in the patterns of development of human life.
Central is interaction with Haneullim or Hwanin, meaning "source of all being", and of all gods of nature, the utmost god or the supreme mind. The mu are mythically described as descendants of the "Heavenly King", son of the "Holy Mother [of the Heavenly King]", with investiture often passed down through female princely lineage. However, other myths link the heritage of the traditional faith to Dangun, male son of the Heavenly King and initiator of the Korean nation.
Besides Japanese Shinto, Korean religion has also similarities with Chinese Wuism, and is akin to the Siberian, Mongolian, and Manchurian religious traditions. Some studies trace the Korean ancestral god Dangun to the Ural-Altaic Tengri "Heaven", the shaman and the prince. In the dialects of some provinces of Korea the shaman is called dangul dangul-ari. The mudang is similar to the Japanese miko and the Ryukyuan yuta. Muism has exerted an influence on some Korean new religions, such as Cheondoism and Jeungsanism. According to various sociological studies, Korea's type of Christianity owes much of its success to native shamanism, which provided a congenial mindset and models for the religion to take root.
In the 1890s, the last decades of the Joseon kingdom, Protestant missionaries gained significant influence, and led a demonisation of native religion through the press, and even carried out campaigns of physical suppression of local cults. The Protestant discourse would have had an influence on all further attempts to uproot native religion. The "movement to destroy Sindo" carried out in South Korea in the 1970s and 1980s, destroyed much of the physical heritage of Korean religion (temples and shrines), especially during the regime of President Park Chung-hee. There has been of a revival of shamanism in South Korea in most recent times.
Cheondoism ( Cheondogyo) is a fundamentally Confucian religious tradition derived from indigenous Sinism. It is the religious dimension of the Donghak ("Eastern Learning") movement that was founded by Choe Je-u (1824-1864), a member of an impoverished yangban (aristocratic) family, in 1860 as a counter-force to the rise of "foreign religions", which in his view included Buddhism and Christianity (part of Seohak, the wave of Western influence that penetrated Korean life at the end of the 19th century). Choe Je-u founded Cheondoism after having been allegedly healed from illness by an experience of Sangje or Haneullim, the god of the universal Heaven in traditional shamanism.
The Donghak movement became so influential among common people that in 1864 the Joseon government sentenced Choe Je-u to death. The movement grew and in 1894 the members gave rise to the Donghak Peasant Revolution against the royal government. With the division of Korea in 1945, most of the Cheondoist community remained in the north, where the majority of them dwelled. Only few thousands of them remain in South Korea today.
The social and historical significance of the Donghak movement and Cheondoism has been largely ignored in South Korea, contrarywise to North Korea where Cheondoism is viewed positively as a folk (minjung) movement.
Apart from Cheondoism, other sects based on indigenous religion were founded between the end of the 19th century and the early decades of the 20th century. They include Daejongism ( Daejonggyo), which has as its central creed the worship of Dangun, legendary founder of Gojoseon, thought of as the first proto-Korean kingdom; and a splinter sect of Cheondoism: Suwunism.
Jeungsanism ( Jeungsangyo) defines a family of religions founded in the early 20th century that emphasise magical practices and millenarian teachings. Part of it are more than a hundred "Jeungsan religions," including the now defunct Bocheonism: the largest in Korea is currently Daesun Jinrihoe (), an offshoot of the still existing Taegeukdo (), while Jeungsando () is the most active overseas. They show themes derived from Buddhism, Confucianism, Taoism, and Korean folk religion.
There are also a number of small religious sects, which have sprung up around Gyeryongsan ("Rooster-Dragon Mountain", always one of Korea's most-sacred areas) in South Chungcheong Province, the supposed future site of the founding of a new dynasty originally prophesied in the 18th century (or before). Japanese Tenriism ( Cheonligyo) also claims to have thousands of South Korean members.
According to Andrew Eungi Kim, there was a rise of new religious movements in the late 1900s which account for about 10 percent of all churches in South Korea. According to Kim, this is the outcome of foreign invasions, as well as conflicting views regarding social and political issues. Many of the new religious movements are syncretic in character.
The Unification Church or Unificationism ( Tongilgyo) is a new religious movement founded in South Korea in 1954 by Sun Myung Moon. Since its founding, the church has expanded throughout the world with most members living in East Asia.
Unificationist beliefs are derived from the Christian Bible and are explained in the church's textbook, the Divine Principle. It teaches that God is the creator and Heavenly Father, whose dual nature combines both masculinity and femininity and whose centre is true love.
The Unification Church has sponsored many organizations and projects over the years; including businesses, news media, projects in education and the arts, and political and social activism. The church was led by Moon until his death on September 3, 2012. At the time of Moon's death, it was reported that his widow Hak Ja Han would assume the leadership of the church. Their philosophy for establishing the Kingdom of Heaven is family centred.
In 2003, Korean Unification Church members started a political party in South Korea. It was named "The Party for God, Peace, Unification, and Home". In an inauguration declaration, the new party said it would focus on preparing for the reunification of the South and North Korea by educating the public about God and peace. A church official said that similar political parties would be started in Japan and the United States.
Only few contemporary South Koreans identify as adherents of Confucianism ( Yugyo). Korean intellectuals historically developed a distinct Korean Confucianism. However, with the end of the Joseon state and the wane of Chinese influence in the 19th and 20th century, Confucianism was abandoned. The influence of Confucian ethical thought remains strong in other religious practices, and in Korean culture in general. Confucian rituals are still practised at various times of the year. The most prominent of these are the annual rites held at the Shrine of Confucius in Seoul. Other rites, for instance those in honour of clan founders, are held at shrines found throughout the country.
Hinduism ( Hindugyo) is practiced among South Korea's small Indian and Nepali immigrant community. However, Hindu traditions such as yoga and Vedanta have attracted interest among younger South Koreans. There are two Hindu temples in the Seoul region, the Sri Radha Shyamasundar Mandir and the Sri Sri Radha Krishna temple, located on Seoul's outskirts.
Islam (? Iseullamgyo) in South Korea is represented by a community of roughly 40,000 Muslims, mainly composed by people who converted during the Korean War and their descendants and not including migrant workers from South and Southeast Asia. The largest mosque is the Seoul Central Mosque in the Itaewon district of Seoul; smaller mosques can be found in most of the country's major cities.
In addition to native Korean Muslims, there are around a hundred thousand foreign workers from Muslim countries, particularly Pakistanis and Bangladeshis.
The Jewish existence in South Korea effectively began with the dawn of the Korean War in 1950. At this time a large number of Jewish soldiers, including the chaplain Chaim Potok, came to the Korean peninsula. Today the Jewish community is very small and limited to the Seoul Capital Area. There have been very few Korean converts to Judaism ( Yutaegyo).
During Japan's colonisation of Korea (1910-1945), given the common Altaic origins of the two peoples, Koreans were considered to be outright part of the Japanese population, to be wholly assimilated. The Japanese studied and coopted native Sindo by overlapping it with their State Shinto (similar measures of assimilation were applied to Buddhism), which hinged upon the worship of Japanese high gods and the emperor's godhead. Hundreds of Japanese Shinto shrines were built throughout the peninsula.
This policy led to massive conversion of Koreans to Christian churches, which were already well ingrained in the country, representing a concern for the Japanese program, and supported Koreans' independence.
