Christianity in South Korea: History, Growth, and Cultural Impact
While religious practice remains marginal in North Korea, Christianity has become a significant pillar of society in South Korea. With a diverse landscape of denominations, the faith has evolved from a persecuted minority to a major cultural and social force. As of 2024, approximately 31% of the South Korean population identifies as Christian.

The Historical Roots of Faith in Korea
The introduction of Christianity to the Korean peninsula followed different paths for Catholicism and Protestantism. Catholicism was first introduced during the late Joseon Dynasty through Confucian scholars who encountered the faith in China. In 1603, the politician Yi Su-gwang brought theological books written by the Italian Jesuit Matteo Ricci from Beijing, beginning the dissemination of Christian thought.
However, the early adoption of Catholicism faced severe resistance. In 1787, King Jeongjo officially outlawed the religion, labeling it a heretical "evil practice." This era of persecution was violent; the Catholic Persecution of 1866 saw the deaths of 8,000 Catholics, including nine French missionary priests. It was not until the late 19th century, as Korea opened to the world, that religious toleration began to emerge.
The Rise of Protestantism
Protestantism arrived later, marked by the establishment of the Sorae Church—the first Protestant church in Korea—by Seo Sang-ryun on May 16, 1883. The movement gained momentum through the efforts of early converts like Lee Soo-jung and the arrival of American missionaries such as Robert Samuel Maclay and Horace Newton Allen in 1884. The Anglican Church of Korea also established roots in 1890, with the Nae-dong Anglican Church founded in 1891.
Growth and Modern Expansion
The demographic landscape of Korean Christianity shifted dramatically in the 20th century. In 1945, Christians made up only about 2% of the population. Following the end of Japanese occupation, the faith experienced rapid growth. By 1991, Protestants accounted for 18.4% of the population, while Catholics represented 6.7%.
In recent decades, the Catholic Church has seen steady increases, including a 70% membership rise in the decade leading up to 2007. While other groups like Eastern Orthodoxy remain small (approximately 0.005%), and various unorthodox sects have emerged, the mainstream denominations continue to exert significant influence.
| Group | Estimated Population/Percentage | Notes |
|---|---|---|
| Total Christian Population | 31% (as of 2024) | Combined Protestant and Catholic |
| Protestants | 8.6 million | Predominantly Presbyterian |
| Catholics | 5.8 million | Significant growth noted through 2007 |
| Eastern Orthodox | 4,000 adherents | Approximately 0.005% of population |
Christianity and Korean Nationalism
One of the most profound drivers of Christian acceptance was the faith's connection to Korean nationalism during the Japanese occupation (1910–1945). As Japan implemented policies of cultural assimilation—including banning the Korean language in 1938—the church became a sanctuary for national identity.
The 1919 March 1st Movement, a pivotal moment in the struggle for independence, included 15 Protestant signatories among its 33 leaders. Similarly, the Catholic-led "Ulmindan" movement emerged during this period. This alignment with the cause of independence helped forge a deep bond between the Christian community and the Korean people.
Global Missionary Impact
South Korea has transformed into a global center for evangelism. By 2007, reports indicated that Korea had 16,000 missionaries working overseas, a figure second only to the United States. This number has continued to climb, with estimates reaching 30,000 commissioned missionaries in recent years.
The Presbyterian Church in Korea (Hapdong) is particularly active, sending approximately 3,000 missionaries abroad. South Korean missionaries serve in diverse and often challenging environments, including the 10/40 Window, which refers to regions that are often more resistant to Western influence.
