Christianity in Korea

The practice of Christianity in Korea is marginal in North Korea, but significant in South Korea, where it revolves around two of its largest branches, Protestantism and Catholicism, accounting for 8.6 million and 5.8 million members, respectively. Catholicism was first introduced during the late Joseon Dynasty period by Confucian scholars who encountered it in China. In 1603, Yi Gwang-jeong, a Korean diplomat, returned from Beijing carrying several theological books written by Matteo Ricci, an Italian Jesuit missionary to China. He began disseminating the information in the books, introducing Christianity to Korea. In 1758, King Yeongjo of Joseon officially outlawed Catholicism as an "evil practice." Catholicism was reintroduced in 1785 by Yi Seung-hun and since then French and Chinese Catholic priests were invited by the Korean Christians. Joseon royalty saw the new religion as a subversive influence and persecuted its earliest followers in Korea, culminating in the Catholic Persecution of 1866, in which 8,000 Catholics across the country were killed, including nine French missionary priests. Later in the nineteenth century, the opening of Korea to the outside world gradually brought more religious toleration toward Christians. Sorae Church, which was the first Protestant church in Korea, was established by Seo Sang-ryun on May 16, 1883. Lee Soo-jung, one of the first Christians in Korea was baptized in Japan on April 29, 1883, and wrote an English article on the Missionary Review of the World to urge more American missionaries to enter Korea on December 13, 1883. Robert Samuel Maclay and Horace Newton Allen entered Korea one year later in 1884. Horace Allen was a North Presbyterian missionary who later became an American diplomat. He served in Korea until 1905, by which time he had been joined by many others. The growth of both denominations was gradual before 1945. In that year, approximately 2% of the population was Christian. Rapid growth ensued after the war, when Korea was freed from Japanese occupation by the Allies: by 1991, 18.
