Presbyterian Church of Korea

The Presbyterian Church of Korea (PCK; Korean: 대한예수교장로회; Hanja: 大韓예수敎長老會), also known by the abbreviation Yejang (예장), is a Calvinist Protestant denomination based in South Korea that adheres to the Westminster Confession of Faith.

Korean Presbyterianism originated in the early 1880s with the establishment of the Sorae Church by Seo Sang-ryun in 1884, following his conversion by Scottish Presbyterian missionaries.

As the Presbyterian mission expanded, the need grew for Korean pastors to serve congregations and provide theological education. In 1907, Presbyterians from the United States, Australia, and Canada established the first theological seminary in Korea, located in Pyongyang. In 1907, the Presbyterian Church of Korea organized its first presbytery and established a governing council.

Since the 1950s, the Presbyterian Church of Korea has experienced a series of schisms, resulting in multiple separate denominations such as the Presbyterian Church of Korea (TongHap) and the Presbyterian Church in Korea (HapDong), primarily over differences in ecclesiology and relations with ecumenical bodies. As of 2019, there were 286 branches in South Korea, with approximately four million church attendees. Numerous denominations that emerged from these schisms continue to incorporate "Presbyterian Church of Korea" in their official names.
