The denomination was a result of the split of the Presbyterian Church in Korea (Koshin) due tensions in the KoRyu Seminary.
Pastor Park Yun-Sun moved to Seoul and founded the Reformed Theological Seminary.
To avoid division Park returned to Koshin but Chung Hun-Teuk took over as the director in the Seminary.
The denomination has close contact with conservative Reformed churches in Japan, Netherlands and the United States.
Since 1977 the leading figure of the church has been Yoo Don-Sik, who also directs the Reformed Theological Seminary too.
