The Presbyterian Church (USA) [PC (U.S.A.)] and the Korean Presbyterian Church in America (KPCA) are denominations with common roots and commitments in the Reformed tradition. The emotional ties are the legacy of their mission history. Protestant Christianity in Korea began through the sending of U.S. Presbyterian missionaries to Korea in 1885. Over the past century, Presbyterians in Korea have demonstrated phenomenal growth despite their difficult experiences of suffering. They have become genuine partners in mission and ecumenical engagement not only in Korea and Asia but also throughout the world.
