West Kalimantan Christian Church
The Singkawang Congregation was founded in the early 20th century, in the year 1906, by American evangelical missionary Charles M. Worthington.During the Japanese occupation, the Chinese people in West Borneo, especially the Christians faced persecution.After the end of World War II in 1950 the church received assistance from missionaries of China Inland Mission (now OMF International).Facing the political and social turbulence in Indonesia (Indonesian killings of 1965–66 while in the Transition to the New Order), then at the great plenary session in 1967, the synod decided to change the church name to West Kalimantan Christian Church (Chinese: 西加基督教會, Indonesian: Gereja Kristen Kalimantan Barat), abbreviated as GKKB.On 2 July 1988, the GKKB synod became a member of Council of Churches in Indonesia (CCI).
