Luwu Indonesian Protestant Church
Missionary work was primarily done in the mountainous regions due to prior Islamization of the coastal plain.However, a 1949 Islamist insurgency against the central government forced some Christian congregations to relocate to the coastal areas.Following the insurgency, the number of Christians in the area grew due to immigration from surrounding regions.[1] The GPIL was formed after several congregations split from the Toraja Church in 1965.It follows a Presbyterian organizational structure, with its congregations divided into six Classis: Nasakke, Lebang, Lambara, Kerepansu, Tabarano and Kalaena.
