The Central Sulawesi Christian Church is the largest Christian church in Central Sulawesi, Indonesia. The church was established in the early 1893 through the mission work of the Dutch Reformed Church (Nederlands Hervormde Kerk — A.C. Kruyt and N. Adriani — ) and became an independent denomination in 1947 when Indonesia declared its independence from the Netherlands and ordered all Dutch nationals to go home. November 1993, there was in Tentena a celebration feast for 100 years Christianity. The GKST (Central Sulawesi Christian Church) now has over 320 congregations spread throughout the province of Central Sulawesi as well as the northern part of South Sulawesi province. The church is headquartered in the town of Tentena, at the northern end of Lake Poso.
