Unlike the Dutch Mission in West Java (cf. Gereja Kristen Pasundan, no. 15) the 19th-century mission in East Java did not work among people of Chinese descent. Christianity among the Chinese in East Java has its origins in mission work by the Chinese themselves (cf. Gereja Kristen Indonesia, no. 7) and, in the first decades of the 20th century, by the mission of American Methodists (1905-1928).In 1928 this mission was taken over by a small Calvinist church in the Netherlands. At the time there was only one Chinese congregation, in Surabaya, which was divided into three sections according to the Chinese dialects spoken. The style is loosely based on Presbyterian. Services are held Fridays & Saturdays at 7.00, and Sundays at 7.00 a.m.,5.00 & 8.30 p.m.
