The Lutheran Church—Missouri Synod began supporting mission work in Chile in 1960. The Evangelical Lutheran Church of Chile, now known as the Confessional Lutheran Church of Chile, became a partner church in 1960.
The Confessional Lutheran Church of Chile (IELCHI) partners with the LCMS and other partner church bodies in Latin America to educate pastors and other mission leaders through a Mission Training School. The LCMS also helps support their urban outreach in Santiago.
The LCMS has supported nutrition, sanitation and anti-drug education programs in Chile, and the LCMS responded to the 8.8-magnitude earthquake and ensuing tsunami that struck central Chile in February 2010.
The Confessional Lutheran Church of Chile is a sister/partner church of the LCMS. It works closely with the Evangelical Lutheran Church of Argentina, which operates a Lutheran seminary where many Chilean pastors are trained.
The church has more than 170 members.
