The LCMS 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 parter church in 1960.
The Confessional Lutheran Church of Chile (IELCHI) partners with LCMS World Mission and other partner church bodies in Latin America to educate pastors and other mission leaders through a Mission Training School. LCMS World Mission also helps support their urban outreach in Santiago.
LCMS World Relief and Human Care has supported nutrition, sanitation and anti-drug education programs in Chile, and, in partnership with LCMS World Mission, 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.
