The Lutheran Church—Missouri Synod began work in Finland in 1923. The LCMS was in altar and pulpit fellowship with The Confessional Lutheran Church of Finland from 1928 to 1999, at which time the Finnish church officially severed the relationship by convention vote.

The nature of mission partnership in Finland is largely historical, however, the two church bodies still maintain friendly relations.

Currently, the Confessional Lutheran Church of Finland reports a baptized membership of 318 in 14 congregations and preaching stations and a national staff of two pastors.
