Trinity Lutheran Church is a scriptural, confessional, liturgical church of the Lutheran Church-Missouri Synod. Trinity serves the town of Ortonville and the surrounding areas, including Big Stone City and Milbank, South Dakota. We welcome all guests to our services as we proclaim the Gospel message - that Jesus Christ came into this world to live the life we cannot live for ourselves, to die the death we cannot die for ourselves, to be resurrected from the dead... all for the forgiveness of sins and the salvation of all who believe.
