The Evangelical Lutheran Church in America (ELCA) consists of over four million baptized members and more than 10,000 congregations that are grouped into 65 synods. The ELCA was formed in 1988 as a merger of three Lutheran denominations. St. Mark is one of 139 congregations in the Western Iowa Synod. The synod office is located here in Storm Lake and is served by Bishop Rodger Prois. The ELCA headquarters is in Chicago, Illinois; our Presiding Bishop is Elizabeth Eaton. Our Lutheran companion synods are the Southern Diocese of Tanzania and the Evangelical Lutheran Church in Chile (IELCH).
