The Missionary Church is an evangelical Christian denomination of Anabaptist origins with Wesleyan, Pietist, and Keswickian influences.
The Missionary Church is a Trinitarian body that believes the Bible is the inspired Word of God and authoritative in all matters of faith; that "salvation is the result of genuine repentance of sin and faith in the atoning work of Christ"; and that the "church is composed of all believers in the Lord Jesus who have been vitally united by faith to Christ". They hold two Christian ordinances: baptism (by immersion) and the Lord's Supper, which are outward signs, not a means of salvation.
The Missionary Church has diverse roots, especially in Anabaptism (directly through the Mennonites), German Pietism, the holiness movement, and American evangelicalism, (and to a smaller degree fundamentalism and Pentecostalism). The preamble to their Constitution references this by stating:
In the late 19th century, several Mennonite preachers embraced pietism and revivalism, and were excluded from their conferences. Among the leaders were Solomon Eby (1834–1929) of Ontario, William Gehman (1827–1917) of Pennsylvania, Daniel Brenneman (1834–1919) of Indiana, and Joseph E. Ramseyer (1869–1944). These brethren gradually found one another and their movements merged. Daniel Brenneman and Solomon Eby established the Reformed Mennonites in 1874. The Reformed Mennonites joined with some other expelled Mennonite members (called the New Mennonites) and formed the United Mennonites. In 1879 the followers of William Gehman (called Evangelical Mennonites) merged with the United Mennonites, creating the Evangelical United Mennonites. In 1883 a group from Ohio (called Brethren in Christ or Swankites) joined the movement. The denomination became the Mennonite Brethren in Christ on December 29, 1883 in Englewood, Ohio. The Mennonite Brethren in Christ changed their name to the United Missionary Church in 1947.
