The denomination known as the United Christian Church is a small evangelical body of Christians with roots in the pietistic movement of Martin Boehm and William Otterbein. This group may often be confused with local congregations and churches of other denominations that also use the name United Christian Church. Those who began the United Christian Church separated from the Church of the United Brethren in Christ between the years of 1862 to 1870 over doctrinal differences of opinion. Led by Rev. George W. Hoffman, for a number of years the separatists were known as Hoffmanites. Hoffman opposed infant baptism, membership in secret societies, slavery, and the bearing of arms in war. He and others believed that some resolutions of the East Pennsylvania Conference of United Brethren were weak on the issue of bearing of arms, to the point of allowing members to do so if they chose.
