The Campbell wing of the movement was launched when Thomas Campbell published the
Declaration and address of the Christian Association of Washington in 1809. The Presbyterian Synod had suspended his ministerial credentials. In
The Declaration and Address he set forth some of his convictions about the church of Jesus Christ, as he organised the
Christian Association of Washington, in
Washington County, Pennsylvania, not as a church but as an association of persons seeking to grow in faith. On 4 May 1811, the Christian Association reconstituted itself as a congregationally governed church. With the building it constructed at Brush Run,
Pennsylvania, it became known as
Brush Run Church. Thomas and his son
Alexander worked within the Redstone Baptist Association during the period 1815 through 1824. While both the Campbells and the Baptists shared practices of baptism by immersion and
congregational polity, it was soon clear that the Campbells and their associates were not traditional Baptists. Within the Redstone Association, some of the Baptist leaders considered the differences intolerable when Alexander Campbell began publishing a journal,
The Christian Baptist, which promoted reform. The Campbells anticipated the conflict and moved their membership to a congregation of the
Mahoning Baptist Association in 1824. ==Theological influences==
