• noun A Baptist denomination of Christians founded in the United States by Thomas and Alexander Campbell, father and son (originally Irish Presbyterians), aud first organized by the latter as a separate body in western Virginia in 1827. The members of this denomination call themselves Disciples of Christ, and they are also known as Campbellites, or simply Christians, the last of which names is more distinctively appropriated by another denomination. (See Christian, 5.) Their original purpose was to find a basis upon which all Christians could unite, and hence they rejected all formulas or creeds but the Bible itself; but their belief is generally orthodox or evangelical, including the doctrine of the Trinity. In general, the only terms of admission to the denomination are the acceptance of the Bible as a sufficient and infallible rule of faith and practice, and adult baptism by immersion. In church government they are congregational. They have representatives in Great Britain and its colonial possessions, but exist in the greatest numbers in the western and southwestern portions of the United States.
