Part Calvinist? LOL! You originally said "Calvinist to the core." Big difference. The Roman Catholic church teaches that there is one God in essence or nature, yet three distinct persons, the Father, Son and Holy Spirit. This is referred to as the Trinity or the Godhead. I believe that. Does that make me part Roman Catholic? Muslims believe in the virgin birth of Jesus. I believe in the virgin birth of Jesus. Does that make me part Muslim? So because I'm not a five point Calvinist but don't believe that John Calvin was 100% wrong about everything, that makes me part Calvinist? Even leaders of cults and false religions may be right about "something".
In regards to being a Campbellite. Historically, Churches of Christ in the United States have roots in the American Restoration Movement, and were recognized as a distinct religious group by the U.S. Religious Census of 1906. The Restoration Movement began on the American frontier during the Second Great Awakening of the early 19th century under the leadership of Thomas and Alexander Campbell, Walter Scott, and Barton W. Stone. Those leaders had declared their independence from their Presbyterian roots, seeking a fresh start to restore the New Testament church, and abandoning creeds. They did not see themselves as establishing a new church. Rather, the movement sought the restoration of the church and "the unification of all Christians in a single body patterned after the church of the New Testament." The names "Church of Christ," "Christian Church" and "Disciples of Christ" were adopted by the movement because they believed these terms to be biblical.
A Campbellite is a term referring to adherents of certain religious groups that have historic roots in the Restoration Movement, among whose most prominent 19th century leaders were Thomas and Alexander Campbell. Do you deny that the Churches of Christ have their roots in the American Restoration Movement and that the Restoration Movement began on the American frontier during the Second Great Awakening of the early 19th century under the leadership of Thomas and Alexander Campbell, Walter Scott, and Barton W. Stone?
