My wifes Grandfather was a DOC minister before WW II.
Up until the Sixties the Restoration Movement consisted of the Disciples of Christ and the churches of Christ. Both groups were composed of independent churches. The liberal branches of the DoC broke off from the conservative branch in the Sixties, and formed the DoC Denomination, with the conservatives now labeled the independent Christian Churches. I am ordained in the latter, but have my membership in the church of Christ.
Liberal is an understatement!
They are out and out Marxists to the core. They make the Unitarians look conservative.
