I would defend the C of C. We are PART of Christ’s church, which by scriptural definition, is THE ONE TRUE CHURCH. I do not join my brethren in World Bible School saying that ONLY members of the Restoration movement, specifically those calling themselves the Church of Christ, will be going to heaven. God knows his children. I will not judge another man’s servant (Romans 14).
I agree that some CoC’s are a PART of the Lords church. But those hardline CoC’s who insist they are the One True Church and the only ones saved are not.
