I have preached God's truth, so far as I know it, and I have not been ashamed of its peculiarities. That I might not stultify my testimony, I have cut myself clear of those who error from the faith, and even from those who associate with them.
Charles HaddonFor Christians to be linked in association with ministries who do not preach the gospel of Christ is to incur moral guilt. A Union which can continue irrespective of whether its member churches belong to a common faith is not fulfilling any scriptural function. The preservation of a denominational association when it is powerless to discipline heretics cannot be justified on the grounds of the preservation of 'Christian unity'... It is error which breaks the unity of churches, and to remain in a denominational alignment which condones error is to support schism.
