Any Christian who sets himself up as a teacher in the church of Christ and publicly teaches anything thereby opens himself up for criticism by others (cf. James 3:1). If they think what he is teaching is harmful to the church, they have an obligation to point it out just as widely as it was taught. Such public warning or debate on the topic should not be considered a personal attack at all. The teacher’s plea that a critic should first have come to him about his disagreement on the basis of Matthew 18:15 does not hold. This passage has to do with personal wrongs known only between the two, who should privately discuss the matter that separates them. What a critic of a public teaching does in pointing out his disagreement with that teaching has nothing to do with personal affronts or lack of reconciliation; he is simply disagreeing at the same public level as that on which the teaching was given in the first place. — Dr. Jay E. Adams, Grist from Adam’s Mill, 69
