I have seen others ask similar questions about family church discipline, but have never seen a solid biblical answer to this one, so I'm excited to hear what my wiser brothers and sisters in Christ have to say! Let's use this example: A father (who is supposed to be the leader of the household) claims to be a Christian but holds incorrect teachings: Word Faith, prosperity gospel, mystical meditation and emphasizes psychology love over Biblical law. Over 30 years, he shows no fruit at all but is verbally abusive and engulfed in pride and selfishness. Being mislead himself, he tries to teach these wrong beliefs to his Reformed Christian wife and kids, so he is a type of false teacher. Now, if he does NOT go to church, what can be done if he is living in ongoing sin? 1) Can Mt 18:15-20, 1 Cor 5:1-13, Gal 6:1, 2 Thess 3:6-15, James 5:19-20, 1 John 5:16-21 apply? If yes, on what basis since he doesn't go to church? Must his Reformed Christian family "excommunicate him?" How can he be held accountable for his ongoing sin? 2) Or if these verses do not apply to his situation, on what basis? Is it because some may consider him "not really a true Christian?" Are we allowed to even make this distinction in such a case? Or is it because he doesn't go to church that these verses don't apply? Is there no way to hold him accountable at all? What is a Christian family to do biblically? 3) Should the family treat him like a backsliding disobedient Christian (holding him accountable in some way for his sins according to above verses?) or a lost unsaved soul who needs the gospel (forgiving all sins and ministering to him) or a false teacher (although he is only teaching members of his direct family and not the church)? Thanks for your feedback!
