What procedural steps are to be taken? Matthew 18:15-17 recommends the following steps: First, private rebuke (Mt. 18:15) - do it gently, in love, out of compassion, seeking to encourage; the purpose for private rebuke is to resolve the problem without fueling unnecessary gossip. Second, if private rebuke is unsuccessful, plural rebuke (Mt. 18:16; see also Deut. 17:6; 19:15; Num. 35:30) - who are these others? church leaders? people who know the person? people who know of the sin? Third, if plural rebuke is unsuccessful, public rebuke (Mt. 18:17). Fourth, if public rebuke is unsuccessful, 'excommunication' (Mt. 18:17; 1 Cor. 5:11; Titus 3:10; possibly 2 Thes. 3:14). Fifth, if repentance occurs, restoration to fellowship and reaffirmation of love (2 Cor. 2:6-8; 2 Thes. 3:14-15; Gal. 6:1). Sixth, verses 18-20 affirm that whatever decision is made in the matter, whether the offending person is 'bound' or 'loosed', reflects the will of God in heaven. The promise 'is that God will provide wisdom, guidance, and power for decision-making to the church that is united in its powers regarding the matters of church discipline' (Laney, A Guide to Church Discipline, 76). Thus, the verdict of heaven, so to speak, is consonant with that of the church, before whom the matter was adjudicated.
