Private or personal offenses are to be adjusted in strict accordance with Christ’s directions in Matthew 18:15-17. Christ lays down four distinct steps, which are always to be taken in the order given by Him, and not in a reversed order. First: the aggrieved party, if the other does not, is to take the initiative in seeking a private interview with the supposed offender; if he fails to do so, he himself becomes an offender, as he has violated the law of Christ. The privacy of the interview is highly important; the object is, not altercation, but to gain an offending brother. Perhaps the offending brother is laboring under a mistake; the other brother may not have intended to offend him, and may not be conscience of having done so, or he may not have had an opportunity of explaining his conduct. A private interview conducted in a calm brotherly spirit may and should give full mutual satisfaction. If in such an interview the offense is denied, and there are no witnesses of the offense, the next step cannot be taken; for then the complaining party would become an offender, having published a charge which can not be proved. Absence of proof will leave him no recourse but in private admonition and the patient committal of the matter to Providence.
Second: If the first step fails, and the offense can be proved, then one or two other disinterested and judicious members are to be chosen as witnesses and mediators, and the whole case is to be considered before them. They may be able to discover what is right between the members at variance, and the latter may be willing to yield to their decision. If the “one or two more” consider the offense as not real or as satisfactorily removed, the aggrieved party, though unsatisfied, can not take the third step; for the offender has “heard them,” and the accuser ought to be satisfied with the judgment of the brethren selected by himself. Third: if the second step fails, the case, after due notification of the parties, is to be laid before the church, the proof adduced, and the opportunity given for defense. Here the united wisdom and influence of the whole church is brought to bear to reconcile the difference and judge between parties. Fourth: If the party judged by the church to be in fault still refuses to make amends, it is evident that his heart is fully set in him to do evil, and must be excluded from the church; for his refusal to hear the body proves his contempt for the brethren, and they are therefore compelled to withdraw their fellowship from him. If this important law of the Great Head of the church were properly executed, long continued personal feuds, with their disastrous results, bitterness and factions, would be prevented. Differences between members in regard to worldly affairs are expressly forbidden by the inspired Apostle Paul (1 Cor. 6:1-11) to be carried before worldly courts, but must be referred to the judgment of the wise members of the church, the least esteemed of whom, if they have the Spirit of Christ, are better qualified to judge between brethren.
Saints are finally to judge the wicked world and angels, and are certainly qualified to judge in small temporal matters. Christians should not contend before the ungodly, and thus bring reproach upon the cause of Christ. Besides, differences among men are often decided in worldly courts, not according to right and equity, but by legal quibbles and technicalities; whereas the children of God should always desire, in reference to their affairs, a judgment according to the equity and the Spirit of Christ. —In regard to moral or public offenses against the order, faith and purity of the church, such as neglect of church obligations, heresy, idolatry, immorality, intemperance, railing and extortion (1 Cor. 5:11; Titus 3:10; 2 Peter 2; Heb. 10:25), these may be divided into minor and gross public offenses. Minor public offenses, such as a member may be led, under strong and sudden temptation, to commit only once, and such as do not greatly scandalize the cause of Christ, are to be treated according to Paul’s direction in Galatians 6:1; these erring members are to be restored by the spiritual in the spirit of sympathizing meekness, as all are liable thus to be tempted; in these cases the method of procedure laid down by Christ for personal offenses (Matthew 18:15-17) is in spirit to be observed (Titus 3:10). Christian tenderness may also here succeed in gaining a brother. But, in the case of gross, deliberate, habitual public offenses, or such as greatly scandalize the church, where the evidence is public and unmistakable, there should be, though in a spirit of sorrow and not of bitterness, a prompt absolute exclusion, as the Apostle divinely enjoined in regard to the Corinthian offender (1 Cor. 5); any steps taken to bring such an offender to repentance and restoration should be taken afterwards (2 Cor. 2:1-11). A confession and promise of reformation are not enough to be required of this class of offenders. They should, for the honor of Christ, be at once cut off; and, if they afterwards, by a godly conduct and conversation, bring forth fruits meet for repentance, and prove genuineness of their sorrow and reformation, then they may be restored (2 Cor. 7:8-12; Matthew 3:8; Acts 26:20). The rule in Luke 17:3-4, plainly applies only to personal or private offenses, which do not bring scandal upon the church—not to public or moral offenses which seriously reproach the cause of Christ. The latter are offenses which the church can not forgive; but, when assured that God has forgiven the offender, she may then receive him back into membership. —In the apostolic church the Elders or presbyters are sometimes called Bishops or overseers or rulers of the flock, and therefore had the special responsibility of maintaining the discipline of the church (Acts 20:17 & 28; 1 Tim. 3:4-5 & 5:17; Heb. 13:7, 17, & 24).
Against an Elder an accusation was not to be received but before two or three witnesses (1 Tim. 5:19), because his office is a very presumption in his favor, and because, as a minister, he is peculiarly exposed to malice. An Elder, to be efficient, must be “blameless” (1 Tim. 3:2; Titus 1:6-7). A tender, faithful, scriptural discipline, like that observed by the people of God in the apostolic age, is of the highest and most vital importance for the welfare of the church; the neglect of such discipline is the most potent cause of evil in the church. “The object of faithful church discipline is threefold. First: The glory of God, whose great and holy name is dishonored by the evil principles or evil practices of church members, and whose honor is vindicated by their prompt and proper correction. Second: The preservation of the church from corruption and destruction; the old leaven of wickedness must be purged out, to preserve the whole body from infection; evil communications corrupt good manners; lepers were to be put out of the camp, so as not to infect others, and so erroneous persons, whose words eat as a canker (2 Tim. 2:17), must be removed from the communion of gospel churches; a church of Christ is like a garden or vineyard, which if not cared for, will be overrun with thorns and nettles and weeds, but, by a proper and timely discipline, the weeds eradicated, and the withered branches are gathered and cast out. Third: The good of the offending parties, who, if real children of God, are, by proper discipline brought to shame and repentance for their sins, and an acknowledgment of them, when they are to be received again with all love and tenderness, and to be comforted, that they might not be swallowed up with over-much sorrow.”...
