Discipline by Churches
Church discipline rarely occurs in our current church environments. This is a tragedy because sin can become like a cancer cell that grows and threatens the health of the whole church body. Today we even see our legislators claiming to be Christians and yet pushing for legislation that is contrary to the positions advocated by their church. Sinful behavior has all types of ramifications for the church which is why the Bible addresses its importance. When church leaders allow it to fester, sinful behavior becomes the national problem that it is today.
Question: "What does the Bible say about church discipline / excommunication?"
Answer: Excommunication is the formal removal of an individual from church membership and the informal separation from that individual. Matthew 18:15-20 gives the procedure and authority for a church to do this. It instructs us that one individual (usually the offended party) is to go to the offending individual. If he/she does not repent, then two or three go to confirm the situation and the refusal to repent. If there is still no repentance, it is taken before the church. This process is never “desirable,” just as a father never delights in having to discipline his children. Often, though, it is necessary. The purpose is not to be mean-spirited or to display a “holier than thou” attitude. Rather, the goal is the restoration of the individual to full fellowship with both God and other believers. It is to be done in love toward the individual, in obedience and honor to God, and in godly fear for the sake of others in the church.
The Bible gives an example of the necessity of excommunication in a local church—the church at the city of Corinth (1 Corinthians 5:1-13). In this passage, the apostle Paul also gives some purposes behind the biblical use of excommunication. One reason (not directly found in the passage) is for the sake of the testimony of Christ Jesus (and His church) before unbelievers. When David sinned with Bathsheba, one of the consequences of his sin was that the name of the one true God was blasphemed by God's enemies (2 Samuel 12:14). A second reason is that sin is like a cancer; if allowed to exist, it spreads to those nearby in the same way that “a little yeast works through the whole batch of dough” (1 Corinthians 5:6-7). Also, Paul explains that Jesus saved us so that we might be set apart from sin, that we might be “unleavened” or free from that which causes spiritual decay (1 Corinthians 5:7-8). Christ's desire for His bride, the church, is that she might be pure and undefiled (Ephesians 5:25-27).
Excommunication is also for the long-term welfare of the one being disciplined by the church. Paul, in 1 Corinthians 5:5, states that excommunication is a way of delivering the unrepentant sinner “over to Satan, so that the sinful nature may be destroyed and his spirit saved on the day of the Lord.” This means that excommunication can somehow involve God’s using Satan (or one of his demons) as a disciplinary tool to work in the sinner's life physically to bring about true repentance in his/her heart.
Hopefully the disciplinary action of the church is successful in bringing about godly sorrow and true repentance. When this occurs, the individual can be restored to fellowship. The man involved in the 1 Corinthians 5 passage repented, and Paul encouraged the church to restore him to fellowship with the church (2 Corinthians 2:5-8). Unfortunately, disciplinary action, even when done in love and in the correct manner, is not always successful in bringing about such restoration. But even when church discipline fails to achieve its goal of bringing repentance, it is still needed to accomplish the other good purposes mentioned above.
We have all likely witnessed the behavior of a young boy who has been allowed to do as he pleases with no consistent discipline. It is not a pretty sight. Nor is such parenting loving, for it dooms the child to a dismal future. Such behavior will keep the child from forming meaningful relationships and performing well in any kind of setting. Similarly, discipline in the church, while never enjoyable or easy, is not only necessary, but loving as well. Moreover, it is commanded by God.
