Paul proceeded to deal with the larger issue of the believer's relationship to fornicators inside and outside the church. He did this so his readers would understand their responsibility in this area of their lives in their immoral city and abandon their arrogant self-righteousness.
5:9 Paul had written this congregation a previous letter that is no longer extant.119In it he urged the Corinthians to avoid associating with fornicators. The same Greek word, pornois, occurs here as in verse 1. In view of this instruction the Corinthians' toleration of the incestuous brother in the church was especially serious.
5:10 However, Paul hastened to clarify that in writing what he had he did not mean a believer should never associate with fornicators outside the church. He did not mean either that they should avoid contact with unbelievers who were sinful in their attitudes and actions toward people and God. Even our holy Lord Jesus Christ ate with publicans and sinners. Such isolationism would require that they stop living in the real world and exist in a Christian ghetto insulated from all contact with unbelievers. This approach to life is both unrealistic and unfaithful to God who has called us to be salt and light in the world (Matt. 5:13-16; 28:19-20). Many Christians today struggle with an unbiblical view of separation that tends more toward isolationism than sanctification.
In 2 Thessalonians 3:14 Paul used the same phrase (Gr. sunanamignusthai, lit. mix up together), translated "to associate with"(v. 9), with regard to busybodies in the church. There not associating was to be the last resort of faithful believers in their social dealings with their disobedient brethren (cf. 1 Thess. 4:11-12; 5:14). They were not to treat them as enemies, however, but as brothers. Probably Paul had the same type of disciplinary behavior in view here. Some interpreters view this as excluding the offender from the community of believers gathered for worship.120I tend to think it means not socializing with such a person.
5:11 Paul now clarified that he had meant that the Corinthian Christians should not associate with such a person if he or she professed to be a believer. The Greek phrase tis adelphos onomazomenosliterally means one who bears the name brother. The translation "so-called brother"(NASB) implies that the sinner was only a professing Christian. Only God and that person knew for sure whether he or she was a genuine Christian or not.121In particular they were to exclude such a person from table fellowship with the other Christians in the church.
In the early history of the church eating together was a large part of the fellowship that the Christians enjoyed with one another (cf. Acts 2:46-47; 6:1; et al.). To exclude a Christian from this circle of fellowship would have made a much stronger statement to him than it normally does today in American church life.
"The Apostle is not thinking of Holy Communion, in which case the mede["not even"] would be quite out of place: he is thinking of social meals; Do not invite him to your house or accept his invitations.'"122
This exclusion was a strong form of discipline that Paul designed to confront the offender with his or her behavior and encourage him or her to repent. Some modern congregations have adopted the policy of excluding such offenders from participation in the Lord's Supper. However this form of discipline does not carry much impact when a congregation observes the Lord's Supper only monthly or quarterly. Modern church leaders need to give careful thought to what form of discipline would have the same impact and effect on such a person in their particular society.
Paul's list of sins here seems to be suggestive rather than comprehensive (cf. 6:9-10). It includes fornicators, the greedy, idolaters, people who abuse others verbally, drunkards and perhaps others addicted to enslaving substances, and swindlers. The failure of many church leaders to discipline professing Christians who practice these things today is a sad commentary on the carnality of the modern church.
5:12 Paul's authority as an apostle did not extend to judging and prescribing discipline on unbelievers for their sins. He did, of course, assess the condition of unbelievers (e.g., Rom. 1; et al.), but that is not what is in view here. His ministry and the ministry of other Christians in judging and disciplining sin took place only within church life. Judging means more than criticizing. It involves disciplining, too, as the context shows.
5:13 Judging and disciplining unbelievers is the Lord's work. Obviously this does not mean that Christians should remain aloof when justice needs maintaining in the world. God has delegated human government to people as His vice-regents (e.g., Gen. 9:5-6). As human beings Christians should bear their fair share of the weight of responsibility in these matters. The point here is that the Corinthians and all Christians should exercise discipline in church life to an extent beyond what is our responsibility in civil life.
Paul did not explain the objective in view in church discipline in this passage. Elsewhere we learn that it is always the restoration of the offender to fellowship with God and His people (2 Cor. 2:5-11). It is also the purity of the church.123
Chapter 5 deals with the subject of immoral conduct by professing Christians.124The first part (vv. 1-8) contains directions for dealing with a particular case of fornication that existed in the church. The Corinthian Christians were taking a much too permissive attitude toward sin. The second part (vv. 9-13) clarifies our duty in all instances of immoral conduct inside and outside the church.
