Commentaries:
God gives the church the authority to disfellowship a member who is habitually committing sin or is a danger to the congregation (Matthew 18:17; Romans 16:17-18; I Corinthians 5:1-5, 9-13; II Thessalonians 3:6, 14; Titus 3:10-11). Every private association possesses power of this sort. For instance, the Boy Scouts of America has the right as a private group to dismiss a scoutmaster if he does not meet its stated qualifications. While this authority to dismiss members is assumed by private groups in America, the church has it by direct command from the Word of God.
The fundamental reasons for using the authority to disfellowship are to protect the church and to convey to the disfellowshipped person the seriousness of his actions. It is, in a sense, spiritual quarantine. The sinning member is separated from the rest of the congregation so he will not "infect" them, and he is given time and space to deal seriously with his problem.
Disfellowshipping does not—indeed cannot—take away a person's salvation; it does not consign him to the Lake of Fire. Jesus Christ is the Judge (John 5:22; Acts 17:31; II Timothy 4:8), not any minister or church council. All disfellowshipping does is exclude the rebellious member from fellowship with the church. However, if he does not repent and continues in his sinful practices, he may indeed be in danger of the second death (Revelation 20:14-15; see Hebrews 6:4-8; 10:26-31).

Putting Out Flawed Study Practices
Judging is a necessary part of life in the church. These verses show the apostle Paul's judgment of the man who was openly sinning while fellowshipping with the Corinthian congregation. Paul not only judged, he judged on the basis of the testimony and judgment of others he trusted! He then disfellowshipped the man without hearing the man's own testimony! This is the same man who wrote in Romans 14, "Who are you to judge another's servant?" (verse 4) and "But why do you judge your brother?" (verse 10). He obviously strongly believed that when the spiritual and moral integrity of a congregation was threatened by blatant sin, judgment was necessary.

Judgment, Tolerance, and Correction
The Corinthian church's coddling of this perversion gave the people of Corinth the appearance that God's people would allow this sin—a sin even unbelievers would never tolerate! Inside the church it gave the appearance that one could continue in sin and still remain part of the body. The apostle warns them that, just as a pinch of leaven will puff up a whole loaf of bread—or as one rotten apple will corrupt a whole barrel of them—so this sin, if allowed to continue, would ruin the entire church.

Abstaining From Evil
The Days of Unleavened Bread are a memorial to God's law and to His powerful deliverance from Egypt and bondage. Paul explains this significance to the Corinthians and the urgency attached to cease sinning. He says we should not even keep company with a brother involved in flagrant sin! Also, by ridding our homes of sin, we realize that overcoming sin is hard work!
