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).
