Albert Barnes Commentary 1 Corinthians 5:4

"in the name of our Lord Jesus, ye being gathered together, and my spirit, with the power of our Lord Jesus," — 1 Corinthians 5:4 (ASV)

In the name, etc. By the authority, or on behalf, or acting by his commission or power (2 Corinthians 2:10). See the notes on Acts 3:6.

This does not refer to Paul alone in declaring his opinion, but means that they were to be assembled in the name of the Lord Jesus, and that they were to proceed to exercise discipline by his authority. The idea is that the authority to administer discipline is derived from the Lord Jesus Christ, and is to be exercised in his name, and to promote his honor.

When ye are gathered together. Or, "You being assembled in the name of the Lord Jesus." This is to be connected with the previous words, and means the following:

1. That they were to be assembled for the purpose of administering discipline; and
2. That this was to be done in the name and by the authority of the Lord Jesus.

And my spirit (1 Corinthians 5:3) means as if I were with you; that is, with my declared opinion, knowing what I would advise if I were one of you, or I being virtually present with you by having delivered my opinion. It cannot mean that Paul's soul would be really present with them; but that, knowing his views and feelings, what he would do, and his love for them, they could act as if he were there.

This passage proves that discipline belongs to the church itself; and so deep was Paul's conviction of this, that even he would not administer it without their concurrence and action. And if Paul would not do it, and in a case, too, where bodily pains were to be inflicted by miraculous agency, assuredly no other ministers have a right to assume the authority to administer discipline without the action and the concurrence of the church itself.

With the power, etc. This phrase is to be connected with the following verse. "I have determined what ought to be done. The sentence which I have passed is this: You are to be assembled in the name and authority of Christ. I shall be virtually present. And you are to deliver such a one to Satan, by the power of our Lord Jesus Christ." That is, it is to be done by you; and the miraculous power which will be demonstrated in the case will proceed from the Lord Jesus. The word power (dunamei) is commonly used in the New Testament to denote some miraculous and extraordinary power; and here it evidently means that the Lord Jesus would exert such a power in the infliction of pain and for the preservation of the purity of his church.
