3 For though absent in body, I am present in spirit; and as if present, I have already pronounced judgment on the one who did such a thing.
4 When you are assembled in the name of the Lord Jesus and my spirit is present, with the power of our Lord Jesus,
5 you are to deliver this man to Satan for the destruction of the flesh, so that his spirit may be saved in the day of the Lord.
I generally just read this and think automatically that it refers to an excommunication. However I am considering this time how the church gathering has a power. Paul speaks of his spirit being present. Using both the power of The Lord Jesus and the presence of Paul’s spirit they are instructed to “deliver this man to Satan for the destruction of the flesh, so that his spirit might be saved”, this sounds more like the opposite of a healing. Not something that is familiar to churches today. But something is mentioned in Revelation
0 But I have this against you, that you tolerate that woman Jezebel, who calls herself a prophetess and is teaching and seducing my servants to practice sexual immorality and to eat food sacrificed to idols.
21 I gave her time to repent, but she refuses to repent of her sexual immorality.
22 Behold, I will throw her onto a sickbed, and those who commit adultery with her I will throw into great tribulation, unless they repent of her works,
23 and I will strike her children dead. And all the churches will know that I am he who searches mind and heart, and I will give to each of you according to your works.
24 But to the rest of you in Thyatira, who do not hold this teaching, who have not learned what some call the deep things of Satan, to you I say, I do not lay on you any other
Notice verse 22 “I will throw her on a sick bed” this is another person who boasts even teaches sexual immorality.
