The reading is from St. Paul's First Letter to the Corinthians 4:17-21; 5:1-5

Brethren, therefore I sent to you Timothy, my beloved and faithful child in Christ, as I teach them everywhere in every church. Some are arrogant, as though I were not coming to you. But I will come to you soon, if the Lord wills, and I will find out not the talk of these arrogant people but their power. For the kingdom of God does not consist in talk but in power. What do you wish? Shall I come to you with a rod, or with love in a spirit of gentleness? It is actually reported that there is immorality among you, and of a kind that is not found even among pagans; for a man is living with his father's wife. And you are arrogant! Ought you not rather to mourn? Let him who has done this be removed from among you. For though absent in body I am present in spirit, and as if present, I have already pronounced judgment in the name of the Lord Jesus on the man who has done such a thing. When you are assembled, and my spirit is present, with the power of our Lord Jesus, you are to deliver this man to Satan for the destruction of the flesh, that his spirit may be saved in the day of the Lord Jesus.
