1 Corinthians 5:3-8

And all the time you believe yourselves to have achieved something! Under the law such offenders were taken out of the city by the whole congregation and stoned without the gate. In our spiritual church of faith this type and example should have taught you for ever to reject from your midst the spirit that works this evil and the persons who do it. But this sin has not been hidden from me. Absent in body, I have been present in spirit, and in that spirit I have already, as in your presence, as in the midst of the whole congregation, searched out and judged and given over to the devil from which it springs this old leaven of fornication and hell, thereby abandoning it to the doom that is coming on all flesh. For God is judging the flesh.
