Your glorying is not good. Know you not that a little leaven leavens the whole lump?
All Commentaries on 1 Corinthians 5:6 Go To 1 Corinthians 5
John Chrysostom
AD 407
Your glorying is not good: signifying that it was they up to the present time who had hindered him from repenting, by taking pride in him. Next he shows that he is taking this step in order to spare not that person only, but also those to whom he writes. To which effect he adds,
Do you not know, that a little leaven leavens the whole lump? For, says he, though the offense be his, yet if neglected it has power to waste the rest of the body of the Church also. For when the first transgressor escapes punishment, speedily will others also commit the same faults.
In these words he indicates moreover that their struggle and their danger is for the whole Church, not for any one person. For which purpose he needs also the similitude of the leaven. For as that, says he, though it be but little, transforms unto its own nature the whole lump; so also this man, if he be let go unpunished and this sin turn out unavenged, will corrupt likewise all the rest.
