John Chrysostom
Here the Apostle commands not only that the imposed punishment be released, but also raises the guilty man to his former state.
For if someone punishes the guilty and simply lets him go without any consolation, he does him no good.
But see again how the Apostle restrains the guilty man, lest, after receiving forgiveness, he become worse.
He shows him that although he confessed his sin and repented of it, nevertheless he receives forgiveness not so much for repentance as by mercy and condescension.
Therefore he says, "so that you should rather forgive and comfort him."
This is also evident from the words that follow. "I permit you to forgive the guilty man," he says, "not because he is worthy of this, or because he has shown sufficient repentance, but because he is weak."

Therefore he added, "lest he be swallowed up by excessive sorrow."
By speaking so, the Apostle both testifies to the guilty man's great repentance and does not allow him to reach despair.
What does "lest he be swallowed up" mean? Either that he might act like Judas, or that, while remaining alive, he might become still worse.
"Although," he says, "he is not such that he cannot bear the sorrow of prolonged punishment, still, losing patience and hope, he could easily lay hands on his own life.
Or in the end he could give himself over to greater impiety.
Therefore we must be watchful, lest the wound become more serious and lest by excess in punishment we destroy what we have already done well."
By saying this, as I have already noted, the Apostle wished both to restrain and to instruct the guilty man.
He did this so that, after receiving forgiveness, he would not become still more negligent.
"I received him," he says, "into my former disposition not because he had been completely cleansed from defilement, but because I feared lest he do something worse."
From this we learn that the measure of repentance must be appointed not only according to the nature of sins, but also according to the disposition and condition of the sinners themselves.
So the Apostle acted then, since he too was frightened by the sinner's weakness.
Therefore he said, "lest he be swallowed up," as though by some beast, or by waves, or by a storm.
