Charles Ellicott Commentary 1 Corinthians 5:2

"And ye are puffed up, and did not rather mourn, that he that had done this deed might be taken away from among you." — 1 Corinthians 5:2 (ASV)

And you are puffed up.—Better, And are you puffed up? etc. We have instances of similar sentences beginning with “and,”Luke 10:29.

The Apostle cannot mean that they actually gloried in this act of sin. Rather, their temper of mind was of the kind he has already described in the earlier chapters: they were puffing themselves up, one against another, in party rivalry. This was instead of being united in common grief over this shared offense, a grief which would have led them as one body to remove from their midst the person who had committed this deed.
