And ye are puffed up - See the note at 1 Corinthians 4:18. You are filled with pride, and with a vain conceit of your own wisdom and purity, notwithstanding the existence of this enormous wickedness in your church. This does not mean that they were puffed up, or proud on account of the existence of this wickedness, but they were filled with pride notwithstanding, or in spite of it. They ought to have been a humbled people. They should have mourned; and should have given their first attention to the removal of the evil. But instead of this, they had given indulgence to proud feeling, and had become elated with a vain confidence in their spiritual purity. People are always elated and proud when they have the least occasion for it.
And have not rather mourned ... - Have not rather been so afflicted and troubled as to take the proper means for removing the offence. The word “mourn” here is taken in that large sense. Ye have not been “so much” afflicted - so troubled with the existence of this wickedness, as to take the proper measures to remove the offender - Acts of discipline in the church should always commence with mourning that there is occasion for it. It should not be anger, or pride, or revenge, or party feeling, which prompt to it. It should be deep grief that there is occasion for it; and tender compassion for the offender.
Might be taken away - By excommunication. He should not, while he continues in this state, be allowed to remain in your communion.
