Adam Clarke on 2 Corinthians 2:11

Lest Satan should get an advantage - If the man who has given sufficient proof of the sincerity of his repentance be not restored, he may be overwhelmed with sorrow, and sink into despair; and then the discipline of the Church will be represented, not as emendatory, but as leading to destruction. Of this our enemies would most gladly avail themselves, as they wish to discredit this ministry; and there is always at hand a devil to suggest evil, and prompt men to do it; for in this respect we have thorough acquaintance with his devices. Let us therefore be careful to remove, both from Satan and his partisans, all those occasions which might turn to the disadvantage or disparagement of the Gospel of Christ.
