Let no one therefore say that a man must not be rebuked when he deviates from the right way, but that his return and perseverance must only be asked for from the Lord for him. Let no considerate and believing man say this. For if such an one is called according to the purpose, beyond all doubt God is co-working for good to him even in the fact of his being rebuked. But since he who rebukes is ignorant whether he is so called, let him do with love what he knows ought to be done; for he knows that such an one ought to be rebuked. God will show either mercy or judgment; mercy, indeed, if he who is rebuked is “made to differ” by the bestowal of grace from the mass of perdition, and is not found among the vessels of wrath which are completed for destruction, but among the vessels of mercy which God has prepared for glory; 3339 but judgment, if among the former he is condemned, and is not predestinated among the latter.
