“If we would judge ourselves,” says the Apostle, “we would not be judged.” He did not say: if we punished ourselves and endured penalty for guilt (εί έκολάζομεν εαυτούς, εί έτιμαρούμεθα). He said only: if we were willing to acknowledge our sins, condemn ourselves, and confess our iniquities, then we would be freed from both the punishment here (καί τής ένταύθα) and the punishment to come (τιμωρίας).
For the one who condemns himself makes God merciful in two ways: by acknowledging his sins, and by becoming less inclined to sin in the future. Since we do not wish to do even this easy thing as it ought to be done, God does not wish to condemn us with the world. He spares us and punishes us here, where the punishment is temporary and the consolation is great.
For cleansing from sins is possible, and sweet hope remains, lightening the present. Therefore, wishing both to console the weak and to make others more zealous, the Apostle says: “But being judged, we are chastened by the Lord.”
He did not say: we are subjected to punishment (κολαζομεθα). He did not say: we are struck like criminals (τιμωρούμεθα). Rather, we are chastened as children (παιδευόμεθα). For this is more admonition than accusation, more remedy than punishment, and more correction than beating.
Here one may also recall the rule established at the Roman Council of the third century against the Novatians: Novatus and the others with him, who exalt themselves and have resolved to approve his brother-hating and inhuman opinion, are to be considered excommunicated from the Church. By contrast, the brethren who have unfortunately fallen are to be examined and healed by the means of repentance.
