For if we would judge ourselves, we should not be judged.
All Commentaries on 1 Corinthians 11:31 Go To 1 Corinthians 11
Augustine of Hippo
AD 430
Indeed, many sins seem to be ignored and go unpunished. But their punishment is reserved for the future. It is not in vain that the day when the Judge of the living and the dead shall come is rightly called the day of judgment. Just so, on the other hand, some sins are punished here, and if they are forgiven will certainly bring no harm upon us in the future age. Hence, referring to certain temporal punishments which are visited upon sinners in this life, the apostle, speaking to those whose sins are blotted out and not reserved to the end says: “But if we judged ourselves truly we should not be judged. But when we are judged by the Lord, we are chastened so that we may not be condemned along with the world.”
