Therefore judge nothing before the time, until the Lord comes, who both will bring to light the hidden things of darkness, and will make manifest the counsels of the hearts: and then shall every man have praise of God.
All Commentaries on 1 Corinthians 4:5 Go To 1 Corinthians 4
John Chrysostom
AD 407
Paul is not talking here about those sins that we all recognize and confess as such. Rather he is speaking about preferring one person before another and making invidious comparisons of moral behaviors. Only God, who knows all our secret doings, can judge that sort of thing with accuracy. Only he knows what is more and what is less worthy of punishment.
