And grieve not the holy Spirit of God, by whom you are sealed unto the day of redemption.
All Commentaries on Ephesians 4:30 Go To Ephesians 4
John Chrysostom
AD 407
This is a particularly awful and fearful saying. It reminds us of what he said to the Thessalonians: “Whoever disregards this disregards not man but God.” … If you say an arrogant word, if you strike your brother, you have not merely hurt him but have grieved the Spirit. He contrasts such arrogance with the benevolence of God in order to sharpen the admonition. .
