Has someone offended thee? ( Saint John Chrysostom )

Has someone offended thee? Guard thy breast with the sign of the Cross; remember what took place on the Cross, and all will be extinguished. Think not of offenses only, but recall also whatever good thou hast received from the one who has offended thee, and at once thou shalt grow meek. Bring to mind the fear of God, and quickly thou shalt grow more temperate and calm. 

Train thyself not to offend another during offenses themselves, and then, when offended, thou wilt not feel grief. Think to thyself that he who is offending thee is in a frenzy and not in his right mind, and then thou wilt not be vexed at the offense.

Saint John Chrysostom
