For with what judgment you judge, you shall be judged: and with what measure you measure, it shall be measured to you again.
All Commentaries on Matthew 7:2 Go To Matthew 7
John Chrysostom
AD 407
That is, it is not the other, says Christ, that you condemn, but yourself, and you are making the judgment-seat dreadful to yourself, and the account strict. As then in the forgiveness of our sins the beginnings are from us, so also in this judgment, it is by ourselves that the measures of our condemnation are laid down. You see, we ought not to upbraid nor trample upon them, but to admonish; not to revile, but to advise; not to assail with pride, but to correct with tenderness. For not him, but yourself, do you give over to extreme vengeance, by not sparing him, when it may be needful to give sentence on his offenses.
Do you see, how these two commandments are both easy, and fraught with great blessings to the obedient, even as of evils on the other hand, to the regardless? For both he that forgives his neighbor, has freed himself first of the two from the grounds of complaint, and that without any labor; and he that with tenderness and indulgence inquires into other men's offenses, great is the allowance of pardon, which he has by his judgment laid up beforehand for himself.
What then! say you: if one commit fornication, may I not say that fornication is a bad thing, nor at all correct him that is playing the wanton? Nay, correct him, but not as a foe, nor as an adversary exacting a penalty, but as a physician providing medicines. For neither did Christ say, stay not him that is sinning, but judge not; that is, be not bitter in pronouncing sentence.
