Therefore all things whatsoever you would that men should do to you, do you even so to them: for this is the law and the prophets.
All Commentaries on Matthew 7:12 Go To Matthew 7
John Chrysostom
AD 407
In this statement Jesus briefly sums up all that is required. He shows that the definition of virtue is short and easy and known already to all. And he did not merely say, “Whatever things that you want,” but “Therefore whatever things that you want.” For he did not add this word therefore in its straightforward sense, but rather he used it with a deeper meaning. He is saying, “If you want to be heard, do these things in addition to those about which I have already spoken.” What are these additional things? “Whatever are those things that you want people to do to you.” Do you see how this shows that our wishes imply careful regulation of our behavior? Note that he did not say, “Whatever things that you want God to do for you, do these things to your neighbor.” Thus you cannot say, “How is that even possible? He is God and I am a human being!” Instead, Jesus said, “Whatever things that you want your fellow servant to do, you yourself also perform for your neighbor.” What is less of a burden than this? What is more just? Then the praise is exceedingly great: “For this is the law and the prophets.” From this it is clear that virtue is defined in accordance with our nature. So we all know within ourselves what our duties are. We cannot ever again find refuge in ignorance. The Gospel of Matthew, Homily
