You have heard that it has been said, You shall love your neighbor, and hate your enemy.
All Commentaries on Matthew 5:43 Go To Matthew 5
John Chrysostom
AD 407
See how He has set the highest pinnacle on our good deeds. For this is why He teaches not only to endure a blow, but to offer the right cheek also; not only to add the cloak to the coat, but to travel also two miles with him who compels you to go one; in order that you might receive with all facility that which is much more than these. But what, one may say, is more than these? Not even to count as an enemy him who is doing these things: or rather even somewhat else more than this. For He said not, do not hate, but love; He said not, do not injure, but do good.
