Should not you also have had compassion on your fellow servant, even as I had pity on you?
Read Chapter 18
John Chrysostom
AD 407
See again the lord's gentleness. He pleads with him, and excuses himself, being on the point of revoking his gift; or rather, it was not he that revoked it, but the one who had received it. Wherefore He says, I forgave you all that debt, because you desired me; should not thou also have had compassion on your fellow-servant? For even if the thing does seem to you hard; yet should you have looked to the gain, which has been, which is to be. Even if the injunction be galling, you ought to consider the reward; neither that he has grieved you, but that you have provoked God, whom by mere prayer you have reconciled. But if even so it be a galling thing to you to become friends with him who has grieved you, to fall into hell is far more grievous; and if you had set this against that, then you would have known that to forgive is a much lighter thing.
And whereas, when he owed ten thousand talents, he called him not wicked, neither reproached him, but showed mercy on him; when he had become harsh to his fellow-servant, then he says, O thou wicked servant.
Let us hearken, the covetous, for even to us is the word spoken. Let us hearken also, the merciless, and the cruel, for not to others are we cruel, but to ourselves. When then you are minded to be revengeful, consider that against yourself are you revengeful, not against another; that you are binding up your own sins, not your neighbors. For as to you, whatsoever you may do to this man, you do as a man and in the present life, but God not so, but more mightily will He take vengeance on you, and with the vengeance hereafter.
