Matthew 18:33

And it is to be known, that we read no answer made by that servant to his lord; by which it is shown us, that in the day of judgment, and altogether after this life, all excusing of ourselves shall be out off,

Wherefore also He went on to say, "The Kingdom of Heaven is likened unto a certain king, which would take account of his servants. And when he had begun to reckon, one was brought unto him, which owed him ten thousand talents. But forasmuch as he had not to pay, he commanded him to be sold, and his wife, and his children, and all that he had." Then after this man had enjoyed the benefit of mercy, he went out, and "took by the throat his fellow-servant, which owed him an hundred pence;" and having by these doings moved his lord, he caused him to cast him again into prison, until he should pay off the whole. Seest thou how great the difference between sins against man and against God? As great as between ten thousand talents, and a hundred pence, or rather even much more. And this arises both from the difference of the persons, and the constant succession of our sins. For when a man looks at us, we stand off and shrink from sinning: but when God sees us every day, we do not forbear, but do and speak all things without fear. But not hereby alone, but also from the benefit and from the honor of which we have partaken, our sins become more grievous.

"For there was brought unto Him," it saith, "one which owed ten thousand talents, and when he had not to pay, He commanded him to be sold, and his wife, and his children." Wherefore, I pray thee? Not of cruelty, nor of inhumanity (for the loss came back again upon himself, for she too was a slave), but of unspeakable tenderness. For it is His purpose to alarm him by this threat, that He might bring him to supplication, not that he should be sold. For if He had done it for this intent, He would not have consented to his request, neither would He have granted the favor. Wherefore then did He not do this, nor forgive the debt before the account? Desiring to teach him, from how many obligations He is delivering him, that in this way at least he might become more mild towards his fellow servant. For even if when he had learnt the weight of his debt, and the greatness of the forgiveness, he continued taking his fellow-servant by the throat; if He had not disciplined him beforehand with such medicines, to what length of cruelty might he not have gone? What then saith the other? "Have patience with me, and I will pay thee all. And his Lord was moved with compassion, and loosed him, and forgave him the debt." Seest thou again surpassing benevolence? The servant asked only for delay and putting off the time, but He gave more than he asked, remission and forgiveness of the entire debt. For it had been his will to give it even from the first, but he did not desire the gift to be his only, but also to come of this man's entreaty, that he might not go away uncrowned. For that the whole was of him, although this other fell down to him and prayed, the motive of the forgiveness showed, for "moved with compassion" he forgave him. […]

It is one thing to give pardon to a brother when he seeks it, that he may live with us in social charity, as Joseph to his brethren; and another to a hostile foe, that we may wish him good, and if we can do him good, as David mourning for Saul. Allegorically; The servant here who owed the ten thousand talents, is the Jewish people bound to the Ten Commandments in the Law. These the Lord oft forgave their trespasses, when being in difficulties they besought His mercy; but when they were set free, they exacted the utmost with great severity from all their debtors; and of the gentile people which they hated, they required circumcision and the ceremonies of the Law; yea, the Prophets and Apostles they barbarously put to death. For all this the Lord gave them over into the hands of the Romans as to evil spirits, who should punish them with eternal tortures.

Should you not then have had compassion also on your fellow servant? As if to say: you received great things, and you are unwilling to bestow small ones? Even as I had compassion on you.
