Catena Aurea · Matthäusevangelium 18
Therefore is the kingdom of heaven 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, his lord commanded him to be sold, and his wife, and children, and all that he had, and payment to be made. The servant therefore fell down, and worshipped him, saying, Lord, have patience with me, and I will pay thee all. Then the lord of that servant was moved with compassion, and loosed him, and forgave him the debt. But the same servant went out, and found one of his fellow-servants, which owed him an hundred pence: and he laid hands on him, and took him by the throat, saying, Pay me that thou owest. And his fellowservant fell down at his feet, and besought him, saying, Have patience with me, and I will pay thee all. And he would not: but went and cast him into prison, till he should pay the debt. So when his fellowservants saw what was done, they were very sorry, and came and told unto their lord all that was done. Then his lord, after that he had called him, said unto him, O thou wicked servant, I forgave thee all that debt, because thou desiredst me: Shouldest not thou also have had compassion on thy fellowservant, even as I had pity on thee? And his lord was wroth, and delivered him to the tormentors, till he should pay all that was due unto him. So likewise shall my heavenly Father do also unto you, if ye from your hearts forgive not every one his brother their trespasses.
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.
