Matthew 18:32

Clement of Alexandria Stromata Book I

But to him who had hid the money, entrusted to him to be given out at interest, and had given it back as he had received it, without increase, He said, "Thou wicked and slothful servant, thou oughtest to have given my money to the bankers, and at my coming I should have received mine own." Wherefore the useless servant "shall be cast into outer darkness."[5]

Cyprian Epistle XXX

in the law of their very entreaty let consideration be had for the time; let it be with downcast entreaty, with subdued petition, since he also who is besought ought to be bent, not provoked; and as the divine clemency ought to be looked to, so also ought the divine censure; and as it is written, "I forgave thee all that debt, because thou desiredst me,"[18]

Cyprian Treatise IV On the Lord's Prayer " After the supply of food, pardon of sin is also asked for, that he who is fed by God may live in God, and that not only the present and temporal life may be provided for, but the eternal also, to which we may come if our sins are forgiven; and these the Lord calls debts, as He says in His Gospel, "I forgave thee all that debt, because thou desiredst me."[58]
