2 On this account I trust that there may be a good hope; for God will not disdain to look upon such earnestness and zeal, nor will He suffer his servant to return without success. I know that when he has barely seen our pious Emperor, and been seen by him, he will be able at once by his very countenance to allay his wrath. For not only the words of the saints, but their very countenances are full of grace. And he is a person too endowed with abundant wisdom; and being well skilled in the divine laws, he will say to him as Moses said to God, “Yet now, if you will forgive their sin—and if not, slay me together with them.” For such are the bowels of the saints, that they think death with their children sweeter than life without them.
He will also make the special season his advocate and shelter himself behind the sacred festival of the Passover; and will remind the Emperor of the season when Christ remitted the sins of the whole world. He will exhort him to imitate his Lord. He will also remind him of that parable of the ten thousand talents, and the hundred pence. I know the boldness of our father, that he will not hesitate to alarm him from the parable, and to say, “Take heed lest you also hear it said in that day, 'O thou wicked servant, I forgave you all that debt, because you desire me; you ought also to forgive your fellow-servants!' Thou dost to yourself a greater benefit than them, since by pardoning these few offenses you gain an amnesty for greater.”
To this address he will add that prayer, which those who initiated him into the sacred mystery taught him to offer up, and say, “Forgive us our debts, as we forgive our debtors.”
