31 As regards your attempt to show that railing and murder, the use of the expression raca and adultery, the idle word and godlessness, are rewarded with the same punishment, I have already given you my reply, and will now briefly repeat it. You must either deny that you are a sinner if you are not to be in danger of Gehenna: or, if you are a sinner you will be sent to hell for even a light offense: “The mouth that lies,” says one, “kills the soul.” I suspect that you, like other men, have occasionally told a lie: for all men are liars, that God alone may be true, and that He may be justified in His words, and may prevail when He judges.
It follows either that you will not be a man lest you be found a liar: or if you are a man and are consequently a liar, you will be punished with parricides and adulterers. For you admit no difference between sins, and the gratitude of those whom you raise from the mire and set on high will not equal the rage against you of those whom for the trifling offenses of daily life you have thrust into utter darkness. And if it be so that in a persecution one is stifled, another beheaded, another flees, or the fourth dies within the walls of a prison, and one crown of victory awaits various kinds of struggle, the fact tells in our favour.
For in martyrdom it is the will, which gives occasion to the death, that is crowned. My duty is to resist the frenzy of the heathen, and not deny the Lord. It rests with them either to behead, or to burn, or to shut up in prison, or enforce various other penalties. But if I escape, and die in solitude, there will not at my death be the same crown for me as for them, because the confession of Christ will not have been to me as to them the cause of death. As for your remark that absolutely no difference was made between the brother who had always been with his father, and him who was afterwards welcomed as a penitent, I am willing to add, if you like, that the one drachma which was lost and was found was put with the others, and that the one sheep which the good shepherd, leaving the ninety and nine, sought and brought back, made up the full tale of a hundred.
But it is one thing to be a penitent, and with tears sue for pardon, another to be always with the father. And so both the shepherd and the father say by the mouth of Ezekiel to the sheep that was carried back, and to the son that was lost, “And I will establish my covenant with you; and you shall know that I am the Lord: that you may remember, and be confounded, and never open your mouth ever more, because of your shame, when I have forgiven you all that you have done.” That penitents may have their due it is enough for them to feel shame instead of all other punishment.
Hence in another place it is said to them, “Then shall you remember your evil ways, and all the crimes wherewith you were defiled, and you shall loathe yourselves in your own sight for all the wickedness that you have done; and you shall know that I am the Lord, when I shall have done you good for my name's sake, and not according to your evil ways, nor according to your evil doings.” The son, moreover, was reproved by his father for envying his brother's deliverance, and for being tormented by jealousy while the angels in heaven were rejoicing.
The parallel, however, is not to be drawn between the merits of the two sons (one of whom was temperate, the other a prodigal) and those of the whole human race, but the characters depicted are either Jews and Christians, or saints and penitents. In the lifetime of Bishop Damasus I dedicated to him a small treatise upon this parable.
