XIX. But you have to live in the midst of public affairs, and are stained by them; and it would be a terrible thing to waste this mercy. The answer is simple. Flee, if you can, even from the forum, along with the good company, making yourself the wings of an eagle, or, to speak more suitably, of a dove...for what have you to do with Cæsar or the things of Cæsar?...until you can rest where there is no sin, and no blackening, and no biting snake in the way to hinder your godly steps. Snatch your soul away from the world; flee from Sodom; flee from the burning; travel on without turning back, lest you should be fixed as a pillar of salt. Escape to the Mountain lest you be destroyed with the plain. But if you are already bound and constrained by the chain of necessity, reason thus with yourself; or rather let me reason thus with you. It is better both to attain the good and to keep the purification. But if it be impossible to do both it is surely better to be a little stained with your public affairs than to fall altogether short of grace; just as I think it better to undergo a slight punishment from father or master than to be put out of doors; and to be a little beamed upon than to be left in total darkness. And it is the part of wise men to choose, as in good things the greater and more perfect, so in evils the lesser and lighter. Wherefore do not overmuch dread the purification. For our success is always judged by comparison with our place in life by our just and merciful Judge; and often one who is in public life and has had small success has had a greater reward than one who in the enjoyment of liberty has not completely succeeded; as I think it more marvellous for a man to advance a little in fetters, than for one to run who is not carrying any weight; or to be only a little spattered in walking through mud, than to be perfectly clean when the road is clean. To give you a proof of what I have said:— Rahab the harlot was justified by one thing alone, her hospitality, though she receives no praise for the rest of her conduct; and the Publican was exalted by one thing, his humility, though he received no testimony for anything else; so that you may learn not easily to despair concerning yourself.
XX. But some will say, What shall I gain, if, when I am preoccupied by baptism, and have cut off myself by my haste from the pleasures of life, when it was in my power to give the reins to pleasure, and then to obtain grace? For the labourers in the vineyard who had worked the longest time gained nothing thereby, for equal wages were given to the very last. You have delivered me from some trouble, whoever you are who say this, because you have at last with much difficulty told the secret of your delay; and though I cannot applaud your shiftiness, I do applaud your confession. But come hither and listen to the interpretation of the parable, that you may not be injured by Scripture for want of information. First of all, there is no question here of baptism, but of those who believe at different times and enter the good vineyard of the Church. For from the day and hour at which each believed, from that day and hour he is required to work. And then, although they who entered first contributed more to the measure of the labour yet they did not contribute more to the measure of the purpose; nay perhaps even more was due to the last in respect of this, though the statement may seem paradoxical. For the cause of their later entrance was their later call to the work of the vineyard. In all other respects let us see how different they are. The first did not believe or enter till they had agreed on their hire; but the others came forward to do the work without an agreement, which is a proof of greater faith. And the first were found to be of an envious and murmuring nature, but no such charge is brought against the others. And to the first, that which was given was wages, though they were worthless fellows; to the last it was the free gift. So that the first were convicted of folly, and with reason deprived of the greater reward. Let us see what would have happened to them if they had been late. Why, the equal pay, evidently. How then can they blame the employer as unjust because of their equality? For all these things take away the merit of their labour from the first, although they were at work first; and therefore it turns out that the distribution of equal pay was just, if you measure the good will against the labour.
XXI. But supposing that the Parable does sketch the power of the font according to your interpretation, what would prevent you, if you entered first, and bore the heat, from avoiding envy of the last, that by this very lovingkindness you might obtain more, and receive the reward, not as of grace but as of debt? And next, the workmen who receive the wages are those who have entered, not those who have missed, the vineyard; which last is like to be your case. So that if it were certain that you would obtain the Gift, though you are of such a mind, and maliciously keep back some of the labour, you might be forgiven for taking refuge in such arguments, and desiring to make unlawful gain out of the kindness of the master; though I might assure you that the very fact of being able to labour is a greater reward to any who is not altogether of a huckstering mind. But since there is a risk of your being altogether shut out of the vineyard through your bargaining, and losing the capital through stopping to pick up little gains, do let yourselves be persuaded by my words to forsake the false interpretations and contradictions, and to come forward without arguing to receive the Gift, lest you should be snatched away before you realize your hopes, and should find out that it was to your own loss that you devised these sophistries.
XXII. But then, you say, is not God merciful, and since He knows our thoughts and searches out our desires, will He not take the desire of Baptism instead of Baptism? You are speaking in riddles, if what you mean is that because of God's mercy the unenlightened is enlightened in His sight; and he is within the kingdom of heaven who merely desires to attain to it, but refrains from doing that which pertains to the kingdom. I will, however, speak out boldly my opinion on these matters; and I think that all other sensible men will range themselves on my side. Of those who have received the gift, some were altogether alien from God and from salvation, both addicted to all manner of sin, and desirous to be bad; others were semivicious, and in a kind of mean state between good and bad; others again, while they did that which was evil, yet did not approve their own action, just as men in a fever are not pleased with their own sickness. And others even before they were illuminated were worthy of praise; partly by nature, and partly by the care with which they prepared themselves for Baptism. These after their initiation became evidently better, and less liable to fall; in the one case with a view to procuring good, and in the other in order to preserve it. And among these, those who gave in to some evil are better than those who were altogether bad; and better still than those who yielded a little, are those who were more zealous, and broke up their fallow ground before Baptism; they have the advantage over the others of having already laboured; for the font does not do away with good deeds as it does with sins. But better even than these are they who are also cultivating the Gift, and are polishing themselves to the utmost possible beauty.
