To the Honourable Publicola, My Much Beloved Son, Augustine Sends Greeting in the Lord.

1. Your perplexities have, since I learned them by your letter, become mine also, not because all those things by which you tell me that you are disturbed, disturb my mind: but I have been much perplexed, I confess, by the question how your perplexities were to be removed; especially since you require me to give a conclusive answer, lest you should fall into greater doubts than you had before you applied to me to have them resolved. For I see that I cannot give this, since, though I may write things which appear to me most certain, if I do not convince you, you must be beyond question more at a loss than before; and though it is in my power to use arguments which weigh with myself, I may fail of convincing another by these. However, lest I should refuse the small service which your love claims, I have resolved after some consideration to write in reply.

2. One of your doubts is as to using the services of a man who has guaranteed his fidelity by swearing by his false gods. In this matter I beg you to consider whether, in the event of a man failing to keep his word after having pledged himself by such an oath, you would not regard him as guilty of a twofold sin. For if he kept the engagement which he had confirmed by this oath, he would be pronounced guilty in this only, that he swore by such deities; but no one would justly blame him for keeping his engagement. But in the case supposed, seeing that he both swore by those whom he should not worship, and did, notwithstanding his promise, what he should not have done, he was guilty of two sins: whence it is obvious that in using, not for an evil work, but for some good and lawful end, the service of a man whose fidelity is known to have been confirmed by an oath in the name of false gods, one participates, not in the sin of swearing by the false gods, but in the good faith with which he keeps his promise. The faith which I here speak of as kept is not that on account of which those who are baptized in Christ are called faithful: that is entirely different and far removed from the faith desiderated in regard to the arrangements and compacts of men. Nevertheless it is, beyond all doubt, worse to swear falsely by the true God than to swear truly by the false gods; for the greater the holiness of that by which we swear, the greater is the sin of perjury. It is therefore a different question whether he is not guilty who requires another to pledge himself by taking an oath in the name of his gods, seeing that he worships false gods. In answering this question, we may accept as decisive those examples which you yourself quoted of Laban and of Abimelech (if Abimelech did swear by his gods, as Laban swore by the god of Nahor). This is, as I have said, another question, and one which would perchance perplex me, were it not for those examples of Isaac and Jacob, to which, for anything I know, others might be added. It may be that some scruple might yet be suggested by the precept in the New Testament, Swear not at all; Matthew 5:34, 36 words which were in my opinion spoken, not because it is a sin to swear a true oath, but because it is a heinous sin to forswear oneself: from which crime our Lord would have us keep at a great distance, when He charged us not to swear at all. I know, however, that our opinion is different: wherefore it should not be discussed at present; let us rather treat of that about which you have thought of asking my advice. On the same ground on which you forbear from swearing yourself, you may, if such be your opinion, regard it as forbidden to exact an oath from another, although it is expressly said, Swear not; but I do not remember reading anywhere in Holy Scripture that we are not to take another's oath. The question whether we ought to take advantage of the concord which is established between other parties by their exchange of oaths is entirely different. If we answer this in the negative, I know not whether we could find any place on earth in which we could live. For not only on the frontier, but throughout all the provinces, the security of peace rests on the oaths of barbarians. And from this it would follow, that not only the crops which are guarded by men who have sworn fidelity in the name of their false gods, but all things which enjoy the protection secured by the peace which a similar oath has ratified, are defiled. If this be admitted by you to be a complete absurdity, dismiss with it your doubts on the cases which you named.

3. Again, if from the threshing-floor or wine-press of a Christian anything be taken, with his knowledge, to be offered to false gods, he is guilty in permitting this to be done, if it be in his power to prevent it. If he finds that it has been done, or has not the power to prevent it, he uses without scruple the rest of the grain or wine, as uncontaminated, just as we use fountains from which we know that water has been taken to be used in idol-worship. The same principle decides the question about baths. For we have no scruple about inhaling the air into which we know that the smoke from all the altars and incense of idolaters ascends. From which it is manifest, that the thing forbidden is our devoting anything to the honour of the false gods, or appearing to do this by so acting as to encourage in such worship those who do not know our mind, although in our heart we despise their idols. And when temples, idols, groves, etc., are thrown down by permission from the authorities, although our taking part in this work is a clear proof of our not honouring, but rather abhorring, these things, we must nevertheless forbear from appropriating any of them to our own personal and private use; so that it may be manifest that in overthrowing these we are influenced, not by greed, but by piety. When, however, the spoils of these places are applied to the benefit of the community or devoted to the service of God, they are dealt with in the same manner as the men themselves when they are turned from impiety and sacrilege to the true religion. We understand this to be the will of God from the examples quoted by yourself: the grove of the false gods from which He commanded wood to be taken [by Gideon] for the burnt-offering; and Jericho, of which all the gold, silver, and brass was to be brought into the Lord's treasury. Hence also the precept in Deuteronomy: You shall not desire the silver or gold that is on them, nor take it unto you, lest you be snared therein; for it is an abomination to the Lord your God. Neither shall you bring an abomination into your house, lest you become a cursed thing like it: but you shall utterly detest it, and you shall utterly abhor it; for it is a cursed thing. Deuteronomy 7:25-26 From which it appears plainly, that either the appropriation of such spoils to their own private use was absolutely forbidden, or they were forbidden to carry anything of that kind into their own houses with the intention of giving to it honour; for then this would be an abomination and accursed in the sight of God; whereas the honour impiously given to such idols is, by their public destruction, utterly abolished.

4. As to meats offered to idols, I assure you we have no duty beyond observing what the apostle taught concerning them. Study, therefore, his words on the subject, which, if they were obscure to you, I would explain as well as I could. He does not sin who, unwittingly, afterwards partakes of food which he formerly refused because it had been offered to an idol. A kitchen-herb, or any other fruit of the ground, belongs to Him who created it; for the earth is the Lord's, and the fullness thereof, and every creature of God is good. But if that which the earth has borne is consecrated or offered to an idol, then we must reckon it among the things offered to idols. We must beware lest, in pronouncing that we ought not to eat the fruits of a garden belonging to an idol-temple, we be involved in the inference that it was wrong for the apostle to take food in Athens, since that city belonged to Minerva, and was consecrated to her as the guardian deity. The same answer I would give as to the well or fountain enclosed in a temple, though my scruples would be somewhat more awakened if some part of the sacrifices be thrown into the said well or fountain. But the case is, as I have said before, exactly parallel to our using of the air which receives the smoke of these sacrifices; or, if this be thought to make a difference, that the sacrifice, the smoke whereof mingles with the air, is not offered to the air itself, but to some idol or false god, whereas sometimes offerings are cast into the water with the intention of sacrificing to the waters themselves, it is enough to say that the same principle would preclude us from using the light of the sun, because wicked men continually worship that luminary wherever they are tolerated in doing so. Sacrifices are offered to the winds, which we nevertheless use for our convenience, although they seem, as it were, to inhale and swallow greedily the smoke of these sacrifices. If any one be in doubt regarding meat, whether it has been offered to an idol or not, and the fact be that it has not, when he eats that meat under the impression that it has not been offered to an idol, he by no means does wrong; because neither in fact, nor now in his judgment, is it food offered to an idol, although he formerly thought it was. For surely it is lawful to correct false impressions by others that are true. But if any one believes that to be good which is evil, and acts accordingly, he sins in entertaining that belief; and these are all sins of ignorance, in which one thinks that to be right which it is wrong for him to do.

5. As to killing others in order to defend one's own life, I do not approve of this, unless one happen to be a soldier or public functionary acting, not for himself, but in defense of others or of the city in which he resides, if he act according to the commission lawfully given him, and in the manner becoming his office. When, however, men are prevented, by being alarmed, from doing wrong, it may be said that a real service is done to themselves. The precept, Resist not evil, Matthew 5:39 was given to prevent us from taking pleasure in revenge, in which the mind is gratified by the sufferings of others, but not to make us neglect the duty of restraining men from sin. From this it follows that one is not guilty of homicide, because he has put up a wall round his estate, if any one is killed by the wall falling upon him when he is throwing it down. For a Christian is not guilty of homicide though his ox may gore or his horse kick a man, so that he dies. On such a principle, the oxen of a Christian should have no horns, and his horses no hoofs, and his dogs no teeth. On such a principle, when the Apostle Paul took care to inform the chief captain that an ambush was laid for him by certain desperadoes, and received in consequence an armed escort, Acts 23:17-24 if the villains who plotted his death had thrown themselves on the weapons of the soldiers, Paul would have had to acknowledge the shedding of their blood as a crime with which he was chargeable. God forbid that we should be blamed for accidents which, without our desire, happen to others through things done by us or found in our possession, which are in themselves good and lawful. In that event, we ought to have no iron implements for the house or the field, lest some one should by them lose his own life or take another's; no tree or rope on our premises, lest some one hang himself; no window in our house, lest some one throw himself down from it. But why mention more in a list which must be interminable? For what good and lawful thing is there in use among men which may not become chargeable with being an instrument of destruction?

6. I have now only to notice (unless I am mistaken) the case which you mentioned of a Christian on a journey overcome by the extremity of hunger; whether, if he could find nothing to eat but meat placed in an idol's temple, and there was no man near to relieve him, it would be better for him to die of starvation than to take that food for his nourishment? Since in this question it is not assumed that the food thus found was offered to the idol (for it might have been left by mistake or designedly by persons who, on a journey, had turned aside there to take refreshment; or it might have been put there for some other purpose), I answer briefly thus: Either it is certain that this food was offered to the idol, or it is certain that it was not, or neither of these things is known. If it is certain, it is better to reject it with Christian fortitude. In either of the other alternatives, it may be used for his necessity without any conscientious scruple.
