24. But one sometimes comes to a case of this kind, that we are not interrogated where the person is who is sought, nor forced to betray him, if he is hidden in such manner, that he cannot easily be found unless betrayed: but we are asked, whether he be in such a place or not. If we know him to be there, by holding our peace we betray him, or even by saying that we will in no wise tell whether he be there or not: for from this the questioner gathers that he is there, as, if he were not, nothing else would be answered by him who would not lie nor betray a man, but only, that he is not there. So, by our either holding our peace, or saying such words, a man is betrayed, and he who seeks him hath but to enter in, if he have the power, and find him: whereas he might have been turned aside from finding him by our telling a lie. Wherefore if thou know not where he is, there is no cause for hiding the truth, but thou must confess that thou knowest not. But, if thou know where he is, whether he be in the place which is named in the question or elsewhere; thou must not say, when it is asked whether he be there or not, "I will not tell thee what thou askest," but thou must say, "I know where he is, but I will never show." For if, touching one place in particular thou answer not and profess that thou wilt not betray, it is just as if thou shouldest point to that same place with thy finger: for a sure suspicion is thereby excited. But if at the first thou confess that thou know where he is, but will not tell, haply the inquisitor may be diverted from that place, and begin now to ply thee that the place where he is may be betrayed. For which good faith and humanity whatever thou shall bravely bear, is judged to be not only not culpable, but even laudable; save only these things which if a man suffer he is said to suffer not bravely, but immodestly and foully. For this is the last description of lie, concerning which we must treat more diligently. c25. For first to be eschewed is that capital lie and far to be fled from, which is done in doctrine of religion; to which lie a man ought by no consideration to be induced. The second, that he should hurt some man unjustly: which is such that it profits no man and hurts some man. The third, which so profits one as to hurt another, but not in corporal defilement. The fourth, that which is done through only lust of lying and deceiving, which is an unmixed lie. The fifth, what is done with desire of pleasing by agreeableness in talk. All these being utterly eschewed and rejected, there follows a sixth sort which at once hurts nobody and helps somebody; as when, if a person's money is to be unjustly taken from him, one who knows where the money is, should say that he does not know, by whomsoever the question be put. The seventh, which hurts none and profits some: except if a judge interrogate: as when, not wishing to betray a man who is sought for to be put to death, one should lie; not only a just and innocent, but also a culprit; because it belongs to Christian discipline neither to despair of any man's amendment, nor to bar the way of repentance against any. Of which two sorts, which are wont to be attended with great controversy, we have sufficiently treated, and have shown what was our judgment; that by taking the consequences, which are honorably and bravely borne, these kinds also should be eschewed by brave and faithful and truthful men and women. The eighth sort of lie is that which hurts no man, and does good in the preserving somebody from corporal defilement, at least that defilement which we have mentioned above. For even to eat with unwashen hands the Jews thought defilement. Or if a person think this also a defilement, yet not such that a lie ought to be told to avoid it. But if the lie be such as to do an injury to any man, even though it screen a man from that uncleanness which all men abhor and detest; whether a lie of this kind may be told provided the injury done by the lie be such as consists not in that sort of uncleanness with which we are now concerned, is another question: for here the question is no longer about lying, but it is asked whether an injury ought to be done to any man, even otherwise than by a lie, that the said defilement may be warded off from another. Which I should by no means think: though the case proposed be the slightest wrongs, as that which I mentioned above, about a single measure of wheat; and though it be very embarrassing whether it be our duty not to do even such an injury to any man, if thereby another may be defended or screened from a lustful outrage upon his person. But, as I said, this is another question: at present let us go on with what we have taken in hand: whether a lie ought to be told, if even the inevitable condition be proposed that we either do this, or suffer the deed of lust or some execrable pollution; even though by lying we do no man harm. c26. Touching which matter, there will be some place open for consideration, if first the divine authorities which forbid a lie be diligently discussed: for if these give no place, we vainly seek a loophole; for we are bound to keep in every way the command of God, and the will of God in all that through keeping His command we may suffer, it is our duty with an even mind to follow: but if by some relaxation any outlet be allowed, in such a case we are not to decline a lie. The reason why the Divine Scriptures contain not only God's commands, but the life and character of the just, is this: that, if haply it be hidden in what way we are to take that which is enjoined, by the actions of the just it may be understood. With the exception, therefore, of those actions which one may refer to an allegorical significance, although none doubts that they really took place, as is the case with almost all the occurrences in the books of the Old Testament. For who can venture to affirm of any thing there, that it does not pertain to a figurative foretelling? Seeing the Apostle, speaking of the sons of Abraham, of whom of course it is most easily said that they were born and did live in the natural order of propagating the people, (for not monsters and prodigies were born, to lead the mind to some presignification,) nevertheless asserteth that they signify the two Testaments; 
and saith of that marvellous benefit which God bestowed upon His people Israel to rescue them out of the bondage in which they in Egypt were oppressed, and of the punishment which avenged their sin on their journey, that these things befell them in a figure: 
what actions wilt thou find, from which thou mayest set aside that rule, and take upon thee to affirm that they are not to be reduced to some figure? Excepting therefore these, the things which in the New Testament are done by the Saints, where there is a most evident commending of manners to our imitation, may avail as examples for the understanding of the Scriptures, which things are digested in the commands.
