[¶0] 30. Moreover, it was said to the Apostles that they should take nothing with them for their journey, but should live by the Gospel. And in a certain place too the Lord Himself signified why He said this, when He added, “The laborer is worthy of his hire:” where He sufficiently shows that this is permitted, not ordered; lest haply he who should do this, namely, that in this work of preaching the word he should take aught for the uses of this life from them to whom he preached, should think he was doing any thing unlawful. And yet that it may more laudably not be done is sufficiently proved in the Apostle Paul: who, while he said, “Let him that is taught in the word, communicate unto him, that teacheth in all things,” and showed in many places that this is wholesomely done by them to whom he preached the word, “Nevertheless,” saith he, “I have not used this power.” The Lord, therefore, when He spake those words, gave power, not bound men by a command. So in general, what in words we are not able to understand, in the actions of the Saints we gather how it is meet to be taken, which would easily be drawn to the other side, unless it were recalled by an example.

### Section 31

[¶2] 31. Thus then what is written, “The mouth that lieth, slayeth the soul;” of what mouth it speaketh, is the question. For in general when the Scripture speaks of the mouth, it signifies the very seat of our conception in the heart, where is approved and decreed whatever also by the voice, when we speak the truth, is uttered: so that he lieth with the heart who approveth a lie; yet that man may possibly not lie with the heart, who uttereth other than is in his mind, in such sort that he knows it to be for the sake of avoiding a greater evil that he admitteth an evil, disapproving withal both the one and the other. And they who assert this, say that thus also is to be understood that which is written, “He that speaketh the truth in his heart:” because always in the heart truth must be spoken; but not always in the mouth of the body, if any cause of avoiding a greater evil require that other than is in the mind be uttered with the voice. And that there is indeed a mouth of the heart, may be understood even from this, that where there is speech, there a mouth is with no absurdity understood: nor would it be right to say, “Who speaketh in his heart,” unless it were right to understand that there is also a mouth in the heart. Though in that very place where it is written, “The mouth that lieth, slayeth the soul,” if the context of the lesson be considered, it may peradventure be taken for no other than the mouth of the heart. For there is an obscure response there, where it is hidden from men, to whom the mouth of the heart, unless the mouth of the body sound therewith, is not audible. But that mouth, the Scripture in that place saith, doth reach to the hearing of the Spirit of the Lord, Who hath filled the whole earth; at the same time mentioning lips and voice and tongue in that place; yet all these the sense permitteth not to be taken, but concerning the heart, because it saith of the Lord, that what is spoken is not hidden from Him: now that which is spoken with that sound which reacheth to our ears, is not hidden from men either. Thus, namely, is it written: “The Spirit of wisdom is loving, and will not acquit an evil-speaker of his lips: for of his reins God is witness, and of his heart a true searcher, and of his tongue a hearer. For the Spirit of the Lord hath filled the whole earth, and that which containeth all things hath knowledge of the voice. Therefore he that speaketh unrighteous things cannot be hid: but neither shall the judgment when it punisheth pass by him. For in the thoughts of the ungodly shall there be interrogation; and the hearing of his words shall come from the Lord, to the punishment of his iniquities. For the ear of jealousy heareth all things, and the tumult of murmurings will not be hid. Therefore keep yourselves from murmuring, which profiteth nothing, and from backbiting refrain your tongue: because an obscure response will not go into the void. But the mouth that lieth, slayeth the soul.” It seems then to threaten them who think that to be obscure and secret, which they agitate and turn over in their heart. And this, it would show, is so clear to the ears of God, that it even calls it “tumult.”

### Section 32

[¶4] 32. Manifestly also in the Gospel we find the mouth of the heart: so that in one place the Lord is found to have mentioned the mouth both of the body and of the heart, where he saith, “Are ye also yet without understanding? Do ye not yet understand, that whatsoever entereth in at the mouth, goeth into the belly, and is cast out into the draught? but those things which proceed out of the mouth come forth from the heart, and they defile the man. For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies: these are the things which defile a man.” Here if thou understand but one mouth, that of the body, how wilt thou understand, “Those things which proceed out of the mouth, come forth from the heart;” since spitting also and vomiting proceed out of the mouth? Unless peradventure a man is but then defiled when he eateth aught unclean, but is defiled when he vomits it up. But if this be most absurd, it remains that we understand the mouth of the heart to have been expounded by the Lord, when He saith, “The things which proceed out of the mouth, come forth from the heart.” For being that theft also can be, and often is, perpetrated with silence of the bodily voice and mouth; one must be out of his mind so to understand it as then to account a person to be contaminated by the sin of theft, when he confesses or makes it known, but when he commits it and holds his peace, then to think him undefiled. But, in truth, if we refer what is said to the mouth of the heart, no sin whatever can be committed tacitly: for it is not committed unless it proceed from that mouth which is within.

### Section 33

[¶6] 33. But, like as it is asked of what mouth the Scripture saith, “The mouth that lieth, slayeth the soul,” so it may be asked, of what lie. For it seems to speak of that lie in particular, which consists in detraction. It says, “Keep yourselves from murmuring, which profiteth nothing, and from detraction refrain your tongue.” Now this detraction takes place through malevolence, when any man not only with mouth and voice of the body doth utter what he forgeth against any, but even without speaking wisheth him to be thought such; which is in truth to detract with the mouth of the heart; which thing, it saith, cannot be obscure and hidden from God.

### Section 34

[¶8] 34. For what is written in another place, “Wish not to use every lie;” they say is not of force for this, that a person is not to use any lie. Therefore, when one man shall say, that according to this testimony of Scripture we must to that degree hold every sort and kind of lie in detestation, that even if a man wish to lie, yea, though he lie not, the very wish is to be condemned; and to this sense interpreteth, that it is not said, Do not use every lie, but, “Do not wish to use every lie;” that one must not dare not only to tell, but not even to wish to tell, any lie whatever: saith another man, “Nay, in that it saith, Do not wish to use every lie, it willeth that from the mouth of the heart we exterminate and estrange lying: so that while from some lies we must abstain with the mouth of the body, as are those chiefly which pertain to doctrine of religion; from some, we are not to abstain with the mouth of the body, if reason of avoiding a greater evil require; but with the mouth of the heart we must abstain utterly from every lie.” Where it behoveth to be understood what is said, “Do not wish:” namely, the will itself is taken as it were the mouth of the heart, so that it concerneth not the mouth of the heart when in shunning a greater evil we lie unwillingly. There is also a third sense in which thou mayest so take this word, “not every,” that, except some lies, it giveth thee leave to lie. Like as if he should say, wish not to believe every man: he would not mean to advise that none should be believed; but that not all, some however, should be believed. And that which follows, “For assiduity thereof will not profit for good,” sounds as if, not lying, but assiduous lying, that is, the custom and love of lying, should seem to be that which he would prohibit. To which that person will assuredly slide down, who either shall think that every lie may be boldly used (for so he will shun not that even which is committed in the doctrine of piety and religion; than which what more abominably wicked thing canst thou easily find, not among all lies, but among all sins?) or to some lie (no matter how easy, how harmless,) shall accommodate the inclination of the will; so as to lie, not unwillingly for the sake of escaping a greater evil, but willingly and with liking. So, seeing there be three things which may be understood in this sentence, either “Every lie, not only tell thou not, but do not even wish to tell:” or, “Do not wish, but even unwillingly tell a lie when aught worse is to be avoided:” or, “Not every,” to wit, that except some lies, the rest are admitted: one of these is found to make for those who hold that one is never to lie, two for those who think that sometimes one may tell a lie. But yet what follows, “For assiduity thereof will not profit to good,” I know not whether it can countenance the first sentence of these three; except haply so, that while it is a precept for the perfect not only not to lie, but not even to wish; assiduity of lying is not permitted even to beginners. As if, namely, on laying down the rule at no time whatever not merely to lie but so much as to have a wish to lie, and this being gainsaid by examples, in regard that there are some lies which have been even approved by great authority, it should be rejoined that those indeed are lies of beginners, which have, in regard of this life, some kind of duty of mercy; and yet to that degree is every lie evil, and by perfect and spiritual minds in every way to be eschewed, that not even beginners are permitted to have assiduous custom thereof. For we have already spoken concerning the Egyptian midwives, that it is in respect of the promise of growth and proficiency to better things that they while lying are spoken of with approval: because it is some step towards loving the true and eternal saving of the soul, when a person doth mercifully for the saving of any man’s albeit mortal life even tell a lie.

### Section 35

[¶10] 35. Moreover what is written “Thou wilt destroy all that speak leasing:” one saith that no lie is here excepted, but all condemned. Another saith: Yea verily: but they who speak leasing from the heart, as we disputed above; for that man speaketh truth in his heart, who hateth the necessity of lying, which he understands as a penalty of the moral life. Another saith: All indeed will God destroy who speak leasing, but not all leasing: for there is some leasing which the Prophet was at that time insinuating, in which none is spared; that is, if refusing to confess each one his sins, he defend them rather, and will not do penance, so that not content to work iniquity, he must needs wish to be thought just, and succumb not to the medicine of confession: as the very distinction of the words may seem to intimate no other, “Thou hatest all that work iniquity;” but wilt not destroy them if upon repenting they speak the truth in confession, that by doing that truth they may come to the light; as is said in the Gospel according to John, “But be that doeth truth cometh unto the light. Thou wilt destroy all who” not only work what Thou hatest, but also “speak leasing;” in holding out before them false righteousness, and not confessing their sins in penitence.

### Section 36

[¶12] 36. For, concerning false witness, which is set down in the ten commands of the Law, it can indeed in no wise be contended that love of truth may at heart be preserved, and false witness brought forth to him unto whom the witness is borne. For, when it is said to God only, then it is only in the heart that the truth is to be embraced: but when it is said to man, then must we with the mouth also of the body bring forth truth, because man is not an inspector of the heart. But then, touching the witness itself, it is not unreasonably asked, to whom one is a witness? For not to whomsoever we speak unto are we witnesses, but to them to whom it is expedient and due that they by our means should come to know or believe the truth; as is a judge, that he may not err in judging; or he who is taught in doctrine of religion, that he may not err in faith, or by very authority of the teacher waver in doubt. But when the person who interrogates thee or wishes to know aught from thee seeks that which concerneth him not, or which is not expedient for him to know, he craveth not a witness, but a betrayer. Therefore if to him thou tell a lie, from false witness peradventure thou wilt be clear, but from a lie assuredly not. So then with this salvo, that to bear false witness is never lawful, the question is, whether it be lawful sometimes to tell a lie. Or if it be false witness to lie at all, it is to be seen whether it admit of compensation, to wit, that it be said for the sake of avoiding a greater sin: as that which is written, “Honor father and mother,” under stress of a preferable duty is disregarded; whence the paying of the last honors of sepulture to a father, is forbidden to that man who by the Lord Himself is called to preach the kingdom of God.

### Section 37

[¶14] 37. Likewise, touching that which is written, “A son which receiveth the word shall be far from destruction: but receiving, he receiveth it for himself, and no falsehood proceedeth out of his mouth:” some one may say, that what is here set down, “A son which receiveth the word,” is to be taken for no other than the word of God, which is truth. Therefore, “A son receiving the truth shall be far from destruction,” refers to that which is written, “Thou wilt destroy all that speak leasing.” But when it follows, “Receiving he receiveth for himself,” what other doth this insinuate than what the Apostle saith, “But let every man prove his own work, and then he shall have glorying in himself and not in another?” For he that receiveth the word, that is, truth, not for himself, but for men-pleasing, keepeth it not when he sees they can be pleased by a lie. But whoso receiveth it for himself, no falsehood proceedeth out of his mouth: because even when the way to please men is to lie, that man lieth not, who receiving the truth not thereby to please them but to please God, hath received it for himself. Therefore there is no reason why it should be said here He will destroy all who speak leasing, but not all leasing: because all lies, universally, are cut off in this saying, “And no falsehood proceedeth out of his mouth.” But another saith, it is to be so taken as the Apostle Paul took our Lord’s saying, “But I say unto you, Swear not at all.” For here also all swearing is cut off; but from the mouth of the heart, that it should never be done with approbation of the will, but through necessity of the weakness of another; that is, “from the evil” of another, when it shows that he cannot otherwise be got to believe what is said, unless faith be wrought by an oath; or, from that “evil” of our own, that while as yet involved in the skins of this mortality we are not able to show our heart: which thing were we able to do, of swearing there were no need. Though moreover in this whole sentence, if the saying, “A son receiving the word shall be far from destruction,” be said of none other than that Truth, by Whom all things were made, which remaineth ever incommutable; then, because the doctrine of Religion strives to bring men to the contemplation of this Truth, it may seem that the saying, “And no falsehood proceedeth out of his mouth,” is said to this purpose, that he speaketh no falsehood that pertaineth to doctrine. Which sort of lie is upon no compensation whatever to be gone into, and is utterly and before all to be eschewed. Or if the saying, “No falsehood,” is absurdly taken if it be not referred to every lie, the saying, “From his mouth,” should, as was argued above, be taken to mean the mouth of the heart, in the opinion of him who accounts that sometimes one may tell a lie.

### Section 38

[¶16] 38. Certain it is, albeit all this disputation go from side to side, some asserting that it is never right to lie, and to this effect reciting divine testimonies: others gainsaying, and even in the midst of the very words of the divine testimonies seeking place for a lie; yet no man can say, that he finds this either in example or in word of the Scriptures, that any lie should seem a thing to be loved, or not had in hatred; howbeit sometimes by telling a lie thou must do that thou hatest, that what is more greatly to be detested may be avoided. But then here it is that people err; they put the precious beneath the vile. For when thou hast granted that some evil is to be admitted, that another and more grievous may not be admitted; not by the rule of truth, but by his own cupidity and custom doth each measure the evil, accounting that to be the more grievous, which himself more greatly dreads, not which is in reality more greatly to be fled from. All this fault is engendered by perversity of loving. For being there are two lives of ours; the one eternal, which is promised of God; the other temporal, in which we now are: when a man shall have begun to love this temporal more than that eternal, for the sake of this which he loveth he thinks all things right to be done; and there are not any, in his estimation, more grievous sins than those which do injury to this life, and either take away from it any commodity unjustly and unlawfully, or by inflicting of death take it utterly away. And so thieves, and robbers, and ruffians, and torturers, and slayers, are more hated of them than lascivious, drunken, luxurious men, if these molest no man. For they do not understand or at all care, that these do wrong to God; not indeed to any inconvenience of Him, but to their own pernicious hurt; seeing they corrupt His gifts bestowed upon them, even His temporal gifts, and by their very corruptions turn away from eternal gifts: above all, if they have already begun to be the Temple of God; which to all Christians the Apostle saith thus: “Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? Whoso shall corrupt God’s temple, God will corrupt him. For the temple of God is holy: which temple are ye.”

### Section 39

[¶18] 39. And all these sins, truly, whether such whereby an injury is done to men in the comforts of this life, or whereby men corrupt themselves and hurt none against his will: all these sins, then, even though they seem to mean well by this temporal life to the procuring of any delight or profit, (for no man commits any of these things with any other purpose and end;) yet in regard of that life which is forever and ever, they do entangle and in all ways hinder. But there are some of these that hinder the doers only, others likewise those on whom they are done. For as to the things which people keep safe for the sake of utility to this life, when these are taken away by injurious persons, they alone sin and are hindered from eternal life who do this, not they to whom they do it. Therefore, even if a person consent to the taking of them from him, either that he may not do some evil, or that he may not in these very things suffer some greater inconvenience; not only does he not sin, but in the one case he acts bravely and laudably, in the other usefully and unblameably. But as to those things which are kept for the sake of sanctity and religion, when injurious persons wish to violate these, it is right, if the condition be proposed and the means given, to redeem them even by sins of lesser moment, yet not by wrongs to other men. And then do these things thenceforth cease to be sins, which are undertaken in order to the avoidance of greater sins. For as in things useful, for instance in pecuniary or any other corporal commodity, that is not called a loss which is parted with in order to a greater gain; so in things holy, that is not called sin which is admitted lest a worse be admitted. Or if that is called loss, which one foregoes that he may not forego more; let this also be called sin, while however the necessity of undertaking it in order to the eschewing of a greater is no more to be doubted, than that, in order to avoid a greater loss, it is right to suffer a smaller one.

### Section 40

[¶20] 40. Now the things which are to be kept safe for sanctity’s sake are these: pudicity of body, and chastity of soul, and verity of doctrine. Pudicity of body, without consent and permission of the soul, doth no man violate. For, whatever against our will and without our empowering the same is by greater force done upon our body, is no lewdness. Howbeit, of permitting there may be some reason, but of consenting, none. For we consent, when we approve and wish: but we permit even not willing, because of some greater turpitude to be eschewed. Consent, truly, to corporal lewdness violates also chastity of mind. For the mind’s chastity consists in a good will and sincere love, which is not corrupted, unless when we love and desire that which Truth teaches ought not to be loved and desired. We have therefore to guard the sincerity of love toward God and our neighbor; for in this is chastity of mind sanctified: and we must endeavor with all the strength in our power, and with pious supplication, that, when the pudicity of our body is sought to be violated, not even that outermost sense of the soul, which is entangled with the flesh, may be touched with any delight; but if it cannot this, at least the mind and thought in not consenting may have its chastity preserved entire. Now what we have to guard in chastity of mind, is, as pertaining to the love of our neighbor, innocence and benevolence; as pertaining to the love of God, piety. Innocence is that we hurt no man; benevolence, that we also do good to whom we can; piety, that we worship God. But as for verity of doctrine, of religion and piety, that is not violated unless by a lie; whereas the highest and inmost Verity Itself, Whose that doctrine is, can in no wise be violated: which Truth to attain unto, and in It on every wise to remain, and to It thoroughly to cleave, will not be permitted, but when this corruptible shall have put on incorruption, and this mortal shall have put on immortality. But, because all piety in this life is practice by which we tend to that life, which practice hath a guidance afforded unto it from that doctrine, which in human words and signs of corporal sacraments doth insinuate and intimate Truth herself: for this cause this also, which by lying is possible to be corrupted, is most of all to be kept incorrupt; that so, if aught in that chastity of mind be violated, it may have that wherefrom it may be repaired. For once corrupt authority of doctrine, and there can be none either course or recourse to chastity of mind.

### Section 41

[¶22] 41. There resulteth then from all these this sentence, that a lie which doth not violate the doctrine of piety, nor piety itself, nor innocence, nor benevolence, may on behalf of pudicity of body be admitted. And yet if any man should propose to himself so to love truth, not only that which consists in contemplation, but also in uttering the true thing, which each in its own kind of things is true, and no otherwise to bring forth with the mouth of the body his thought than in the mind it is conceived and beheld; so that he should prize the beauty of truth-telling honesty, not only above gold and silver and jewels and pleasant lands, but above this temporal life itself altogether and every good thing of the body, I know not whether any could wisely say that that man errs. And if he should prefer this and prize it more than all that himself hath of such things; rightly also would he prefer it to the temporal things of other men, whom by his innocence and benevolence he was bound to keep and to help. For he would love perfect faith, not only of believing aright those things which by an excellent authority and worthy of faith should to himself be spoken, but also of faithfully uttering what himself should judge right to be spoken, and should speak. For faith hath its name in the Latin tongue, from that the thing is done which is said: and thus it is manifest that one doth not exhibit when telling a lie. And even if this faith be less violated, when one lies in such sort that he is believed to no inconvenience and no pernicious hurt, with added intention moreover of guarding either one’s life or corporal purity; yet violated it is, and a thing is violated which ought to be kept safe in chastity and sanctity of mind. Whence we are constrained, not by opinion of men, which for the most part is in error, but by truth itself, truth which is eminent above all, and alone is most invincible, to prefer even to purity of body, perfect faith. For chastity of mind is, love well ordered, which does not place the greater below the smaller. Now it is less, whatever in the body than whatever in the mind can be violated. For assuredly when for corporal chasteness a man tells a lie, he sees indeed that his body is threatened with corruption, not from his own, but from another’s lust, but is cautious lest by permitting at least, he be a party. That permission, however, where is it but in the mind? So then, even corporal chasteness cannot be corrupted but in the mind; which not consenting nor permitting, it can by no means be rightly said that corporal chasteness is violated whatever in the body be perpetrated by another’s lust. Whence it is gathered, that much more must the chastity of the mind be preserved in the mind, in the which is the guardianship of the pudicity of the body. Wherefore, what in us lies, both the one and the other must by holy manners and conversation be walled and hedged round, lest from another quarter it be violated. But when both cannot be, which is to be slighted in comparison of which, who doth not see? when he seeth which to which is to be preferred, the mind to the body, or the body to the mind; and which is more to be shunned among sins, the permitting of another’s deed, or the committing of the deed thyself.

### Section 42

[¶24] 42. It clearly appears then, all being discussed, that those testimonies of Scripture have none other meaning than that we must never at all tell a lie: seeing that not any examples of lies, worthy of imitation, are found in the manners and actions of the Saints, as regards those Scriptures which are referred to no figurative signification, such as is the history in the Acts of the Apostles. For all those sayings of our Lord in the Gospel, which to more ignorant minds seem lies, are figurative significations. And as to what the Apostle says: “I am made all things to all men, that I might gain all;” the right understanding is, that he did this not by lying, but by sympathy; so that he dealt with them in liberating them with so great charity, as if he were himself in that evil from which he wished to make them whole. There must therefore be no lying in the doctrine of piety: it is a heinous wickedness, and the first sort of detestable lie. There must be no lying of the second sort; because no man must have a wrong done to him. There must be no lying of the third sort; because we are not to consult any man’s good to the injury of another. There must be no lying of the fourth sort, that is, for the lust of lying, which of itself is vicious. There must be no lying of the fifth sort, because not even the truth itself is to be uttered with the aim of men-pleasing, how much less a lie, which of itself, as a lie, is a foul thing? There must be no lying of the sixth sort; for it is not right that even the truth of testimony be corrupted for any man’s temporal convenience and safety. But unto eternal salvation none is to be led by aid of a lie. For not by the ill manners of them that convert him is he to be converted to good manners: because if it is meet to be done towards him, himself also ought when converted to do it toward others; and so is he converted not to good, but to ill manners, seeing that is held out to be imitated by him when converted, which was done unto him in converting him. Neither in the seventh sort must there be any lying; for it is meet that not any man’s commodity or temporal welfare be preferred to the perfecting of faith. Not even if any man is so ill moved by our right deeds as to become worse in his mind, and far more remote from piety, are right deeds therefore to be foregone: since what we are chiefly to hold is that whereunto we ought to call and invite them whom as our own selves we love; and with most courageous mind we must drink in that apostolic sentence: “To some we are a savor of life unto life, to others a savor of death unto death; and who is sufficient for these things?” Nor in the eighth sort must there be lying: because both among good things chastity of mind is greater than pudicity of body; and among evil things, that which ourselves do, than that which we suffer to be done. In these eight kinds, however, a man sins less when he tells a lie, in proportion as he emerges to the eighth: more, in proportion as he diverges to the first. But whoso shall think there is any sort of lie that is not sin, will deceive himself foully, while he deems himself honest as a deceiver of other men.
