Multa mihi legenda misisti, Consenti frater carissime, multa mihi legenda misisti. quibus rescripta dum praeparo et aliis atque aliis magis urgentibus occupationibus distrahor, emensus est annus atque in eas me detrusit angustias, ut quomodocumque rescriberem, ne arridente iam tempore nauigandi perlatorem remeare cupientem diutius detinerem. itaque omnibus, quae mihi Leonas dei famulus abs te adtulit, et mox ut ea sumpsi et postea cum haec dictare iam uellem euolutis atque perlectis et quanta potui consideratione perpensis ualde sum tuo delectatus eloquio et sanctarum memoria scripturarum ingeniique sollertia et dolore, quo neglegentes catholicos mordes, et zelo, quo aduersus etiam latentes haereticos frendes. sed non mihi persuadetur eos de latebris suis nostris esse mendaciis eruendos. ut quid enim eos tanta cura uestigare atque indagare conamur, nisi ut captos in apertumque productos aut etiam ipsos ueritatem doceamus aut certe ueritate conuictos nocere aliis non sinamus? ad hoc ergo, ut eorum mendacium deleatur siue caueatur, dei autem ueritas augeatur. quomodo igitur mendacio mendacia recte potero persequi? an et latrocinio latrocinia et sacrilegio sacrilegia et adulterio sunt adulteria persequenda? si autem ueritas dei in meo mendacio abundabit, numquidnam et nos dicturi sumus: faciamus mala, ut ueniant bona? quod uides quemadmodum detestetur apostolus. quid est enim aliud mentiamur, ut haereticos mendaces ad ueritatem adducamus, nisi: faciamus mala. ut ueniant bona? an aliquando bonum est mendacium uel aliquando mendacium non est malum? cur ergo scriptum est: odisti, domine, omnes, qui operantur iniquitatem; perdes omnes qui loquuntur mendacium? non enim aliquos excepit aut indefinite dixit (perdes loquentes mendacium, ut quosdam, non omnes intellegi sineret, sed uniuersalem sententiam protulit dicens: perdes omnes qui loquuntur mendacium. an quia non dictum est: perdes omnes qui loquuntur omne mendacium uel qui loquuntur quodcumque mendacium, ideo putandum est locum alicui relaxatum esse mendacio? ut scilicet sit aliquod mendacium, quod qui loquuntur non eos deus perdat, sed eos omnes perdat, qui loquuntur iniustum mendacium, non quodcumque mendacium, quia inuenitur et iustum, quod utique laudis debet esse, non criminis?

You have sent me much to read, dearest brother Consentius, you have sent me much to read. While I was preparing a reply to it, and was drawn away by one occupation after another more pressing, a year went by and pushed me into such straits that I had to reply in whatever way I could, so as not to detain any longer the bearer, who wished to return now that the sailing season was smiling. So, having unrolled and read through all that Leonas, the servant of God, brought me from you, both as soon as I received it and afterward, when I was ready to dictate this, and having weighed it with all the consideration I could, I was greatly delighted with your eloquence, your memory of the holy Scriptures, your skill of mind, the grief with which you sting careless catholics, and the zeal with which you gnash your teeth even against hidden heretics. But I am not persuaded that they should be dug out of their hiding places by our lies. For why do we try so carefully to track them and hunt them down, if not so that, once caught and brought out into the open, we may either teach them the truth too or at least, when they have been refuted by the truth, not allow them to harm others? For this purpose, then: that their lie may be destroyed or guarded against, and God's truth increased. How then can I rightly pursue lies by a lie? Are robberies also to be pursued by robbery, sacrileges by sacrilege, and adulteries by adultery? But if the truth of God will abound through my lie, are we too going to say, "Let us do evil that good may come"? You see how the apostle detests this. For what else is "Let us lie in order to bring lying heretics to the truth" but "Let us do evil that good may come"? Or is a lie sometimes good, or is a lie sometimes not evil? Why then is it written, "You hate, Lord, all who work iniquity; you will destroy all who speak a lie"? For he did not except some, nor did he speak indefinitely, "You will destroy those speaking a lie," so as to allow some, not all, to be understood, but he uttered a universal sentence, saying, "You will destroy all who speak a lie." Or, because it was not said, "You will destroy all who speak every lie" or "who speak any lie whatever," is it therefore to be thought that room has been left for some lie? So that, namely, there is some lie such that God does not destroy those who speak it, but destroys all those who speak an unjust lie, not any lie whatever, because a just lie is also found, which would certainly deserve praise, not blame?

2CSEL 41:471–472

Nonne cernis, quantum adiuuet haec disputatio eos ipsos, quos pro magna uenatione mendaciis nostris capere molimur? Priscillianistarum est enim, sicut ipse monstrasti, ista sententia: cui comprobandae adhibent testimonia de scripturis exhortantes suos ad mentiendum tamquam exemplis patriarcharum, prophetarum, apostolorum, angelorum, non dubitantes addere etiam ipsum dominum Christum nec se aliter arbitrantes ueracem suam ostendere falsitatem, nisi ueritatem dicant esse mendacem. redarguenda sunt ista, non imitanda; nec in eo malo debemus Priscillianistarum esse participes, in quo ceteris haereticis conuincuntur esse peiores. ipsi enim soli uel certe maxime ipsi reperiuntur ad occultandam suam quam putant ueritatem dogmatizare mendacium atque hoc tam magnum malum ideo iustum existimare, quia dicunt in corde retinendum esse, quod uerum est, ore autem ad alienos proferre falsum nullum esse peccatum et hoc esse scriptum: qui loquitur ueritatem in corde suo; tamquam hoc satis sit ad iustitiam, etiamsi loquatur quisque in ore mendacium, quando non proximus, sed alienus hoc audit. propterea etiam putant apostolum Paulum, cum dixisset: deponentes mendacium loquimini ueritatem, statim addidisse: unusquisque cum proximo suo, quia sumus inuicem membra, ut uidelicet cum eis, qui nobis in societate ueritatis proximi non sunt neque, ut ita dicam, commembres nostri sunt, loqui liceat oporteatque mendacium.

Do you not see how much this argument helps the very people we are striving to catch with our lies as a great prize of the hunt? For this is the view of the Priscillianists, as you yourself have shown. To prove it they bring testimonies from the Scriptures, urging their followers to lie as if by the examples of patriarchs, prophets, apostles, and angels, not hesitating to add even the Lord Christ himself, and not thinking they can show their falsehood to be truthful except by saying that the Truth is a liar. These things are to be refuted, not imitated; and we must not be partners of the Priscillianists in that evil in which they are shown to be worse than other heretics. For they alone, or at least they above all, are found to make lying a doctrine for concealing what they think is the truth, and to consider so great an evil just on the ground that, they say, what is true must be kept in the heart, but to utter what is false with the mouth to outsiders is no sin; and that this is what is written, "who speaks truth in his heart," as if this were enough for righteousness even if one speaks a lie with the mouth, when not a neighbor but an outsider hears it. For this reason they even think that the apostle Paul, when he had said, "Putting away lying, speak the truth," at once added, "each with his neighbor, for we are members of one another," so that it would be permitted, and indeed right, to speak a lie with those who are not our neighbors in the fellowship of the truth and are not, so to speak, our fellow members.

Notes and citation

Summary: The Priscillianists make lying a doctrine, twisting Ps 15:2 and Eph 4:25 to permit lies to outsiders, and catholics must not share this evil.

3CSEL 41:472–474

Quae sententia sanctos martyres exhonorat, immo uero aufert sancta omnino martyria. iustius enim sapientiusque facerent secundum istos, si persecutoribus suis non se confiterentur esse christianos nec eos sua confessione facerent homicidas, sed potius mentiendo et negando quod erant, et ipsi saluum haberent carnis commodum cordisque propositum et illos conceptum animo scelus inplere non sinerent. non enim proximi eorum erant in fide christiana, ut cum eis deberent loqui ueritatem in ore suo, quam loquebantur in corde suo, sed ipsius ueritatis insuper inimici. si enim Iehu, quem sibi inter ceteros ad exemplum mentiendi prudenter uidentur intueri, seruum Bahalis se esse mentitus est, ut seruos eius occideret, quanto iustius secundum istorum peruersitatem tempore persecutionis seruos daemonum se mentirentur serui Christi, ne serui daemonum seruos occiderent Christi, et sacrificarent idolis, ne interficerentur homines, si sacrificauit ille Bahali, ut interficeret homines? quid enim eis obesset secundum egregiam doctrinam mendaciloquorum, si diaboli cultum mentirentur in corpore, quando dei cultus seruabatur in corde? sed non sic intellexerunt apostolum martyres ueri, martyres sancti. uiderunt quippe tenueruntque quod dictum est: corde creditur ad iustitiam, ore confessio fit ad salutem, et: in ore eorum non est inuentum mendacium, ac sic inreprehensibiles abierunt, ubi temptari a mendacibus ulterius non cauebunt, quia mendaces amplius in suis caelestibus coetibus uel alienos uel proximos non habebunt. illum uero Iehu mendacio inpio et sacrificio sacrilego occidendos inpios et sacrilegos inquirentem non imitarentur, nec si de illo qualis fuisset eadem scriptura tacuisset. cum uero scriptum sit eum rectum cor non habuisse cum deo, quid ei profuit, quod pro nonnulla oboedientia, quam de domo Achab omnino delenda pro cupiditate suae dominationis exhibuit, aliquantam mercedem transitoriam regni temporalis accepit? ad sententiam potius ueridicam martyrum defendendam te, frater, exhortor, ut sis aduersus mendaces non mendacii doctor, sed ueritatis assertor. nam diligentius. obsecro, adtende, quod dico, ut inuenias quam sit cauendum. quod zelo quidem laudabili aduersus inpios, ut possint conprehendi et corrigi uel uitari, sed tamen incautius docendum putatur.

This view dishonors the holy martyrs; rather, it takes away holy martyrdoms altogether. For according to these people they would have acted more justly and wisely if they had not confessed to their persecutors that they were Christians, nor made them murderers by their confession, but rather by lying and denying what they were had both kept safe the advantage of the flesh and the resolve of the heart, and not allowed the persecutors to carry out the crime they had conceived in their minds. For the persecutors were not their neighbors in the Christian faith, so that they ought to speak with them in their mouth the truth that they spoke in their heart; they were, moreover, enemies of the truth itself. For if Jehu, whom they seem to themselves to look to shrewdly, among others, as an example of lying, lied that he was a servant of Baal in order to kill Baal's servants, how much more justly, according to their perversity, would the servants of Christ, in time of persecution, lie that they were servants of demons, so that the servants of demons would not kill the servants of Christ; and sacrifice to idols so that men would not be killed, if he sacrificed to Baal in order to kill men? For what would it harm them, according to the excellent teaching of the liars, if they feigned the worship of the devil in the body while the worship of God was kept in the heart? But the true martyrs, the holy martyrs, did not understand the apostle so. For they saw and held fast what was said: "With the heart one believes unto righteousness, with the mouth confession is made unto salvation," and, "In their mouth no lie was found"; and so they departed blameless to where they will no longer have to beware of being tempted by liars, because in their heavenly assemblies they will have no more liars, whether outsiders or neighbors. They would not imitate that Jehu, seeking out the ungodly and sacrilegious to be killed by an ungodly lie and a sacrilegious sacrifice, not even if the same Scripture had been silent about what kind of man he was. But since it is written that he did not have an upright heart with God, what did it profit him that, for some obedience which he showed in wholly destroying the house of Ahab, out of desire for his own dominion, he received some transitory reward of a temporal kingdom? Rather, brother, I urge you to defend the truthful view of the martyrs, so that against liars you may be not a teacher of lying but a champion of truth. For, I beg you, attend carefully to what I say, so that you may find how much that is to be guarded against which, with a zeal praiseworthy indeed against the ungodly, so that they may be caught and corrected or avoided, is nevertheless thought, too incautiously, to be something to teach.

Chapter 4

4CSEL 41:474–476

Mendaciorum genera multa sunt, quae quidem omnia uniuersaliter odisse debemus. nullum est enim mendacium, quod non sit contrarium ueritati. nam sicut lux et tenebrae, pietas et inpietas, iustitia et iniquitas, peccatum et recte factum, sanitas et inbecilitas, uita et mors, ita inter se sunt ueritas mendaciumque contraria. unde quanto amamus istam. tanto illud odisse debemus. uerumtamen sunt quaedam mendacia, quae credere nihil obsit, quamuis etiam tali mentiendi genere fallere uoluisse mentienti sit noxium, non credenti. tamquam si frater ille seruus dei Fronto in his, quae tibi indicauit — quod absit — aliqua mentiretur, sibi nocuisset profecto, non tibi, quamuis tu omnia credidisses sine tua iniquitate narranti, quoniam siue illa ita gesta sint siue non ita, non habent tamen aliquid, quod si quis crediderit ita esse gestum, etiamsi non ita sit gestum, regula ueritatis et doctrina salutis aeternae iudicetur esse culpandus. si autem hoc quisque mentiatur, quod si quis crediderit aduersus doctrinam Christi haereticus erit, tanto est nocentior mentiens, quanto miserior credens. uide ergo, quale sit, si aduersus doctrinam Christi mentiti fuerimus, quod quisquis crediderit interibit, ut inimicos eiusdem doctrinae capiamus, quos ad ueritatem, dum nos ab ea recedimus, adducamus, immo uero cum mendaces mentiendo capimus, mendacia peiora doceamus. aliud est enim quod dicunt, quando mentiuntur, aliud quando falluntur. nam cum haeresim suam docent, ea dicunt, in quibus falluntur; quando autem se dicunt sentire, quod non sentiunt, uel non sentire quod sentiunt, ea dicunt, in quibus mentiuntur. quod eis quisquis credit, etsi eos non inuenit, ipse non perit. a regula quippe catholica non recedit, qui haereticum catholica dogmata mendaciter profitentem catholicum credit. ac per hoc non est ei perniciosum, quia in hominis mente, de qua latente non potest iudicare, non in dei fallitur fide, quam debet insitam custodire. porro autem, quando haeresim suam docent, quisquis eis crediderit putando ueritatem, erit particeps ut erroris ita damnationis illorum. sic fit, ut, cum illi sua nefaria dogmata fabulantur, in quibus mortifero errore falluntur, tunc quisquis crediderit, pereat, nos autem quando catholica dogmata praedicamus, in quibus rectam fidem tenemus, tunc si crediderit, inueniatur quicumque perierat; quando uero, cum sint Priscillianistae, ut sua uenena non prodant, nostros se esse mentiuntur, quisquis nostrum eis credit etiam illis latentibus ipse catholicus perseuerat; nos contra ut ad eorum perueniamus indaginem, si Priscillianistas nos esse mentimur, quia eorum tamquam nostra sumus dogmata laudaturi, quisquis ea crediderit, aut confirmabitur apud eos aut transferetur ad eos interim statim. quid autem hora superuentura pariat, utrum inde postea liberentur uera dicentibus nobis, qui decepti sunt fallentibus nobis, et utrum audire uelint docentem, quem sic experti sunt mentientem, quis nouerit certum? quia hoc esse ignoret incertum? ex quo colligitur perniciosius aut, ut mitius loquar, periculosius mentiri catholicos, ut haereticos capiant, quam mentiuntur haeretici, ut catholicos lateant, quoniam quisquis credit catholicis mentiendo temptantibus, aut efficitur aut confirmatur haereticus, quisquis autem credit haereticis mentiendo sese occultantibus, non desinit esse catholicus. quod ut fiat planius, aliqua exempli gratia proponamus et ex eis potissimum scriptis, quae mihi legenda misisti.

There are many kinds of lies, all of which, indeed, we ought to hate universally. For there is no lie that is not contrary to truth. For just as light and darkness, godliness and ungodliness, righteousness and iniquity, sin and right action, health and weakness, life and death, so truth and lying are contrary to each other. Hence the more we love the one, the more we ought to hate the other. Yet there are some lies which it does no harm to believe, although even in that kind of lying the will to deceive harms the liar, not the believer. For example, if that brother Fronto, the servant of God, were lying in some of the things he reported to you (God forbid), he would certainly have harmed himself, not you, even if you had believed everything he told, without any wrong on your part, because, whether those things happened so or not, they contain nothing such that if someone believed it happened so, even if it did not, he would be judged blameworthy by the rule of truth and the teaching of eternal salvation. But if someone lies about something such that whoever believes it will be a heretic against the teaching of Christ, the liar is the more guilty as the believer is the more wretched. See, then, what it amounts to if we lie against the teaching of Christ, in a way that whoever believes it will perish, in order to catch the enemies of that teaching and bring them to the truth while we ourselves depart from it; or rather, when we catch liars by lying, we teach worse lies. For what they say when they lie is one thing, what they say when they are deceived is another. When they teach their heresy, they say the things in which they are deceived; but when they say that they hold what they do not hold, or do not hold what they hold, they say the things in which they lie. Whoever believes them in this, even if he does not find them out, does not himself perish. For one who believes a heretic to be a catholic, when he lyingly professes catholic doctrines, does not depart from the catholic rule. And so it is not ruinous to him, because he is deceived about a man's mind, which is hidden and about which he cannot judge, not about the faith of God, which he ought to guard as implanted in him. But when they teach their heresy, whoever believes them, thinking it the truth, will share both their error and their condemnation. So it comes about that when they tell their abominable doctrines, in which they are deceived by a deadly error, whoever believes perishes; but when we preach catholic doctrines, in which we hold the right faith, then whoever had perished is found, if he believes. When, however, being Priscillianists, they lie that they are ours, so as not to betray their poisons, whoever of ours believes them remains a catholic himself even though they are hidden. We, on the contrary, if in order to track them down we lie that we are Priscillianists, since we will praise their doctrines as our own, whoever believes them will either be confirmed among them or be carried over to them immediately in the meantime. But what the coming hour may bring forth, whether those who were deceived when we lied are afterward freed from there when we tell the truth, and whether they will be willing to listen to one teaching whom they have found lying in this way, who can know for certain? Who is unaware that this is uncertain? From this it is gathered that it is more ruinous, or, to speak more mildly, more dangerous, for catholics to lie in order to catch heretics than for heretics to lie in order to hide from catholics; for whoever believes catholics who test him by lying is either made or confirmed a heretic, whereas whoever believes heretics who conceal themselves by lying does not cease to be a catholic. To make this plainer, let us put forward some things by way of example, chiefly from the writings that you sent me to read.

Notes and citation

Summary: Lies differ in harm: believing a heretic who poses as a catholic harms no one's faith, but believing a catholic who poses as a heretic can make or confirm a heretic, so the catholic's lie is the more dangerous.

  • Fronto was a monk who had reported to Consentius his dealings with Priscillianists in Spain.

Ecce constituamus ante oculos callidum exploratorem accedere ad eum, quem Priscillianistam esse praesenserit, et Dictinii episcopi uel cogniti uitam uel incogniti famam laudare mendaciter; est hoc tolerabilius adhuc, quia ille putatur fuisse catholicus atque ex illo errore correctus. deinde Priscillianum — hoc enim sequitur in arte mentiendi — uenerabiliter commemoraturus est, hominem inpium et detestabilem et pro suis nefariis sceleribus criminibusque damnatum. in qua eius uenerabili commemoratione si forte ille, cui retia tenduntur huius modi, firmus Priscillianista non fuerat, hac eius praedicatione firmabitur. cum autem ad cetera explorantis sermo processerit et dicentis misereri se eorum, quos tantis errorum tenebris tenebrarum auctor inuoluerit, ut honorem animae suae et claritatem diuinae prosapiae non agnoscant, tum deinde Dictinii librum, cuius nomen est Libra, eo quod pertractatis duodecim quaestionibus uelut unciis explicatur, tantis extulerit laudibus, ut talem Libram, qua horrendae blasphemiae continentur, multis librarum auri milibus pretiosiorem esse testetur, nempe haec astutia mentientis animam credentis interficit aut iam interfectam in eadem morte demergit ac deprimit. sed, inquies, postea liberabitur. quid? si non fiat, siue aliquo interueniente inpedimento, ne coepta conpleantur, siue obstinatione mentis haereticae rursus eadem negantis, etiamsi aliqua iam coeperat confiteri? praesertim quia, si cognouerit se ab alieno fuisse temptatum, eo ipso audacius illa, quae sentit, studebit occultare mendacio, quando id inculpate fieri multo certius didicerit etiam ipsius sui temptatoris exemplo. hoc quippe in homine, quod ueritatem tegendam putat esse mentiendo, qua tandem fronte culpabimus et damnare audebimus, quod docemus?.

Look, let us set before our eyes a crafty spy approaching someone whom he has sensed to be a Priscillianist, and lyingly praising the life of Bishop Dictinius, if he knew him, or his reputation, if he did not. This is still more tolerable, because Dictinius is thought to have been a catholic and to have been corrected from that error. Then (for this follows in the art of lying) he will mention with veneration Priscillian, an ungodly and detestable man, condemned for his abominable wicked deeds and crimes. By this venerating mention, if the one for whom such nets are spread was perhaps not a firm Priscillianist, he will be made firm by this praise. And when the spy's talk has gone on to the rest, and he says that he pities those whom the author of darkness has wrapped in such darkness of errors that they do not recognize the honor of their soul and the glory of its divine lineage; and then extols with such praise the book of Dictinius called the Libra (the Pound), so named because it is set out in twelve questions, treated as if they were ounces, that he testifies that such a Pound, containing horrible blasphemies, is more precious than many thousands of pounds of gold: surely this cunning of the liar kills the soul of the one who believes, or, if it is already killed, sinks it and presses it down in the same death. "But," you will say, "afterward he will be set free." What if this does not happen, whether because some obstacle intervenes so that what was begun is not completed, or through the obstinacy of a heretical mind denying the same things again, even if it had already begun to confess some? Especially since, if he learns that he was tested by an outsider, he will for that very reason strive the more boldly to hide what he thinks by a lie, having learned far more surely, even from the example of his tempter himself, that this is done without blame. With what face, pray, shall we blame in a man, and dare to condemn, the fact that he thinks the truth is to be covered by lying, when we teach it?

Notes and citation

Summary: Augustine imagines a catholic spy praising Priscillian and Dictinius's book the Libra to trap a Priscillianist, showing that such lies confirm the heretic and teach him that lying is blameless.

  • Dictinius, bishop of Astorga, a Priscillianist who later renounced it; his Libra is lost. Twelve ounces made a Roman pound (libra).

Remanet igitur, ut, quod sentiunt Priscillianistae secundum haeresis suae nefariam falsitatem de deo, de anima. de corpore, de ceteris rebus, non dubitemus ueraci pietate damnare; quod autem sentiunt, ut ueritas occultetur, esse mentiendum, sit nobis et illis — quod absit — dogma commune. hoc tam magnum malum est, ut etiamsi conatus hic noster. quo eos per mendacium capere cupimus et mutare. ita prosperetur, ut eos capiamus atque mutemus, nullis lucris conpensentur haec damna, quibus et nos cum ipsis pro eorum correctione deprauamur. per hoc namque mendacium et nos erimus ex ea parte peruersi et ipsi semicorrecti, quandoquidem istuc, quod putant esse pro ueritate mentiendum, non in eis corrigimus, quia idem nos didicimus et docemus et fieri oportere praecipimus, ut ad eos emendandos peruenire possimus. quos tamen non emendamus, quibus mendum, quo uerum tegendum existimant, non auferimus, sed nos potius inmendamur, cum per tale mendum eos quaerimus nec inuenimus. quemadmodum eis conuersis credere ualeamus, quibus peruersis mentiti sumus, ne forte, quod ut caperentur sunt passi. faciant capti, non solum quia facere consuerunt, sed quia et in nobis, ad quos ueniunt, hoc inueniunt.

It remains, then, that what the Priscillianists hold, according to the abominable falsehood of their heresy, about God, the soul, the body, and other things, we should not hesitate to condemn with truthful godliness; but what they hold, that one must lie so that the truth may be hidden, is to be a doctrine common to us and them (God forbid!). This is so great an evil that even if this effort of ours, by which we wish to catch them through a lie and change them, should prosper so that we catch and change them, no gains would make up for these losses, by which we too are corrupted along with them for the sake of their correction. For through this lie we too will be perverted in that respect, and they only half corrected, since this very thing, that they think one must lie for the truth, we do not correct in them, because we have learned and teach the same thing and prescribe that it should be done, so that we may be able to reach them to amend them. Yet we do not amend them, since we do not remove from them the fault by which they think the truth should be covered, but rather we are made faulty ourselves, when we seek them through such a fault and do not find them. How shall we be able to believe them when converted, to whom we lied when they were perverse? Lest perhaps, having been caught, they do what they suffered in order to be caught, not only because they are accustomed to do it, but because they find it also in us, to whom they come.

Notes and citation

Summary: Lying to catch Priscillianists would make their chief error, that one may lie to hide the truth, a doctrine shared with catholics, corrupting both sides.

  • Augustine plays on emendare (amend) and mendum (fault) with his coinage inmendare, "to make faulty".

Chapter 7

7CSEL 41:479

Et quod est miserabilius, etiam ipsi iam quasi nostri effecti, quemadmodum nobis credant, reperire non possunt. si enim suspicentur etiam ipsa catholica dogmata nos mendaciter loqui, ut nescio quid aliud occultemus, quod uerum putamus, certe talia suspicanti dicturus es: hoc tunc ideo feci, ut caperem te. sed quid respondebis dicenti: unde igitur scio, utrum etiam nunc id facias, ne capiaris a me? an uero cuiquam persuaderi potest hominem non mentiri, ne capiatur qui mentitur, ut capiat? uidesne, quo tendat hoc malum? ut scilicet non solum nos illis ipsique nobis, sed omnis frater omni fratri non inmerito uideatur esse suspectus. atque ita, dum per mendacium tenditur, ut doceatur fides, id agitur potius, ut nulli habenda sit fides. si enim et contra deum loquimur, cum mentimur, quid tantum mali poterit in ullo mendacio reperiri, quod tamquam scelestissimum omni modo deuitare debeamus?

And what is more pitiable, even they, once made ours, as it were, cannot find how to believe us. For if they suspect that we speak even the catholic doctrines themselves lyingly, in order to hide something else that we think true, you will certainly say to one who suspects such things: "I did that then in order to catch you." But what will you answer him when he says, "How then do I know whether you are not doing it even now, so as not to be caught by me?" Or can anyone be persuaded that a man who lies in order to catch does not lie in order not to be caught? Do you see where this evil tends? Namely, that not only we to them and they to us, but every brother to every brother may, not without reason, seem suspect. And so, while through a lie the aim is that faith may be taught, what is achieved is rather that faith is to be placed in no one. For if we speak even against God when we lie, what evil so great can be found in any lie that we ought to avoid it in every way as most wicked?

Notes and citation

Summary: A catholic who lies to catch heretics can never be trusted by those he converts, and such lying makes every brother suspect to every brother.

Chapter 8

8CSEL 41:479–481

Sed nunc aduerte, quam tolerabilius Priscillianistae in nostra comparatione mentiantur, quando se fallaciter loqui sciunt, quos nostro mendacio liberandos putamus ab eis falsis, in quibus errando falluntur. Priscillianista dicit, quod anima sit pars dei et eiusdem cuius est ille naturae atque substantiae. magna haec est et detestanda blasphemia. sequitur enim, ut dei natura captiuetur, decipiatur, fallatur, conturbetur atque turpetur, damnetur atque crucietur. at si hoc et ille dicit, qui de tanto malo liberare cupit hominem per mendacium, uideamus, quid intersit inter utrumque blasphemum. plurimum inquis; nam hoc Priscillianista dicit ita etiam credens, catholicus autem non ita credens, quamuis ita loquens. ille ergo blasphemat nesciens, iste autem sciens; ille contra scientiam, iste contra conscientiam; ille habet caecitatem falsa sentiendi, sed in eis habet saltem uoluntatem uera dicendi; iste latens uidet uera et uolens loquitur falsa. sed ille, inquies, hoc docet, ut erroris sui faciat furorisque participes; iste autem hoc dicit, ut ab illo errore ac furore liberet homines. iam quidem supra ostendi, quantum et hoc noceat, quod creditur profuturum; uerum interim si appendamus in his duobus mala praesentia — quoniam futura bona, quae catholicus de corrigendo haeretico inquirit, incerta sunt — quis peccat grauius: utrum qui hominem decipit nesciens, an qui deum blasphemat sciens? profecto quid sit peius intellegit, qui homini deum sollicita pietate praeponit. huc accedit, quia. si blasphemandus est deus, ut ad eum laudandum homines adducamus, procul dubio non solum ad laudandum, uerum etiam ad blasphemandum deum exemplo et doctrina nostra homines inuitamus, quoniam quos ad dei laudes per dei blasphemias molimur adducere, utique si adduxerimus, non solum laudare discent, uerum etiam blasphemare. haec illis beneficia conferimus, quos non ignoranter, sed scienter blasphemando ab haereticis liberamus. et cum apostolus homines tradiderit etiam ipsi satanae, ut discerent non blasphemare, nos conamur homines eruere satanae, ut discant non per ignorantiam, sed per scientiam blasphemare, nobisque ipsis, magistris eorum, hoc tam magnum inportamus exitium, ut propter haereticos capiendos prius efficiamur, quod certum est, dei blasphematores, quo possimus propter eos, quod incertum est, liberandos ueritatis eius esse doctores?

But now notice how much more tolerably the Priscillianists lie compared with us, when they know that they are speaking deceitfully, those whom we think we should free by our lie from the falsehoods in which they are deceived by erring. The Priscillianist says that the soul is a part of God and of the same nature and substance as he. This is a great and detestable blasphemy. For it follows that the nature of God is taken captive, deceived, misled, disturbed and defiled, condemned and tormented. But if he too says this who wishes to free a man from so great an evil through a lie, let us see what difference there is between the two blasphemers. "A very great one," you say, "for the Priscillianist says this and also believes it, while the catholic does not believe it, although he says it." The one, then, blasphemes unknowingly, the other knowingly; the one against knowledge, the other against conscience; the one has the blindness of thinking false things, but in them he has at least the will to speak true things; the other, hidden, sees the truth and willingly speaks falsehood. "But the one," you will say, "teaches this in order to make people sharers in his error and madness, while the other says it in order to free people from that error and madness." I have already shown above how much harm is done even by what is believed to be going to profit. But meanwhile, if we weigh the present evils in these two (since the future goods that the catholic seeks from correcting the heretic are uncertain), who sins more gravely: the one who deceives a man unknowingly, or the one who blasphemes God knowingly? Surely he understands which is worse who with anxious godliness puts God before man. Add to this that if God is to be blasphemed so that we may bring men to praise him, then without doubt we invite men by our example and teaching not only to praise God but also to blaspheme him; for those whom we try to bring to the praises of God through blasphemies of God, if we do bring them, will learn not only to praise but also to blaspheme. These are the benefits we confer on those whom we free from the heretics by blaspheming, not ignorantly but knowingly. And whereas the apostle handed men over even to Satan himself so that they might learn not to blaspheme, we try to snatch men from Satan so that they may learn to blaspheme not through ignorance but through knowledge; and on ourselves, their teachers, we bring so great a ruin that, in order to catch heretics, we first become, which is certain, blasphemers of God, so that we may, which is uncertain, become teachers of his truth for the sake of freeing them?

9CSEL 41:481–482

Cum igitur blasphemare deum doceamus nostros, ut eos Priscillianistae credant suos, uideamus, quid mali dicant ipsi, quando propterea mentiuntur, ut eos nostros esse credamus. anathematizant Priscillianum et ad nostrum arbitrium detestantur; dicunt animam creaturam dei esse, non partem; exsecrantur Priscillianistarum falsa martyria; catholicos episcopos, a quibus illa haeresis nudata, oppugnata, prostrata est, magnis efferunt laudibus et cetera huius modi. ecce ipsi uera dicunt, quando mentiuntur, non quo simul possit hoc ipsum uerum esse, quod mendacium est, sed in alio quando mentiuntur, in alio uera dicunt; quando enim nostros se esse mentiuntur, de fide catholica uera dicunt. ac per hoc ipsi, ne Priscillianistae inueniantur, loquuntur mendaciter uera; nos autem, ut eos inueniamus, non solum mendaciter loquimur, ut ad illos pertinere credamur, sed etiam falsa loquimur, quae ad illorum errorem pertinere cognouimus. itaque illi quando nostri putari uolunt, et falsum est ex parte et uerum est ex parte, quod dicunt — falsum est enim eos nostros esse, uerum est autem animam partem dei non esse — nos uero quando ad eos pertinere putari uolumus, falsum est utrumque, quod dicimus, et Priscillianistas nos esse et animam partem dei esse. itaque illi deum laudant, non blasphemant, quando se occultant; et quando se non occultant, sed sua proferunt, blasphemare se nesciunt. ideo si ad fidem catholicam conuertantur, consolantur semet ipsos, quia possunt dicere, quod apostolus, qui cum inter cetera dixisset: prius fui blasphemus, misericordiam, inquit, consecutus sum, quia ignorans feci. nos contra, ut se nobis aperiant, si hoc quasi iustum mendacium fallendis eis capiendisque proferimus, profecto et ad blasphematores Priscillianistas pertinere nos dicimus et, ut nobis credant, sine excusatione ignorantiae blasphemamus. neque enim catholicus, qui blasphemando uult haereticus credi, potest dicere: ignorans feci.

Since, then, we would teach our people to blaspheme God so that the Priscillianists may believe them theirs, let us see what evil they themselves say when they lie so that we may believe them ours. They anathematize Priscillian and detest him to our satisfaction; they say that the soul is a creature of God, not a part of him; they curse the false martyrdoms of the Priscillianists; they extol with great praise the catholic bishops by whom that heresy was laid bare, attacked, and laid low; and other things of this kind. See, they speak the truth when they lie; not that the very same thing can at once be true and a lie, but they lie in one thing and speak truth in another; for when they lie that they are ours, they speak the truth about the catholic faith. And so they, in order not to be found out as Priscillianists, speak true things lyingly; but we, in order to find them, not only speak lyingly so as to be believed to belong to them, but also speak false things that we know belong to their error. So when they wish to be thought ours, what they say is partly false and partly true: it is false that they are ours, but true that the soul is not a part of God. But when we wish to be thought to belong to them, both things that we say are false: that we are Priscillianists and that the soul is a part of God. So they praise God, they do not blaspheme him, when they hide themselves; and when they do not hide themselves but bring out their own views, they do not know that they blaspheme. Therefore, if they are converted to the catholic faith, they console themselves, because they can say what the apostle said, who, having said among other things, "I was formerly a blasphemer," said, "I obtained mercy, because I did it ignorantly." We, on the contrary, if we utter this supposedly just lie to deceive and catch them, so that they may open themselves to us, certainly both say that we belong to the blaspheming Priscillianists and, so that they may believe us, blaspheme without the excuse of ignorance. For a catholic who wishes to be believed a heretic by blaspheming cannot say, "I did it ignorantly."

Semper, frater, in talibus causis cum timore recolendum est: quicumque me negauerit coram hominibus, negabo eum coram patre meo, qui in caelis est. an uero Christum coram hominibus non negat, qui eum coram Priscillianistis negat, ut eos latentes blasphemo mendacio nudet et capiat? quis autem dubitat, obsecro te, negari Christum, cum, sicuti est uerus, ita non esse dicitur et, sicut eum Priscillianista credit, ita esse dicitur?

Always, brother, in such cases we must recall with fear: "Whoever denies me before men, I will deny him before my Father who is in heaven." Or does he not deny Christ before men who denies him before Priscillianists in order to lay them bare and catch them in their hiding by a blasphemous lie? And who doubts, I beg you, that Christ is denied when he is said not to be as he truly is, and is said to be as the Priscillianist believes him to be?

Sed occultos lupos, inquies, indutos pellibus ouium et dominicum gregem latenter grauiterque uastantes aliter inuenire non possumus. unde ergo innotuerunt Priscillianistae, priusquam huius mendacii fuisset excogitata uenatio? unde ad ipsius auctoris illorum profecto astutioris et ideo tectioris cubile peruentum est? unde tot tantique manifestati atque damnati et ceteri innumerabiles partim correcti, partim uelut correcti et ecclesia miserante conlecti sunt? multas enim uias dat dominus, quando miseretur, quibus ad eorum perueniatur indaginem: quarum duae sunt aliis feliciores, ut uel ab eis, quos seducere uoluerunt, aut ab eis, quos iam seduxerant, resipiscentibus conuersisque monstrentur. quod facilius fit, si nefarius eorum error non mendacibus captationibus, sed ueracibus disputationibus euertatur. quibus conscribendis operam te oportet inpendere, quoniam dominus donauit, ut possis. quae scripta salubria, quibus eorum peruersitas insana destruitur, cum magis magisque innotuerint et a catholicis uel antistitibus, qui loquuntur in populis, uel a quibusque studiosis zelo dei plenis fuerint usquequaque diffusa, haec erunt sancta retia, quibus capiantur ueraciter, non mendaciter inquirantur. sic enim capti aut ultro quid fuerint fatebuntur et alios, quos in sua mala societate nouerunt, uel concorditer corrigent uel misericorditer prodent; aut, si eos pudebit fateri. quod diuturna simulatione texerunt, occulta dei manu medicante sanabuntur.

"But," you will say, "we cannot otherwise find the hidden wolves, clothed in sheep's skins, secretly and grievously ravaging the Lord's flock." How then did the Priscillianists become known before this hunt by lying was thought up? How was the lair of their author himself reached, who was surely more cunning and therefore better hidden? How were so many and such great ones exposed and condemned, and countless others partly corrected, partly corrected in appearance and gathered in by the church in its mercy? For the Lord, when he has mercy, gives many ways by which they may be tracked down; two of these are more fortunate than the others: that they be pointed out either by those whom they tried to seduce or by those whom they had already seduced, when these come to their senses and are converted. This happens more easily if their abominable error is overturned not by lying snares but by truthful arguments. You ought to spend your effort in writing these, since the Lord has given you the ability. When these wholesome writings, by which their insane perversity is destroyed, become better and better known, and are spread everywhere by catholic bishops who speak to the people or by any earnest people full of zeal for God, these will be the holy nets by which they may be caught truthfully, not searched out lyingly. For caught in this way they will either confess of their own accord what they were, and will either correct in agreement, or betray in mercy, others whom they know in their evil fellowship; or, if they are ashamed to confess what they have covered by long pretense, they will be healed by the hidden hand of God working the cure.

Matt 7:15 (allusion, high confidence)

Notes and citation

Summary: Hidden heretics can be found without lies, as the Priscillianists were before, chiefly through converts, and Consentius should write truthful refutations that will serve as holy nets.

12CSEL 41:484–485

Sed multo facilius, inquies, eorum latibula penetramus, si quod sunt nos esse mentiamur. hoc si liceret aut expediret, potuit Christus praecipere ouibus suis, ut lupinis amictae pellibus ad lupos uenirent et eos huius artis fallaciis inuenirent: quod eis non dixit nec quando eas in medium luporum se missurum esse praedixit. sed dices: non erant tunc inquirendi, cum essent apertissimi lupi, sed eorum morsus et saeuitia perferenda. quid? cum tempora posteriora praenuntians in uestitu ouium dixit rapaces lupos esse uenturos, nonne ibi erat locus, ut haec moneret et diceret: et uos, ut eos inueniatis, adsumite uestitum luporum, intrinsecus autem oues manete? non hoc ait. sed cum dixisset: multi ad uos uenient in uestitu ouium, intrinsecus autem sunt lupi rapaces, non addidit: ex mendaciis uestris. sed: ex fructibus eorum cognoscetis eos. ueritate sunt cauenda, ueritate capienda, ueritate occidenda mendacia. absit, ut blasphemias ignorantium scienter blasphemando uincamus, absit, ut mala fallacium imitando caueamus. quomodo enim cauebimus, si, ut caueamus, habebimus? si enim, ut capiatur qui blasphemat nesciens, blasphemabo sciens, peius est quod facio quam quod capio; si, ut inueniatur qui Christum negat nesciens, ego Christum negabo sciens, ad perditionem me secuturus est, quem sic inuenero: si quidem, ut illum inueniam, prior pereo.

"But," you will say, "we penetrate their lairs much more easily if we lie that we are what they are." If this were permitted or expedient, Christ could have instructed his sheep to come to the wolves clothed in wolves' skins and find them out by the deceits of this art. He did not say this to them, not even when he foretold that he would send them into the midst of wolves. But you will say: "At that time they did not need to be searched out, since the wolves were quite open; their bites and savagery had to be endured." What then? When, foretelling later times, he said that ravening wolves would come in sheep's clothing, was there not room there for him to give this warning and say: "And you, to find them, put on wolves' clothing, but remain sheep within"? He did not say this. But when he had said, "Many will come to you in sheep's clothing, but inwardly they are ravening wolves," he did not add, "By your lies," but, "By their fruits you will know them." By truth lies must be guarded against, by truth caught, by truth slain. Far be it from us to overcome the blasphemies of the ignorant by blaspheming knowingly; far be it from us to guard against the evils of deceivers by imitating them. For how shall we guard against them if, in order to guard against them, we shall have them? For if, in order that one who blasphemes unknowingly may be caught, I blaspheme knowingly, what I do is worse than what I catch; if, in order that one who denies Christ unknowingly may be found, I deny Christ knowingly, the one whom I find in this way will follow me to perdition, since, in order to find him, I perish first.

Chapter 13

13CSEL 41:485

An forte qui eo modo Priscillianistas inuenire molitur, ideo non negat Christum, quia ore depromit, quod corde non credit? quasi uero — quod et paulo ante iam dixi — cum dictum esset: corde creditur ad iustitiam, incassum est additum: ore confessio fit ad salutem. nonne paene omnes, qui Christum coram persecutoribus negauerunt, quod de illo credebant, corde tenuerunt et tamen ore ad salutem non confitendo perierunt, nisi qui paenitentia reuixerunt? quis ita uanescat, ut existimet apostolum Petrum hoc habuisse in corde quod in ore, quando Christum negauit? nempe in illa negatione intus ueritatem tenebat et foras mendacium proferebat. cur ergo lacrimis diluit, quod ore negauerat, si saluti sufficiebat, quod corde credebat? cur loquens in corde suo ueritatem tam amaro fletu puniuit mendacium, quod ore depromsit, nisi quia magnam uidit esse perniciem, quod corde quidem credidit ad iustitiam, sed ore non confessus est ad salutem?

Or perhaps one who strives to find Priscillianists in that way does not deny Christ, because he utters with the mouth what he does not believe in the heart? As if (as I have already said a little earlier), when it had been said, "With the heart one believes unto righteousness," it was added to no purpose, "With the mouth confession is made unto salvation." Did not almost all who denied Christ before persecutors hold in the heart what they believed about him, and yet, by not confessing with the mouth unto salvation, perish, except those who came back to life through repentance? Who is so empty-headed as to think that the apostle Peter had in his heart what he had in his mouth when he denied Christ? Surely in that denial he held the truth within and uttered a lie outwardly. Why then did he wash away with tears what he had denied with his mouth, if what he believed in his heart was enough for salvation? Why did he, speaking the truth in his heart, punish with such bitter weeping the lie that he uttered with his mouth, unless because he saw that it was a great ruin that he believed in his heart unto righteousness but did not confess with his mouth unto salvation?

Rom 10:10 (quotation, high confidence) · Matt 26:70 (allusion, high confidence) · Matt 26:75 (allusion, high confidence)

Notes and citation

Summary: Believing in the heart while denying with the mouth is not enough, as the lapsed in persecution and Peter's bitter tears after his denial show.

Quapropter illud, quod scriptum est: qui loquitur ueritatem in corde suo, non sic accipiendum est, quasi retenta in corde ueritate loquendum sit in ore mendacium. sed ideo dictum est, quia fieri potest, ut loquatur quisque ore ueritatem, quae nihil ei prosit, si eam in corde non teneat, id est, si quod loquitur ipse non credat. sicut haeretici, maximeque idem Priscillianistae faciunt, cum catholicam ueritatem non quidem credunt, sed tamen loquuntur, ut nostri esse credantur. loquuntur ergo ueritatem in ore suo, non in corde suo. propterea distinguendi erant ab illo, de quo dictum est: qui loquitur ueritatem in corde suo. hanc autem ueritatem catholicus sicut in corde loquitur, quia ita credit, ita et in ore debet, ut ita praedicet; contra istam uero nec in corde nec in ore habeat falsitatem, ut et corde credat ad iustitiam et ore confessionem faciat ad salutem. nam et in illo psalmo, cum dictum esset: qui loquitur ueritatem in corde suo, mox etiam hoc additum est: qui non egit dolum in lingua sua.

Therefore what is written, "who speaks truth in his heart," is not to be taken as if, keeping the truth in the heart, one should speak a lie with the mouth. It was said because it can happen that someone speaks the truth with his mouth and it profits him nothing if he does not hold it in his heart, that is, if he does not himself believe what he says; as heretics do, and especially these same Priscillianists, when they do not indeed believe the catholic truth, but still speak it so as to be believed to be ours. They speak the truth, then, in their mouth, not in their heart. That is why they had to be distinguished from the one of whom it was said, "who speaks truth in his heart." But this truth the catholic, just as he speaks it in his heart because he so believes, must also speak in his mouth, so that he so preaches it; and against it let him have falsehood neither in his heart nor in his mouth, so that he both believes with the heart unto righteousness and makes confession with the mouth unto salvation. For in that psalm too, when it had been said, "who speaks truth in his heart," this was also added at once: "who has not practiced deceit with his tongue."

Notes and citation

Summary: Ps 15:2 means that truth must be believed in the heart as well as spoken, not that lies are allowed on the tongue, as the next verse forbids deceit with the tongue.

Chapter 15

15CSEL 41:486–487

Et illud, quod ait apostolus: deponentes mendacium loquimini ueritatem unusquisque cum proximo suo. quia sumus inuicem membra, absit, ut sic intellegamus, tamquam loqui mendacium permiserit cum eis, qui nondum sunt nobiscum membra corporis Christi. sed ideo dictum est, quia unusquisque nostrum hoc debet quemque deputare, quod eum uult fieri, etiam si nondum factus est. sicut dominus alienigenam Samaritanum proximum eius ostendit, cum quo misericordiam fecit. proximus ergo habendus est, non alienus. cum quo id agendum est, ne remaneat alienus; et si propter id, quod nondum est, fidei nostrae sacramentique particeps factus, aliqua illi occultanda sunt uera, non tamen ideo dicenda sunt falsa.

And what the apostle says, "Putting away lying, speak the truth each with his neighbor, for we are members of one another": far be it from us to understand it as if he permitted us to speak a lie with those who are not yet members of the body of Christ with us. It was said because each of us ought to regard everyone as what he wishes him to become, even if he has not yet become it; just as the Lord showed that the Samaritan, a foreigner, was the neighbor of the one to whom he showed mercy. He is to be held, then, as a neighbor, not an outsider, with whom we must act so that he may not remain an outsider; and if, because he has not yet become a partaker of our faith and sacrament, some truths are to be concealed from him, still false things are not on that account to be said.

Eph 4:25 (quotation, high confidence) · Luke 10:36 (allusion, high confidence)

Notes and citation

Summary: Eph 4:25 does not permit lying to non-Christians, who are to be treated as neighbors; truths may sometimes be withheld from them, but falsehoods may not be told.

  • Eph 4:25; the Good Samaritan, Luke 10:29–37. The truths concealed from those not yet baptized are the sacraments kept from catechumens.

Chapter 16

16CSEL 41:487

Fuerunt enim etiam temporibus apostolorum, qui ueritatem non ueritate, id est non ueraci animo praedicarent: quos dicit apostolus Christum adnuntiasse non caste, sed per inuidiam et contentionem. ac per hoc etiam tunc nonnulli tolerati sunt adnuntiantes non casto animo ueritatem; non tamen ulli laudati sunt tamquam adnuntiantes casto animo falsitatem. denique de illis dicit: siue occasione siue ueritate Christus adnuntietur; nullo modo autem diceret, ut postea Christus adnuntietur, prius negetur.

For even in the times of the apostles there were those who preached the truth not in truth, that is, not with a truthful mind; of whom the apostle says that they proclaimed Christ not purely but through envy and rivalry. And so even then some were tolerated who proclaimed the truth with an impure mind; yet none were praised as proclaiming falsehood with a pure mind. Finally, he says of them, "Whether in pretense or in truth, let Christ be proclaimed"; but he would by no means say, "Let Christ first be denied, so that afterward he may be proclaimed."

Chapter 17

17CSEL 41:487–489

Quocirca multis quidem modis possunt latentes haeretici uestigari nec catholica fide uituperata nec haeretica inpietate laudata. Sed si aliter omnino non posset educi de cauernis suis haeretica inpietas, nisi a tramite ueritatis lingua catholica deuiaret, tolerabilius illa occultaretur, quam ista praecipitaretur; tolerabilius in suis foueis delitiscerent uulpes, quam propter illas capiendas in blasphemiae foueam caderent uenatores; tolerabilius perfidia Priscillianistarum ueritatis uelamine tegeretur, quam fides catholicorum. ne a Priscillianistis mentientibus laudaretur, a catholicis credentibus negaretur. nam si propterea iusta sunt non qualiacumque, sed blasphema mendacia, quia hoc animo fiunt, ut occulti haeretici detegantur poterunt isto modo, si eodem animo fiant, casta esse adulteria. quid? si enim ex numero Priscillianistarum inpudicarum aliqua femina iniciat oculum in catholicum Ioseph eique promittat prodituram se latebras eorum, si ab illo inpetrauerit stuprum, certumque sit eam, si ei consensum fuerit, quod pollicita est inpleturam, faciendumne censebimus? an intellegemus nequaquam tali pretio merces eius modi conparandas? cur ergo non emimus capiendos haereticos carne in adulterium. defluente et emendos putamus ore in blasphemia fornicante? aut enim licebit utrumque pari ratione defendere, ut ideo haec non esse dicantur iniusta, quia ea facta sunt intentione, qua conprehenderentur iniusti, aut, si sana doctrina nec propter inueniendos haereticos uult nos cum feminis inpudicis saltem corpore, non mente misceri, profecto nec propter inueniendos haereticos uult a nobis saltem uoce, non mente aut inmundam haeresim praedicari aut castam catholicam blasphemari, quia et ipsum mentis imperium, cui debet omnis inferior motus hominis oboedire, digno non carebit obprobrio, quando fit, quod fieri non oportet seu membro seu uerbo. quamquam etiam cum uerbo fit, membro fit, quoniam lingua membrum est, qua fit uerbum; nec ullum factum nostrum membro ullo paritur, nisi quod prius corde concipitur, uel potius intus cogitando et consentiendo iam partum foras editur faciendo per membrum. non itaque animus a facto excusatur, quando dicitur aliquid non ex animo fieri, quod tamen non fieret, nisi animus faciendum esse decerneret.

Therefore hidden heretics can be tracked down in many ways, without the catholic faith being reviled or heretical ungodliness praised. But if heretical ungodliness could not be brought out of its caves at all unless the catholic tongue strayed from the path of truth, it would be more tolerable for the former to be hidden than for the latter to be cast down headlong; more tolerable for the foxes to lurk in their holes than for the hunters, in order to catch them, to fall into the pit of blasphemy; more tolerable for the faithlessness of the Priscillianists to be covered with the veil of truth than for the faith of catholics, lest it be praised by lying Priscillianists, to be denied by believing catholics. For if lies, not of just any kind but blasphemous ones, are just because they are told with this intention, that hidden heretics may be uncovered, then in this way adulteries too could be chaste, if they were committed with the same intention. What then? If some woman from among the unchaste Priscillianist women should cast her eye on a catholic Joseph and promise him that she would betray their hiding places if she obtained sexual immorality from him, and it were certain that if he consented she would fulfil what she promised, shall we judge that it should be done? Or shall we understand that such wares are by no means to be bought at such a price? Why then do we not buy the capture of heretics with the flesh sliding into adultery, and yet think it should be bought with the mouth fornicating in blasphemy? For either it will be lawful to defend both on equal grounds, so that these things are said not to be unjust because they were done with the intention of catching the unjust; or, if sound doctrine does not want us, even for the sake of finding heretics, to have intercourse with unchaste women, even in body only and not in mind, then surely, even for the sake of finding heretics, it does not want us, even in voice only and not in mind, either to preach unclean heresy or to blaspheme the chaste catholic faith. For the very command of the mind, which every lower movement of a man ought to obey, will not escape due reproach when something is done that ought not to be done, whether by a member or by a word. And yet even when it is done by a word, it is done by a member, since the tongue, by which a word is made, is a member; and no deed of ours is brought forth by any member unless it is first conceived in the heart, or rather, already brought forth within by thinking and consenting, it is then put outside by doing it through a member. So the mind is not excused from a deed when something is said to be done not from the mind, which nevertheless would not be done unless the mind decided that it should be done.

Gen 39:7 (allusion, high confidence) · Gen 39:12 (allusion, medium confidence)

Notes and citation

Summary: If blasphemous lies were just when meant to expose heretics, adultery with the same aim would be chaste; since it is not, lying with the tongue for that purpose is not allowed either, for the mind directs every member.

  • Joseph and Potiphar's wife: Gen 39:7–12. Augustine uses stuprum (rendered "sexual immorality") and adulterium ("adultery") and the figure of the mouth "fornicating" in blasphemy.
