Matthew 7:16

Persons are still living who remember them,-their own actual disciples and successors,-who cannot therefore deny the lateness of their date. But, in fact, by their own works they are convicted, even as the Lord said. For since Marcion separated the New Testament from the Old, he is (necessarily) subsequent to that which he separated, inasmuch as it was only in his power to separate what was (previously) united.

Having taught that the gate is strait, because there are many that pervert the way that leads to it, He proceeds, Take heed of false prophets. In the which that they might be the more careful, He reminds them of the things that were done among their fathers, calling them false prophets; for even in that day the like things fell out.

Yet He may seem here to have aimed under the title of false prophets, not so much at the heretic, as at those who, while their life is corrupt, yet wear an outward face of virtuousness; whence it is said, By their fruits ye shall know them. For among heretics it is possible many times to find a good life, but among those I have named never.

And a hypocrite is easily discerned; for the way they are commanded to walk is a hard way, and the hypocrite is loth to toil. And that you may not say that you are unable to find out them that are such, He again enforces what He had said by example from men, saying, Do men gather grapes of thorns, or figs of thistles?

But that none should say, An evil tree brings forth indeed evil fruit, but it brings forth also good, and so it becomes hard to discern, as it has a two-fold produce; on this account He adds, A good tree cannot bring forth evil fruit, neither can an evil tree bring forth good fruit.

He had not enjoined them to punish the false prophets, and therefore shows them the terrors of that punishment that is of God, saying, Every tree that bringeth not forth good fruit shall be hewn down, and cast into the fire. In these words He seems to aim also at the Jews, and thus calls to mind the word of John the Baptist, denouncing punishment against them in the very same words. For he had thus spoken to the Jews, warning them of the axe impending, the tree that should be cut down, and the fire that could not be extinguished. But if one will examine somewhat closely, here are two punishments, to be cut down, and to be burned; and he that is burned is also altogether cut out of the kingdom; which is the harder punishment. Many indeed fear no more than hell; but I say that the fall of that glory is a far more bitter punishment, than the pains of hell itself. For what evil great or small would not a father undergo, that he might see and enjoy a most dear son? Let us then think the same of that glory; for there is no son so dear to his father as is the rest of the good, to be deceased and to be with Christ. The pain of hell is indeed intolerable, yet are ten thousand hells nothing to falling from that blessed glory, and being held in hate by Christ.

"Beware of false prophets, for they will come to you in sheep's clothing, but inwardly they are ravening wolves." Behold together with the dogs and swine another kind of ambush and conspiracy, far more grievous than that. For those are acknowledged and open, but these shaded over. For which cause also, while from those He commanded to hold off, these He charged men to watch with exact care, as though it were not possible to see them at the first approach. Wherefore He also said, "beware"; making us more exact to discern them.

Then, lest when they had heard that it was narrow and strait, and that they must walk on a way opposite to the many, and must keep themselves from swine and dogs, and together with these from another more wicked kind, even this of wolves; lest, I say, they should sink down at this multitude of vexations, having both to go a way contrary to most men, and therewith again to have such anxiety about these things: He reminded them of what took place in the days of their fathers, by using the term, "false prophets," for then also no less did such things happen. Be not now, I pray you, troubled (so He speaks), for nothing new nor strange is to befall you. Since for all truth the devil is always secretly substituting its appropriate deceit.

And by the figure of "false prophets," here, I think He shadows out not the heretics, but them that are of a corrupt life, yet wear a mask of virtue; whom the generality are wont to call by the name of impostors. Wherefore He also said further,

"By their fruits ye shall know them."

For amongst heretics one may often find actual goodness, but amongst those whom I was mentioning, by no means.

"What then," it may be said, "if in these things too they counterfeit?" "Nay, they will be easily detected; for such is the nature of this way, in which I commanded men to walk, painful and irksome; but the hypocrite would not choose to take pains, but to make a show only; wherefore also he is easily convicted." Thus, inasmuch as He had said, "there be few that find it," He clears them out again from among those, who find it not, yet feign so to do, by commanding us not to look to them that wear the masks only, but to them who in reality pursue it.

"But wherefore," one may say, "did He not make them manifest, but set us on the search for them?" That we might watch, and be ever prepared for conflict, guarding against our disguised as well as against our open enemies: which kind indeed Paul also was intimating, when he said, that "by their good words they deceive the hearts of the simple." Let us not be troubled therefor, when we see many such even now. Nay, for this too Christ foretold from the beginning.

And see His gentleness: how He said not, "Punish them," but, "Be not hurt by them," "Do not fall amongst them unguarded." Then that thou mightest not say, "it is impossible to distinguish that sort of men," again He states an argument from a human example, thus saying,

"Do men gather grapes of thorns, or figs of thistles? even so every good tree bringeth forth good fruit, but the corrupt tree bringeth forth evil fruit. A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit."

Now what He saith is like this: they have nothing gentle nor sweet; it is the sheep only so far as the skin; wherefore also it is easy to discern them. And lest thou shouldest have any the least doubt, He compares it to certain natural necessities, in matters which admit of no result but one. In which sense Paul also said, "The carnal mind is death; for it is not subject to the law of God, neither indeed can be."

And if He states the same thing twice, it is not tautology. But, lest any one should say, "Though the evil tree bear evil fruit, it bears also good, and makes the distinction difficult, the crop being twofold:" "This is not so," saith He, "for it bears evil fruit only, and never can bear good: as indeed in the contrary case also."

"What then? Is there no such thing as a good man becoming wicked? And the contrary again takes place, and life abounds with many such examples."

But Christ saith not this, that for the wicked there is no way to change, or that the good cannot fall away, but that so long as he is living in wickedness, he will not be able to bear good fruit. For he may indeed change to virtue, being evil; but while continuing in wickedness, he will not bear good fruit.

What then? did not David, being good, bear evil fruit? Not continuing good, but being changed; since, undoubtedly, had he remained always what he was, he would not have brought forth such fruit. For not surely while abiding in the habit of virtue, did he commit what he committed.

Now by these words He was also stopping the mouths of those who speak evil at random, and putting a bridle on the lips of all calumniators. I mean, whereas many suspect the good by reason of the bad, He by this saying hath deprived them of all excuse. "For thou canst not say, 'I am deceived and beguiled;' since I have given thee exactly this way of distinguishing them by their works, having added the injunction to go to their actions, and not to confound all at random."

"For by their fruits," saith He, "ye shall know them." And what commends our own life? Is it indeed a display of miracles, or the perfection of an excellent conversation? Very evidently it is the second; but as to the miracles, they both have their origin from hence, and terminate herein. For both He that shows forth an excellent life, draws to Himself this gift, and he that receives the gift, receives it for this end, that he may amend other men's lives. Since even Christ for this end wrought those miracles, that having made Himself thereby credible, and drawn men unto Him, He might bring virtue into our life. Wherefore also He lays more stress of the two on this. For He is not at all satisfied with the signs only, but He also threatens hell, and promises a kingdom, and lays down those startling laws, and all things He orders to this end, that He may make us equal to the angels.

Then forasmuch as He had not commanded to punish, but only to beware of them, He, at once both to comfort those whom they vex, and to alarm and change them, set up as a bulwark against them the punishment they should receive at His hands, saying,

"Every tree that bringeth not forth good fruit is hewn down, and cast into the fire."

Then, to make the saying less grievous, He added,

"Wherefore by their fruits ye shall know them."

That He might not seem to introduce the threatening as His leading topic, but to be stirring up their mind in the way of admonition and counsel.

Here He seems to me to be hinting at the Jews also, who were exhibiting such fruits. Wherefore also He reminded them of the sayings of John, in the very same terms delineating their punishment. For he too said the very same, making mention to them of an "axe," and of a "tree cut down," and of "unquenchable fire."

And though it appear indeed to be some single judgment, the being burnt up, yet if one examine carefully, these are two punishments. For he that is burnt is also cast of course out of God's kingdom; and this latter punishment is more grievous than the other. Now I know indeed that many tremble only at hell, but I affirm the loss of that glory to be a far greater punishment than hell. And if it be not possible to exhibit it such in words, this is nothing marvellous. For neither do we know the blessedness of those good things, that we should on the other hand clearly perceive the wretchedness ensuing on being deprived of them; since Paul, as knowing these things clearly, is aware, that to fall from Christ's glory is more grievous than all. And this we shall know at that time, when we shall fall into the actual trial of it.

But may this never be our case, O thou only-begotten Son of God, neither may we ever have any experience of this irremediable punishment. For how great an evil it is to fall from those good things, cannot indeed be accurately told: nevertheless, as I may be able, I will labor and strive by an example to make it clear to you, though it be but in some small degree.

Let us then imagine a wondrous child, having besides His virtue the dominion of the whole world, and in all respects so virtuous, as to be capable of bringing all men to the yearning of a father's affection. What theft do you think the father of this child would not gladly suffer, not to be cast out of His society? And what evil, small or great, would he not welcome, on condition of seeing and enjoying Him? Now let us reason just so with respect to that glory also. For no child, be he never so virtuous, is so desirable and lovely to a father, as the having our portion in those good things, and "to depart and be with Christ."

No doubt hell, and that punishment, is a thing not to be borne. Yet though one suppose ten thousand hells, he will utter nothing like what it will be to fail of that blessed glory, to be hated of Christ, to hear "I know you not," to be accused for not feeding Him when we saw Him an hungered. Yea, better surely to endure a thousand thunderbolts, than to see that face of mildness turning away from us, and that eye of peace not enduring to look upon us. For if He, while I was an enemy, and hating Him, and turning from Him, did in such wise follow after me, as not to spare even Himself, but to give Himself up unto death: when after all this I do not vouchsafe to Him so much as a loaf in His hunger, with what kind of eyes shall I ever again behold Him?

Attend to the words, for they have an especial force, many walk in the broad way—few find the narrow way. For the broad way needs no search, and is not found, but presents itself readily; it is the way of all who go astray. Whereas the narrow way neither do all find, nor when they have found, do they straightway walk therein. Many, after they have found the way of truth, caught by the pleasures of the world, desert midway.

What is here spoken of false prophets we may apply to all whose dress and speech promise one thing, and their actions exhibit another. But it is specially to be understood of heretics, who by observing temperance, chastity, and fasting, surround themselves as it were with a garment of sanctity, but inasmuch as their hearts within them are poisoned, they deceive the souls of the more simple brethren.

We would ask those heretics who affirm that there are two natures directly opposed to each other, if they admit that a good tree cannot bring forth evil fruit, how it was possible for Moses, a good tree, to sin as he did at the water of contradiction? Or for Peter to deny his Lord in the Passion, saying, I know not the man? Or how, on the other hand, could Moses' father-in-law, an evil tree, inasmuch as he believed not in the God of Israel, give good counsel?

(Verse 15 and following) Beware of false prophets, who come to you in sheep's clothing but inwardly are ravenous wolves. You will recognize them by their fruits. Are grapes gathered from thornbushes, or figs from thistles? So, every healthy tree bears good fruit, but the diseased tree bears bad fruit. And by their fruits you will know them. It is possible to understand all things, as those who promise one thing in appearance and speech but show another thing in action. But especially, this should be understood about heretics, who seem to clothe themselves in the appearance of piety through continence, chastity, and fasting, but inwardly they have a poisoned heart and deceive the minds of the simple brothers. Therefore, from the fruits of the soul, which drag innocence to ruin, they are compared to ravenous wolves.

(Serm. in Mont. ii. 24.) Wherefore it is justly asked, what fruits then He would have us look to? For many esteem among fruits some things which pertain to the sheep's clothing, and in this manner are deceived concerning wolves. For they practise fasting, almsgiving, or praying, which they display before men, seeking to please those to whom these things seem difficult. These then are not the fruits by which He teaches us to discern them. Those deeds which are done with good intention, are the proper fleece of the sheep itself, such as are done with bad intention, or in error, are nothing else than a clothing of wolves; but the sheep ought not to hate their own clothing because it is often used to hide wolves. What then are the fruits by which we may know an evil tree? The Apostle says, The works of the flesh are manifest, which are, fornication, uncleanness, &c. (Gal. 5:19.) And which are they by which we may know a good tree? The same Apostle teaches, saying, The fruits of the Spirit are love, joy, peace.

(non occ.) But from their actions we may conjecture whether this their outward appearance is put on for display. For when by any temptations those things are withdrawn or denied them which they had either attained or sought to attain by this evil, then needs must that it appear whether they be the wolf in sheep's clothing, or the sheep in his own.

And in [the interpretation of] this passage we must be very much on our guard against the error of those who judge from these same two trees that there are two original natures, the one of which belongs to God, but the other neither belongs to God nor springs from Him. And this error has both been already discussed in other books [of ours] very copiously, and if that is still too little, will be discussed again; but at present we have merely to show that the two trees before us do not help them. In the first place, because it is so clear that He is speaking of men, that whoever reads what goes before and what follows will wonder at their blindness. Secondly, they fix their attention on what is said, A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit, and therefore think that neither can it happen that an evil soul should be changed into something better, nor a good one into something worse; as if it were said, A good tree cannot become evil, nor an evil tree good. But it is said, A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. For the tree is certainly the soul itself, i.e. the man himself, but the fruits are the works of the man; an evil man, therefore, cannot perform good works, nor a good man evil works. If an evil man, therefore, wishes to perform good works, let him first become good. So the Lord Himself says in another passage more plainly: Either make the tree good, or make the tree bad. But if He were figuratively representing the two natures of such parties by these two trees, He would not say, Make: for who of the sons of men can make a nature? Then also in that passage, when He had made mention of these two trees, He added, You hypocrites, how can you, being evil, speak good things? As long, therefore, as any one is evil, he cannot bring forth good fruits; for if he were to bring forth good fruits, he would no longer be evil. So it might most truly have been said, snow cannot be warm; for when it begins to be warm, we no longer call it snow, but water. It may therefore come about, that what was snow is no longer so; but it cannot happen that snow should be warm. So it may come about, that he who was evil is no longer evil; it cannot, however, happen that an evil man should do good. And although he is sometimes useful, this is not the man's own doing; but it is done through him, in virtue of the arrangements of divine providence: as, for instance, it is said of the Pharisees, What they bid you, do; but what they do, do not consent to do. This very circumstance, that they spoke things that were good, and that the things which they spoke were usefully listened to and done, was not a matter belonging to them: for, says He, they sit in Moses' seat. It was, therefore, when engaged through divine providence in preaching the law of God, that they were able to be useful to their hearers, although they were not so to themselves. Respecting such it is said in another place by the prophet, They have sown wheat, but shall reap thorns; because they teach what is good, and do what is evil. Those, therefore, who listened to them, and did what was said by them, did not gather grapes of thorns, but through the thorns gathered grapes of the vine: just as, were any one to thrust his hand through a hedge, or were at least to gather a grape from a vine which was entangled in a hedge, that would not be the fruit of the thorns, but of the vine.

The question, indeed, is most rightly put, What are the fruits He would wish us to attend to, whereby we might know the tree? For many reckon among the fruits certain things which belong to the sheep's clothing, and in this way are deceived by wolves: as, for instance, either fastings, or prayers, or almsgivings; but unless all of these things could be done even by hypocrites, He would not say above, Take heed that you do not your righteousness before men, to be seen of them. And after prefixing this sentence, He goes on to speak of those very three things, almsgiving, prayer, fasting. For many give largely to the poor, not from compassion, but from vanity; and many pray, or rather seem to pray, while not keeping God in view, but desiring to please men; and many fast, and make a wonderful show of abstinence before those to whom such things appear difficult, and by whom they are reckoned worthy of honour: and catch them with artifices of this sort, while they hold up to view one thing for the purpose of deceiving, and put forth another for the purpose of preying upon or killing those who cannot see the wolves under that sheep's clothing. These, therefore, are not the fruits by which He admonishes us that the tree is known. For such things, when they are done with a good intention in sincerity, are the appropriate clothing of sheep; but when they are done in wicked deception, they cover nothing else but wolves. But the sheep ought not on this account to hate their own clothing, because the wolves often conceal themselves therein.

What the fruits are by the finding of which we may know an evil tree, the apostle tells us: Now the works of the flesh are manifest, which are these; adulteries, fornications, uncleanness, lasciviousness, idolatry, witchcraft, hatreds, variances, emulations, wrath, strife, seditions, heresies, envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God. And what the fruits are by which we may know a good tree, the very same apostle goes on to tell us: But the fruit of the Spirit is love, joy, peace, long-suffering, gentleness, goodness, faith, meekness, temperance. It must be known, indeed, that joy stands here in a strict and proper sense; for bad men are, strictly speaking, not said to rejoice, but to make extravagant demonstrations of joy: just as we have said above, that will which the wicked do not possess, stands in a strict sense where it is said, All things whatsoever ye would that men should do to you, do ye even so to them. In accordance with that strict sense of the word, in virtue of which joy is spoken of only in the good, the prophet also speaks, saying: Rejoicing is not for the wicked, says the Lord. So also faith stands, not certainly as meaning any kind of it, but true faith: and the other things which find a place here have certain resemblances of their own in bad men and deceivers; so that they entirely mislead, unless one has the pure and single eye by which he may know such things. It is accordingly the best arrangement, that the cleansing of the eye is first discussed, and then mention is made of what things were to be guarded against.

The Lord had before commanded His Apostles, that they should not do their alms, prayers, and fastings before men, as the hypocrites; and that they might know that all these things may be done in hypocrisy, He speaks saying, Take heed of false prophets.

What is written below that the Law and the Prophets were until John, (Mat. 11:13.) is said, because there should be no prophecy concerning Christ after He was come. Prophets indeed there have been and are, but not prophesying of Christ, rather interpreting the things which had been prophesied of Christ by the ancients, that is by the doctors of the Churches. For no man can unfold prophetic meaning, but the Spirit of prophecy. The Lord then knowing that there should be false teachers, warns them of divers heresies, saying, Take heed of false prophets. And forasmuch as they would not be manifest Gentiles, but lurk under the Christian name, He said not 'See ye,' but, Take heed. For a thing that is certain is simply seen, or looked upon; but when it is uncertain it is watched or narrowly considered. Also He says Take heed, because it is a sure precaution of security to know him whom you avoid. But this form of warning, Take heed, does not imply that the Devil will introduce heresies against God's will, but by His permission only; but because He would not choose servants without trial, therefore He sends them temptation; and because He would not have them perish through ignorance, He therefore warns them beforehand. Also that no heretical teacher might maintain that He spoke here of Gentile and Jewish teachers and not of them, He adds, who come to yon in sheep's clothing. Christians are called sheep, and the sheep's clothing is a form of Christianity and of feigned religion. And nothing so casts out all good as hypocrisy; for evil that puts on the semblance of good, cannot be provided against, because it is unknown. Again, that the heretic might not allege that He here speaks of the true teachers which were yet sinners, He adds, But inwardly they are ravening wolves. But Catholic teachers should they indeed have been sinners, are spoken of as servants of the flesh, yet not as ravening wolves, because it is not their purpose to destroy Christians. Clearly then it is of heretical teachers that He speaks; for they put on the guise of Christians, to the end they may tear in pieces the Christian with the wicked fangs of seduction. Concerning, such the Apostle speaks, I know that after my departure there will enter among you grievous wolves, not sparing the flock. (Acts 20:29.)

The fruits of a man are the confession of his faith and the works of his life; for he who utters according to God the words of humility and a true confession, is the sheep; but he who against the truth howls forth blasphemies against God, is the wolf.

The grape has in it a mystery of Christ. As the bunch sustains many grapes held together by the woody stem, so likewise Christ holds many believers joined to Him by the wood of the Cross. The fig again is the Church which binds many faithful by a sweet embrace of charity, as the fig contains many seeds inclosed in one skin. The fig then has these significations, namely, love in its sweetness, unity in the close adhesion of its seeds. In the grape is shown patience, in that it is cast into the wine-press—joy, because wine maketh glad the heart of man—purity, because it is not mixed with water—and sweetness, in that it delighteth. The thorns and thistles are the heretics. And as a thorn or a thistle has sharp pricks on every part, so the Devil's servants, on whatsoever side you look at them, are full of wickedness. Thorns and thistles then of this sort cannot bear the fruits of the Church. And having instanced in particular trees, as the fig, the vine, the thorn, and the thistle, He proceeds to show that this is universally true, saying, Thus every good tree bringeth forth good fruit, but an evil tree bringeth forth evil fruit.

(Mor. xxxi. 14.) Also the hypocrite is restrained by peaceful times of Holy Church, and therefore appears clothed with godliness; but let any trial of faith ensue, straight the wolf ravenous at heart strips himself of his sheep's skin, and shows by persecuting how great his rage against the good.

And man is denominated a good tree, or a bad, after his will, as it is good or bad. His fruit is his works, which can neither be good when the will is evil, nor evil when it is good.

. The heretics are cunning and deceitful, which is why He says, "Beware." They produce sweet words and feign a decent life, but within lies the hook. "Sheep’s clothing" is meekness, which some pretend to employ, in order to flatter and to deceive. But they are recognized by their "fruit," that is, by their deeds and by their life. For though they can dissemble for a time, they are unmasked by those who are heedful.

(non occ.) From the foregoing similitude He draws the conclusion to what He had said before, as being now manifest, saying, Therefore by their fruits ye shall know them.

The bad (natural) tree cannot produce good fruit. But oddly, it can produce fruits that by all external tests are indistinguishable from the good ones: the act done from one's own separate and unredeemed, tho' 'moral' will, looks exactly like the act done by Christ in us. And oddly enough it is the tree's real duty to go on producing these imitation fruits till it recognises this futility and despairs and is made a new (spiritual) tree. The trouble in the XVIth century was that Luther - who intuited the truth - was fundamentally an uneducated man, a peasant type: and really let the whole question get immediately entangled with political and ecclesiological questions which were really quite irrelevant to it. But the whole question must now be raised again.

What most people who talk about Reunion don't realise is that continental Protestantism regards the Church of England as still theologically 'un-reformed' and the Lutheran-Anglican gap is really at present at least as wide as the Anglical-Roman. It is thus a three cornered affair.
