Two Trees
Two Trees Matthew 7:15-20
Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves. Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles? Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit. A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. Wherefore by their fruits ye shall know them.
SUMMARY: There are many wolves that carry captive those that are running towards God. He who inquires of a false prophet in regard to any action is an idolater, and devoid of the truth, and foolish. There are, therefore, and there were many, who, coming forward in the name of Jesus, taught both to speak and act impious and blasphemous things. False Christs, false prophets, and false apostles have come to split up the one Church into parts through their corrupting doctrines. There are those who inwardly are wolves, yet wear sheep's clothing in the eyes of the world. For the false prophets possessed the prophetic name dishonestly, being prophets, but prophets of the liar. One who sets forth in detail things yet to be, was rightly judged a prophet. What are these sheep’s clothing, but the external surface of the Christian profession? Who are the ravening wolves but those deceitful senses and spirits which are lurking within to waste the flock of Christ? Who are the false prophets but deceptive predictors of the future? Therefore from their ways shall the false prophet and the prophet be known. Converting into unholy persons, manifests them to be enemies of God and false prophets. The tree is made manifest by its fruit; so those that profess themselves to be Christ’s are known not only by what they say, but by what they practice. For the fruits of the prophet must needs be brought to the test: for “from its fruit is the tree known”. It may be called a good tree if, through its power of choice, it appoints good things; or it may be called evil if it should choose evil things. A man is unfruitful when he is carnal. An honest mind and good faith cannot produce evil deeds, any more than an evil disposition can produce good deeds. If, however, a tree continues alone, not producing fruit fully formed, it is utterly destroyed. Ignatius: Do not err, my brothers and sisters. Those that corrupt families shall not inherit the kingdom of God. If, then, those who do this as respects the flesh have suffered death, how much more shall this be the case with any one who corrupts by wicked doctrine the faith of God, for which Jesus Christ was crucified! Such an one becoming defiled in this way, shall go away into everlasting fire, and so shall every one that listens to him.

IGNATIUS: For there are many wolves that appear worthy of credit who, by means of a pernicious pleasure, carry captive those that are running towards God; but in your unity they shall have no place.

HERMAS: He pointed out to me some men sitting on a seat, and one man sitting on a chair. And he says to me, “Do you see the men sitting on the seat?” “I do, sir,” I said. “These,” he says, “are the faithful, and he who sits on the chair is a false prophet, ruining the minds of the servants of God. It is the doubters, not the faithful, that he ruins. These doubters then go to him as to a soothsayer, and inquire of him what will happen to them; and he, the false prophet, not having the power of a Divine Spirit in him, answers them according to their inquiries, and according to their wicked desires, and fills their souls with expectations, according to their own wishes. For being himself empty, he gives empty answers to empty inquirers; for every answer is made to the emptiness of man. Some true words he does occasionally utter; for the devil fills him with his own spirit, in the hope that he may be able to overcome some of the righteous. As many, then, as are strong in the faith of the Lord, and are clothed with truth, have no connection with such spirits, but keep away from them; but as many as are of doubtful minds and frequently repent, go to soothsaying, even as the heathen, and bring greater sin upon themselves by their idolatry. For he who inquires of a false prophet in regard to any action is an idolater, and devoid of the truth, and foolish. For no spirit given by God requires to be asked; but such a spirit having the power of Divinity speaks all things of itself, for it proceeds from above from the power of the Divine Spirit. But the spirit which is asked and speaks according to the desires of men is earthly, light, and powerless, and it is altogether silent if it is not questioned.” “How then, sir,” I ask, “will a man know which of them is the prophet, and which the false prophet?” “I will tell you,” he says, “about both the prophets, and then you can try the true and the false prophet according to my directions. Try the man who has the Divine Spirit by his life. First, he who has the Divine Spirit proceeding from above is meek, and peaceable, and humble, and refrains from all iniquity and the vain desire of this world, and contents himself with fewer wants than those of other men, and when asked he makes no reply; nor does he speak privately, nor when man wishes the spirit to speak does the Holy Spirit speak, but it speaks only when God wishes it to speak. When, then, a man having the Divine Spirit comes into an assembly of righteous men who have faith in the Divine Spirit, and this assembly of men offers up prayer to God, then the angel of the prophetic Spirit, who is destined for him, fills the man; and the man being filled with the Holy Spirit, speaks to the multitude as the Lord wishes. Thus, then, will the Spirit of Divinity become manifest. Whatever power therefore comes from the Spirit of Divinity belongs to the Lord. “Hear, then,” he says, “in regard to the spirit which is earthly, and empty, and powerless, and foolish. First, the man who seems to have the Spirit exalts himself, and wishes to have the first seat, and is bold, and impudent, and talkative, and lives in the midst of many luxuries and many other delusions, and takes rewards for his prophecy; and if he does not receive rewards, he does not prophesy. Can, then, the Divine Spirit take rewards and prophesy? It is not possible that the prophet of God should do this, but prophets of this character are possessed by an earthly spirit. Then it never approaches an assembly of righteous men, but shuns them. And it associates with doubters and the vain, and prophesies to them in a corner, and deceives them, speaking to them, according to their desires, mere empty words: for they are empty to whom it gives its answers. For the empty vessel, when placed along with the empty, is not crushed, but they correspond to each other. When, therefore, it comes into an assembly of righteous men who have a Spirit of Divinity, and they offer up prayer, that man is made empty, and the earthly spirit flees from him through fear, and that man is made dumb, and is entirely crushed, being unable to speak. For if you pack closely a storehouse with wine or oil, and put an empty jar in the midst of the vessels of wine or oil, you will find that jar empty as when you placed it, if you should wish to clear the storehouse. So also the empty prophets, when they come to the spirits of the righteous, are found on leaving to be such as they were when they came. This, then, is the mode of life of both prophets. Try by his deeds and his life the man who says that he is inspired. But as for you, trust the Spirit which comes from God, and has power; but the spirit which is earthly and empty do not trust at all, for there is no power in it: it comes from the devil. Hear, then, the parable which I am to tell you. Take a stone, and throw it to the sky, and see if you can touch it. Or again, take a squirt of water and squirt into the sky, and see if you can penetrate the sky.” “How, sir,” I ask, “can these things take place? For both of them are impossible.” “As these things,” he says, “are impossible, so also are the earthly spirits powerless. But look, on the other hand, at the power which comes from above. Hail is of the size of a very small grain, yet when it falls on a man’s head how much annoyance it gives him! Or, again, take the drop which falls from a pitcher to the ground, and yet it hollows a stone. You see, then, that the smallest things coming from above have great power when they fall upon the earth. Thus also is the Divine Spirit, which comes from above, powerful. Trust, then, that Spirit, but have nothing to do with the other.”

Justin Martyr: And let those who are not found living as He taught, be understood to be no Christians, even though they profess with the lip the precepts of Christ; for not those who make profession, but those who do the works, shall be saved, according to His word: “For many shall come in My name, clothed outwardly in sheep’s clothing, but inwardly being ravening wolves. By their works you shall know them. And every tree that does not bring forth good fruit, is hewn down and cast into the fire.”

Justin Martyr: The fact that there are such men confessing themselves to be Christians, and admitting the crucified Jesus to be both Lord and Christ, yet not teaching His doctrines, but those of the spirits of error, causes us who are disciples of the true and pure doctrine of Jesus Christ, to be more faithful and steadfast in the hope announced by Him. For what things He predicted would take place in His name, these we do see being actually accomplished in our sight. For he said, “Many shall come in My name, clothed outwardly in sheep’s clothing, but inwardly they are ravening wolves.” . . . There are, therefore, and there were many, my friends, who, coming forward in the name of Jesus, taught both to speak and act impious and blasphemous things; and these are called by us after the name of the men from whom each doctrine and opinion had its origin.

Justin Martyr: There existed, long before this time, certain men more ancient than all those who are esteemed philosophers, both righteous and beloved by God, who spoke by the Divine Spirit, and foretold events which would take place, and which are now taking place. They are called prophets. These alone both saw and announced the truth to men, neither reverencing nor fearing any man, not influenced by a desire for glory, but speaking those things alone which they saw and which they heard, being filled with the Holy Spirit. Their writings are still extant, and he who has read them is very much helped in his knowledge of the beginning and end of things, and of those matters which the philosopher ought to know, provided he has believed them. For they did not use demonstration in their treatises, seeing that they were witnesses to the truth above all demonstration, and worthy of belief; and those events which have happened, and those which are happening, compel you to assent to the utterances made by them, although, indeed, they were entitled to credit on account of the miracles which they performed, since they both glorified the Creator, the God and Father of all things, and proclaimed His Son, the Christ sent by Him: which, indeed, the false prophets, who are filled with the lying unclean spirit, neither have done nor do, but venture to work certain wonderful deeds for the purpose of astonishing men, and glorify the spirits and demons of error. But pray that, above all things, the gates of light may be opened to you; for these things cannot be perceived or understood by all, but only by the man to whom God and His Christ have imparted wisdom.

Justin Martyr: The prophetical gifts remain with us, even to the present time. And therefore you ought to understand that the gifts formerly among your nation, the Jews, have been transferred to us, the Christians. And just as there were false prophets in the same time period with your holy prophets, so are there now many false teachers among us, of whom our Lord forewarned us to beware; so that in no respect are we deficient, since we know that He foreknew all that would happen to us after His resurrection from the dead and ascension to heaven. For He said we would be put to death, and hated for His name’s sake; and that many false prophets and false Christs would appear in His name, and deceive many: and so has it come about. For many have taught godless, blasphemous, and unholy doctrines, forging them in His name; have taught, too, and even yet are teaching, those things which proceed from the unclean spirit of the devil, and which were put into their hearts. Therefore we are most anxious that you be persuaded not to be misled by such persons, since we know that every one who can speak the truth, and yet does not speak it, shall be judged by God, as God testified by Ezekiel, when He said, “I have made you a watchman to the house of Judah. If the sinner sin, and you do not warn him, he himself shall die in his sin; but his blood will I require at your hand. But if you warn him, you shall be innocent.” And on this account we are, through fear, very earnest in desiring to converse with men according to the Scriptures, but not from love of money, or of glory, or of pleasure. For no man can convict us of any of these vices. No more do we wish to live like the rulers of your people, whom God reproaches when He says, “Your rulers are companions of thieves, lovers of bribes, followers of the rewards.” Now, if you know certain among us to be of this sort, do not for their sakes blaspheme the Scriptures and Christ, and do not diligently strive to give falsified interpretations.

HEGESIPPUS: The Church was called a virgin, for she was not as yet corrupted by worthless teaching. Thebulis it was who, displeased because he was not made bishop, first began to corrupt her by stealth. He too was connected with the seven sects which existed among the people, like Simon, from whom come the Simoniani; and Cleobius, from whom come the Cleobiani; and Doritheus, from whom come the Dorithiani; and Gorthaeus, from whom come the Gortheani; Masbothaeus, from whom come the Masbothaei. From these men also come the Menandrianists, and the Marcionists, and the Carpocratians, and the Valentinians, and the Basilidians, and the Saturnilians. Each of these leaders in his own private and distinct capacity brought in his own private opinion. From these have come false Christs, false prophets, false apostles—men who have split up the one Church into parts through their corrupting doctrines, uttered in disparagement of God and of His Christ.

IRENAEUS: Certain men have set the truth aside, and bring in lying words and vain genealogies, which, as the apostle says, “minister questions rather than godly edifying which is in faith,” and by means of their craftily-constructed plausibilities draw away the minds of the inexperienced and take them captive. These men falsify the oracles of God, and prove themselves evil interpreters of the good word of revelation. They also overthrow the faith of many, by drawing them away, under a pretense of superior knowledge, from Him who rounded and adorned the universe; as if they had something more excellent and sublime to reveal, than that God who created the heaven and the earth, and all things that are therein. By means of specious and plausible words, they cunningly allure the simple-minded to inquire into their system; but they nevertheless clumsily destroy them, while they initiate them into their blasphemous and impious opinions . . . and these simple ones are unable, even in such a matter, to distinguish falsehood from truth. Error, indeed, is never set forth in its naked deformity, lest, being thus exposed, it should at once be detected. But it is craftily decked out in an attractive dress, so as, by its outward form, to make it appear to the inexperienced, ridiculous as the expression may seem, more true than the truth itself. One far superior to me has well said, in reference to this point, “A clever imitation in glass casts contempt, as it were, on that precious jewel the emerald, which is most highly esteemed by some, unless it come under the eye of one able to test and expose the counterfeit. Or, again, what inexperienced person can with ease detect the presence of brass when it has been mixed up with silver?” Lest, therefore, through my neglect, some should be carried off, even as sheep are by wolves, while they perceive not the true character of these men,—because they outwardly are covered with sheep’s clothing, against whom the Lord has enjoined us to be on our guard, and because their language resembles ours, while their sentiments are very different,—I have deemed it my duty . . . to unfold to you, my friend, these portentous and profound mysteries, which do not fall within the range of every intellect, because all have not sufficiently purged their brains. I do this, in order that you, obtaining an acquaintance with these things, may in turn explain them to all those with whom you are connected, and exhort them to avoid such an abyss of madness and of blasphemy against Christ.

IRENAEUS: It appears probable enough that this man possesses a demon as his familiar spirit, by means of whom he seems able to prophesy, and also enables as many as he counts worthy to be partakers of his Charis themselves to prophesy. He devotes himself especially to women, and those such as are well-bred, and elegantly attired, and of great wealth, whom he frequently seeks to draw after him, by addressing them in seductive words. . . . But already some of the most faithful women, possessed of the fear of God, and not being deceived (whom, nevertheless, he did his best to seduce like the rest by bidding them prophesy), abhorring and cursing him, have withdrawn from such a vile company of revelers. This they have done, as being well aware that the gift of prophecy is not conferred on men by Marcus, the magician, but that only those to whom God sends His grace from above possess the divinely-bestowed power of prophesying; and then they speak where and when God pleases, and not when Marcus orders them to do so.

IRENAEUS: Moreover, those also will be thus refuted who belong to Simon and Carpocrates, heretical teachers, and if there be any others who are said to perform miracles, who do not perform what they do either through the power of God, or in connection with the truth, nor for the well-being of men, but for the sake of destroying and misleading mankind, by means of magical deceptions, and with universal deceit, thus entailing greater harm than good on those who believe them, with respect to the point on which they lead them astray. For they can neither confer sight on the blind, nor hearing on the deaf, nor chase away all sorts of demons, none, indeed, except those that are sent into others by themselves, if they can even do so much as this. Nor can they cure the weak, or the lame, or the paralytic, or those who are distressed in any other part of the body, as has often been done in regard to bodily infirmity. Nor can they furnish effective remedies for those external accidents which may occur. And so far are they from being able to raise the dead, as the Lord raised them, and the apostles did by means of prayer, and as has been frequently done in the brotherhood on account of some necessity, the entire Church in that particular locality entreating with much fasting and prayer, the spirit of the dead man has returned, and he has been bestowed in answer to the prayers of the saints, that they do not even believe this can be possibly be done, and hold that the resurrection from the dead is simply an acquaintance with that truth which they proclaim. Since, therefore, there exist among them error and misleading influences, and magical illusions are impiously wrought in the sight of men; but in the Church, sympathy, and compassion, and steadfastness, and truth, for the aid and encouragement of mankind, are not only displayed without fee or reward, but we ourselves lay out for the benefit of others our own means; and inasmuch as those who are cured very frequently do not possess the things which they require, they receive them from us. Since such is the case, these men are in this way undoubtedly proved to be utter aliens from the divine nature, the beneficence of God, and all spiritual excellence. But they are altogether full of deceit of every kind, apostate inspiration, demoniacal working, and the phantasms of idolatry, and are in reality the predecessors of that dragon who, by means of a deception of the same kind, will with his tail cause a third part of the stars to fall from their place, and will cast them down to the earth. It behooves us to flee from them, the Gnostics, as we would from him; and the greater the display with which they are said to perform their marvels, the more carefully should we watch them, as having been endowed with a greater spirit of wickedness. If any one will consider the prophecy referred to, and the daily practices of these men, he will find that their manner of acting is one and the same with the demons.

IRENAEUS: There are those who inwardly are wolves, yet wear sheep's clothing in the eyes of the world; and that God has always preserved freedom, and the power of self-government in man, while at the same time He issued His own exhortations, in order that those who do not obey Him should be righteously judged (condemned) because they have not obeyed Him; and that those who have obeyed and believed on Him should be honored with immortality.

IRENAEUS: He shall judge false prophets, who, without having received the gift of prophecy from God, and not possessed of the fear of God, but either for the sake of vainglory, or with a view to some personal advantage, or acting in some other way under the influence of a wicked spirit, pretend to utter prophecies, while all the time they lie against God.

TATIAN: Beware of false prophets, which come to you in sheep’s clothing, while within they are ravening wolves. But by their fruits you shall know them. For every tree is known by its fruit. For figs are not gathered of thorns, neither are grapes plucked of briers. Even so every good tree brings forth good fruit, but the evil tree brings forth evil fruit. The good tree cannot bring forth evil fruit, neither can the evil tree bring forth good fruit. The good man from the good treasures that are in his heart brings forth good things; and the evil man from the evil treasures that are in his heart brings forth evil things: and from the overflowings of the heart the lips speak. Every tree that does not bear good fruit is cut down and cast into the fire. Therefore by their fruits you shall know them.

Clement of Alexandria: The devil is called “thief and robber;” having mixed false prophets with the prophets, as tares with the wheat. “All, then, that came before the Lord, were thieves and robbers;” not absolutely all men, but all the false prophets, and all who were not properly sent by Him. For the false prophets possessed the prophetic name dishonestly, being prophets, but prophets of the liar. For the Lord says, “You are of your father the devil; and the lusts of your father you will do. He was a murderer from the beginning, and he did not abide in the truth, because there is no truth in him. When he speaks a lie, he speaks of his own; for he is a liar, and the father of it.” But among the lies, the false prophets also told some true things. And in reality they prophesied “in an ecstasy,” as the servants of the apostate. And the Shepherd, the angel of repentance, says to Hermas, of the false prophet: “For he speaks some truths. For the devil fills him with his own spirit, if perchance he may be able to cast down any one from what is right.”

HIPPOLYTUS: For as the blessed prophets were made, so to speak, eyes for us, they foresaw through faith the mysteries of the word, and became ministers of these things also to succeeding generations, not only reporting the past, but also announcing the present and the future, so that the prophet might not appear to be one only for the time being, but might also predict the future for all generations, and so be reckoned a true prophet. For these fathers were furnished with the Spirit, and largely honored by the Word Himself; and just as it is with instruments of music, so had they the Word always, like the plectrum, in union with them, and when moved by Him the prophets announced what God willed. For they did not speak of their own power, let there be no mistake as to that, neither did they declare what pleased themselves. But first of all they were endowed with wisdom by the Word, and then again were rightly instructed in the future by means of visions. And then, when thus themselves fully convinced, they spoke those things which were revealed by God to them alone, and concealed from all others. For with what reason should the prophet be called a prophet, unless he in spirit foresaw the future? For if the prophet spoke of any chance event, he would not be a prophet then in speaking of things which were under the eye of all. But one who sets forth in detail things yet to be, was rightly judged a prophet.

TERTULLIAN: But let us rather be mindful of the sayings of the Lord, and of the letters of the apostles; for they have both told us beforehand that there shall be heresies, and have given us, in anticipation, warnings to avoid them; and inasmuch as we are not alarmed because they exist, so we ought not to wonder that they are capable of doing that, on account of which they must be shunned. The Lord teaches us that many “ravening wolves shall come in sheep’s clothing.” Now, what are these sheep’s clothing’s, but the external surface of the Christian profession? Who are the ravening wolves but those deceitful senses and spirits which are lurking within to waste the flock of Christ? Who are the false prophets but deceptive predictors of the future? Who are the false apostles but the preachers of a spurious gospel? Who also are the Antichrists, both now and evermore, but the men who rebel against Christ?

Alexander of Alexandria: Although we grieve at the destruction of these men, the heretics of Arianism, especially that after having once learned the doctrine of the Church, they have now gone back; yet we do not wonder at it; for this very thing Hymenaeus and Philetus suffered, and before them Judas, who, though he followed the Savior, afterwards became a traitor and an apostate. Moreover, concerning these very men, warnings are not lacking to us, for the Lord foretold: “Take heed that you are not deceived: for many shall come in My Name, saying, I am Christ; and the time draws near: therefore do not go after them.” Paul, too, having learned these things from the Savior, wrote, “In the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils which turn away from the truth.” The Didache: Whosoever, therefore, comes and teaches you all these things that have been said before, receive him. But if the teacher himself turn and teach another doctrine to the destruction of this, do not hear him; but if he teaches so as to increase righteousness and the knowledge of the Lord, receive him as the Lord. But concerning the apostles and prophets, according to the decree of the Gospel, thus do. Let every apostle that comes to you be received as the Lord. But he shall not remain except one day; but if there be need, also the next; but if he remains three days, he is a false prophet. And when the apostle goes away, let him take nothing but bread until he lodges; but if he ask money, he is a false prophet. And every prophet that speaks in the Spirit you shall neither try nor judge; for every sin shall be forgiven, but this sin shall not be forgiven. But not every one that speaks in the Spirit is a prophet; but only if he hold the ways of the Lord. Therefore from their ways shall the false prophet and the prophet be known. And every prophet who orders a meal in the Spirit does not eat from it, except indeed he be a false prophet; and every prophet who teaches the truth, if he does not do what he teaches, is a false prophet. And every prophet, proved true, working unto the mystery of the Church in the world, yet not teaching others to do what he himself does, shall not be judged among you, for with God he has his judgment; for so did also the ancient prophets. But whoever says in the Spirit, “Give me money,” or something else, you shall not listen to him; but if he says to you to give for others’ sake who are in need, let no one judge him. But let every one that comes in the name of the Lord be received, and afterward you shall prove and know him; for you shall have understanding right and left. If he who comes is a wayfarer, assist him as far as you are able; but he shall not remain with you, except for two or three days, if need be. But if he wills to abide with you, being an artisan, let him work and eat; but if he has no trade, according to your understanding see to it that, as a Christian, he shall not live with you idle. But if he wills not to do, he is a shame. Watch that you keep your distance from such. But every true prophet that wills to abide among you is worthy of his support. So also a true teacher is himself worthy, as the workman, of his support. Every first-fruit, therefore, of the products of wine-press and threshing-floor, of oxen and of sheep, you shall take and give to the prophets, for they are your high priests. But if you do not have a prophet, give it to the poor. If you make a batch of dough, take the first-fruit and give according to the commandment. So also when you open a jar of wine or of oil, take the first-fruit and give it to the prophets; and of money, silver, and clothing and every possession, take the first-fruit, as it may seem good to you, and give according to the commandment. Watch for your life’s sake. Do not let your lamps be quenched, nor your loins unloosed; but be ready, for you do not know the hour in which our Lord comes. But often you shall come together, seeking the things which are befitting to your souls: for the whole time of your faith will not profit you, if you are not made perfect in the last time. For in the last days false prophets and corrupters shall be multiplied, and the sheep shall be turned into wolves, and love shall be turned into hate; for when lawlessness increases, they shall hate and persecute and betray one another, and then shall appear the world-deceiver as the Son of God, and shall do signs and wonders, and the earth shall be delivered into his hands, and he shall do iniquitous things which have never yet come to pass since the beginning. Then shall the creation of men come into the fire of trial, and many shall be made to stumble and shall perish; but they that endure in their faith shall be saved from under the curse itself. And then shall appear the signs of the truth; first, the sign of an out-spreading in heaven; then the sign of the sound of the trumpet; and the third, the resurrection of the dead; yet not of all, but as it is said: “The Lord shall come and all His saints with Him.” Then shall the world see the Lord coming upon the clouds of heaven.

LACTANTIUS: But since many heresies have existed, and the people of God have been torn into divisions at the instigation of demons, the truth must be briefly marked out by us, and placed in its own peculiar dwelling-place, that if any one shall desire to draw the water of life, he may not be borne to broken cisterns which hold no water, but may know the abundant fountain of God, watered by which he may enjoy perpetual light. Before all things, it is fitting that we should know both that He Himself and His ambassadors foretold that there must be numerous sects and heresies, which would break the unity of the sacred body; and that they admonished us to be on our guard with the greatest prudence, lest we should at any time fall into the snares and deceits of that adversary of ours, with whom God has willed that we should contend. Then that He gave us sure commands, which we ought always to treasure in our minds; for many, forgetting them, and abandoning the heavenly road, have made for themselves devious paths amidst windings and precipices, by which they might lead away the incautious and simple part of the people to the darkness of death: I will explain how this happened. There were some of our religion whose faith was less established, or who were less learned or less cautious, who tore the unity and divided the Church. But they whose faith was unsettled, when they pretended that they knew and worshipped God, aiming at the increase of their wealth and honor, aspired to the highest sacerdotal power; and when overcome by others more powerful, preferred to secede with their supporters, than to endure those set over them, over whom they themselves before desired to be set. But some, not sufficiently instructed in heavenly learning, when they were unable to reply to the accusers of the truth, who objected that it was either impossible or inconsistent that God should be shut up in the womb of a woman, and that the Majesty of heaven could not be reduced to such weakness as to become an object of contempt and derision, a reproach and mockery to men; lastly, that He should even endure tortures, and be affixed to the accursed cross; and when they could defend and refute all these things neither by talent nor learning, for they did not thoroughly perceive their force and meaning, they were perverted from the right path, and corrupted the sacred writings, so that they composed for themselves a new doctrine without any root and stability. But some, enticed by the prediction of false prophets, concerning whom both the true prophets and he himself had foretold, fell away from the knowledge of God, and left the true tradition. But all of these, ensnared by frauds of demons, which they ought to have foreseen and guarded against, by their carelessness lost the name and worship of God. For when they are called Phrygians, or Novatians, or Valentinians, or Marcionites, or Anthropians, or Arians, or by any other name, they have ceased to be Christians, who have lost the name of Christ, and assumed human and external names. Therefore it is the catholic Church alone which retains true worship. This is the fountain of truth, this is the abode of the faith, this is the temple of God; into which if any one shall not enter, or from which if any shall go out, he is estranged from the hope of life and eternal salvation. No one ought to flatter himself with persevering strife. For the contest is respecting life and salvation, which, unless it is carefully and diligently kept in view, will be lost and extinguished. But, however, because all the separate assemblies of heretics call themselves Christians in preference to others, and think that theirs is the catholic Church, it must be known that the true catholic Church is that in which there is confession and repentance, which treats in a wholesome manner the sins and wounds to which the weakness of the flesh is liable. I have related these things in the meanwhile for the sake of admonition, that no one who desires to avoid error may be entangled in a greater error, while he is ignorant of the secret of the truth. Afterwards, in a particular and separate work, we will more fully and copiously contend against all divisions of falsehoods.

Clement of Alexandria: It is the manner of life which shows up those who know the commandments; for as a man's word is, so is his life. The tree is known by its fruit, not by its blossom and leaves. Knowledge, then, comes from the fruit and from behavior, not from talk and from blossom. We say that knowledge is not mere talk, but a certain divine knowledge, that light which is kindled in the soul as a result of obedience to the commandments, and which reveals all that is in a state of becoming, enables man to know himself and teaches him to become possessed of God. Apollonius: But who is this new teacher, Montanus, a heretic? His works and teaching inform us. This is he who taught the dissolution of marriage; who instilled fasting; who craftily contrives the taking of gifts under the name of voluntary offerings; who grants stipends to those who publish abroad his doctrine, that by means of gluttony the teaching of the doctrine may prevail. We declare to you, then, that these first prophetesses, as soon as they were filled with the spirit, left their husbands. Do you not think that all Scripture forbids a prophet to receive gifts and money? Therefore, when I see that the prophetess has received gold and silver and expensive articles of dress, how can I avoid treating her with disapproval? For whereas the Lord has said, “Provide neither gold, nor silver, nor two coats a piece,” these men have, on the flat contrary, transgressed the command by the acquisition of these forbidden things. For we shall show that those who are called among them prophets and martyrs obtain money not only from the rich, but also from the poor, from orphans and widows. And if they are confident that they are right in so doing, let them stand forward and discuss the point, in order that, if they be refuted, they may cease for the future so to transgress. For the fruits of the prophet must needs be brought to the test: for “from its fruit is the tree known.” If they deny that their prophets have taken gifts, let them confess thus much, that if they be convicted of having taken them, they are not prophets; and we will cite ten thousand proofs that they have. It is proper, too, that all the fruits of a prophet should be examined. Tell me: does a prophet dye his hair? Does a prophet pencil his eyelids? Is a prophet fond of dress? Does a prophet play at gaming-tables and dice? Does a prophet lend money on interest? Let them confess whether these things are allowable or not. For my part, I will prove that these practices have occurred among them.

ORIGEN: It may be called a good tree if, through its power of choice, it appoints good things; or it may be called evil if it should choose evil things. And in this way, each person, according to the impulses of his own purpose, will be designated either a good olive tree, if he travels down the road of virtue, or a wild olive tree, if he follows the opposite path. This, after all, is why even the Lord was saying in the Gospel, “Either make the tree good and its fruit good; or make the tree evil and its fruit evil,” in order to show that a tree, good or evil, is made, not born. Clement of Alexandria: On laughter: People who are imitators of ludicrous sensations, or rather of such as deserve derision, are to be driven from our polity. For since all forms of speech flow from mind and manners, ludicrous expressions could not be uttered, did they not proceed from ludicrous practices. For the saying, “It is not a good tree which produces corrupt fruit, nor a corrupt tree which produces good fruit,” is to be applied in this case. For speech is the fruit of the mind. If, then, facetious jokers are to be ejected from our society, we ourselves must by no manner of means be allowed to stir up laughter. For it would be absurd to be found imitators of things of which we are prohibited to be listeners; and still more absurd for a man to set about making himself a laughing-stock, that is, the butt of insult and derision. For if we could not endure to make a ridiculous figure, such as we see some do in processions, how could we with any propriety bear to have the inner man made a ridiculous figure of, and that to one’s face? Therefore we ought never of our own accord to assume a ludicrous character. And how, then, can we devote ourselves to being and appearing ridiculous in our conversation, thereby perverting speech, which is the most precious of all human endowments? It is therefore disgraceful to set one’s self to do this; since the conversation of facetious jokers of this description is not fit for our ears, inasmuch as by the very expressions used it familiarizes us with shameful actions. Pleasantry is allowable, not facetious joking. Besides, even laughter must be kept in check; for when given vent to in the right manner it indicates orderliness, but when it issues differently it shows a lack of restraint.

TERTULLIAN: “The good tree does not bring forth corrupt fruit, neither the corrupt tree good fruit.” Which means, that an honest mind and good faith cannot produce evil deeds, any more than an evil disposition can produce good deeds.

HIPPOLYTUS: For he is unfruitful when he is carnal, and causes the desire of the flesh. This, he says, is what is spoken: “Every tree not producing good fruit, is cut down and cast into the fire.”

HIPPOLYTUS: There will not be chaff and wood begotten for fire, but mature fruit, fully formed, equal and similar to the unbegotten and indefinite power. If, however, a tree continues alone, not producing fruit fully formed, it is utterly destroyed. For somewhere near, he says, is the axe which is laid at the roots of the tree. Every tree, he says, which does not produce good fruit, is hewn down and cast into fire.

CYPRIAN: It is of small account to be baptized and to receive the Eucharist, unless one profit by it both in deeds and works. In the first Epistle of Paul to the Corinthians: “Do you not know that they which run in a race all run indeed, although one receives the prize? So run, that you may obtain. And those indeed that they may receive a corruptible crown, but we an incorruptible.” In the Gospel according to Matthew: “Every tree that does not bring forth good fruit shall be cut down, and cast into the fire.” Also in the same place: “Many shall say to me in that day, 'Lord, Lord, have we not prophesied in Your name, and in Your name have cast out devils, and in Your name have done great works?' And then shall I say to them, I never knew you; depart from me, you who work iniquity.”
