Which is not another, only there are some that trouble you, and would pervert the gospel of Christ.

“For nobody had induced them to apostatize from the Creator, that they should seem to "be removed to another gospel," simply when they return again to the Creator. When he adds, too, the words, "which is not another," he confirms the fact that the gospel which he maintains is the Creator's. So that there are two gospels for two gods; and the apostle made a great mistake when he said that "there is not another" gospel, since there is (on the hypothesis) another; and so he might have made a better defence of his gospel, by rather demonstrating this, than by insisting on its being but one.”

“"Which is not another Gospel." And justly, for there is not another. Nevertheless the Marcionites are misled by this phrase, as diseased persons are injured even by healthy food, for they have seized upon it, and exclaim, "So Paul himself has declared there is no other Gospel." For they do not allow all the Evangelists, but one only, and him mutilated and confused according to their pleasure. Their explanation of the words, "according to my Gospel and the preaching of Jesus Christ," is sufficiently ridiculous; nevertheless, for the sake of those who are easily seduced, it is necessary to refute it. We assert, therefore, that, although a thousand Gospels were written, if the contents of all were the same, they would still be one, and their unity no wise infringed by the number of writers. So, on the other hand, if there were one writer only, but he were to contradict himself, the unity of the things written would be destroyed. For the oneness of a work depends not on the number of its authors, but on the agreement or contradictoriness of its contents. Whence it is clear that the four Gospels are one Gospel; for, as the four say the same thing, its oneness is preserved by the harmony of the contents, and not impaired by the difference of persons. "Only there are some that trouble you, and would pervert the Gospel of Christ." That is to say, ye will not recognize another Gospel, so long as your mind is sane, so long as your vision remains healthy, and free from distorted and imaginary phantoms. For as the disordered eye mistakes the object presented to it, so does the mind when made turbid by the confusion of evil thoughts. Thus the madman confounds objects; but this insanity is more dangerous than a physical malady, for it works injury not in the regions of sense, but of the mind; it creates confusion not in the organ of bodily vision, but in the eye of the understanding. "And would pervert the Gospel of Christ." They had, in fact, only introduced one or two commandments, circumcision and the observance of days, but he says that the Gospel was subverted, in order to show that a slight adulteration vitiates the whole. For as he who but partially pares away the image on a royal coin renders the whole spurious, so he who swerves ever so little from the pure faith, soon proceeds from this to graver errors, and becomes entirely corrupted. Where then are those who charge us with being contentious in separating from heretics, and say that there is no real difference between us except what arises from our ambition? Let them hear Paul's assertion, that those who had but slightly innovated, subverted the Gospel. Not to say that the Son of God is a created Being, is a small matter. Know you not that even under the elder covenant, a man who gathered sticks on the sabbath, and transgressed a single commandment, and that not a great one, was punished with death? and that Uzzah, who supported the Ark when on the point of being overturned, was struck suddenly dead, because he had intruded upon an office which did not pertain to him? Wherefore if to transgress the sabbath, and to touch the falling Ark, drew down the wrath of God so signally as to deprive the offender of even a momentary respite, shall he who corrupts unutterably awful doctrines find excuse and pardon? Assuredly not. A want of zeal in small matters is the cause of all our calamities; and because slight errors escape fitting correction, greater ones creep in.”

“Above, the greeting came first; in what follows, the epistolary narrative follows, in which the Apostle argues against their error. Second, he admonishes them to correction, in chapter 5, where he says stand fast therefore, and so on. Now he argues against their error in two ways: both through the authority of the evangelical teaching, and through the reasoning of the Old Testament, in chapter 3, where he says O foolish, and so on. He argues against their error, then, by showing the authority of the evangelical teaching. First by showing their own fickleness as regards the light dismissal of the evangelical teaching; second by commending the authority of that evangelical teaching itself, so that the more worthy what they are dismissing is shown to be, the greater their error appears — where he says for I make known to you, and so on. Concerning the first he does two things. First he aggravates the fault; second he inflicts the penalty, where he says but though we, and so on. Now he aggravates the fault both of those who are being led astray and of those who are leading them astray, where he says unless there are some, and so on. Concerning the first he does three things. First he aggravates the fault of those being seduced from the fickleness of their mind. Hence he says I marvel — as if to say: since you know how many good things have been said to have come to you through Christ, and that although you were so well instructed by me, nevertheless so, that is, to such an extent and so vehemently, that you seem already to have forgotten, so soon, that is, in so short a time, you are removed — so as to play on the name; for Galatia is said to mean "removal" or "translation." As if to say: you are Galatians, because you are removed so quickly. Ecclesiasticus 19:4: he who believes quickly is light of heart. Second, he aggravates their fault from that which they left. For if reason withdraws and is transferred away from evil, it is commendable and does well; but when it withdraws from the good, then it is culpable. And thus these men had been transferred away from the good. And therefore he says to them: and if it is to be marveled at that you are removed so quickly and thus, he nevertheless adds matter for wonder, namely that you are removed from him, that is, from God, and from his faith, who called you into the grace of Christ, that is, into participation in the eternal good, which we have through Christ. 1 Peter 2:9: giving thanks to God, who has called you into his wonderful light. Likewise 2 Peter 2:21: it would have been better for them not to have known the way of truth, than, and so on. Third, he aggravates their fault from that to which they have been turned, because they have not been turned to the good, but to evil. Hence he says unto another gospel, that is, of the old law, which is a good annunciation insofar as it announces certain goods, namely temporal and carnal ones. Isaiah 1:9: if you be willing and will hearken to me, and so on. But nevertheless it is not perfect and simply so, as the Gospel is; because it does not announce perfect and greatest goods, but small and least ones. But the new law is perfectly and simply the Gospel, that is, a good annunciation, because it announces the greatest goods, namely heavenly, spiritual, and eternal ones. And although it be another gospel according to the tradition of the false apostles, nevertheless according to my preaching it is not. For it is other in its promises, but it is not other in its figure, because the same thing is contained in the Old Testament and in the New: in the Old indeed as in figure, in the New indeed as in the reality and expressly. And thus it is another gospel as regards those things which appear outwardly, but as regards those things which are within and are contained, it is not other. But although it is not other in itself, nevertheless it can become other through the fault of others, namely of those who are leading astray. And therefore, aggravating their fault, he says unless there are some, namely seducers, who trouble you, that is, who becloud the purity of your understanding, with which you had been imbued through the truth of the faith. Because, although the same thing is contained as regards the inner understanding through the Old and New Testament, as has been said, nevertheless if after the reception of the New Testament the Old is repeated, it seems to be shown that the New is not perfect, and that the one is other than the other. And therefore he says that it is not other, unless there are some, etc., because these false apostles, after the reception of the evangelical faith, were compelling them to be circumcised, showing through this that circumcision is something other than Baptism and effects something that Baptism cannot effect, and therefore these men are troubling you. Below, 5:12: I would that they were even cut off who trouble you, and so on. And they truly trouble you, because they wish to convert the Gospel of Christ, that is, the truth of the evangelical teaching into the figure of the law, which is absurd and the greatest disturbance. For a thing ought to be converted into that toward which it is ordered; but the New Testament and the Gospel of Christ is not ordered toward the Old, but rather on the contrary the old law is ordered toward the new law, as figure toward truth; and therefore the figure ought to be converted into the truth, and the old law into the Gospel of Christ, but not the truth into the figure, nor the Gospel of Christ into the old law: which is clear from the very usage of speech. For we do not say that a man is like the image of a man, but rather the other way around, the image is like the man. Jeremiah 15:9: they themselves shall be turned to thee, etc.; and Leviticus 26:10: new things coming upon you, and so on. Consequently, after the aggravation of the fault, the infliction of the penalty is set down, when he says but though, and so on. And concerning this he does two things. First he promulgates the sentence; second he assigns the reason for the sentence, where he says for do I now persuade men, and so on. Concerning the first he does two things. First he shows the authority of his sentence; second he pronounces it, where he says as I have said before, and so on. Now he shows that the authority of his sentence is great, in that it would have efficacy not only against perverters and against seducers who are subjects, but even against equals, such as the other apostles are, and even against superiors, such as the Angels are, if they were guilty of this crime, namely of converting the Gospel into the old law. And therefore he says: for the authority of our sentence which I promulgate (which is excommunication) has efficacy not only against those who intend such things, but though we, namely the apostles, or an angel, good or bad, coming from heaven should preach a gospel besides that which has been preached by us, let him be anathema, that is, he shall be guilty of this sentence, which we promulgate. Now for the evidence of what has been said, three things must be inquired into. First, what this word "anathema" signifies. Concerning which it must be known that anathema is a Greek word, and it is compounded from ana, which is "up" or "upward," and thesis, "a positing," as it were "a placing on high." And it arose from a certain ancient custom. For the ancients, when they fought, would sometimes seize some plunder from the enemies, which they did not wish to convert to their own use, but they would hang it up in temples, or in some public place of the city, as it were set apart from the common use of men, and the Greeks called every such thing thus hung up anathema; and from this the custom grew up, that everything which was excluded from common use was said to be anathematized. Hence it is said in Joshua 6:17 concerning Jericho and all the things that are in it, that Joshua straightway anathematized them. And therefore this also grew up in the Church, that those who are excluded from the common fellowship of the Church, and from participation in the sacraments of the Church, are said to be anathematized. Second, the reason must be inquired into of what he says though we or an angel, and so on. Here it must be known that there is a threefold teaching. The first is that of the philosophers, who by the guidance of their own reason arrived at the knowledge of their teaching. There is another teaching, which is handed down through Angels, as the old law is. For the law was not brought forth by human will (as is said at Galatians 3:19), but through Angels in the hand of a mediator, as is said below at 3:19. But there is a certain teaching handed down by God immediately, as the teaching of the Gospel is. John 1:18: no man hath seen God at any time, and so on. Hebrews 1:2: in these last days hath spoken to us by his Son. And afterward: which having received a beginning, and so on. Therefore the teaching which is handed down through a man can be changed and revoked through another man who knows better, just as one philosopher refutes the sayings of another; likewise through an Angel who sees the truth more keenly. Also the teaching which is handed down through an Angel could perhaps be removed through another, superior Angel, or through God. But on the other hand the teaching which is handed down immediately by God cannot be made void either through a man or through an Angel. And therefore if it should happen that a man or an Angel should say something contrary to that which has been handed down by God, his own statement is not against the teaching, so as through this to be made void and rejected, but rather the teaching is against him, because he who speaks it ought to be excluded and rejected from the communion of that teaching. And therefore the Apostle says that the dignity of the evangelical teaching, which is handed down immediately by God, is of such great dignity, that whether a man or an Angel should preach a gospel other than that which has been preached in it, he is anathema, that is, he is to be cast out and rejected. Third, it is necessary to resolve the objections which occur concerning this. Of which one is: since an equal does not have authority over an equal, and much more does not have it over a superior, it seems that the Apostle could not excommunicate the apostles who were his equals, and still less the Angels who are superiors. Matthew 11:11: he that is the lesser in the kingdom of heaven is greater than he. Therefore it is not anathema through this. To this it must be said that the Apostle uttered this sentence, not by his own authority, but by the authority of the evangelical teaching, of which he was the minister, of which teaching the authority is such that whoever speak against it are to be excluded and rejected. John 10: the word that I have spoken, the same shall judge him in the last day, and so on. Another question is, because he himself says besides that which has been preached. Therefore no one ought to teach, or to preach, except what is written in the epistles and in the Gospel. But this is false, because it is said at 1 Thessalonians 3:10: that we may accomplish those things that are wanting to your faith, and so on. I respond. It must be said that nothing else is to be preached as gospel, than that which is contained in the Gospels, and in the epistles, and in sacred Scripture, implicitly or explicitly. For sacred Scripture and the Gospel preach that Christ is to be believed in explicitly. Hence whatever is contained in them implicitly, which serves toward his teaching, and toward the faith of Christ, can be preached and taught. And therefore when he says besides that, etc., that is, adding something wholly foreign. Apocalypse, at the end: if any man shall add to these things, or shall add, namely something wholly foreign, God shall add unto him the plagues written in this book. And Deuteronomy 4: you shall not add anything, etc., namely contrary or foreign, neither shall you take away, and so on. Consequently, when he says as I have said before, etc., he pronounces his sentence in respect of evil, saying: as I have said before concerning Angels and apostles, I say the same concerning the seducers. If any seducer shall preach a gospel besides that which you have received from me, let him be anathema, that is, excommunicated. And this is the sentence which he pronounces. But are all heretics excommunicated by this? It seems not, because it is said at Titus 3:10: a man that is a heretic, after the first and second admonition, avoid, and so on. I respond. It must be said that someone can be called a heretic either because he simply errs out of ignorance, and from this he is not excommunicated; or because he errs out of obstinacy and strives to pervert others, and then he incurs the canon of a sentence already passed. But whether from that time he pronounced sentence against heretics by these words is doubtful, since nevertheless sentence has already been passed against heretics in the Councils. It can nevertheless be said that perhaps here they are shown to be worthy of excommunication. Consequently, when he says for do I now persuade men, etc., he shows the reason for the sentence. Here first he sets down the reason for the sentence itself; second he here makes clear his purpose, where he says or do I seek, and so on. For someone could say: why do you excommunicate in this way? Perhaps some are friends, or persons of some authority, therefore it ought not to be done thus. Therefore the Apostle, responding, says: nay rather, it ought to be done thus, because these things which I now say are not for the favor of men, but that I may please God, and this is what he says for do I now, that is, after my conversion, or in this epistle, persuade men, that is, does my desire tend to this, that I might please men, or God? As if to say: these things which I do, I do for this reason, that I may please God alone. 1 Thessalonians 2:4: we speak not as pleasing men, but God, and so on. Nor indeed do we speak by the authority of men, but by the divine authority. But that I do not intend to please men is clear from my intention and from my purpose. For I do not seek to please men, that is, it is not of my intention to convert men, that I may please men only, but for the honor of God. And this is clear, because if I still intended to please men, as I once pleased them, I should not be the servant of Christ. The reason for which is that these things are contrary to one another. To this extent, namely, that I should wish to please men for the sake of men, not referring that to God. For if I should intend at some time to please men for this reason, that I might draw them to God, I do not sin. But if in the first way, I am not the servant of Christ. Isaiah 28:20: the bed is straitened, so that one must fall out, and so on. Matthew 6:24: no man can serve two masters, and so on. Psalm 52:6: they are confounded that please men.”

“Which is not another,.... It is no Gospel, no joyful sound, no good news, and glad tidings; the doctrine which attributes justification to the works of the law, or mixes grace and works in the business of salvation, which was the doctrine of these false teachers, is no Gospel; not truly so, however it may be called; nor does it bring any solid peace and joy to distressed minds. There is but one pure Gospel of the grace of God, and Christ, and his apostles; there is not one and another; there is but one faith, one doctrine and scheme of faith; the Gospel is single and uniform, all of a piece, has no yea and nay, or contradiction in it; this trumpet gives no uncertain sound, nor any dreadful, but a joyful one: but there be some that trouble you; meaning the false apostles, whose names he does not think fit to mention, as being unworthy to be named, and to have their names transmitted to posterity. These troubled the churches with their doctrines and principles, by raising disputes and controversies among them, injecting doubts and scruples into their minds, which puzzled and confounded them, and made them uneasy, and which broke in upon that peace of soul which the Gospel brings and establishes; for no true solid peace is attained to, and enjoyed, but by the doctrine of justification by the righteousness of Christ, pardon by his blood, and atonement by his sacrifice, which the doctrine of justification by works, &c. tends to destroy. And would pervert the Gospel of Christ; which has Christ for its author, subject, and preacher; and particularly the doctrine of justification by his righteousness, which they sought to change, to throw into a different shape and form, to adulterate by mixing it with the works of the law, and so, if possible, destroy it: to this they showed a good will, but were not able to effect, for the Gospel is an everlasting one; it is immovable, and so is that particular doctrine of it; it remains, and will remain in spite of opposition to it. Thus the apostle prudently lays the blame of the Galatians removing from the Gospel to another upon the false teachers, hoping he should be able to reclaim them by solid arguments, and gentle methods.”

“Which is not another - It is called a gospel, but it differs most essentially from the authentic narratives published by the evangelists. It is not gospel, i.e. good tidings, for it loads you again with the burdens from which the genuine Gospel has disencumbered you. Instead of giving you peace, it troubles you; instead of being a useful supplement to the Gospel of Christ, it perverts that Gospel. You have gained nothing but loss and damage by the change.”

“another--A distinct Greek word from that in Gal 1:6. Though I called it a gospel (Gal 1:6), it is not really so. There is really but one Gospel, and no other gospel. but--Translate, "Only that there are some that trouble you," &c. (Gal 5:10, Gal 5:12). All I meant by the "different gospel" was nothing but a perversion by "some" of the one Gospel of Christ. would pervert--Greek, "wish to pervert"; they could not really pervert the Gospel, though they could pervert Gospel professors (compare Gal 4:9, Gal 4:17, Gal 4:21; Gal 6:12-13; Col 2:18). Though acknowledging Christ, they insisted on circumcision and Jewish ordinances and professed to rest on the authority of other apostles, namely, Peter and James. But Paul recognizes no gospel, save the pure Gospel.”
