4 And that because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage:
(Vers. 3-5.) But not even Titus, who was with me, though he was a Gentile, was compelled to be circumcised. Yet because of false brothers secretly brought in—who slipped in to spy out our freedom that we have in Christ Jesus, so that they might bring us into slavery— to them we did not yield in submission even for a moment, so that the truth of the gospel might be preserved for you. But even Titus, who was with me, was not compelled to be circumcised, although he was a Gentile. This matter arose because of false brothers secretly brought in, who slipped in to spy out our freedom that we have in Christ Jesus, so that they might bring us into slavery. But what is this truth of the Gospel, to give in to the hypocrisy of the Jews; and to consider as scybala what you once esteemed, and to despise as losses, and to observe and esteem as something, when they are nothing? But it strongly opposes the meaning of the Epistle itself, to call the Galatians back to circumcision. This is the main theme throughout his discourse, to teach that he is a Hebrew among the Hebrews, once observing all the works of the Law, circumcised on the eighth day according to the Law of the Pharisees: nevertheless, for the grace of Christ, to completely despise everything. For when he went to Jerusalem, and the false brethren, who believed in circumcision, wanted to compel him to circumcise Titus; neither Titus, nor did he give in to violence, so that they would safeguard the truth of the Gospel. But if he says that he was compelled by necessity to circumcise Titus: how does he recall the Galatians from circumcision, from which neither Titus, who was with him from the Gentiles, could excuse himself in Jerusalem? Therefore, according to the Greek manuscripts, it should be read, 'To whom we did not yield in subjection, not even for an hour,' so that it may be understood subsequently: so that the truth of the Gospel may remain with you. But if the testimony of the Latin exemplars is pleasing to anyone, we must understand it according to the higher sense: that the purpose was not for Titus to be circumcised, but to go to Jerusalem. For this reason, Paul and Barnabas submitted to going to Jerusalem, due to the sedition caused by the Law of Antioch. This was done so that the truth of the Gospel would be confirmed by the letter of the apostles and remain among the Galatians, which was not in the literal sense, but in the spiritual sense. It was not in the carnal understanding, but in spiritual intelligence, and not in overt Judaism, but in hidden understanding. It is worth knowing that the conjunction 'autem,' which is placed in this position, is superfluous if it is read without any purpose to respond to it and if it concludes the previous statement. However, it serves to maintain the order of reading and the sense of the passage. So, Titus, who was with me, being a Gentile, was not compelled to be circumcised. And immediately after, it explains the reason why he was being urged to undergo circumcision against his will. 'Because of the false brothers secretly brought in, who slipped in to spy out our freedom that we have in Christ Jesus, so that they might bring us into slavery.' But when they were serving as ministers and wished to drag us into the servitude of the Law from the freedom of Christ, we did not even yield to them for a moment, so that we might not give any occasion to them to accuse us. And we did this primarily because of the ecclesiastical peace, so that we could excuse ourselves from necessity, and we did all of this so that you would not have any opportunity to depart from the grace of the Gospel. Therefore, if we, while in Jerusalem, among so many Jews who were falsely claiming to be brothers and those who were exerting influence over us to some extent, could not be compelled by force or reason to observe the circumcision that we knew was abolished, then you, coming from the Gentiles, you in Galatia, you to whom no violence can be done, voluntarily abandoning the grace, have transcended the antiquity of the already abolished Law.
So great had been his desire to be approved and supported by those whom you wish on all occasions to be understood as in alliance with Judaism! When indeed he says, that "neither was Titus circumcised," he for the first time shows us that circumcision was the only question connected with the maintenance of the law, which had been as yet agitated by those whom he therefore calls "false brethren unawares brought in." These persons went no further than to insist on a continuance of the law, retaining unquestionably a sincere belief in the Creator.
Therefore he says: "Because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ, that they might bring us into bondage, to whom we gave place by subjection not even for an hour." Let us only attend to the clear sense and to the reason of the thing, and the perversion of the Scripture will be apparent.
For up to the present time both the Gentiles and the Jews of the circumcision watch and busy themselves with the dealings of the Church, desiring to suborn false witnesses against us, as the apostle says: "And that because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ Jesus."
By “secretly” he means that they had entered by deception, passing themselves off as brothers when they were enemies. By “slipped in” he means that they came in a humble manner, feigning friendship.… To “spy out” is to enter in such a way as to invent one thing and discover another, whereby they may challenge our liberty.… “Liberty in Jesus Christ” means not being subject to the law. “That they might bring us into bondage” means … to subject us to the law of circumcision.
Ver. 4. "And that because of the false brethren, privily brought in."
Here arises a very important question, Who were these false brethren? If the Apostles permitted circumcision at Jerusalem, why are those who enjoined it, in accordance with the Apostolic sentence, to be called false brethren? First; because there is a difference between commanding an act to be done, and allowing it after it is done. He who enjoins an act, does it with zeal as necessary, and of primary importance; but he who, without himself commanding it, allows another to do it who wishes yields not from a sense of its being necessary but in order to subserve some purpose. We have a similar instance, in Paul's Epistle to the Corinthians, in his command to husbands and wives to come together again. To which, that he might not be thought to be legislating for them, he subjoins, "But this I say by way of permission, not of commandment." [1 Corinthians 7:5] For this was not a judgment authoritatively given but an indulgence to their incontinence; as he says, "for your incontinency." Would you know Paul's sentence in this matter? Hear his words, "I would that all men were even as I myself," [1 Corinthians 7:7] in continence. And so here, the Apostles made this concession, not as vindicating the law, but as condescending to the infirmities of Judaism. Had they been vindicating the law, they would not have preached to the Jews in one way, and to the Gentiles in another. Had the observance been necessary for unbelievers, then indeed it would plainly have likewise been necessary for all the faithful. But by their decision not to harass the Gentiles on this point, they showed that they permitted it by way of condescension to the Jews. Whereas the purpose of the false brethren was to cast them out of grace, and reduce them under the yoke of slavery again. This is the first difference, and a very wide one. The second is, that the Apostles so acted in Judæa, where the Law was in force, but the false brethren, every where, for all the Galatians were influenced by them. Whence it appears that their intention was, not to build up, but entirely to pull down the Gospel, and that the thing was permitted by the Apostles on one ground and zealously practiced by the false brethren on another.
Ver. 4. "Who came in privily to spy out our liberty, which we have in Christ Jesus, that they might bring us into bondage."
He points out their hostility by calling them spies; for the sole object of a spy is to obtain for himself facilities of devastation and destruction, by becoming acquainted with his adversary's position. And this is what those did, who wished to bring the disciples back to their old servitude. Hence too appears how very contrary their purpose was to that of the Apostles; the latter made concessions that they might gradually extricate them from their servitude, but the former plotted to subject them to one more severe. Therefore they looked round and observed accurately and made themselves busybodies to find out who were uncircumcised; as Paul says, "they came in privily to spy out our liberty," thus pointing out their machinations not only by the term "spies," but by this expression of a furtive entrance and creeping in.
No small thing is at stake here. The question is, if the apostles at this point consented to circumcision, why did Paul apply the term “false brothers” to those who also imposed circumcision in accordance with the sentiment of the apostles? First of all, it is one thing actively to impose an act and another passively to consent to it once done. For the one who zealously imposes it makes it necessary and paramount. But the one who, without imposing it, does not prevent the one who wants it, does not consent to it as a necessity but rather through passive consent seeks to accomplish other purposes. … Second, the apostles did this only in Judea, but the false apostles had gone about everywhere. They had all the Galatians in their grip.
The preposition ‘because of’ (dia) was put here instead of ‘according to’ (kata). But the sense is this. The Apostles, he says, did not force Titus, who was uncircumcised, to be circumcised, although this was pointed out by the brethren who were brought in secretly and pressed for circumcision. Indeed he put them in the place of spies because of what is foreign to the truth.
That they might introduce us again, he says, into the slavery of the law. This is why elsewhere he says, Christ purchased us from the curse of the law (Gal. 3:13).
