And many of the brethren in the Lord, growing confident by my bands, are much more bold to speak the word of God without fear.

“When (the apostle) mentions the several motives of those who were preaching the gospel, how that some, "waxing confident by his bonds, were more fearless in speaking the word," while others "preached Christ even out of envy and strife, and again others out of good-will" many also "out of love," and certain "out of contention," and some "in rivalry to himself," he had a favourable opportunity, no doubt, of taxing what they preached with a diversity of doctrine, as if it were no less than this which caused so great a variance in their tempers.”

“"And that most of the brethren in the Lord, being confident through my bonds, are more abundantly bold to speak the word without fear." This shows that they were of good courage even before, and spoke with boldness, but much more now. If others then, says he, are of good courage through my bonds, much more am I; if I am the cause of confidence to others, much more to myself. "And most of the brethren in the Lord." As it was a great thing to say, My bonds gave confidence to them, he therefore adds beforehand, "in the Lord." Do you see how, even when he sees himself constrained to speak great things, he departs not from moderation? "Are more abundantly bold," he says, "to speak the word without fear"; the words "more abundantly" show that they had already begun.”

“Having set out the matter of joy concerning future hope, he here shows for what he makes his prayer on their behalf. And first he sets forth his desire, which is shown to be utterly fervent; second, the matter of the prayer, at *and this I pray*, etc. And because the desire of the heart is manifest to God alone, therefore he calls God as witness that he prays for them with desire. Job ch. 12: *behold, in heaven is my witness*, namely God, etc. *How I long for you* — namely I — existing in the bowels of Jesus Christ. Or, how I long for you to be in them; as if he were to say: how I long for your salvation and participation in the visceral charity of Christ. Luke 1:78: *through the bowels of the mercy of God*, etc.; as if to say: because the power of love reaches to the depths and inmost parts of the heart. Or, I long that you be in the bowels of Jesus Christ, that is, that you love him intimately, so that you may also be loved by him; for in this consists the life of man. Then, when he says *and this I pray*, etc., he sets forth the prayer, and he desires three goods. First, as to the increase of interior charity. For interior affection is perfected through charity, and therefore for one who does not have charity, it should be desired that he have it; but for one who has it, that it be perfected. Hence he says *that charity*, etc. But for the increase of charity, God must be prayed to, because God alone works this in us. 2 Cor. 9:8: *And God is able to make all grace abound in you, that, always having all sufficiency in all things, you may abound unto every good work*, etc. And this it is necessary that we too ask, because Matt. 5:20: *unless your justice abound more than that of the Scribes and Pharisees, you shall not enter into the kingdom of heaven*. Second, as to the intellect. Hence he says *in all knowledge*. But does knowledge come from charity? Yes, because it is said in 1 John 2:27: *and as for you, let the anointing which you have received from him abide in you, and you have no need that any man teach you, but as his anointing teaches you concerning all things*, etc. Likewise, charity is the spirit, of which it is said in John 16:13: *when that spirit of truth shall come, he will teach you all*, etc. The reason for this is that whoever has a habit — if the habit is right, a right judgment follows from it concerning those things that pertain to that habit; but if it is corrupt, a false one. Just as, concerning venereal matters, the temperate man has good judgment, while the intemperate man does not, but a false one. But all things that are done by us are to be informed by charity, and therefore he who has charity has right judgment, also as to things knowable. And thus he says *in all knowledge*, namely by which he may recognize the truth and adhere firmly concerning those things that belong to faith. This is the knowledge of the saints, of which it is spoken in Wisdom 10:10. And as to things to be done, and thus he says *and in all sense*, which is the cognitive power concerning exterior objects. And it is proper to it that it immediately judges rightly concerning its proper sensible object. And therefore this name has been transferred to the interior judgment of reason; hence those are called "sensible" who have right judgment concerning things to be done. Wisdom 1:1: *have a sense of the Lord in goodness*, etc. Wisdom 6:16: *to think, then, upon her, is a consummated sense*, etc. But this sense ought to be not only considerative but also discretive between good and evil, and between good and better. Hence he adds *that you may approve*, etc. Note that charity perfects the sense so that it approves good things; but perfect charity, so that it approves better things. 1 Cor. 12:31: *be zealous for the better gifts*, etc.; and below, ch. 14: *follow after charity*, etc. And therefore he says *more excellent things*. Third, as to the effect. And first he sets forth immunity from evil; second, perfection in good. The first, in that he says *that you may be sincere*. For there is a twofold sin to be avoided: namely, that of interior corruption, by which a man is corrupted in himself, and this is excluded by sincerity. 1 Cor. 5:8: *in the unleavened bread of sincerity*, etc. The other is against one's neighbor, namely offense. And therefore he says *and without offense*. 1 Cor. 4:10: *be without offense to the Jews and the Gentiles, and to the Church of God, as I also*, etc. And 2 Cor. 6:3: *giving no offense to any man*, etc. *Unto the day of Christ Jesus*, that is, until the end of life. Matt. 24:13: *he who shall persevere unto the end, he shall be saved*. As to grace he says *filled with the fruit of justice*, so that the works of justice are, as it were, a fruit. Rom. 6:22: *you have your fruit unto sanctification*, etc. Or *the fruit of justice*, that is, the reward of justice, namely the crown. 2 Tim. 4:8: *as to the rest, there is laid up for me a crown of justice*, etc. Wisdom 4: *for the fruit of good labors is glorious*, etc. And this is had through Christ, because all things that we do are good through him. John 15:5: *without me you can do nothing*, etc. And these things are to be done for this end, namely unto the glory and praise of God, because from the works of the saints God is glorified, since others thereby break forth into the praise of God. Ps. 150:1: *praise the Lord in his saints*, etc. Jer. 33:9: *it shall be to me a name, and a joy, and a praise, and an exultation to all the nations of the earth, who shall hear of all the good things*, etc. Then, when he says *but I would have you know*, etc., he admonishes concerning things to come. And first he sets forth examples to be followed and to be avoided; second, he concludes with a moral admonition in ch. 4, at *therefore, my most beloved brethren*, etc. Concerning the first he does two things, for first he shows what things are to be imitated; second, what things are to be avoided, ch. 3, at *as for the rest*, etc. Likewise the first is divided into two, for first he puts himself forward for them to imitate; second, others, ch. 2, at *if there be therefore*, etc. Likewise the first into three, for first he sets forth as an example his own progress; second, the joy which he has from that progress, at *for what*, etc.; third, the fruit from his own progress, at *for I know*, etc. Likewise the first into two. First he sets forth the progress; second, the manner, at *so that my bonds*, etc. He says therefore: I have admonished you unto progress, and that you may have my progress as a pattern, I wish you to know, both the things that concern me — outwardly, because the tribulations, even though they were exterior, did not change me inwardly, but rather they turned out unto progress, since from them the faith preached made greater progress. 2 Cor. 1:6: *whether we be in tribulation, it is for your exhortation and salvation; or whether we be comforted, it is for your consolation*, etc. And he shows the progress. First as to himself; second as to others, at *so that the more*, etc. As to himself indeed it had been manifest that he suffered such things for Christ constantly, so that he was bound in chains, whence it is said *so that my bonds*, etc., which is glorious for Christ's sake. 1 Peter 4:15: *let none of you suffer as a murderer, or a thief, or a coveter of other men's goods; but if as a Christian, let him not be ashamed*, etc. *In every praetorium*, as in the court of Caesar, etc. But on the part of others, the faith was growing in common. Hence he says *so that the more*, etc. 1 Macc. ch. 4: concerning the elephants. Ecclus. 10:2: *according to the judge of the people, so also are his ministers*, etc. Prov. 18: *the just, like a confident lion, shall be without dread*, etc. Yet on the part of others there is diversity, because some spoke well, some ill. And those who spoke well, some did so out of general charity and some out of a special love for the apostle. And those who spoke ill, some did so out of general malice, some out of a special hatred toward the apostle. But as it seems to me, the apostle shows a twofold cause on account of which some were preaching. First, on account of envy. And therefore the apostle shows their depraved intention, saying *some indeed out of envy*, etc. James 3:16: *where jealousy and contention are, there is inconstancy, and every depraved work*. 1 Cor. 3:3: *since there is among you jealousy and contention, are you not carnal?* Second, on account of love of Christ and of the Gospel. Hence he says *some out of good*, etc. Ps. 150:20: *deal kindly, in good will*, etc. But the apostle adds, saying *but some out of charity*, namely that which produces good will, etc., because they preached in order to supply the deficiency of me as teacher. Then the apostle explains what he had said, stating that some preached not according to a sound intention, but out of contention. Their corrupt intention was manifest in two ways: in one way, that by preaching publicly, they might cause disturbance among the Gentile people against the apostle, over and above that which he already had. In the other way, because they believed that Paul, hearing them usurp the office committed to him, would be troubled, and thereby affliction would be added to one already afflicted.”

“And many of the brethren in the Lord,.... This is another instance of the usefulness of the apostle's sufferings, and another proof of their being for the furtherance of the Gospel; they were not only the means of the conversion of many that were without, but were very encouraging and strengthening to them that were within the church, and to many that were in the ministry; who are called "brethren", some real, others nominal; being partakers of the grace of God, at least in profession, or otherwise they would not have been fit to have been ministers of the word, nor members of a Gospel church, which was necessary to their being regularly sent forth; and whom the apostle calls and owns as brethren in the ministry, being sent forth by Christ, at least some of them, and having the same commission to preach the Gospel as he had; though they had not equal gifts and qualifications with him: he styles them brethren "in the Lord", to distinguish them from the Jews at Rome, who were his brethren according to the flesh; and to express their spiritual character and relation, and point out the work of the Lord, in which they were jointly concerned with him: now though not all the brethren, yet many of them were greatly affected with, and influenced by the apostle's patient and cheerfully suffering for Christ; insomuch that, as he says, waxing confident by my bonds, are much more bold to speak the word without fear; or as some read it, "waxing confident in the Lord"; connecting the phrase, "in the Lord", with this word, and so make the ground and object of their confidence the Lord; whose presence, power, grace, and Spirit, emboldened them the more by the apostle's bonds to preach the Gospel with courage and intrepidity; the Lord being on their side, and their helper, they feared not what men could do unto them; or else being animated by the apostle's patience and firmness of mind in suffering, and by the use they saw his bonds were of for the spread of the Gospel, they took heart and courage to "speak the word"; the word "of God", as the Vulgate Latin, Syriac, and Ethiopic versions read; and so the Alexandrian, Claromontane, and two of Stephens's copies: meaning either the essential word, the Lord Jesus Christ, who was the subject of their ministry; or the written word, the writings of Moses and the prophets, the books of the Old Testament, according to which they spoke; or the Gospel, called often the word, and sometimes with an addition, the word of truth, the word of faith, the word of reconciliation, the word of righteousness, the word of life, and the word of our salvation, from the several subjects of it: this they spake boldly and freely, as it ought to be spoken, and "without fear", not without fear and reverence of God, whose word it is; nor of themselves and their own weakness and inabilities, which cause much fear and trembling; but without the fear of man, which brings a snare; they had no regard to the threats and menaces, the reproaches and persecutions of men; none of these things moved them; they feared God and not man, and so went on boldly, preaching the Gospel; which is related with pleasure, as a fruit and effect of the apostle's sufferings, and which he doubted not would be very delightful to the Philippians to hear of.”

“Waxing confident - Finding the effect produced by the public defense which the apostle made, they were greatly encouraged, and the more boldly and openly proclaimed the doctrine of Christ crucified. The word - The doctrine of Christ; several excellent MSS. and versions add, some Θεου, others Κυριου, the word of God, or the word of the Lord. This is a respectable reading, and is probably genuine.”

“And many of, &c. encouraged by the intrepidity and perseverance of the apostle. (Calmet) — Knowing that sufferings undergone for the cause of Jesus Christ were most honourable, and the portion truly enviable of all the saints, as by sufferings they were known to be his disciples, and by sufferings they were to purchase that eternal weight of glory prepared for all that suffer patiently and joyfully for God’s sake.”

“Translate as Greek, "And that (Phi 1:13) most of the brethren in the Lord," &c. "In the Lord," distinguishes them from "brethren after the flesh," Jewish fellow countrymen. ELLICOTT translates, "Trusting in the Lord." by my bonds--encouraged by my patience in bearing my bonds. much more bold--Translate as Greek, "are more abundantly bold."”
