Some, I say, from contention. Here we have a lengthened detail, in which he explains more fully the foregoing statement; for he repeats that there are two classes of men that are stirred up by his bonds to preach Christ -- the one influenced by contention, that is, by depraved affection -- the other by pious zeal, as being desirous to maintain along with him the defense of the gospel. The former, he says, do not preach Christ purely, because it was not a right zeal. [1] For the term does not apply to doctrine, because it is possible that the man who teaches most purely, may, nevertheless, not be of a sincere mind. [2] Now, that this impurity was in the mind, and did not shew itself in doctrine, may be inferred from the context. Paul assuredly would have felt no pleasure in seeing the gospel corrupted; yet he declares that he rejoices in the preaching of those persons, while it was not simple or sincere. It is asked, however, how such preaching could be injurious to him? I answer, that many occasions are unknown to us, inasmuch as we are not acquainted with the circumstances of the times. It is asked farther, "Since the gospel cannot be preached but by those that understand it, what motive induced those persons to persecute the doctrine of which they approved?" I answer, that ambition is blind, nay, it is a furious beast. Hence it is not to be wondered if false brethren snatch a weapon from the gospel for harassing good and pious pastors. [3] Paul, assuredly, says nothing here [4] of which I have not myself had experience. For there are living at this very day those who have preached the gospel with no other design, than that they might gratify the rage of the wicked by persecuting pious pastors. As to Paul's enemies, it is of importance to observe, if they were Jews, how mad their hatred was, so as even to forget on what account they hated him. For while they made it their aim to destroy him, they exerted themselves to promote the gospel, on account of which they were hostile to him; but they imagined, no doubt, that the cause of Christ would stand or fall [5] in the person of one individual. If, however, there were envious persons, [6] who were thus hurried away by ambition, we ought to acknowledge the wonderful goodness of God, who, notwithstanding, gave such a prosperous issue to their depraved affections.

The one preach Christ of contention - So as to form parties, and to produce strifes among his professed followers.
Not sincerely - Not "purely" - ἁγνῶς hagnōs - not with pure motives or intentions. Their real aim is not to preach Christ, but to produce difficulty, and to stir up strife. They are ambitious people, and they have no real regard for the welfare of the church and the honor of religion.
Supposing to add affliction to my bonds - To make my trial the greater. How they did this is unknown. Perhaps they were those who were strongly imbued with Jewish notions, and who felt that his course tended to diminish respect for the law of Moses, and who now took this opportunity to promote their views, knowing that this would be particularly painful to him when he was not at liberty to meet them openly, and to defend his own opinions. It is possible also that they may have urged that Paul himself had met with a signal reproof for the course which he had taken, and, as a consequence, was now thrown into chains. Bloomfield suggests that it was the opinion of many of the ancient expositors that they endeavored to do this by so preaching as to excite the fury of the multitude or the rulers against Paul, and to produce increased severity in his punishment. But the way in which they did this is unknown, and conjecture is altogether useless.

Preach Christ of contention - The Judaizing teachers, they also preach Christ; they acknowledge that Jesus is the Christ or promised Messiah, and preach him as such.
Not sincerely - Ουχ ἁγνως· Not chastely, garbling the Gospel; not speaking the whole truth, but just what served their purpose; and at the same time they denounced the apostle as an enemy to the Divine institutions, because he spoke against circumcision.

The one preach Christ of contention, not (l) sincerely, supposing to add affliction to my bonds:
(l) Not with a pure mind: for otherwise their doctrine was pure.

The one preach Christ of contention,.... That is, those that preached of envy and strife, an not of good will to Christ, to the Gospel, to the souls of men, or to the apostle; and though they preached Christ, yet
not sincerely or "purely"; not but that they delivered the sincere milk of the word, and preached the pure Gospel of Christ, without any mixture and adulteration; but then they did not preach it with a sincere heart, and a pure intention; for this respects not the doctrine they preached, but their views in it, which were not honest and upright; they did not preach Christ from a principle of love to his person, and from an inward experience of the power of his Gospel, and a zealous affection for it, and firm attachment to it, and with a view to the glory of God, the honour of Christ, and the good of immortal souls; but were influenced by avarice, ambition, and envy: they had very evil designs upon the apostle,
supposing to add affliction to my bonds; imagining that by their free and bold way of preaching Christ openly in the city without control, and with impunity, it might be thought that the apostle did not lie in bonds for preaching Christ, but for some other crime; or otherwise why were not they laid hold on and put under confinement also? or thinking that by such numbers of them frequently preaching Christ about the city, it would either incense and stir up the Jews, Paul's accusers, to prosecute him more vigorously; or excite Nero to take more cognizance of his case, and either more closely confine him, or hasten the bringing his cause to a hearing, and him to punishment, as the ringleader of this sect, to the terror of others; but this they could not do without exposing themselves to great danger, unless they were determined to recant, as soon as they should be taken up; wherefore it should rather seem that their view was in preaching Christ to carry away the glory of it from the apostle, and take it to themselves; and fancying that he was a man of the same cast with them, desirous of vain glory, they thought it would afflict and distress him, he being in bonds, and not at liberty to exert himself, and make use of his superior gifts and abilities; but in this they were mistaken, he was so far from being made uneasy hereby, that he rejoiced at the preaching of Christ, let their intentions be what they would; and therefore he does not say that they did add affliction to his bonds; but they "supposed", or thought, that the method they took would do it.

The oldest manuscripts transpose these verses, and read, "These (last) indeed out of love (to Christ and me), knowing (the opposite of 'thinking' below) that I am set (that is, appointed by God, 1-Thessalonians 3:3) for the defense of the Gospel (Philippians 1:7, not on my own account). But the others out of contention (or rather, 'a factious spirit'; 'cabal'; a spirit of intrigue, using unscrupulous means to compass their end; 'self-seeking' [ALFORD]) proclaim (the Greek is not the same as that for 'preach,' but, 'announce') Christ, not sincerely (answering to 'but of a spirit of intrigue,' or 'self-seeking'). Literally, 'not purely'; not with a pure intention; the Jewish leaven they tried to introduce was in order to glorify themselves (Galatians 6:12-13; however, see on Philippians 1:18), thinking (but in vain) to raise up (so the oldest manuscripts read) tribulation to my bonds." Their thought was, that taking the opportunity of my being laid aside, they would exalt themselves by their Judaizing preaching, and depreciate me and my preaching, and so cause me trouble of spirit in my bonds; they thought that I, like themselves, sought my own glory, and so would be mortified at their success over mine. But they are utterly mistaken; "I rejoice" at it (Philippians 1:18), so far am I from being troubled at it.
