“For just as it is not possible to bind a sunbeam or to shut it up within the house, so neither can the preaching of the word be bound. And what was much more, when the teacher was bound, the word flew abroad. He inhabited the prison, and yet his teaching winged its way everywhere throughout the world!”
“Any cloud passing over our skies may from time to time make us gloomy. But Paul's heart had no such storms sweeping over it. Or better, there did sweep over him, and often, many storms, but his day was not darkened. Rather in the midst of the temptations and dangers the light shone out. Thus when bound with his chain he kept exclaiming, "The word of God is not bound." Thus continually by means of that tongue the Word was sending forth its rays.”

“For what could be better than those bonds which always in his Epistles he prefers to all things else, saying, "Paul, a prisoner of Jesus Christ:" and again, "On this account I am bound with this chain, but the word of God is not bound;" and, "Even unto bonds, as an evil-doer." The punishment was twofold. For if indeed he had been so bound, as with a view to his good, the thing would have carried with it some consolation: but now he is bound both "as an evil-doer," and as with a view to very ill consequences; yet for none of these things cared he.”

“"Wherein I suffer trouble," he says, "as an evil-doer, even unto bonds." Again he introduces consolation and encouragement from himself, and he prepares his hearer's mind with these two things; first, that he should know him to endure hardness; and, secondly, that he did not so but for a useful purpose, for in this case he will gain, in the other will even suffer harm. For what advantage is it, that you can show that a Teacher has exposed himself to hardship, but not for any useful purpose? But if it is for any benefit, if for the profit of those who are taught, then it is worthy of admiration. "But the word of God is not bound." That is, if we were soldiers of this world, and waged an earthly warfare, the chains that confine our hands would avail. But now God has made us such that nothing can subdue us. For our hands are bound, but not our tongue, since nothing can bind the tongue but cowardice and unbelief alone; and where these are not, though you fasten chains upon us, the preaching of the Gospel is not bound. If indeed you bind a husbandman, you prevent his sowing, for he sows with his hand: but if you bind a Teacher, you hinder not the word, for it is sown with his tongue, not with his hand. Our word therefore is not subjected to bonds. For though we are bound, that is free, and runs its course. How? Because though bound, behold, we preach. This is for the encouragement of those that are free. For if we that are bound preach, much more does it behoove you that are loose to do so. You have heard that I suffer these things, as an evil-doer. Be not dejected. For it is a great wonder, that being bound I do the work of those that are free, that being bound I overcome all, that being bound I prevail over those that bound me. For it is the word of God, not ours. Human chains cannot bind the word of God.”

“Above, the preparation for martyrdom was set forth; here the exhortation to it is set forth, and first he sets forth in advance the example of the reward; second, the example of martyrdom, at in which I labor; third, he shows the connection of the reward to martyrdom, at faithful is the saying. For the reward of the precious death of martyrdom is the glorious resurrection, the example of which preceded in Christ our head. And therefore he says be mindful, etc., as if to say: our Lord Jesus Christ — supply: keep him in mind against tribulations. Prov. 3:6: In all your ways think on him, and he will direct your steps. For there are many things to be thought about in him, but especially the resurrection. To this all things are ordered, and especially the whole state of the Christian religion. Rom. 10:9: If you confess with your mouth the Lord Jesus, and believe in your heart that God raised him from the dead, you will be saved. And note that he says raised up, because although the Father raised him, yet he also rose by his own power, and he is the first of those rising, 1 Cor. 15:20. But because he rose according to human nature, and died, of the seed of David. Rom. 1:3: who was made to him of the seed of David according to the flesh, et cetera. According to my Gospel, that is, preached by me. 1 Cor. 15:1: But I make known to you the Gospel which I preached to you. He who preaches the Gospel is a minister of the Gospel, just as he who baptizes is a minister of Baptism. Yet it cannot be said "my Baptism," but "my Gospel" can be said thus. And this is so because exhortation and solicitude contribute much. Then, when he says in which I labor, he shows himself as an example of martyrdom, and first its punishment; second its cause, at therefore all things. Now he shows three things to be in the punishment, namely bitterness, reproach, and constancy. Bitterness, when he says in which, namely in preaching the Gospel, or for which I labor, that is, I am afflicted, and this even unto bonds, because when he wrote this epistle, he was at Rome in bonds. Eph., last chapter: the ministry of the Gospel, for which I act as ambassador in a chain. Reproach as regards unbelievers, when he says as an evildoer. For Christians then were reputed the worst. Lc. 9: Blessed will you be when men hate you, and separate you, and reproach you, et cetera. Christ too was condemned, as an evildoer. Is. 53:12: and he was reputed with the wicked. But he shows constancy, when he says but the word of God, et cetera. For although the body is bound, yet the word of God is not bound, because preaching came from the will of the apostle, which is free, especially on account of the efficacy of charity, which fears nothing. Rom. 8:38: For I am certain that neither death, nor life, et cetera. Because, as it is said in 1 Jn. 3:20, God is greater than our heart. And it is said that, existing in bonds, he converted many. Then, when he says therefore I endure all things, he shows the cause, because it is not the punishment that makes a martyr, but the cause. Now the cause of martyrdom is twofold, namely for the sake of divine honor, and the salvation of one's neighbor. For the sake of God indeed, because Rom. 8:36: for your sake we are put to death all the day long. For the salvation of neighbors, because he says here for the sake of the elect. Jn. 15:13: Greater love has no one, than that someone lay down his life for his friends. 1 Jn. 3:16: because he laid down his life for us, and we ought to lay down our lives for the brethren. And he says for the sake of the elect, because whatever good things happen, they redound especially to the good of the elect, not of the reprobate. And how? That they too may obtain salvation. But is the Passion of Christ sufficient? It must be said that it is, effectively, but the passion of the apostle was expedient in two ways. First, because it gave an example of persisting in the faith; second, because the faith was confirmed, and from this they were led to salvation. And this in Christ, that is, which comes to us through him. Matt. 1:21: for he will save the people from their sins. And this not only salvation, present in grace, but also with heavenly glory. Matt. ch. 5:12: your reward is abundant in the heavens. Then, when he says faithful is the saying, he sets forth the connection of the reward to the merit of martyrdom. And first he sets forth the attestation; second, the consequence, at for if we have died together; third, he confirms it by testimony, at these things put in remembrance. He says therefore faithful is the saying, that is, the word which I shall say is faithful. Apoc., last chapter: these words are most faithful, et cetera. Then, when he says for if, et cetera, he sets forth the consequence. And first concerning the reward of the good; second concerning the punishment of the evil, at if we deny. In the reward of the good there are two things, namely restoration through the resurrection, and the addition of glory to which they will rise. And therefore first he shows that through Christ one comes to the restoration of life; second that through him one comes to the resurrection, at if we endure. He says therefore if we have died together, namely with Christ, and this through the reception of the sacrament in Baptism. Rom. 6:4: for we are buried together with him through Baptism into death. Likewise through penance, by mortifying ourselves. Gal. 6:24: those who are Christ's have crucified their flesh with the vices and lusts. Likewise by dying for the confession of truth, just as Christ also did. Ps. 115:15: Precious in the sight of the Lord is the death of his saints. If therefore we have died together, we shall also live together, that is, just as he rose, so shall we too. Rom. 6:5: If we have been planted together with the likeness of his death, we shall be also of his resurrection. Then he treats of the glory, which the saints merit through the ignominy of death. Lc., last chapter: was it not necessary that Christ should suffer these things? And therefore he says if we endure, namely afflictions and reproaches patiently, we shall reign together, that is, we shall arrive at the kingdom together with him. Matt. 5:10: Blessed are those who persecution, et cetera. Then, when he says if we deny, he shows the consequence as regards punishments. Now one can sin against the faith in two ways: first, by denying it outwardly; second, by laying it aside inwardly. As to the first, he says if we deny, namely before others, he will deny us in judgment. Matt. 25:12: Amen I say to you, I do not know you. To deny is not to acknowledge them to be of his own sheep. As to the second, he says if we do not believe, that is, if we cast faith from the heart, he remains faithful, that is, he holds to his own faithfulness. Hence he remains faithful in his faith, because faith is nothing other than participation in, or adherence to, the truth. But he himself is the very truth, which cannot deny itself. Therefore he is not omnipotent. I respond. From this he is omnipotent, that he cannot deny himself. For to be able to fail pertains rather to impotence, because that something should fail from its own being is through a weakness of its own power. But for Christ to deny himself is to fail from himself; this very fact, therefore, that he cannot deny himself, is the reason of perfect power. Hence sin does not fall upon him, as has been said, nor can he deny his power and his justice without punishing. Matt., last chapter: but he who does not believe will be condemned. But can God not remit the punishment to someone? He can indeed according to the order of his wisdom, but against the order of wisdom and justice, he cannot. Then, when he says these things put in remembrance, et cetera, he confirms it by testimony; as if to say: I admonish along with others, that you may always keep it in your heart, testifying before God, that is, bringing forward as witness him before whom I speak. Then, when he says do not with words, he shows how he resists unbelievers, because first he sets forth in advance the manner of resisting; second he shows what the things are which he resists, at profane. Likewise, first he excludes the undue manner of resisting; second he sets forth the due manner, at diligently. Concerning the first, first he excludes the undue manner; second he assigns the reason, at to nothing. He says therefore do not contend with words. Contention implies a contending in words. It can therefore be understood in two ways, because one speaking with acrimony is depraved in two ways. In one way, if by this one inclines to the favor of falsity, as when someone attacks the truth with a confident clamor. In another way, on account of disorder, as when one uses acrimony either beyond the due measure, or contrary to the quality of the person. But if it is done moderately, and with due circumstances, and on behalf of the truth, it is not a sin. And thus in rhetoric it is one instrument of exhortation. Yet in sacred Scripture it is taken according as it implies disorder. 1 Cor. 11:16: If anyone seems to be contentious among you, we have no such custom, nor does the Church of God. And he says with words, because some dispute only with words of reproach. And this properly is to contend. If this is done not with words only but with true reasons, this is to dispute, not to contend. Then, when he says it is useful for nothing, he shows the reason for the teaching. For moderate disputation, when it is done with reason, is useful for instruction; but when it is with words only, then it is litigious. Therefore he says but to the subverting, and this in two ways: in one way, while what is certain comes into doubt; in another way, because the hearers are scandalized. Prov. 14:23: Where there are many words, there is frequently poverty; hence Jas. 3:16: Where there is envy and contention, there is inconstancy and every wicked work. But should one not dispute about the faith before the people without contention? I respond. A distinction must be made, on the part of the hearers, because either they are being solicited by unbelievers, and then public disputation is useful: because through this the simple are made more instructed when they see those who err refuted. But if they are not being solicited by unbelievers, then disputation is not useful, but dangerous. Likewise a distinction must be made on the part of the one disputing, because if the disputant is prudent, so that he clearly refutes the adversary, then he ought to dispute publicly; but if not, in no way. Then, when he says diligently take heed to yourself, he sets forth the due manner of resisting. And first as regards right intention; second as regards right action; third as regards right doctrine. For he who wishes to dispute must first examine his own intention, whether he is moved by good zeal. Therefore he says to show himself approved to God, who indeed tests the heart. 2 Cor. 10:18: For it is not he who commends himself that is approved, but he whom God commends. Ps. 16:3: You have proved my heart, and visited it by night. Likewise, that he confirm through his works the doctrine which he preaches with his mouth, which unless he does, he is worthy of confusion. Hence he says a workman that need not be ashamed, as if to say: do these things, and thus you will not be put to confusion. Likewise, that he rightly handle the word of truth, teaching things true and useful to the hearers. Hence he adds rightly handling the word of truth, not seeking gain and glory. 2 Cor. 2:17: We are not like many, adulterating the word of God, but out of sincerity, as from God, in the sight of God, we speak in Christ.”

“Wherein I suffer trouble as an evildoer,.... As a malefactor, as if guilty of some capital crime; an enemy to the law of Moses, a pestilent fellow, a mover of sedition everywhere, and a ringleader of the sect of the Nazarenes, Act 24:5. The Ethiopic version renders it, "as a thief". The "trouble" he suffered were reproaches, persecutions, whipping, beating, stoning, imprisonment: for he adds, even unto bonds; for he was now a prisoner, and in chains; nor was it the first time, he was in prisons frequent; and all this for the sake of the Gospel, which he preached, concerning the incarnation, death, and resurrection of Christ: but the word of God is not bound; for the apostle, while a prisoner at Rome, had the liberty of dwelling by himself, in his own hired house, though held in chains, and guarded by a soldier, and of receiving his friends, and of preaching the Gospel to as many as would come to hear him, Act 28:16 as well as of sending letters to the churches; for several of his epistles were written by him when a prisoner, as those to the Ephesians, Philippians, and Colossians; and this to Timothy, and also that to Philemon: so that the Gospel was not restrained, or the apostle restrained from publishing it, both by word of mouth, and by writing; which was a great support to him under his troubles. Moreover, the Gospel was the more spread through the bonds of the apostle, and met with great success; it became known in Caesar's palace, and was the means of the conversion of some of his household; and many of the brethren, through his bonds, became bolder to preach the Gospel of Christ; so that it had a free course, and was glorified: and sometimes so it is, that persecution is a means of the greater spread of the Gospel; which was an effect that followed upon the persecution raised against the church at Jerusalem, upon the death of Stephen, Act 8:1. And indeed, when God opens an effectual door, none can shut it, though there be many adversaries; and when he gives the word a commission, there is no stopping it; when it comes in power, it bears down all before it; it cannot be fettered and bound by men, though men may be fettered and bound for the sake of it.”

“Wherein--in proclaiming which Gospel. suffer trouble--literally, "evil." I am a sufferer of evil as though I were a doer of evil. bonds-- (Ti2 1:16). word . . . not bound--Though my person is bound, my tongue and my pen are not (Ti2 4:17; Act 28:31). Or he alludes not merely to his own proclamation of the Gospel, though in chains, but to the freedom of its circulation by others, even though his power of circulating it is now prescribed (Phi 1:18). He also hints to Timothy that he being free ought to be the more earnest in the service of it.”
