“How is it "for them?" How is it "their glory?" It is because God so loved them, as to give even the Son for them, and to afflict His servants for them: for it was in order that they might attain so many blessings, that Paul was in prison. Surely this was from God's exceeding love towards them: it is what God also saith concerning the Prophets, "I have slain them by the words of my mouth." But how was it that they fainted, when another was afflicted? He means, they were troubled, were distressed. This also he says when writing to the Thessalonians, "that no man be moved by these afflictions." For not only ought we not to grieve, but we ought even to rejoice. If ye find consolation in the forewarning, we tell you beforehand that here we have tribulation. And why pray? Because thus hath the Lord ordered.”

“After the Apostle has treated of the dignity of his office, which pertains to his condition, here he consequently treats of those things which pertain to his affliction, namely, of his sufferings. Concerning this he does two things. First, he exhorts them not to be troubled on account of his tribulations, but to have patience; second, because divine help is necessary for a man not to be troubled, he sets forth a prayer beforehand, that they may fulfill this through divine grace, at the place "for this cause," etc. He says therefore first: from the greatness of my office and its firmness, which I have through faith in Christ, it happens that I suffer tribulations; but they do not trouble me, nor can they tear me away from Christ. Romans 8:35: "Who shall separate us from the charity of Christ? Tribulation?" etc.; as if to say: nothing. For which reason I exhort you and ask that you not lose heart in my tribulations, namely, lest on the occasion of my tribulations you fall away entirely from faith and from good works. Hebrews 12:3: "Do not grow weary, fainting in your minds." But I say that you ought not to lose heart, because they are for you, that is, for your benefit. 2 Corinthians 1:6: "Whether we are troubled, it is for your exhortation and salvation; or whether we are comforted, it is for your consolation; or whether we are exhorted, it is for your exhortation and salvation, which works the enduring of the same sufferings which we also suffer, that our hope may be firm for you, knowing that as you are partakers of the sufferings, so shall you be also of the consolation." Or he says "for you," that is, for your testing. Wisdom 3:6: "As gold in the furnace the Lord has tried his elect," etc. "Which is your glory," etc., namely if you do not lose heart, but stand strong in tribulations. For "he who shall persevere unto the end," etc. In another way: "which is your glory," that is, the endurance of our sufferings, is for you unto glory, in this, that God has exposed his apostles and prophets to tribulations and sufferings for the sake of your salvation. Hosea 6:5: "Therefore I have hewn them by the prophets, and I have slain them," etc. 2 Corinthians 1:14: "We are your glory, as you also are ours," etc. Next, when he says "for this cause," etc., he implores help for them through prayer, that they may profit through his exhortation. And first he sets forth the prayer; second, as though assured of being heard, he gives thanks, at the place "now to him who is able," etc. Again, the first is divided into three, because first he sets forth the object of the prayer; second, the intent of the prayer, at the place "that he would grant you, according to the riches," etc.; third, the fruit of the prayer, at the place "that you may be able to comprehend," etc. Now prayer is rendered able to be heard through humility. Psalm 101:18: "He has had regard to the prayer of the humble," etc. Ecclesiasticus 35:21: "The prayer of him who humbles himself shall pierce the clouds," etc. And therefore he immediately begins his prayer from humility, saying "for this cause," namely lest you fall away from the faith, "I bend my knees to the Father," etc., which is a sign of humility on account of two things. First, because he who bends the knee, in a certain way makes himself small, and subjects himself to him to whom he bends the knee: hence through this sort of act is shown the recognition of one's own frailty and smallness. Second, because in the knee is the strength of the body. When, therefore, someone bends the knee, he professes the weakness of his own strength. And hence it is that exterior bodily signs are exhibited to God for the conversion and spiritual exercise of the interior soul. In the Prayer of Manasseh: "I bend the knees of my heart," etc. Isaiah 45:23: "To me every knee shall bow," etc. Then he describes the object of the prayer, which is God, and describes him from two things: first from affinity, second from authority. For from affinity we are raised up to pray with confidence. And as to this he says "to the Father of our Lord Jesus Christ," namely of whom we are sons. James 1:17: "Every best gift," etc. Isaiah 63:16: "For you, Lord, are our father," etc. But from authority is confirmed the confidence of obtaining what we ask, because he himself is the one "from whom all paternity in heaven and on earth is named." Here it could be asked whether there is paternity in heaven. It could be said briefly that in heaven, that is, in God or in the divine, there is paternity, which is the principle of all paternity. But this is not asked about at present, because it is known to every believer. But it is asked whether in the heavens, that is, whether in the Angels there is any paternity. To this I say that paternity exists only in living and knowing beings. Now there is a twofold life. One according to act, the other according to potency. Life according to potency is indeed to have the works of life in potency. Hence one who is sleeping, as regards exterior acts, is said to live in potency. But to live according to act is when someone exercises the works of life in act. In this way, not only he who gives the potency of life is the father of him to whom he gives it, but he who gives the act of life can also be called a father. Whoever, therefore, leads someone to some act of life — for instance, to acting well, understanding, willing, loving — can be called his father. 1 Corinthians 4:15: "For though you have ten thousand instructors in Christ, yet not many fathers," etc. Since, therefore, among the Angels one enlightens, perfects, and purges another, and these are hierarchical acts, it is manifest that one Angel is the father of another, just as a teacher is the father of a disciple. But it is doubted whether the paternity which is in the heavens and on earth is derived from the paternity which is in the divine. And it seems that not; because we impose names in this way according as we know the things named; but whatever we know, we know through creatures; therefore the names imposed by us on the things themselves belong more and prior to creatures than to God himself. I respond and say that the name of some thing named by us can be taken in two ways: for it is either expressive, or significative, of a concept of the intellect — because words are marks, or signs of the passions, or of the concepts that are in the soul — and in this way the name is prior in creatures than in God. Or insofar as it is manifestative of the quiddity of the thing named exteriorly, and in this way it is prior in God. Hence this name "paternity," according as it signifies the conception of the intellect of the one naming the thing, is thus found prior in creatures rather than in God, because a creature becomes known to us prior to God; but according as it signifies the very thing named, it is thus prior in God than in us, because certainly every generative power in us is from God. And therefore he says: "from whom all paternity in heaven and on earth is named," as if to say: the paternity which is in the creatures themselves is, as it were, nominal or verbal, but that divine paternity, by which the Father gives the whole nature to the Son, without any imperfection, is true paternity. Next, when he says "that he would grant you," etc., he shows the intent of the prayer. And first he does this; second, he shows by what means he might obtain his purpose, at the place "through his Spirit," etc. He says therefore: I say that I ask that you not lose heart, but stand manfully. Yet I know that you cannot do this of yourselves without the gift of God, and therefore I ask "that he would grant you." James 1:17: "Every best gift," etc. And this indeed "according to the riches of his glory," that is, according to the abundance of his majesty and magnificence. Psalm 111:3: "Glory and riches are in his house." Proverbs 8:18: "With me are riches and glory." Riches, I say, which cause one "to be strengthened with might." Isaiah 40:29: "Who gives strength to the weary, and to those who have no might he multiplies force and strength." And this "in the inner man," because unless a man is strengthened in his interior parts, he is easily overcome by the enemy. Isaiah 9:7: "He shall confirm it and strengthen it in judgment and justice, from henceforth and forever." Then let that interposed clause be taken up again, namely "through the Spirit," in which he shows by what means he can obtain what he asks. For the Spirit himself, who gives strength, is the spirit of fortitude and is the cause of not losing heart in tribulations, whom we obtain through faith, which is most strong: because faith is "the substance of things to be hoped for," that is, it makes the things to be hoped for subsist in us. Hence 1 Peter 5:9: "Whom resist, strong in faith." And therefore he subjoins "that Christ may dwell through faith," and this "in your hearts." 1 Peter 3:15: "But sanctify the Lord Christ in your hearts." By what? I say that not only through faith, which, as a gift, is most strong, but also through charity, which is in the saints. And therefore he adds "rooted and founded in charity." 1 Corinthians 13:7: "It bears all things, believes all things, hopes all things, endures all things; charity never fails." Song of Songs, last chapter: "Love is strong as death." Hence, just as a tree without a root, and a house without a foundation, easily collapses, so a spiritual building, unless it be founded and rooted in charity, cannot endure.”

“Wherefore I desire that ye faint not at my tribulations for you,.... The apostle was a man attended with many tribulations, and great afflictions, which he did not suffer as an evildoer, either from God or men; wherefore he was not ashamed of them, but gloried in them; yea, he took pleasure in them, having much of the presence of God in them; they did not come to him unawares, he always expected them, and was helped to look to the glory which should follow them, the view of which greatly supported him under them; and these tribulations were endured for the sake of the elect, for Christ's body's sake; the church, and among others, for the Ephesians, for the sake of preaching the Gospel among them, and for the confirmation of their faith in it; and yet they were a stumbling to them, they were ready to faint at them; but he desires they would not, since they were on account of the Gospel, which he had such a distinct knowledge of, and so clear a call to; and since they were for their sakes, and since he and they had such nearness of access to God by the faith of Christ, with so much boldness and confidence; and seeing also they turned to their account: which is your glory; meaning either that it was matter of glorying to them, and what they might boast of, that the apostle's afflictions were not for any crime that was found in him, but for preaching the Gospel to them, and that it was an honour to suffer in such a cause; or that their perseverance and constancy in the doctrines of the Gospel, notwithstanding the scandal of the cross, would be an honour to them. Wherefore I desire that ye faint not at my tribulations for you,.... The apostle was a man attended with many tribulations, and great afflictions, which he did not suffer as an evildoer, either from God or men; wherefore he was not ashamed of them, but gloried in them; yea, he took pleasure in them, having much of the presence of God in them; they did not come to him unawares, he always expected them, and was helped to look to the glory which should follow them, the view of which greatly supported him under them; and these tribulations were endured for the sake of the elect, for Christ's body's sake; the church, and among others, for the Ephesians, for the sake of preaching the Gospel among them, and for the confirmation of their faith in it; and yet they were a stumbling to them, they were ready to faint at them; but he desires they would not, since they were on account of the Gospel, which he had such a distinct knowledge of, and so clear a call to; and since they were for their sakes, and since he and they had such nearness of access to God by the faith of Christ, with so much boldness and confidence; and seeing also they turned to their account: which is your glory; meaning either that it was matter of glorying to them, and what they might boast of, that the apostle's afflictions were not for any crime that was found in him, but for preaching the Gospel to them, and that it was an honour to suffer in such a cause; or that their perseverance and constancy in the doctrines of the Gospel, notwithstanding the scandal of the cross, would be an honour to them. Ephesians 3:14 eph 3:14 eph 3:14 eph 3:14For this cause I bow my knees unto the Father,.... That is, pray unto him for the perseverance of the saints; for nothing is more desirable to the ministers of Christ than that; which is the pure gift of God, and is what he has promised, and therefore should be prayed to for it; for what God has designed and promised to his people, he will be sought to; and the apostle's view might be also to stir up these saints to pray for themselves: the gesture he used in prayer was bowing the knees; a man is not tied to any particular gesture or posture in prayer, the main thing is the heart; mere postures and gestures are insignificant things with God; though where the mind is affected, the body will be moved; and this gesture may be expressive of reverence, humility, and submission in prayer: the object he prayed unto is the Father; that is, as follows, of our Lord Jesus; though these words are wanting in the Alexandrian copy, and Ethiopic version, yet are rightly retained in others; for God is the Father of Christ, not by creation, nor adoption, but by generation, being the only begotten of the Father; and as such he is rightly prayed to, since not only Christ prayed to him as such; but he is the Father of his people in and through Christ; and there is no other way of coming to him but by Christ; and all spiritual blessings come though Christ, and from God, as the Father of Christ.”

“I desire that ye faint not - In those primitive times, when there was much persecution, people were in continual danger of falling away from the faith who were not well grounded in it. This the apostle deprecates, and advances a strong reason why they should be firm: "I suffer my present imprisonment on account of demonstrating your privileges, of which the Jews are envious: I bear my afflictions patiently, knowing that what I have advanced is of God, and thus I give ample proof of the sincerity of my own conviction. The sufferings, therefore, of your apostles are honorable to you and to your cause; and far from being any cause why you should faint, or draw back like cowards, in the day of distress, they should be an additional argument to induce you to persevere."”

“"I entreat you not to be dispirited." for you--in your behalf. which is--rather, "which are your glory," namely, inasmuch as showing that God loved you so much, as both to give His Son for you, and to permit His apostles to suffer "tribulations" for you [CHRYSOSTOM] in preaching the Gospel to the Gentiles. See on Eph 3:1, "prisoner for you Gentiles." My tribulations are your spiritual "glory," as your faith is furthered thereby (Co1 4:10).”
