“Ver. 7. "Even as ye learned of Epaphras our beloved fellow-servant." He, it is probable, had preached there. "Ye learned" the Gospel. Then to show the trust-worthiness of the man, he says, "our fellow servant." "Who is a faithful minister of Christ on your behalf; who also declared unto us your love in the Spirit." Doubt not, he saith, of the hope which is to come: ye see that the world is being converted. And what need to allege the cases of others? what happened in your own is even independently a sufficient ground for belief, for, "ye knew the grace of God in truth:" that is, in works. So that these two things, viz. the belief of all, and your own too, confirm the things that are to come. Nor was the fact one thing, and what Epaphras said, another. "Who is," saith he, "faithful," that is, true. How, "a minister on your behalf"? In that he had gone to him. "Who also declared to us," saith he, "your love in the Spirit," that is, the spiritual love ye bear us. If this man be the minister of Christ; how say ye, that you approach God by angels? "Who also declared unto us," saith he, "your love in the Spirit." For this love is wonderful and steadfast; all other has but the name. And there are some persons who are not of this kind, but such is not friendship, wherefore also it is easily dissolved.”

“Here, coming to the matter at hand, he begins the epistolary treatise. And first he commends the truth of the Gospel; second he protects the truth of this state against contrary things, in chapter II, there: for I would have you know. Concerning the first he does two things. First he commends the truth of the evangelical faith; second the author of this state, there: who is the image. Likewise the first is divided into two, because first he gives thanks for the benefits specially shown to the Colossians; second for those shown generally to the Church, there: giving thanks. Concerning the first he does two things, because first he commends the giving of thanks to God for these things; second he shows the matter of the prayer, there: hearing. Again the first is divided into two, because first he sets forth the giving of thanks; second the prayer, there: praying. He says therefore: we give thanks to God, the author of graces. I Thess. ult.: in all things give thanks. And this always, for things past and future. For although we cannot pray continuously in act, yet always, from the habit of charity, we ought to pray. I Thess. ult.: pray without ceasing. Lk. XVIII, 1: one ought always to pray. Then the matter is set down, first of the giving of thanks, second of the prayer, there: therefore we also. Concerning the first he first recalls their goods, second how they obtained these, there: which you heard. Our good is principally in faith, hope and charity: for through faith we have knowledge of God, through hope we are lifted up to him, but by charity we are united to him. I Cor. XIII, v. 13: but now there remain faith, hope, charity, these three, etc. And therefore concerning these three he gives thanks, first that they have faith. For he himself had not preached to them, but a certain disciple named Epaphras, and afterward Archippus. And therefore he says hearing the faith, which is the beginning of the spiritual life. Hab. II, 4: my just one lives by faith. Hebr. XI, 6: he who comes to God must believe, etc. But this faith without love working is dead, as is said in Jas. II, 17. And therefore there must be present a love that works. Gal. ult.: in Christ Jesus neither circumcision avails anything, nor uncircumcision, but a new creature. And therefore he said and the love which you have, etc. Now there is a certain love of charity and a certain worldly love, but worldly love does not extend to all, because such love is toward those with whom there is a fellowship, which is the cause of the love, and this cause in worldly love does not hold toward all, but is only with kinsmen and worldly people, but the love of charity extends to all. And therefore he says toward all. For even if sinners are loved through charity, this is that they may at some time be holy. I Jo. III, 14: we know that we have passed from death to life, because we love the brethren. Likewise the love of the world has its fruit in this world, but charity has it in eternal life. And therefore third he adds concerning hope, saying because of the hope which is laid up, that is, because of eternal glory, which is therefore called hope, because it is kept for certain. Job XIX, 27: this my hope is laid up in my bosom. Then when he says which before you heard, he shows how they obtained these things. And first he commends the evangelical doctrine, second the ministry, there: as you learned. Likewise first he commends the doctrine from its truth; second from its spreading abroad, there: which has come; third from its fruitfulness, there: and bears fruit. He says therefore which you heard, namely the hope, or the thing hoped for. And this in the word of the truth of the Gospel. For this surpasses all things. I Cor. II, 9: neither has eye seen, nor ear heard, nor has it entered into the heart of man, etc. And therefore God reveals it. Matth. III, 2: do penance, for the kingdom of heaven will draw near. But this is a true hope, and not vain (as when the one promising is a liar), because it is in the word of truth. Jo. XVII, 17: your word is truth. Then when he says which has come, the doctrine of Christ is commended from its spreading abroad, because it has not only come to you, but in the whole world. Ps. XVIII, 4: their sound has gone out into all the earth, etc. Matth. XXIV, 14: this Gospel of the kingdom must be preached in the whole world, and then will be the consummation. But how is it not yet the consummation, since it has been preached in the whole world? I answer. Some say that the Gospel of Christ is not the Gospel of the kingdom. But this is false, because the Lord calls this the Gospel of the kingdom. But it must be said, according to Chrysostom, that while the apostles were still living, the Gospel of Christ was spread through the whole world, at least as to fame, which is exceedingly marvelous, that in forty years the doctrine of Christ should have grown so much. And thus he says in the whole world, as to fame, and then will be the consummation, that is, the destruction of Jerusalem. But according to Augustine this is not true, because in his own time there were still some peoples among whom the Church did not yet exist. And therefore he himself says this is to be understood as to when it will be preached, so that when the Church will have been founded among all peoples, although some are believers, some not, then will be the end; and this not in the time of the apostles, but around the end of the world: and thus when it is said here in the whole world, the apostle speaks of the future as of the present on account of the certainty of the outcome. Ps. XVIII, 4: their sound has gone out into all the earth, etc. It can, however, be said that according to fame it has been spread through the whole world, but not according to foundation. Then he commends the doctrine of Christ as to its fruit through good works, there: and bears fruit. Eccli. XXIV, 23: my flowers are the fruit of honor and honesty, etc. Matth. XIII, v. 8: it brings forth fruit, and yields some a hundredfold, some sixtyfold, some thirtyfold. And it grows, namely in the multitude of believers. Act. II, 47: but the Lord increased daily those who were being saved, together. And this was of great power, because as in you, so also in others. You have heard the preaching, and you have known it by approving. Consequently he commends the ministry in three ways. First by comparison to himself; second by comparison to them; third as to both. He says therefore: you have been taught through the Gospel, as you learned from Epaphras our fellow servant. Apoc. ult.: I am your fellow servant, and of your brethren. Who is a faithful minister, namely not seeking the things that are his own. I Cor. c. IV, 1: so let a man regard us as ministers of Christ, and dispensers of the mysteries of God, etc. Who is faithful, namely a mediator between the apostle and these. Who also has made manifest, that is, signified, etc.”

“Who also declared unto us your love in the Spirit. Not only their love to God, and Christ, and to all the saints, which is before mentioned, but their love to the apostle; though they had only heard of him, and of his great capacity for, and faithfulness and usefulness in preaching of the Gospel, which had greatly endeared him to them. This, he says, was in the Spirit; it was spiritual love, to distinguish it from a carnal and worldly one; they loved him for the spiritual grace that was in him, the spiritual gifts bestowed on him, the spiritual service he was engaged in, and the spiritual usefulness he was of: or they loved him in, and with their spirits, with all their hearts, sincerely, and without dissimulation; and though they had never seen him in the flesh, yet being, as it were, present with him in spirit, their affections were knit unto him: or this their love was "in the Holy Spirit", as the Ethiopic version reads it; it was a fruit of the Spirit of God, which he had implanted in their hearts in regeneration, as is also love to God, and likewise to Christ. Who also declared unto us your love in the Spirit. Not only their love to God, and Christ, and to all the saints, which is before mentioned, but their love to the apostle; though they had only heard of him, and of his great capacity for, and faithfulness and usefulness in preaching of the Gospel, which had greatly endeared him to them. This, he says, was in the Spirit; it was spiritual love, to distinguish it from a carnal and worldly one; they loved him for the spiritual grace that was in him, the spiritual gifts bestowed on him, the spiritual service he was engaged in, and the spiritual usefulness he was of: or they loved him in, and with their spirits, with all their hearts, sincerely, and without dissimulation; and though they had never seen him in the flesh, yet being, as it were, present with him in spirit, their affections were knit unto him: or this their love was "in the Holy Spirit", as the Ethiopic version reads it; it was a fruit of the Spirit of God, which he had implanted in their hearts in regeneration, as is also love to God, and likewise to Christ. Colossians 1:9 col 1:9 col 1:9 col 1:9For this cause we also,.... Not merely for their love to the apostle, and the rest that were with him; which sense is too much contracted, and carries some appearance of meanness and selfishness; but because of their faith in Christ, their love to all the saints, and the good hope they had of eternal happiness; and because they had heard the Gospel, and truly knew it, and sincerely professed it: therefore, since the day we heard it, do not cease to pray for you, and to desire; which shows that the apostles prayed without ceasing; not that they were every moment praying, without intermission, but that they were frequent and constant every day at the throne of grace; and as often as they were there, they were mindful of these Colossians, even ever since they heard of their reception of the Gospel, of their profession of it, and of the fruit it brought forth in them; and in their petitions "prayed" and "desired", earnestly and importunately entreated God on their behalf: that ye might he filled with the knowledge of his will; the will "of God", as the Syriac version reads it, by which is meant, not the secret will of God, according to the counsel of which he does all things in nature, providence, and grace, but his revealed will; and that either as it is signified in the law, which declares the good, and perfect, and acceptable will of God, relating to what he would have done, or avoided by his creatures; or rather, as it is exhibited in the Gospel, which contains the will of God respecting the salvation of his chosen ones; as that it is his will that Christ should obtain eternal redemption for them, to do which he voluntarily substituted himself in their room, came into this world, and has accomplished it; and that all those that are redeemed by Christ should be regenerated by the Spirit; and that whoever sees the Son, and believes in him, should not perish, but have everlasting life; as also, that all those whom he has chosen in Christ, and given to him, and he has redeemed by his blood, and who are sanctified by his Spirit, none of them should be lost, but that they should be all saved with an everlasting salvation. Now the apostle does, not pray that they might have a "knowledge" of this will of God, for some knowledge of it they had already; they had heard of the hope laid up in heaven, in the truth of the word of the Gospel; they had not only had the external, revelation, and had heard the Gospel outwardly preached, but they had known truly the grace of God; and therefore what he asks for is, that they might be "filled" with the knowledge of it; which supposes that they had knowledge, but it was not full and complete; it was imperfect, as is the knowledge of the best of saints in this life; and that they might have a larger measure of it, and such a fulness of it as they were capable of in the present state, and not such an one as the saints will have in heaven, when they shall know even as they are known. He adds, in all wisdom and spiritual understanding; his meaning is, that they might be led into all the wisdom of God, which is so largely displayed in the revelation of his will concerning the salvation of his people, which is made in the Gospel; which is the manifold wisdom of God, wherein he has abounded in all wisdom and prudence; and contains such a scheme of things, so wisely contrived and formed, that angels desire to look into it; and that they might have a "spiritual understanding" of the mysteries of grace, without which they cannot be discerned to spiritual advantage, nor indeed without the spirit of wisdom and revelation in the knowledge of them: and the Ethiopic version renders it, by "the prudence of the Holy Ghost": who searches the deep things of God, and reveals them to the saints, and improves and increases their spiritual and experimental knowledge of them, which is what is here intended.”

“Your love in the Spirit - So we preached, and so ye believed. The heavenly flame in the heart of this minister communicated itself to those who heard him; it was like priest like people. They enjoyed a spiritual, energetic ministry, and they were a spiritual people; they had a loving spirit, and love through the Spirit of God which dwelt in them. And of this love of theirs in the Spirit, and particularly towards the apostle, Epaphras gave full proof, not only by describing to the apostle the affection they felt for him, but in presenting to him those supplies which their love to him caused them to furnish.”

“Your love. Your charity for all men, founded on the love of God. Others understand it of the affection which they had for St. Paul. (St. Chrysostom)”

“your love-- (Col 1:4); "to all the saints." in the Spirit--the sphere or element IN which alone true love is found; as distinguished from the state of those "in the flesh" (Rom 8:9). Yet even they needed to be stirred up to greater love (Col 3:12-14). Love is the first and chief fruit of the Spirit (Gal 5:22).”
