16 Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord.
[AD 215] Clement of Alexandria on Colossians 3:16
For "if thou shalt love the Lord try God "and then "thy neighbour "let its first manifestation be towards God in thanksgiving and psalmody, and the second toward our neighbour in decorous fellowship. For says the apostle, "Let the Word of the Lord dwell in you richly.".
For the psalm is a melodious and sober blessing. The apostle calls the psalm "a spiritual song."

[AD 220] Tertullian on Colossians 3:16
Together they pray, together prostrate themselves, together perform their fasts; mutually teaching, mutually exhorting, mutually sustaining.

[AD 220] Tertullian on Colossians 3:16
Alms (are given) without (danger of ensuing) torment; sacrifices (attended) without scruple; daily diligence (discharged) without impediment: (there is) no stealthy signing, no trembling greeting, no mute benediction. Between the two echo psalms and hymns; and they mutually challenge each other which shall better chant to their Lord.

[AD 258] Cyprian on Colossians 3:16
Let the faithful Christian, I say, devote himself to the sacred Scriptures, and there he shall find worthy exhibitions for his faith. He will see God establishing His world, and making not only the other animals, but that marvellous and better fabric of man. He will gaze upon the world in its delightfulness, righteous shipwrecks, the rewards of the good, and the punIshments of the impious, seas drained dry by a people, and again from the rock seas spread out by a people. He will behold harvests descending from heaven, not pressed in by the plough; rivers with their hosts of waters bridled in, exhibiting dry crossings. He will behold in some cases faith struggling with the flame, wild beasts overcome by devotion and soothed into gentleness. He will look also upon souls brought back even from death. Moreover, he will consider the marvellous souls brought back to the life of bodies which themselves were already consumed. And in all these things he will see a still greater exhibition-that devil who had triumphed over the whole world lying prostrate under the feet of Christ. How honourable is this exhibition, brethren! how delightful, how needful ever to gaze upon one's hope, and to open our eyes to one's salvation! This is a spectacle which is beheld even when sight is lost. This is an exhibition which is given by neither praetor nor consul, but by Him who is alone and above all things, and before all things, yea, and of whom are all things, the Father of our Lord Jesus Christ, to whom be glory and honour for ever and ever.

[AD 407] John Chrysostom on Colossians 3:16
Having exhorted them to be thankful, he shows also the way, that, of which I have lately discoursed to you. And what saith he? "Let the word of Christ dwell in you richly"; or rather not this way alone, but another also. For I indeed said that we ought to reckon up those who have suffered things more terrible, and those who have undergone sufferings more grievous than ours, and to give thanks that such have not fallen to our lot; but what saith he? "Let the word of Christ dwell in you"; that is, the teaching, the doctrines, the exhortation, wherein He says, that the present life is nothing, nor yet its good things. If we know this, we shall yield to no hardships whatever. "Let it dwell in you," he saith, "richly," not simply dwell, but with great abundance. Hearken ye, as many as are worldly, and have the charge of wife and children; how to you too he commits especially the reading of the Scriptures and that not to be done lightly, nor in any sort of way, but with much earnestness. For as the rich in money can bear fine and damages, so he that is rich in the doctrines of philosophy will bear not poverty only, but all calamities also easily, yea, more easily than that one. For as for him, by discharging the fine, the man who is rich must needs be impoverished, and found wanting, and if he should often suffer in that way, will no longer be able to bear it, but in this case it is not so; for we do not even expend our wholesome thoughts when it is necessary for us to bear aught we would not choose, but they abide with us continually. And mark the wisdom of this blessed man. He said not, "Let the word of Christ" be in you, simply, but what? "dwell in you," and "richly."

[AD 407] John Chrysostom on Colossians 3:16
"In all wisdom, teaching and admonishing one another." "In all," says he. Virtue he calls wisdom, and lowliness of mind is wisdom, and almsgiving, and other such like things, are wisdom; just as the contraries are folly, for cruelty too cometh of folly. Whence in many places it calleth the whole of sin folly. "The fool," saith one, "hath said in his heart, There is no God"; and again, "My wounds stink and are corrupt from the face of my foolishness." For what is more foolish, tell me, than one who indeed wrappeth himself about in his own garments, but regardeth not his brethren that are naked; who feedeth dogs, and careth not that the image of God is famishing; who is merely persuaded that human things are nought, and yet clings to them as if immortal. As then nothing is more foolish than such an one, so is nothing wiser than one that achieveth virtue. For mark; how wise he is, says one. He imparteth of his substance, he is pitiful, he is loving to men, he hath well considered that he beareth a common nature with them; he hath well considered the use of wealth, that it is worthy of no estimation; that one ought to be sparing of bodies that are of kin to one, rather than of wealth. He that is a despiser of glory is wholly wise, for he knoweth human affairs; the knowledge of things divine and human, is philosophy. So then he knoweth what things are divine, and what are human, and from the one he keeps himself, on the other he bestoweth his pains. And he knows how to give thanks also to God in all things, he considers the present life as nothing; therefore he is neither delighted with prosperity, nor grieved with the opposite condition.

[AD 407] John Chrysostom on Colossians 3:16
Tarry not, I entreat, for another to teach thee; thou hast the oracles of God. No man teacheth thee as they; for he indeed oft grudgeth much for vainglory's sake and envy. Hearken, I entreat you, all ye that are careful for this life, and procure books that will be medicines for the soul. If ye will not any other, yet get you at least the New Testament, the Apostolic Epistles, the Acts, the Gospels, for your constant teachers. If grief befall thee, dive into them as into a chest of medicines; take thence comfort of thy trouble, be it loss, or death, or bereavement of relations; or rather dive not into them merely, but take them wholly to thee; keep them in thy mind.

This is the cause of all evils, the not knowing the Scriptures. We go into battle without arms, and how ought we to come off safe? Well contented should we be if we can be safe with them, let alone without them. Throw not the whole upon us! Sheep ye are, still not without reason, but rational; Paul committeth much to you also. They that are under instruction, are not for ever learning; for then they are not taught. If thou art for ever learning, thou wilt never learn. Do not so come as meaning to be always learning; (for so thou wilt never know;) but so as to finish learning, and to teach others.

[AD 407] John Chrysostom on Colossians 3:16
"Teaching," he saith, "and admonishing one another with psalms and hymns and spiritual songs." Mark also the considerateness of Paul. Seeing that reading is toilsome, and its irksomeness great, he led them not to histories, but to psalms, that thou mightest at once delight thy soul with singing, and gently beguile thy labors. "Hymns," he saith, "and spiritual songs." But now your children will utter songs and dances of Satan, like cooks, and caterers, and musicians; no one knoweth any psalm, but it seems a thing to be ashamed of even, and a mockery, and a joke. There is the treasury house of all these evils. For whatsoever soil the plant stands in, such is the fruit it bears; if in a sandy and salty soil, of like nature is its fruit; if in a sweet and rich one, it is again similar. So the matter of instruction is a sort of fountain. Teach him to sing those psalms which are so full of the love of wisdom; as at once concerning chastity, or rather, before all, of not companying with the wicked, immediately with the very beginning of the book; (for therefore also it was that the prophet began on this wise, "Blessed is the man that hath not walked in the counsel of the ungodly"; and again, "I have not sat in the council of vanity"; and again, "in his sight a wicked doer is contemned, but he honoreth those that fear the Lord," of companying with the good, (and these subjects thou wilt find there in abundance,) of restraining the belly, of restraining the hand, of refraining from excess, of not overreaching; that money is nothing, nor glory, and other things such like.

[AD 407] John Chrysostom on Colossians 3:16
When in these thou hast led him on from childhood, by little and little thou wilt lead him forward even to the higher things. The Psalms contain all things, but the Hymns again have nothing human. When he has been instructed out of the Psalms, he will then know hymns also, as a diviner thing. For the Powers above chant hymns, not psalms. For "a hymn," saith one, "is not comely in the mouth of a sinner"; and again, "Mine eyes shall be upon the faithful of the land, that they sit together with me"; and again, "he that worketh haughtiness hath not dwelt in the midst of my house"; and again, "He that walketh in a blameless way, he ministered unto me."

[AD 407] John Chrysostom on Colossians 3:16
What is the hymn of those above? The Faithful know. What say the cherubim above? What say the Angels? "Glory to God in the highest." Therefore after the psalmody come the hymns, as a thing of more perfection. "With psalms," he saith, "with hymns, with spiritual songs, with grace singing in your hearts to God." He means either this, that God because of grace hath given us these things; or, with the songs in grace; or, admonishing and teaching one another in grace; or, that they had these gifts in grace; or, it is an epexegesis and he means, from the grace of the Spirit. "Singing in your hearts to God." Not simply with the mouth, he means, but with heedfulness. For this is to "sing to God," but that to the air, for the voice is scattered without result. Not for display, he means. And even if thou be in the market-place, thou canst collect thyself, and sing unto God, no one hearing thee. For Moses also in this way prayed, and was heard, for He saith, "Why criest thou unto Me?" albeit he said nothing, but cried in thought-wherefore also God alone heard him-with a contrite heart. For it is not forbidden one even when walking to pray in his heart, and to dwell above.
