20 And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven.
[AD 407] John Chrysostom on Colossians 1:19-20
Whatsoever things are of the Father, these he says are of the Son also, and that with more of intensity, because that He both became "dead" for, and united Himself to us. He said, "Firstfruits," as of fruits. He said not "Resurrection," but "Firstfruits," showing that He has sanctified us all, and offered us, as it were, a sacrifice. The term "fullness" some use of the Godhead, like as John said, "Of His fullness have all we received." That is, whatever was the Son, the whole Son dwelt there, not a sort of energy, but a Substance.

He has no cause to assign but the will of God: for this is the import of, "it was the good pleasure...in Him. And...through Him to reconcile all things unto Himself." Lest you should think that He undertook the office of a minister only, he says, "unto Himself." [2 Corinthians 5:18] And yet he elsewhere says, that He reconciled us to God, as in the Epistle he wrote to the Corinthians. And he well said, "Through Him to make an end of reconciling"; for they were already reconciled; but completely, he says, and in such sort, as no more to be at enmity with Him. How? For not only the reconciliation was set forth, but also the manner of the reconciliation. "Having made peace through the Blood of His Cross." The word "reconcile," shows the enmity; the words "having made peace," the war. "Through the Blood of His Cross, through Himself, whether things upon the earth, or things in the heavens." A great thing indeed it is to reconcile; but that this should be through Himself too, is a greater thing; and a greater still — how through Himself? Through His Blood. Through His Blood; and he said not simply His Blood, but what is yet greater, through the Cross. So that the marvels are five: He reconciled us; to God; through Himself; through Death; through the Cross. Admirable again! How he has mixed them up! For lest you should think that it is one thing merely, or that the Cross is anything of itself, he says "through Himself." How well he knows that this was a great thing. Because not by speaking words, but by giving Himself up for the reconciliation, He so wrought everything.

But what is "things in the heavens"? For with reason indeed is it said, "the things upon the earth," for those were filled with enmity, and manifoldly divided, and each one of us was utterly at variance with himself, and with the many; but how made He peace among "the things in the heavens"? Was war and battle there also? How then do we pray, saying, "Your will be done, as in heaven, so on earth"? [Matthew 6:10] What is it then? The earth was divided from heaven, the Angels had become enemies to men, through seeing the Lord insulted. "To sum up," he says, "all things in Christ, the things in the heavens, and the things upon the earth." [Ephesians 1:10] How? The things in heaven indeed in this way: He translated Man there, He brought up to them the enemy, the hated one. Not only made He the things on earth to be at peace, but He brought up to them him that was their enemy and foe. Here was peace profound. Angels again appeared on the earth thereafter, because that Man too had appeared in heaven. And it seems to me that Paul was caught up on this account [2 Corinthians 12:2], and to show that the Son also had been received up there. For in the earth indeed, the peace was twofold; with the things of heaven, and with themselves; but in heaven it was simple. For if the Angels rejoice over one sinner that repents, much more will they over so many.

All this God's power has wrought. Why then place ye confidence in Angels? says he. For so far are they from bringing you near, that they were ever your enemies, except God Himself had reconciled you with them. Why then run ye to them? Would you know the hatred which the Angels had against us, how great it was; and how averse to us they always were? They were sent to take vengeance in the cases of the Israelites, of David, of the Sodomites, of the Valley of weeping. [Exodus 23:20] Not so however now, but, on the contrary, they sang upon the earth [2 Samuel 24:16] with exceeding joy. And He led these down to men [Genesis 19:13], and led men up to them.

And observe, I pray you, the marvel in this: He brought these first down hither, and then he took up man to them; earth became heaven, because that heaven was about to receive the things of earth. Therefore when we give thanks, we say, "Glory to God in the highest, and on earth peace, good will to men." Behold, he says, even men appeared well-pleasing to Him thereafter. What is "good will"? [Ephesians 2:14; Deuteronomy 32:8, Septuagint] Reconciliation. No longer is the heaven a wall of partition. At first the Angels were according to the number of the nations; but now, not to the number of the nations, but that of the believers. Whence is this evident? Hear Christ saying, "See that you despise not one of these little ones, for their Angels do always behold the face of My Father which is in heaven." [Matthew 18:10] For each believer has an Angel; since even from the beginning, every one of those that were approved had his Angel, as Jacob says, "The Angel that feeds me, and delivers me from my youth." [Genesis 48:15-16], nearly If then we have Angels, let us be sober, as though we were in the presence of tutors; for there is a demon present also. Therefore we pray, asking for the Angel of peace, and everywhere we ask for peace (for there is nothing equal to this); peace, in the Churches, in the prayers, in the supplications, in the salutations; and once, and twice, and thrice, and many times, does he that is over the Church give it, "Peace be unto you." Wherefore? Because this is the Mother of all good things; this is the foundation of joy. Therefore Christ also commanded the Apostles on entering into the houses straightway to say this, as being a sort of symbol of the good things; for He says, "When ye come into the houses, say, Peace be unto you;" for where this is wanting, everything is useless. And to His disciples Christ said, "Peace I leave with you, My peace I give unto you." [John 14:27] This prepares the way for love. And he that is over the Church, says not, "Peace be unto you," simply, but "Peace be unto all." For what if with this man we have peace, but with another, war and fighting? What is the gain? For neither in the body, should some of its elements be at rest and others in a state of variance, is it possible that health should ever be upheld; but only when the whole of them are in good order, and harmony, and peace, and except the whole are at rest, and continue within their proper limits, all will be overturned. And, further, in our minds, except all our thoughts are at rest, peace will not exist. So great a good is peace, as that the makers and producers of it are called the sons of God [Matthew 5:9-45], with reason; because the Son of God for this cause came upon the earth, to set at peace the things in the earth, and those in the heavens. But if the peacemakers are the sons of God, the makers of disturbance are sons of the devil.

What do you say? Do you excite contentions and fightings? And does any ask who is so unhappy? Many there are who rejoice at evil, and who do rather rend in pieces the Body of Christ, than did the soldiers pierce it with the spear, or the Jews who struck it through with the nails. A less evil was that than this; those Members, so cut through, again united, but these when torn off, if they be not united here, will never be united, but remain apart from the Fullness. When you are minded to war against your brother, bethink you that you war against the members of Christ, and cease from your madness. For what if he be an outcast? What if he be vile? What if he be open to contempt? So says He, "It is not the will of My Father that one of these little ones should perish." [Matthew 18:14] And again, "Their Angels do always behold the face of My Father which is in heaven." [Matthew 18:10] God for his sake and yours even became a servant, and was slain; and do you consider him to be nothing? Surely in this respect also you fight against God, in that you deliver a judgment contrary to His. When he that is over the Church comes in, he straightway says, "Peace unto all"; when he preaches, "Peace unto all"; when he blesses, "Peace unto all"; when he bids to salute, "Peace unto all"; when the Sacrifice is finished, "Peace unto all": and again, in the middle, "Grace to you and peace." How then is it not monstrous, if, while hearing so many times that we are to have peace, we are in a state of feud with each other; and receiving peace, and giving it back, are at war with him that gives it to us? You say, "And to your spirit." And do you traduce him abroad? Woe is me! That the majestic usages of the Church have become forms of things merely, not a truth. Woe is me! That the watchwords of this army proceed no farther than to be only words. Whence also you are ignorant wherefore is said, "Peace unto all." But hear what follows, what Christ says; "And into whatsoever city or village you shall enter...as you enter into the house, salute it; and if the house be worthy, let your peace come upon it, but if it be not worthy, let your peace return to you." [Matthew 10:11-13] We are therefore ignorant; because we look upon this merely as a figure of words; and we assent not to them in our minds. For do I give the Peace? It is Christ who deigns to speak by us. Even if at all other times we are void of grace, yet are we not now, for your sakes. For if the Grace of God wrought in an ass and a diviner, for the sake of an economy, and the advantage of the Israelites [Numbers 22], it is quite clear that it will not refuse to operate even in us, but for your sakes will endure even this.

Let none say then that I am mean, and low, and worthy of no consideration, and in such a frame of mind attend to me. For such I am; but God's way always is, to be present even with such for the sake of the many. And, that you may know this, with Cain He vouchsafed to talk for Abel's sake [Genesis 4], with the devil for Job's [Job 1], with Pharaoh for Joseph's [Genesis 41], with Nebuchadnezzar for Daniel's [Daniel 2 and Daniel 4], with Belshazzar, for the same [Daniel 5]. And Magi moreover obtained a revelation [Matthew 2]; and Caiaphas prophesied, though a slayer of Christ, and an unworthy man, because of the worthiness of the priesthood. [John 11:49] And it is said to have been for this reason that Aaron was not smitten with leprosy. For why, tell me, when both had spoken against Moses did she alone suffer the punishment? [Numbers 12] Marvel not: for if in worldly dignities, even though ten thousand charges be laid against a man, yet is he not brought to trial before he has laid down his office, in order that it may not be dishonored along with him; much more in the case of spiritual office, be he whosoever he may, the grace of God works in him, for otherwise everything is lost: but when he has laid it down, either after he is departed or even here, then indeed, then he will suffer a sorer punishment.

Do not, I pray you, think that these things are spoken from us; it is the Grace of God which works in the unworthy, not for our sakes, but for yours. Hear ye then what Christ says. "If the house be worthy, let your peace come upon it." [Matthew 10:13-15] And how becomes it worthy? If "they receive you" [Luke 10:8], He says. "But if they receive you not, nor hear your words,...verily I say unto you, it shall be more tolerable for the land of Sodom and Gomorrha in the day of judgment, than for that city." What boots it then, that you receive us, and hear not the things we say? What gain is it that you wait upon us, and give no heed to the things which are spoken to you? This will be honor to us, this the admirable service, which is profitable both to you and to us, if you hear us. Hear also Paul saying, "I knew not, brethren, that he was High Priest." [Acts 23:5] Hear also Christ saying, "All whatsoever they bid you observe" [Matthew 23:3], that "observe and do." Thou despisest not me, but the Priesthood; when you see me stripped of this, then despise me; then no more will I endure to impose commands. But so long as we sit upon this throne, so long as we have the first place, we have both the dignity and the power, even though we are unworthy. If the throne of Moses was of such reverence, that for its sake they were to be heard, much more the throne of Christ. It, we have received by succession; from it we speak; since the time that Christ has vested in us the ministry of reconciliation.

Ambassadors, whatever be their sort, because of the dignity of an embassy, enjoy much honor. For observe; they go alone into the heart of the land of barbarians, through the midst of so many enemies; and because the law of embassy is of mighty power, all honor them; all look towards them with respect, all send them forth with safety. And we now have received a word of embassy, and we have come from God, for this is the dignity of the Episcopate. We have come to you on an embassy, requesting you to put an end to the war, and we say on what terms; not promising to give cities, nor so and so many measures of grain, nor slaves, nor gold; but the kingdom of heaven, eternal life, society with Christ, the other good things, which neither are we able to tell you, so long as we are in this flesh, and the present life. Ambassadors then we are, and we wish to enjoy honor, not for our own sakes, far be it, for we know its worthlessness, but for yours; that you may hear with earnestness the things we say; that you may be profited, that not with listlessness or indifference ye may attend to what is spoken. See ye not ambassadors, how all pay court to them? We are God's ambassadors to men; but, if this offend you, not we, but the Episcopate itself, not this man or that, but the Bishop. Let no one hear me, but the dignity. Let us then do everything according to the will of God, that we may live to the glory of God, and be counted worthy of the good things promised to those that love Him, through the grace and lovingkindness, etc. etc.

[AD 220] Tertullian on Colossians 1:20
For how is He before all, if He is not before all things? How, again, is He before all things, if He is not "the first-born of every creature"-if He is not the Word of the Creator? Now how will he be proved to have been before all things, who appeared after all things? Who can tell whether he had a prior existence, when he has found no proof that he had any existence at all? In what way also could it have "pleased (the Father) that in Him should all fulness dwell? " For, to begin with, what fulness is that which is not comprised of the constituents which Marcion has removed from it,-even those that were "created in Christ, whether in heaven or on earth," whether angels or men? which is not made of the things that are visible and invisible? which consists not of thrones and dominions and principalities and powers? If, on the other hand, our false apostles and Judaizing gospellers have introduced all these things out of their own stores, and Martian has applied them to constitute the fulness of his own god, (this hypothesis, absurd though it be, alone would justify him; ) for how, on any other supposition, could the rival and the destroyer of the Creator have been willing that His fulness should dwell in his Christ? To whom, again, does He "reconcile all things by Himself, making peace by the blood of His cross," but to Him whom those very things had altogether offended, against whom they had rebelled by transgression, (but) to whom they had at last returned? Conciliated they might have been to a strange god; but reconciled they could not possibly have been to any other than their own God.

[AD 373] Ephrem the Syrian on Colossians 1:20
Thus, as peace began to be [established], the angels proclaimed, “Glory in the highest and peace on earth.” When lower beings received [peace] from superior beings, “they cried, Glory on earth and peace in the heavens.” At that time when the divinity came down [and] was clothed in humanity, the angels cried, “Peace on earth.” And at the time when that humanity ascended in order to be absorbed into the divinity and sit on the right—“Peace in heaven”—the infants were crying forth before him, “Hosanna in the highest.” Hence, the apostle also learned that one should say, “He made peace by the blood of his cross [for] that which is in heaven and on earth.”

[AD 379] Basil of Caesarea on Colossians 1:20
For the true peace is above. Yet, as long as we were bound to the flesh, we were yoked to many things which troubled us. Seek, then, after peace, a release from the troubles of this world. Possess a calm mind, a tranquil and unconfused state of soul, which is neither agitated by the passions nor drawn aside by false doctrines that challenge by their persuasiveness to an assent, in order that you may obtain “the peace of God which surpasses all understanding and guards your heart.” He who seeks after peace, seeks Christ, because “he himself is our peace,” who has made two men into one new man, making peace, and “making peace through the blood of his cross, whether on earth or in the heavens.”
[AD 386] Cyril of Jerusalem on Colossians 1:20
The Savior endured all this, “making peace through the blood of the cross, for all things whether in the heavens or on the earth.” For we were enemies of God through sin, and God had decreed the death of the sinner. One of two things, therefore, was necessary, either that God, in his truth, should destroy all men, or that in his lovingkindness, he should remit the sentence. But see the wisdom of God; he preserved the truth of his sentence and the exercise of his lovingkindness. Christ took our sins “in his body upon the tree; that we, having died to sin,” by his death “might live to justice.” He who died for us was of no small worth; he was no material sheep; he was no mere man. He was more than an angel, he was God made man. The iniquity of sinners was not as great as the justice of him who died for them. The sins we committed were not as great as the justice he wrought, who laid down his life for us. He laid it down when he willed, and he took it up again when he willed.
[AD 407] John Chrysostom on Colossians 1:20
But what are “things in the heavens”? … The earth was divided from heaven, the angels had become enemies to men, through seeing the Lord insulted…. What Christ did on the cross was to translate up into heaven sinful humankind still in bondage to the evil one. Thus he, in effect, brought up to the angels the enemy, the hated one. Not only did he make the things on earth to be at peace, but he brought up to them the one who was their enemy and foe. Here was peace profound. Angels again appeared on the earth thereafter, because humankind from its side had appeared in heaven.
