“Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies, and the God of all comfort.”

Tertullian Patristic
c. A.D. 150–220
“If, owing to the fault of human error, the word God has become a common name (since in the world there are said and believed to be "gods many" ), yet "the blessed God," (who is "the Father) of our Lord Jesus Christ," will be understood to be no other God than the Creator, who both blessed all things (that He had made), as you find in Genesis, and is Himself "blessed by all things," as Daniel tells us.”

“Now, if the title of Father may be claimed for (Marcion's) sterile god, how much more for the Creator? To none other than Him is it suitable, who is also "the Father of mercies," and (in the prophets) has been described as "full of compassion, and gracious, and plenteous in mercy.”

“"Blessed be the God and Father of our Lord Jesus Christ." For in the thought of God, let the thought of Father be included, so that the glory which we ascribe to the Father and the Son with the Holy Spirit may be perfectly free from difference. For the Father has not one glory and the Son another, but their glory is one and the same, since the Son is the Father's sole-begotten. When the Father is glorified, the Son shares in enjoyment of his glory, because the Son draws his glory from the honoring of the Father. Again, whenever the Son is glorified, the Father of so excellent a Son is greatly honored.”

“God alone is holy and good, sanctifying others and making them good. He alone is blessed, because he gives blessing and does not receive it from someone else. Likewise, he is the Father of mercies by nature, because he is the source of all mercy and not because he has acquired this from anyone else.”

John Chrysostom Patristic
A.D. 347–407
“"Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort." Do you ask, how is this aptly to the purpose in hand? I reply, Very much so; for observe, they were greatly vexed and troubled that the Apostle had not come to them, and that, though he had promised, but had spent the whole time in Macedonia; preferring as it seemed others to themselves. Setting himself then to meet this feeling against him, he declares the cause of his absence; not however directly stating it, as thus; "I know, indeed, I promised to come, but since I was hindered by afflictions forgive me, nor judge me guilty of any sort of contempt or neglect towards you:" but after another manner he invests the subject at once with more dignity and trustworthiness, and gives it greatness by the nature of the consolation, so that thereafter they might not so much as ask the reason of his delay. Just as if one, having promised to come to one he longed for, at length arriving after dangers innumerable, should say, "Glory to Thee, O God, for letting me see the sight so longed for of his dear countenance! Blessed be Thou, O God, from what perils hast Thou delivered me!" for such a doxology is an answer to him who was preparing to find fault, and will not let him so much as complain of the delay; for one that is thanking God for deliverance from such great calamities he cannot for shame drag to the bar, and bid clear himself of loitering. Whence Paul thus begins, "Blessed be the God of mercies," implying by the very words that he had been both brought into and delivered from mighty perils. For as David also doth not address God every where in one way or with the same titles; but when he is upon battle and victory, "I will love Thee, he saith, O Lord my strength; the Lord is my buckler:" when again upon delivery from affliction and the darkness which overwhelmed him, "The Lord is my light and my salvation;" and as the immediate occasion suggests, he names Him now from His loving-kindness, now from His justice, now from His righteous judgment:-in like way Paul also here at the beginning describeth Him by His loving-kindness, calling Him "the God of mercies," that is, "Who hath showed me so great mercies as to bring me up from the very gates of death." And thus to have mercy is the peculiar and excellent attribute of God, and the most inherent in His nature; whence he calleth Him the "God of mercies." And observe, I pray you, herein also the lowly-mindedness of Paul. For though he were in peril because of the Gospel he preached; yet saith he not, he was saved for his merit, but for the mercies of God.”

“In the first epistle he promised to come to them, but since he did not come, he supposed that he had greatly grieved them with the thought that he had preferred others over them. So, wishing to justify himself and show that many temptations that had befallen him had delayed him, he offers a fine explanation in his defense. I give thanks, he says, to God who saved me from dangers; through this thanksgiving he hints that there were certain great obstacles holding him back, for deliverance from which he also gives thanks. Place a punctuation mark after the word "God," then begin: "and Father of the Lord." But if you understand this jointly—God and Father of the Lord—there will be nothing novel in it, for He is of one and the same Christ: by His humanity, God, and by His divinity, Father. That is, He showed such great mercies that He brought us out from the very gates of death and deemed us worthy of every consolation in afflictions. It was the custom of the saints to name God according to the benefits received from Him. Thus, on the occasion of victory in war, David says: "I will love You, O Lord, my strength" (Ps. 18:1), and again: "The Lord is the strength of my life" (Ps. 27:1); on the occasion of deliverance from the darkening and eclipsing of the mind and from grief: "The Lord is my light" (Ps. 27:1). So now Paul calls God the Father of mercies and the God of consolation as a result of what happened to him. Notice his humility: having received deliverance from trials for the sake of the Gospel, he does not say that the deliverance was according to merit, but according to the mercies of God.”

“If, I say, he shall have come in this, in this I shall know that he is not alone, but that his Father also has come with him. For what is so fatherly? On this account indeed he is called not only Father of the Word, but also Father of mercies, because it is innate in him always to have mercy and to spare.”

“Here begins the message, in which the Apostle does two things: first, he excuses himself for not visiting them as he had promised; secondly, he begins to follow out his intention (chap. 3). In regard to the first he does two things: first, he wins their good will; secondly, he presents his excuse (v. 15). In regard to the first he does two things: first, he wins their good will by citing some general facts; secondly, some special ones (v. 8). The Apostle wins their good will by showing that whatever he does, it is all for their benefit. In regard to this he does two things: first, he mentions the profit others have obtained from him; secondly, the reason (v. 5). In regard to the first he does three things: first, he gives thanks; secondly, the manner of the thanks (v. 4); thirdly, the cause (v. 4b). He gives thanks, therefore, to the entire Trinity, the source of every good; hence he says, Blessed be the God, i.e., the entire Trinity; and to the person of the Father when he says, and Father of our Lord Jesus Christ, through whom the Father has given us all things. It should be noted that we bless God and God blesses us, but in different ways. For when God speaks, he accomplishes: "He spoke and they were made" (Ps. 148:5). Hence, for God to bless is to produce something good, and to infuse something good, and so to be a cause: "I will indeed bless you and multiply your descendants" (Gen. 22:17). But our speech does not cause things, but acknowledges or expresses them; hence, our blessing is the same as recognizing good. Therefore, when we thank God, we bless him, i.e., acknowledge that he is good and the giver of all good: "Bless God and acknowledge him in the presence of all the living for the good things he has done for you" (Tob. 12:6); "Bless the Lord, all you works of the Lord; praise and exalt him above all for ever" (Dan. 3:57). It is fitting that he thank the Father, because he is merciful; hence he says, the Father of mercies: and because he is a comforter he says, and God of all comfort. He thanks God for the two things men especially need: first, to have evil removed from them, and this is done by mercy which takes away misery, for it is characteristic of a father to have compassion: "As a father pities his children, so the Lord pities those who fear him" (Ps. 103:13). Secondly, they need to be supported in the face of evils which occur, and that is to receive comfort. Because unless a man had something in which his heart could rest, he would not stand firm when evils come upon him. Therefore a person comforts another by affording him something refreshing, in which he can rest in evil times. And although a man might be comforted by something and find rest and be supported by it in the case of some evils, it is God alone who comforts us in all evils; hence he says, the God of all comfort. For if you sin, God comforts you, because he is merciful; if you are afflicted, he comforts you either by rooting out the affliction by his power or by judging justly; if you labor, he comforts you with a reward: "I am your shield; your reward shall be very great" (Gen. 15:1). Therefore, it says in Matthew (5:4): "Blessed are those who mourn, for they shall be comforted."”

“Paul always speaks in this way, indicating the personhood of the Father and the Son, even though they are of one substance. Now he is giving much relief to people who had been grieved by his rebuke, for when they hear that God is not just the Father of creation but the Father of mercies as well, they will have hope and be assured that they have been rebuked so that they may find the mercy of God, once they have mended their ways. Through repentance they were being born again and made anew, which was not just a pardon but a restoration of their previous state of existence. He puts "mercies" in the plural because of their many sins, his aim being to console those who have been grieved on account of their faults.”
