“"So then death worketh in us, but life in you." Speaking no more of death in the strict sense, but of trials and of rest. 'For we indeed,' he says, 'are in perils and trials, but ye in rest; reaping the life which is the fruit of these perils. And we indeed endure the dangerous, but ye enjoy the good things; for ye undergo not so great trials.'”

“Having set down the patience of the apostles in evils, and the cause of that patience having been shown, here the apostle consequently makes these things clear; and first he makes clear what he said about the hope of glory; second, what he said about his patience, at the place "therefore we do not fail," etc. Concerning the first he does two things. First he makes clear the hope of glory which he has; second he shows whence this hope comes to him, at the place "but having the same," etc. Concerning the first he does three things. First he shows how he bears the mortification of Jesus in his body; second he makes clear how he bears the life of Jesus, at the place "that also the life," etc.; third he makes clear what comes of this for himself and for others, at the place "therefore death," etc. He says therefore first: I say that we bear the mortification in our bodies, not that we die, but because we who live, by bodily life or by virtues, are always handed over to death, or to the dangers of death. And this indeed, for the sake of Jesus. Ps. 43:22: "we are accounted as sheep," etc. But how we bear the life of Jesus in the body he explains, adding: "so," namely that the life of Jesus, immortal and impassible, may be made manifest in our flesh, now mortal, so that our mortal flesh may receive immortality in the resurrection. 1 Cor. 15:53: "but this mortal must put on," etc. But what comes of this, he adds, saying "therefore death works," that is, exercises its dominion in us, "but life," namely the present life, "works in you," because you are in prosperity, according to that word, 1 Cor. 4:10: "we are fools," etc. So that death works in us a great good, namely the attainment of spiritual life. Ps. 115:15: "precious in the sight of the Lord is the death of his saints," etc. But the earthly life which you love works in you a great evil, namely eternal death. Prov. 10:16: "the work of the just is unto life," etc. John 12:25: "he who loves his soul in this world," etc. Or otherwise: there were two things in Christ, bodily death and spiritual life. He says therefore "therefore death," etc., as if to say: in us not only does spiritual life work, insofar as we imitate spiritually, but death also works, that is, on account of the hope of resurrection, and on account of the love of Christ, the traces of the death of Christ appear in us, insofar as we are exposed to the sufferings of death, Ps. 43:22: "for thy sake we are put to death all the day long;" but in you only the life of Christ works, through which life faith is planted in you, and spiritual life. But whence this hope of certitude comes to the apostle, he adds, saying "but having," etc. And concerning this he does two things. First he sets down the cause of the certitude; second he concludes the certitude itself, at the place "knowing that he who," etc. But the cause of this certitude is the spirit, infusing faith into their hearts. Hence first he sets down this cause; second he makes it clear by an example, at the place "as it is written," etc. He says therefore: from this we hope and do not fail, because we are having the same spirit of faith which the ancients had, because, although the times have changed, yet the spirit and faith have not changed, except that they believed Christ was to come and to suffer, but we believe that he has come and has suffered. And this spirit is the Holy Spirit, who is the spirit of faith. 1 Cor. 12:11: "but all these things one and the same spirit works," etc. And in the same place: "to another faith in the same spirit." Having therefore this spirit, which the ancients had, we do the same things as they, and we believe. But what they did, Ps. 115:10 says: "I believed," namely God, and perfectly. And this all the ancients did. Heb. 11:39: "all these by the testimony of faith," etc. "For which cause," namely I believed, "I have spoken," that is, I have confessed the faith. Rom. 10:10: "with the heart we believe unto justice," etc. Which we also do, because on account of the fact that we believe, we speak and confess the faith and preach. Acts 4:20: "for we cannot but speak the things which we have seen and heard." The Holy Spirit therefore is the cause of this certitude. Finally therefore he concludes the intended conclusion, namely the certitude itself. And first concerning his own salvation; second concerning the salvation of others, at the place "and will set with you," etc. He says therefore "knowing," that is, having certain knowledge, "that he who raised up Jesus," that is, God the Father, or the whole Trinity, "will raise us also with Jesus," namely that we may take up the same glory with Jesus, because since we are his members, we ought to be with the head. John 12:26: "I will, Father, that where I am, there also my minister may be," etc. Rom. 8:11: "he who raised up the Lord Jesus from the dead, will raise," etc. And I am certain not only of our salvation, but also of yours, because "he will set us with you," that is, we shall be together; because just as we are members of Christ, so also you through us. 1 Thess. 4:16: "and so we shall always be with the Lord." Matt. 24:28: "wherever the body shall be," etc. And therefore he says "with you," so as to encourage them to good, insofar as he shows them not to be inferior, but equal. And well can I say this with certainty, because all things are for your benefit. For all things which we endure, all the graces which we receive from God, are for you, namely that you may be instructed by our example. And this for the reason that the grace abounding from us may abound in you through many unto the glory of God, that is, that many may give thanks to God for so great a benefit. Eph. 5:20: "giving thanks to God and the Father," etc.”

“So then death worketh in us, but life in you. Your spiritual life, your salvation is produced through faith and grace, but ours by the death of our body. The passion and death of the Apostles has been the life of the Church. “ The blood of the martyrs is the seed of the Church,” says Tertullian. Chrysostom gives a different explanation : “ You live in peace and suffer no such persecutions for the faith as I do ; and so you seem to live, and I seem to die daily.” DEATH IN LIFE SI We, having the same spirit of faith. As David was hemmed in with dangers, and yet was delivered by God alone from them all, and said : t€ I believed,” />., I believe that God will always be true to His promises and deliver me, so too do we believe and hope, and boldly profess that our help and strength, our deliverance and resurrection have been promised by God, and will most surely be wrought out Ps. cxvi., alluded to here by S. Paul, is a Eucharistic psalm, in which David gives God thanks for his safe deliverance. Hence it begins with, “ I believed.” In other words : I, David, in the midst of dangers and adversity, when hunted by Saul and his men, when my life was sought by Achish and the Philistines, when I was so placed that I seemed to be deprived of all human help, and to be in desperate straits, yet put my trust in God, who had promised me safety, and moreover the kingdom, by the mouth of Samuel. Wherefore, I said boldly that I believed, without doubting that God would deliver me from all these evils, and would bring me to His promised kingdom, as, in fact, He has delivered me, and has set me on the throne. “ Right dear in the sight of the Lord is the death of His Saints.” My death is of great account and great price in the sight of the Lord. God, therefore, carefully watches that my death, or that of His other Saints may not be allowed, except for good cause and great gain, and He wonderfully guards us and delivers us. This, I, David, found in the cave and at other times when I was shut in by the bands of Saul and of my other enemies, and therefore with praise and thanksgiving do I exclaim, What return shall I make unto the Lord for all the benefits that He hath done unto me ? I will receive the cup of salvation, of my many safe deliverances — that cup which is a witness and public profession of God’s goodness to me, and of my frequent escapes from danger — of God’s salvation will I take. Observe here that (i.) the Jews had three kinds of sacrifices, the whole burnt-offering, the sin-offering, and the peace-offering. This last was a sacrifice of salvation, offered for the peace and salvation of any individual or family, or of the whole people, whether 52 SECOND EPISTLE TO THE already obtained or to be obtained. (2.) In every sacrifice a libation was made to God, just as if the sacrifice were God's feast. The cup, therefore, of salvation is the cup of wine which was offered to God, poured out and drunk by the offerers. (3.) This cup was a figure of the Eucharistic chalice, which makes us not only mindful of the salvation wrought by Christ, but also partakers of it. Tropologically this “cup” is martyrdom and affliction, and the obstinate resistance that we make to sin, even unto death, says S. Basil, in his comments on Ps. cxvl For Paul eagerly longed for martyrdom, and hence he speaks not of the cross, but of the cup of salvation, as though he should say : I will readily drink whatever the Lord may have given to me, even though it be the martyr's death ; and therefore knowing, says S. Augustine, that martyrdom is not within my own power, but depends on the grace of God, I will call upon that grace, and will publicly preach and celebrate the name of the Lord. Similarly, Christ speaks of His Passion as a cup, and bids His Apostles and martyrs and all His members drink of it (S. Matt xx. 22, and xxvi. 42). As, then, every Christian offers to Christ, His Deliverer, the Eucharistic cup and sacrifice as a thanksgiving, so does Paul offer his sufferings, his afflictions, and death to Christ, as a most pleasing cup. So, too, have all the martyrs, by openly professing their faith and dying for it, offered to Christ the cup of their martyrdom. I believed. I believed, and I still believe. This is a continuous act of belief, and not merely one that is inchoate, especially so since David speaks of the person of Paul and of us all, and puts his own belief forward as one deserving our imitation”

“So then death worketh in us,.... This is the conclusion of the foregoing account, or the inference deduced from it; either the death, or dying of Christ, that is, the sufferings of his body, the church, for his sake, "is wrought in us"; fulfilled and perfected in us; see Col 1:24 or rather a corporeal death has seized upon us; the seeds of death are in us; our flesh, our bodies are mortal, dying off apace; death has already attacked us, is working on our constitutions gradually, and unpinning our tabernacles, which in a short time will be wholly took down and laid in the dust: but life in you. Some understand these words as spoken ironically, like those in Co1 4:8 but the apostle seems not to be speaking in such a strain, but in the most serious manner, and about things solemn and awful; and his meaning is, ours is the sorrow, the trouble, the affliction, and death itself, yours is the gain, the joy, the pleasure, and life; what we get by preaching the Gospel are reproach, persecution, and death; but this Gospel we preach at such expense is the savour of life unto life to you, and is the means of maintaining spiritual life in your souls, and of nourishing you up unto eternal life; and which is no small encouragement to us to go on in our work with boldness and cheerfulness: or these words regard the different state and condition of the apostle, and other ministers, and of the Corinthians; the one were in adversity, and the other in prosperity.”

“Death worketh in us, when we are under persecutions, and dangers of death, and life in you, who live in ease and plenty. (Witham) — The preaching of the gospel, which we undertake in such a disinterested manner, and which exposes us to so many dangers, is the cause of death to us, but of life to you. It draws down upon us a thousand dangers and disgraces; but procures you all kinds of advantages. You tranquilly enjoy the fruit of our labour, though we do not envy you this happiness, because we hope one day to enjoy the reward of our labours. (Calmet)”

“The "death" of Christ manifested in the continual "perishing of our outward man" (Co2 4:16), works peculiarly in us, and is the means of working spiritual "life" in you. The life whereof we witness in our bodily dying, extends beyond ourselves, and is brought by our very dying to you.”
