“"Moreover he sprinkled with blood both the tabernacle and all the vessels of the ministry. And almost all things are by the law purged with blood, and without shedding of blood is no remission." Why the "almost"? why did he qualify it? Because those [ordinances] were not a perfect purification, nor a perfect remission, but half-complete and in a very small degree. But in this case He says, "This is the blood of the New Testament, which is shed for you, for the remission of sins." Where then is "the book"? He purified their minds. They themselves then were the books of the New Testament. But where are "the vessels of the ministry"? They are themselves. And where is "the tabernacle"? Again, they are; for "I will dwell in them," He says, "and walk in them." But they were not sprinkled with "scarlet wool," nor yet "with hyssop." Why was this? Because the cleansing was not bodily but spiritual, and the blood was spiritual. How? It flowed not from the body of irrational animals, but from the Body prepared by the Spirit. With this blood not Moses but Christ sprinkled us, through the word which was spoken; "This is the blood of the New Testament, for the remission of sins." This word, instead of hyssop, having been dipped in the blood, sprinkles all. And there indeed the body was cleansed outwardly, for the purifying was bodily; but here, since the purifying is spiritual, it entereth into the soul, and cleanseth it, not being simply sprinkled over, but gushing forth in our souls. The initiated understand what is said. And in their case indeed one sprinkled just the surface; but he who was sprinkled washed it off again; for surely he did not go about continually stained with blood. But in the case of the soul it is not so, but the blood is mixed with its very substance, making it vigorous and pure, and leading it to the very unapproachable beauty. Henceforward then he shows that His death is the cause not only of confirmation, but also of purification. For inasmuch as death was thought to be an odious thing, and especially that of the cross, he says that it purified, even a precious purification, and in regard to greater things. Therefore the sacrifices preceded, because of this blood. Therefore the lambs; everything was for this cause.”

“Vice is a sickness of the soul, and delusion is a loss of truth. Most men who are sick with the disease of vice and delusion proclaim health and are lauded by men. Unless the soul is cured from vice and is found in her natural state of health (with which she was created) so that she can be reborn by health of spirit, it is impossible for a man to desire the supernatural things of the Spirit. For so long as the soul is sick with passions, her senses have no perception of what is spiritual, and she does not even know how to desire it, saving only from the hearing of the ears and from writings.… Those who desire perfection must keep all the commandments, since the working of the commandments heals the powers of the soul. The practice of the commandments is not accomplished simply and by chance, for it is written that, "There is no remission without the shedding of blood." Our nature first received renewal through the incarnation of Christ, and it participated in His passion and death, and then, after the renewal of the shedding of blood, our nature was renewed and sanctified and became able to receive his new and perfect commandments. For if the new commandments had been given to men before the shedding of the Lord's blood, before our nature was renewed and sanctified, then it is perhaps possible that even the new commandments, like those of old, would have merely cut off vice from the soul but would have been unable completely to pluck out the very root of vice from her. But now it is not so; now there is a secret labour that accompanies the new, spiritual commandments. When the soul keeps these through the circumspection of the fear of God, they renew her, sanctify her and secretly heal all her members. For it is obvious which passion is quietly cured in the soul by each commandment. The operation of the commandments is perceived only by the healer and the healed, after the likeness of the woman who had an issue of blood.”

“Above, the Apostle expounded those things which were done in the old testament, and opened up their mystical exposition; here, from these things, he argues to his intended point, namely that the new testament is preferred over the old, because it can do what the old could not. And concerning this he does two things. For first he sets forth the conclusion he intends; second he proves something he had presupposed, at the place, For where a testament. Again the first is divided into two. For first he concludes from what has been said that Christ is the mediator; second he shows this — that the old testament could not do this — at the place, which were under the former. He says therefore: and therefore, namely because Christ entered into the holies, having found an eternal redemption, that is, leading unto eternal things, which the old could not do; hence it is necessary that this testament be other than that one, as the new is from the old. Ier. XXXI, 31: I will strike with the house of Israel and the house of Judah, et cetera. Apoc. XXI, v. 5: behold, I make all things new. Therefore Christ is the mediator of this new testament between God and man. I Tim. II, 5: the mediator of God and men, the man Christ Jesus. Now in every testament there is something which is promised, and something by which the testament is confirmed. But in the new testament heavenly and spiritual things are promised. Likewise this promise was confirmed by the death of Christ. And therefore Christ is the mediator of the new testament, that they who are called may receive the promise of eternal beatitude and of the eternal inheritance. And he says called, because this gift is not from works, but from the calling of God. Rom. VIII, 30: and whom he predestined, these he also called. I Thess. II, 12: we testified, that you should walk worthily of God, who has called you unto his kingdom and glory. Hence he says of the eternal inheritance, that is, of the eternal glory, which is our inheritance. I Pet. I, 3 s.: he has regenerated us unto a living hope, through the resurrection of Jesus Christ from the dead, unto an inheritance incorruptible, and undefiled, and unfading, reserved in the heavens. Ps. CXXVI, 4: behold the inheritance of the Lord. Likewise: the Lord is the portion of my inheritance. Now we have this inheritance through the death of Christ. Hence he says, a death coming between. I Pet. III, 9: unto this you were called, that you might possess a blessing by inheritance. The effect of this death is redemption from the transgression of sin. I Petr. I, 18 s.: you were redeemed from your vain manner of life, not with corruptible things, gold or silver, but with the precious blood of an unspotted lamb. But could this redemption from sins have been effected in the old testament? And he answers that it could not, because those transgressions were under the former testament; as if to say: because they could not be removed by the power of the sacraments of the former testament. Rom. III, 9: we have charged that Jews and Greeks are all under sin. But against this, because David and many other saints had remission of sins. I respond. It must be said that as to this effect, which is entrance into heaven, no, because through the death of Christ the door of life was opened. For no one entered before the death of Christ. Zach. IX, 11: but you, by the blood of your testament, have sent forth your prisoners out of the pit, wherein is no water. But as to the stain, in this way they did obtain it; yet not by the power of the sacraments of the old law, but in the faith of Christ. Thus therefore the new testament is more excellent than the old, because it is confirmed by the death of Christ, by which sins are remitted, and because it exhibits the promise. Then, when he says, For where a testament, he proves what he had presupposed, namely that the new testament is confirmed through the death of Christ. And first he proves this by the authority of human law; second by the authority of divine law, at the place, Whence neither was the first. He says therefore: it has been said that the new testament is confirmed through the intervening death of Christ, because in order for a testament to be valid, it is necessary that the death of the testator intervene; and therefore the new testament would not have force, unless the death of Christ had intervened. Hence it is said, Io. XI, 50: it is expedient for you, that one man die for the people. Now the death of the testator is necessary for two things. First, that the testament may have firmness, because since it is an expression of the last will, it can always be changed before death. Hence he says, that a testament is confirmed in the dead, that is, through death. And in this way the new testament is confirmed through the death of Christ. Matth. XXVI, 28: this is my blood of the new testament, namely its confirmer and dedicator. Second, the death of the testator is necessary in order that the testament be valid and have efficacy. Hence he says, otherwise it is not yet valid, because no one can claim anything, nor even can the heirs claim the inheritance by force of the testament, except after the death of the testator. Therefore Christ willed to interpose his death for us. Then, when he says, Whence neither was the first, he proves this same thing by the authority of divine law, namely by that which is found in the old testament. And concerning this he does two things. For first he shows the agreement between the two testaments; second he shows the difference, at the place, It is necessary therefore. Concerning the first he does two things, for first he proposes; second he makes it manifest, at the place, For when...had been read. He says therefore: thus it has been said, that in order for a testament to be valid, it is necessary that the death of the testator intervene. Nor should this seem surprising, because not even the first testament was dedicated, that is, confirmed, without blood. But that blood prefigured the blood of Christ. For all these things happened to them in figure, I Cor. X, 11. Then, when he says, For...having been read, he proves the point proposed, namely that that testament was not confirmed without blood. And he proves this with respect to three things, in which there was a use of blood. First with respect to the promulgation of the law; second with respect to the consecration of the tabernacle, at the place, the tabernacle also; third with respect to the purification of the vessels, at the place, and almost all things in blood. Concerning the first it must be known that the Apostle here touches on the history which is found in Ex. XXIV, 7, where it is said, that after Moses had read before the people the commandments of the Lord, and they answering, All the things which the Lord has spoken we will do, and we will be obedient, Moses took the blood which he had ordered to be kept from the twelve calves, and sprinkled the book of the law and the people, as it were in confirmation of the testament. And therefore he says, for when every commandment had been read, etc., because it was necessary that it be read. For that reading was the promulgation of the law. For it was necessary that the law be promulgated. Taking, et cetera. Here there is a twofold literal objection. One, because in Ex. XXIV no mention is made of a goat, but of twelve calves. The second, because there also no mention is made of water and scarlet and hyssop. The response to these two is twofold. One, namely, because the Apostle had been raised in the law; hence he knew that this was the practice in purifications according to the law, that the sprinkling was done with the blood of goats and calves and water mixed with hyssop and scarlet wool, as with a sprinkler; and therefore, although this is not treated of in Exodus, nevertheless the Apostle took this from the custom of the legal rite. Or it can be said that this was the first consecration. And therefore the other sanctifications to come were contained in it, as it were, virtually; among which the chief was that which was done on the day of expiation, concerning which Lev. XVI, and another concerning the red heifer, Num. XVI. In the first, however, there was the blood of a calf and a goat; but in the second, water and scarlet wool and hyssop. Therefore, because that first one contained these two, the Apostle referred the whole to that one. He says therefore, taking the blood, etc., he sprinkled the book and all the people, saying: this is the blood of the testament, which God has commanded to you, namely, its confirmer. Eccli. XXIV, 33: Moses commanded us a law in the precepts of justice. For this blood was a figure of the blood of Christ, by which the new testament was confirmed. And therefore Christ used these very words. Matth. XXVI, 28: this is the blood of the new testament, namely, confirmatory. Now it was prefigured by the blood of the goat on account of the likeness of sinful flesh, and by that of the calf on account of strength. It is mixed, however, with water, because Baptism has its efficacy from the blood of Christ; and it is sprinkled with hyssop, which cleanses the breast, by which faith is signified. Act. c. XV, 9: purifying their hearts by faith. And by the scarlet wool, which is of a red color, charity is signified. Cant. V, 10: my beloved is white and ruddy. For through faith and love of the passion of Christ the people is cleansed. The book of the law is sprinkled too, because the passion of Christ fulfilled the law. Io. XIX, 30: it is consummated. Matth. V, 17: I have not come to destroy the law, but to fulfill it. Then, when he says, the tabernacle also, he sets down the consecration of the tabernacle, because he likewise sprinkled with blood the tabernacle and all the vessels of the ministry. But against this, because the tabernacle had not yet been made, but in chapter XXV the consecration of the tabernacle is commanded. I respond. It must be said that although it is not the same blood by which the people and the tabernacle were sprinkled, nevertheless the tabernacle too was cleansed with blood. Hence it can be construed thus: he used blood, even when he sanctified the tabernacle. But against this, because in Num. and Lev. VIII it is said, that he anointed the tabernacle with oil. It is said, that he anointed the tabernacle with oil. I respond. It must be said that he is not speaking of that sanctification by which the tabernacle and its vessels were first consecrated, but of that which was done on the day of expiation. Or better, it must be said that he used blood also in the first, because it is said there that he anointed it with oil, and afterward that he sprinkled it. But oil is not a thing for sprinkling, hence it is understood that he first anointed it, and afterward sprinkled it with blood. And these two are necessary for sanctification, namely the power of the blood of Christ, and the oil of mercy, by which the tabernacle is sanctified, that is, the Church, and the vessels, that is, the ministers. Then, when he says, and almost all things according to the law are cleansed with blood, he goes on to treat of the other legal cleansings. Now there was a twofold cleansing: one from a bodily stain, such as leprosy; the other from a spiritual one, namely sin. The first could pertain to inanimate things, as is evident concerning the leprosy of houses. And the cleansing from this uncleanness was done with the blood of a slain animal, or with the water of expiation, which was made with the blood of the red heifer. And therefore he says almost all things, and not all things simply. Or almost all things, in such a way that the word "almost" qualifies the word "are cleansed," that is, they are almost cleansed, because they were not perfectly cleansed: this happens only through the sacrament of the new law. Or it can qualify the word "all." For not all things were cleansed with blood, because, as it is said, Num. XXXI, v. 23, whatever can endure fire is purged by fire; but those things which could not, are purged with the water of expiation. But for the cleansing from the stain of sin, the shedding of blood is necessary, because it was required for sacrifice. And therefore he says, that without the shedding of blood there is no remission of sins. By which it was prefigured that the remission of sin was to be brought about through the blood of Christ. Hence in the old law the remission of sins came about not by the power of the sacrament, but by the power of faith in Christ. Hence it is frequently said there, the priest shall pray for him, and it shall be forgiven.”

“And almost all things are by the law purged with blood,.... All "except a few things", as the Arabic version renders it; for some things were cleansed by water, and others purged by fire, Num 31:23. Some join the word almost with the word purged, as if the sense was, that all things were purged by blood, but not perfectly, only almost; but the former sense is best. And without shedding of blood is no remission; that is, of sin; there was no typical remission without it; and there can be no real remission but by, the blood of Christ; no instance can be given of pardon without it; if it could have been otherwise, the blood of Christ had not been shed; for so it would seem to be shed in vain, and his satisfaction to be unnecessary; nor is it agreeable to the justice of God to forgive sin without satisfaction; nor is it consistent with his veracity, and faithfulness to his word, Gen 2:17. It is a common saying with the Jews, and often to be met with in their writings, , "there is no atonement but by blood" (k); by the shedding of blood; not by the shedding of it, as it flows out of the body of the sacrifice, but as it is poured out on the altar; for the pouring of the blood at the four corners, and at the bottom of the altar, were the chief rites required in sacrifices; nor did they reckon expiation to be expiation, unless the altar was moistened by the blood of the sacrifice (l).

“And almost all things are - purged with blood - The apostle says almost, because in some cases certain vessels were purified by water, some by fire, Num 31:23, and some with the ashes of the red heifer, Num 19:2-10, but it was always understood that every thing was at first consecrated by the blood of the victim. And without shedding of blood is no remission - The apostle shows fully here what is one of his great objects in the whole of this epistle, viz. that there is no salvation but through the sacrificial death of Christ, and to prefigure this the law itself would not grant any remission of sin without the blood of a victim. This is a maxim even among the Jews themselves, אין כפרה אלא בדם ein capparah ella bedam, "There is no expiation but by blood." Yoma, fol. 5, 1; Menachoth, fol. 93, 2. Every sinner has forfeited his life by his transgressions, and the law of God requires his death; the blood of the victim, which is its life, is shed as a substitute for the life of the sinner. By these victims the sacrifice of Christ was typified. He gave his life for the life of the world; human life for human life, but a life infinitely dignified by its union with God.”

“St. Paul speaks here of legal purifications and remissions, which (ver. 10.) he calls carnal justices and ordinances, (ver. 13.) purifying the flesh. How then, it may be asked, were sins remitted under the law? I answer, by true repentance, joined with faith and hope in the promised Messias. As to the cleansings and expiations of the Mosaic law, they were generally effected by water and animal blood, and were typical of the real cleansing of the conscience by the water of baptism, and by the blood of Jesus Christ. The flowing, therefore, of the pure water and blood from the wound in Christ’s side, denoted that the real expiation was now complete, and the cleansing font set open; and on this account, they are appealed to by St. John, as two of the three terrestrial witnesses, whose testimony is so efficacious for the confirmation of our faith, that the crucified Jesus was the Christ foretold by the prophets. [John xix. 34; 1 John v. 6, 8.] And thus “the old law confirms the new, and the new fulfils the old.” (St. Paulinus)”

“almost--to be joined with "all things," namely almost all things under the old dispensation. The exceptions to all things being purified by blood are, Exo 19:10; Lev 15:5, &c.; Lev 16:26, Lev 16:28; Lev 22:6; Num 31:22-24. without--Greek, "apart from." shedding of blood--shed in the slaughter of the victim, and poured out at the altar subsequently. The pouring out of the blood on the altar is the main part of the sacrifice (Lev 17:11), and it could not have place apart from the previous shedding of the blood in the slaying. Paul has, perhaps, in mind here, Luk 22:20, "This cup is the new testament in my blood, which is shed for you." is--Greek, "takes place": comes to pass. remission--of sins: a favorite expression of Luke, Paul's companion. Properly used of remitting a debt (Mat 6:12; Mat 18:27, Mat 18:32); our sins are debts. On the truth here, compare Lev 5:11-13, an exception because of poverty, confirming the general rule.”
