“These things I cannot ask from any but the God from whom I know I shall obtain them, both because He alone bestows them and because I have claims upon Him for their gift, as being a servant of His, rendering homage to Him alone, persecuted for His doctrine, offering to Him, at His own requirement, that costly and noble sacrifice of prayer despatched from the chaste body, an unstained soul, a sanctified spirit, not the few grains of incense a farthing buys -tears of an Arabian tree,-not a few drops of wine,-not the blood of some worthless ox to which death is a relief, and, in addition to other offensive things, a polluted conscience, so that one wonders, when your victims are examined by these vile priests, why the examination is not rather of the sacrificers than the sacrifices.”

“For since a person's nature is twofold, compounded of soul and body, the purification is also twofold, incorporeal for the incorporeal part, bodily for the body. For as the water purifies the body, so the Spirit seals the soul, that having our hearts sprinkled and our bodies washed with clean water, we may draw near to God. Therefore, when about to enter the water, do not regard it as mere water, but look for its saving power by the efficacy of the Holy Spirit, for without both you cannot be made perfect. It is not I who say this, but the Lord Jesus, who has the power in this matter, says, "Unless one is born of water and the Spirit, he cannot enter the kingdom of God." Neither does he who is baptized but has not been deemed worthy of the Spirit possess perfect grace; nor will one who acts virtuously, but does not receive the seal by water, enter into the kingdom of heaven. This may appear a bold saying, but it is not mine, for it was Jesus who pronounced it.”

“"Let us draw near" (he says) "with a true heart." To what should we "draw near"? To the holy things, the faith, the spiritual service. "With a true heart, in full assurance of faith," since nothing is seen; neither the priest henceforth, nor the sacrifice, nor the altar. And yet neither was that priest visible, but stood within, and they all without, the whole people. But here not only has this taken place, that the priest has entered into the holy of holies, but that we also enter in. Therefore he says, "in full assurance of faith." For it is possible for the doubter to believe in one way, as there are even now many who say, that of some there is a resurrection and of others not. But this is not faith. "In full assurance of faith" (he says); for we ought to believe as concerning things that we see, nay, even much more; for "here" it is possible to be deceived in the things that are seen, but there not: "here" we trust to the senses, but there to the Spirit. "Having our hearts sprinkled from an evil conscience." He shows that not faith only, but a virtuous life also is required, and the consciousness to ourselves of nothing evil. Since the holy of holies does not receive "with full assurance" those who are not thus disposed. For they are holy, and the holy of holies; but here no profane person enters. They were sprinkled as to the body, we as to the conscience, so that we may even now be sprinkled over with virtue itself. "And having our body washed with pure water." Here he speaks of the Washing, which no longer cleanses the bodies, but the soul. What is "let us draw near with a true heart"? That is, without hypocrisy; for "woe be to a fearful heart, and faint hands": let there be (he means) no falsehood among us; let us not say one thing and think another; for this is falsehood; neither let us be fainthearted, for this is not [a mark] of a "true heart." Faintheartedness comes from not believing. But how shall this be? If we fully assure ourselves through faith. "Having our hearts sprinkled": why did he not say "having been purified"? Because he wished to point out the difference of the sprinklings: the one he says is of God, the other our own. For the washing and sprinkling the conscience is of God; but "the drawing near with" truth and "in full assurance of faith" is our own. What is "and having our bodies washed with pure water"? With water which makes pure; or which has no blood.”

“After the Apostle has shown the manifold preeminence of the priesthood of Christ in comparison with the priesthood of the Law, here, according to his custom, he draws a conclusion, admonishing that this priesthood must be faithfully adhered to. For this he has always done above: that after a commendation he places an admonition, because he had undertaken to commend the grace of Christ for this purpose, that he might draw them to obey Christ and to withdraw from the ceremonial observances of the Law. Concerning this, then, he does two things: first he sets down the admonition; second he assigns the reason, at the place, for willingly. Now it must be known, concerning the first, that he had said two things about the priesthood of Christ: namely, the power of its rite, because through his own blood; and also its dignity, because a priest forever. And therefore in his admonition he takes up these two again. Hence, in admonishing that God-Christ must be faithfully obeyed, first he sets down those two things; second he sets down his admonition, at the place, let us draw near with a good heart. Likewise the first is divided into two, because first he resumes the rite of his priesthood; second, the dignity, at the place, and a great priest. He says therefore, Therefore, brethren — namely, through mutual charity — having confidence in the entrance, etc. Eph. 3:12: In whom we have boldness and access with confidence, etc. Ex. 15:17: Thou shalt bring them in, and plant them in the mountain of thy inheritance, thy most firm habitation, etc. Ps. 121:1: I rejoiced at the things that were said to me: we shall go into the house of the Lord. And this in the blood of Christ, because this is the blood of the new testament, that is, of the new promise, namely of heavenly things. But how we may have confidence to enter he shows, because Christ through his own blood initiated — that is, began — a new way for us. Mic. 2:13: He is gone up that shall open the way before them. Jn. 14:3: If I shall go, and prepare a place for you, etc. Is. 35:8: It shall be called the holy way, and the polluted shall not pass over it. This, then, is the way of going into heaven. And it is new because before Christ no one found it, since no one ascends into heaven except him who descended from heaven, Jn. 3:13. And therefore whoever wishes to ascend must adhere to him as a member to its head. Apoc. 2:7: To him that overcometh, I will give to eat of the tree of life, which is in the paradise of my God. And ch. 3:12: And I will write upon him a new name, and the name of the new city, Jerusalem — namely, because they are led in anew. Living — that is, ever-enduring — in which the power of the deity appeared, because he always lives. But what this way is he shows by adding, through the veil, that is, his flesh. For just as the priest entered into the holy of holies through the veil, so if we wish to enter into the holy places of glory, we must enter through the flesh of Christ, which was the veil of the deity. Is. 45:15: Verily thou art a hidden God. For faith concerning the deity does not suffice, if faith concerning the incarnation is not present. Jn. 14:1: You believe in God, believe also in me. Or through the veil, that is, through his flesh given to us under the veil of the appearance of bread in the sacrament. For it is not set before us under its own species, on account of horror, and on account of the merit of faith. Consequently he commends the dignity of the priest, when he says, and a great priest — namely, one who initiated the way for us — as if he were to say: having confidence to enter through the priest, namely Jesus. Ps. 109:5: Thou art a priest forever. He is called great because his priesthood is not only over one people, as Aaron's, but over the whole house of God, namely the Church militant and triumphant. 1 Tim. 3:15: That thou mayest know how thou oughtest to behave thyself in the house of God, which is the Church. And he says over, because Moses was faithful in all the house, as a servant, Num. 12:7; but Christ is over the whole house, as a son, who is lord of all. Matt., last chapter: All power is given to me in heaven and on earth. Of this also above, ch. 3. Then, when he says, let us draw near, he sets down his admonition: namely, that since he is such and so great, one must faithfully adhere to him. This is done in three ways: namely through faith, hope, and charity. 1 Cor. 13:13: And now there remain faith, hope, charity. First, therefore, he admonishes concerning the things that belong to faith; second, concerning the things that belong to hope, at the place, let us hold fast hope; third, concerning the things that belong to charity, at the place, and let us consider. But as to the first, two things are necessary: namely, faith itself, because without faith it is impossible to please God, and the sacrament of faith. As to the first he says, let us draw near — to him — with a true, not feigned, heart. 4 Kings 20:3 and Is. 38:3: Remember how I have walked before thee in truth and with a perfect heart. Now this is done when the work agrees with the heart. Let us draw near also in the fullness of faith. Below, 11:6: He that cometh to God must believe, etc. Nor does just any faith suffice, but a full faith is required, which comes about in two ways: namely, as to the matter of faith, that all things which are proposed for belief be believed; and that the faith be formed, which is through charity. Rom. 13:10: For the fulness of the law is love. As to the sacrament of faith it is said, your hearts sprinkled, which alludes to what is said in Num. 19, where the rite of the red heifer is set down, by whose water the one to be cleansed was sprinkled on the third day, but on the seventh day his body and his garments were washed with other water. By the sprinkling of the water of the red heifer the passion of Christ was figured, because on the third day — that is, in the faith of the Trinity — we are cleansed from sins in Baptism. And as to this he says, hearts sprinkled, not bodies. Below, 12:24: You are come to the sprinkling of blood. Hearts, therefore, sprinkled not from contact with the dead, as by the water of the red heifer, but from an evil conscience. Concerning the washing, however, which took place on the seventh day, he says, and our bodies washed with clean water. For in Baptism not only does the power of the passion operate, but the gifts of the Holy Spirit are also poured in. Hence on the seventh day, that is, in the fullness of the gifts of the Holy Spirit, the whole man is washed within and without from every sin, both actual and original, which is, as it were, corporeal, because the soul contracts it through its union with defiled flesh. Now the Holy Spirit is called water because he cleanses. Acts 15:9: Purifying their hearts by faith. Ez. 36:25: I will pour upon you clean water, and you shall be cleansed from all your filthiness, and I will cleanse you from all your idols. Zach. 13:1: There shall be a fountain open to the house of David, and to the inhabitants of Jerusalem, for the washing of the sinner and of the unclean woman. Tit. 3:5: By the laver of regeneration and renovation of the Holy Spirit. And as a sign of this, the Holy Spirit descended upon Christ when baptized, in bodily form. Then, when he says, let us hold fast our hope, he sets down what pertains to hope. And concerning this he does two things. For first he exhorts to the certitude of hope; second he adds the reason, at the place, for he is faithful who. Now it must be known that through the faith of Christ there is given to us the hope of eternal salvation, and of entrance into heaven. 1 Pet. 1:3: He hath regenerated us unto a lively hope. Hence he says, let us hold fast, and he does not say hope, but the confession of our hope, because it does not suffice to have hope in the heart, but it is also necessary to confess it with the mouth. Rom. 10:10: With the heart we believe unto justice, but with the mouth confession is made unto salvation. Likewise it is necessary to confess it not only in word, but also in deeds, against certain persons, of whom Tit. 1:16 says: They profess that they know God, but in their works they deny him. Now this confession is made through works, by which one tends toward the things hoped for. Apoc. 3:11: Hold fast that which thou hast, that no man take thy crown. Without wavering — that is, that we may not turn aside from this confession, neither through prosperity nor through adversity. Ps. 124:5: But such as turn aside into bonds, the Lord shall lead out with the workers of iniquity. Is. 30:21: This is the way, walk ye in it, and turn not aside neither to the right hand nor to the left. And the reason for this is that he who has promised is faithful, and therefore cannot lie. Ps. 144:13: The Lord is faithful in all his words. Deut. 32:4: A faithful God and without any iniquity. Consequently, when he says, and let us consider, etc., he sets down what pertains to charity, and concerning this he does three things. For first he does what has been said; second he removes what is contrary to charity, at the place, not forsaking; third he assigns the reason from the fitness of the time, at the place, and so much the more, etc. Concerning the first it must be known that although charity principally adheres to God, nevertheless it is made manifest through charity toward one's neighbor. 1 Jn. 4:20: For he that loveth not his brother whom he seeth, how can he love God whom he seeth not? Therefore it pertains to charity that one's neighbor be loved. Therefore he says, let us consider one another — namely, that we may do carefully the things that are our neighbor's. Ecclus. 17:12: And God gave commandment to each one concerning his neighbor. But because some consider the things that are their neighbor's out of the zeal of envy, and others indeed out of the zeal of hatred — against whom it is said, Prov. 24:15: Seek not wickedness in the house of the just — therefore he says, unto a provocation of charity, that is, that we may provoke them to charity. Rom. 11:13ff.: As long as I am the apostle of the Gentiles, I will honor my ministry, if by any means I may provoke to emulation my flesh, and may save some of them. Now this provocation proceeds from love, which extends to outward work. 1 Jn. 3:18: Let us not love in word, nor in tongue, but in deed and in truth. For as Gregory says, the love of God is not idle; for it works great things if it exists, but if it refuses to work, it is not love. The proof of love, therefore, is the showing forth of works. Therefore he adds, and of good works. Col. 1:10: Being fruitful in every good work. Then he removes what is contrary to charity, when he says, not forsaking, etc. For since charity is love, and the proper effect of love is to unite — because, as Dionysius says, love is a unitive force — Jn. 17:22ff.: That they may be one, as we also are one; and the world may know that thou hast loved them, as thou hast also loved me — therefore to withdraw from one another is directly opposed to charity. And therefore he says, not forsaking our assembly — namely, of the Church — which some forsake in three ways. Namely, by apostatizing from the faith on account of persecutions. And these are signified by those of whom it is said, Jn. 6:67, that they went back, and walked no more with him. Matt. 13:21: When tribulation and persecution ariseth because of the word, they are presently scandalized. Lk. 8:13: For a while they believe, and in time of temptation they fall away. Second, evil prelates who abandon the sheep in danger. Jn. 10:13: The hireling flieth, because he is a hireling. Others, indeed, out of pride, because although they could be useful for governing, they separate themselves from others with a mark of pride, Jude 5:19: These are they who separate themselves, sensual men, having not the Spirit — as it were under the guise of greater perfection. And perhaps such men existed in that time. Therefore there follows, as is the custom of some. Against whom it is said, 1 Cor. 11:16: If any man seem to be contentious, we have no such custom in the Church of God. But what they ought to do he adds, but comforting, as if he were to say: if you see that your companion is faring badly, do not forsake him, but comfort him — not like those who forsake the assembly, of whom he says, as is the custom of some, etc. Consequently, when he says, and so much the more, he assigns the cause of this. For someone might say: why ought we to progress in faith? Because the more a natural motion approaches its term, the more it is intensified. The contrary holds of a violent motion. But grace inclines after the manner of nature; therefore those who are in grace, the more they approach the end, the more they ought to grow. And therefore he said, not forsaking, as some do, but comforting. And this, so much the more as you see the day approaching, that is, the end. Rom. 13:12: The night is past, and the day is at hand. Prov. 4:18: The path of the just, as a shining light, goeth forwards and increaseth even to perfect day.”

“And let us consider one another,.... Saints should consider one another as men, that they are but men, of like passions and infirmities; they should consider their different tempers, and make allowance for them, and their outward state and condition in the world: they should consider one another as saints, partakers of the same grace; as that they are all loved with the same love, all conceived and brought forth in the womb of God's eternal electing grace, interested in the same covenant, redeemed by the same blood, and have the same graces and privileges, and an equal right to glory; having one and the same Spirit, the same grace of faith, the same righteousness, the same fountain to wash in, the same fulness to partake of, the same throne of grace to go to, and the same inheritance to enjoy: they should consider one another as church members, the grace and gifts of the another, their different age and standing in the church, their relation to each other as brethren; they should consider them under suffering or sorrowful circumstances, under afflictions, temptations, desertions, declensions, and as attended with infirmities and sins: and the end of such consideration should be, to provoke unto love; to brotherly love, to stir it up, and stir up to it, which is apt to wax cold, that so it may be rekindled, and give a most vehement flame; for this is Christ's new commandment, the bond of perfection, the evidence of regeneration, that which makes the saints' communion comfortable and delightful, and without which a profession of religion is in vain. And to good works; not for justification before God, and in order to procure salvation; but that God may be glorified, the Gospel adorned, the mouths of gainsayers stopped, faith evidenced to the world, and gratitude to God for his benefits shown, and for the profit and advantage of fellow creatures, and fellow Christians.”

“Let us draw near - Let us come with the blood of our sacrifice to the throne of God: the expression is sacrificial. With a true heart - Deeply convinced of our need of help, and truly in earnest to obtain it. In full assurance of faith - Being fully persuaded that God will accept us for the sake of his Son, and that the sacrificial death of Christ gives us full authority to expect every blessing we need. Having our hearts sprinkled - Not our bodies, as was the case among the Hebrews, when they had contracted any pollution, for they were to be sprinkled with the water of separation, see Num 19:2-10; but our hearts, sprinkled by the cleansing efficacy of the blood of Christ, without which we cannot draw nigh to God. From an evil conscience - Having that deep sense of guilt which our conscience felt taken all away, and the peace and love of God shed abroad ill our hearts by the Holy Ghost given unto us. Our bodies washed with pure water - The high priest, before he entered into the inner tabernacle, or put on his holy garments, was to wash his flesh in water, Lev 16:4, and the Levites were to be cleansed the same way, Num 8:7. The apostle probably alludes to this in what he says here, though it appears that he refers principally to baptisms, the washing by which was an emblem of the purification of the soul by the grace and Spirit of Christ; but it is most likely that it is to the Jewish baptisms, and not the Christian, that the apostle alludes.”

“(Heb 4:16; Heb 7:19.) with a true heart--without hypocrisy; "in truth, and with a perfect heart"; a heart thoroughly imbued with "the truth" (Heb 10:26). full assurance-- (Heb 6:11); with no doubt as to our acceptance when coming to God by the blood of Christ. As "faith" occurs here, so "hope," and "love," Heb 10:23-24. sprinkled from--that is, sprinkled so as to be cleansed from. evil conscience--a consciousness of guilt unatoned for, and uncleansed away (Heb 10:2; Heb 9:9). Both the hearts and the bodies are cleansed. The legal purifications were with blood of animal victims and with water, and could only cleanse the flesh (Heb 9:13, Heb 9:21). Christ's blood purifies the heart and conscience. The Aaronic priest, in entering the holy place, washed with water (Heb 9:19) in the brazen laver. Believers, as priests to God, are once for all washed in BODY (as distinguished from "hearts") at baptism. As we have an immaterial, and a material nature, the cleansing of both is expressed by "hearts" and "body," the inner and the outer man; so the whole man, material and immaterial. The baptism of the body, however, is not the mere putting away of material filth, nor an act operating by intrinsic efficacy, but the sacramental seal, applied to the outer man, of a spiritual washing (Pe1 3:21). "Body" (not merely "flesh," the carnal part, as Co2 7:1) includes the whole material man, which needs cleansing, as being redeemed, as well as the soul. The body, once polluted with sin, is washed, so as to be fitted like Christ's holy body, and by His body, to be spiritually a pure and living offering. On the "pure water," the symbol of consecration and sanctification, compare Joh 19:34; Co1 6:11; Jo1 5:6; Eze 36:25. The perfects "having . . . hearts sprinkled . . . body (the Greek is singular) washed," imply a continuing state produced by a once-for-all accomplished act, namely, our justification by faith through Christ's blood, and consecration to God, sealed sacramentally by the baptism of our body.”
