Brethren: Christ being come, a High Priest of the good things to come, by a greater and more perfect tabernacle, not made with hands, that is, not of this creation: neither by the blood of goats or of calves, but by His own blood, entered once into the Holies, having obtained eternal redemption. For if the blood of goats and of oxen and the ashes of an heifer, being sprinkled, sanctify such as are defiled, to the cleansing of the flesh: how much more shall the blood of Christ, who, by the Holy Ghost, offered Himself unspotted unto God, cleanse our conscience from dead works, to serve the living God? And therefore He is the Mediator of the new testament: that by means of His death, for the redemption of those transgressions which were under the former testament, they that are called may receive the promise of eternal inheritance, in Christ Jesus our Lord.
Verse 11. Christ coming is a high priest of the good things to come; of things which we hope for in heaven. — He has entered by a more perfect tabernacle; i.e. not passing, like the priests of the former law, into a tabernacle made by human art and hands, but by the tabernacle of his own body or flesh, says S. Chrys. framed by the Holy Ghost. Wi.
Verse 12. By the blood of goats, &c. This is another difference and pre-eminence of Christ above the priests of the law of Moses, that they could only offer the blood of beasts; but Christ entered into heaven by the effusion of his own precious blood in his sufferings, and on the cross, by this having found an eternal redemption for mankind, having satisfied for the sins of all men in the sight of God, which the former priests, with all their sacrifices, could not do. Wi. — Eternal redemption. By that one sacrifice of his blood, once offered on the cross, Christ our Lord paid and exhibited, once for all, the general price and ransom of all mankind; which no other priest could do. Ch. — The force of the apostle’s reasoning is to convince the Jews of the inefficacy of the legal sacrifices, and of the virtue of the Christian sacrifice.
Verse 13-14. For if the blood of goats, &c. Another main difference betwixt the sacrifices in the old, and that of Christ in the new law. Those imperfect carnal sacrifices could only make the priests and the people reputed clean, so that they were no longer to be treated as transgressors, and liable to punishments, prescribed and inflicted by the law: but the sacrifice of Christ has made our consciences interiorly clean, and sanctified them even in the sight of God. Having offered himself unspotted to God by the Holy Ghost, the divine Spirit of the Holy Ghost moving Christ as man to make this oblation of himself, though free from all sin, and incapable of sinning. And being this oblation, made by him, who was God as well as man, it was an oblation of infinite value, which repaired the injury done to God by sin, and redeemed mankind from the slavery of sin. Wi. — Here we have an abstract of the passion of Jesus Christ, or of the sacrifice of the cross. We see who is the priest, and who is the victim; we see the virtue and efficacy of this sacrifice, and why it was offered; also by what signs we may know whether we partake of it, viz. if dying to sin and to the world, we live to God, and serve him in spirit and truth. Calvin makes Jesus Christ a priest and mediator, according to his divinity; but in that case Christ would be inferior to his Father, not only as man, but according to his divinity: for the priest is inferior to the God to whom he offers sacrifice, which is an expression of supreme excellence. See Dr. Kellison’s survey of the Protestant religion.
Verse 15. And therefore he is the mediator of the new testament. The mediator, so as to be our Redeemer, which applies only to our Saviour, Christ. Moses is called a mediator betwixt God and his people. See Gal. iii. 19. and 1 Tim. ii. 5. &c. The saints in heaven, and men on earth, may be called mediators in an inferior and different sense: but Christ alone is the mediator who reconciled God to men, by satisfying for their sins, and by a redemption from the slavery of sin. This sense, in which Christ is the mediator of the New Testament is expressed in these following words: that by means of his death, for the redemption of those transgressions which were under the former testament, they who are called may receive the promise of eternal inheritance; that is, Christ by his death, redeemed all men. He names in particular the sins of those under the former testament, to shew them that the sacrifices of the Mosaical law could not of themselves obtain a remission of sins, so that all saved from Adam, or that shall be saved to the end of the world, have their sins forgiven, and obtain salvation by virtue of Christ’s sacrifice upon the cross. He paid the ransom of their sins, and is the Redeemer of all. Wi.
550—The Satisfaction of Christ, the Treasure of the Church
Indulgences From the Bull of jubilee, "Unigenitus Dei Filius," Jan. 25, 1343
The only begotten Son of God… “made unto us from God, wisdom, justice, sanctification and redemption” [1 Cor. 3], “neither by the blood of goats or of calves, but by His own blood entered once into the holies having obtained eternal redemption” [Heb. 9:12]. “For not with corruptible things as gold or silver, but with the precious blood of His very (Son) as of a lamb unspotted and unstained He has redeemed us” [cf.1 Pet. 1:18-19], who innocent, immolated on the altar of the Cross is known to have poured out not a little drop of blood, which however on account of union with the Word would have been sufficient for the redemption of the whole human race, but copiously as a kind of flowing stream, so that “from the soles of His feet even to the top of His Head no soundness was found in Him” [Is. 1:6]. Therefore, how great a treasure did the good Father acquire from this for the Church militant, so that the mercy of so great an effusion was not rendered useless, vain or superfluous, wishing to lay up treasures for His sons, so that thus the Church is an infinite treasure to men, so that they who use it, become the friends of God [Wis. 7:14].
