Hebrews 8:1-7

11 It would be very difficult for the Hebrews to acknowledge the failure of the Aaronic priesthood. Yet this is distinctly involved in the announcement of a priest after a different order. Had our Lord come of the family of Aaron, He would have been associated with an order which began in failure and which will never effect the reconciliation between God and His creatures which priesthood is intended to bring about: Hence His genealog1 proclaims Him Israel's King, but He ignores all genealogies in His priestly place. Instead, He has the much higher honor of being qualified for office by the divine oath, including an assurance that, unlike the Aaronic priesthood, there will be no regrets for the failure and insufficiency of His ministry.

23 If the Melchizedek priesthood should last forever (instead of for the eon) then it too, would come under the condemnation of never bringing anything to perfection or finality. Then there would be a temple and priesthood on the new earth; indeed, it would continue beyond the consummation, and form an insurmountable barrier between God and some of His creatures. Priesthood is a sign of estrangement; it vanishes when God is at peace with His people. Hence, though the Lord's life is indissoluble (Heb_7:16) and the priesthood inviolate (Heb_7:24), unbroken by death, it is always limited to one eon, beyond which there call be no priesthood, because there is no estrangement.

26 The glories of this Chief Priest refer to His relation to God, to men, to the law. He is knit to God by loving devotion. He is innocent of any tinge of malice toward men, and He is undefiled by a spot of moral defilement. He is separate from Sinners because of His exaltation to His office.

27 The fact that the sacrificial system under the law demanded sacrifices for the sins of the priests as well as for the people, shows that it was a weak and imperfect and temporary expedient. Add to this the fact that these sacrifices continued to be offered daily, and never brought any permanent relief, and we see clearly that it was never intended to do more than suggest the true Sacrifice, which the Son offered once, which needs no repetition. It is evident, therefore, that He could not have associated Himself with the Aaronic order without degrading His great sacrifice. They served among the shadows of the heavenly tabernacle. He entered the true.

1 The tabernacle and temple furniture did not include a seat. The high priest's work was never completed, hence, he never sat down in the holy places. In striking contrast, the Chief Priest of the new order has finished His work, and sits at the right hand of the Majesty in the heavens. The "sum" is that the sanctuary is heaven itself: the Chief Priest is the Son of God. His priestly work began after His ascension (v. Heb_8:4). Aaronic priesthood was instituted at Sinai (Ex.24) after Israel had been redeemed; for the purpose of maintaining the people in the blessedness of redemption.

5 The tabernacle and its service were patterned after a heavenly original; It was not an exact copy, however, but an adumbration or shadow, merely giving the main outlines. The heavenly offerings seem to be mainly oblations or gifts, and probably had no sacrificial victims other than the great sacrifice of Christ. The earthly copy was given to teach the great lessons of God's righteousness and holiness, and man's unfitness and distance from Him, as well as the way of approach which is acceptable to Him until the true Sacrifice pours out His soul and makes an end of sins.

6 The heavenly tabernacle is not associated with the covenant and promises which came from Sinai along with the earthly model. Everything connected with the new Mediator is better. This is especially true of the new covenant which He will make when the kingdom commences.
