{5} For if he were on earth, he should not be a priest, seeing that there are priests that offer gifts according to the law:

(5) He gives a reason why he said that our High Priest is in the heavenly sanctuary, and not in the earthly: because, says he, if he were now on the earth, he could not minister in the earthly sanctuary, seeing there are still Levitical priests who are appointed for him, that is to say, to be patterns of that perfect example. To what purpose should the patterns serve, when the true and original example is present?

People's New Testament

8:4 For if he were on earth, he should not be a priest. The law required all the priests who served in the temple to be of the tribe of Levi, but he was not of the tribe of Levi (see notes on Heb 7:13,14), or of the priests appointed to serve at the altar, hence could not serve at an earthly altar, or in any earthly sanctuary. The law was in force as long as he was on earth and that excluded him.

Wesley's Notes

8:4 But if he were on earth - If his priesthood terminated here. He could not be a priest - At all, consistently with the Jewish institutions. There being other priests - To whom alone this office is allotted.

King James Translators' Notes

there...: or, they are priests

Jamieson-Fausset-Brown Bible Commentary

4. Implying that Christ's priestly office is exercised in heaven, not in earth; in the power of His resurrection life, not of His earthly life.

For-The oldest manuscripts read, "accordingly then."

if, &c.-"if He were on earth, He would not even (so the Greek) be a priest" (compare Heb 7:13, 14); therefore, certainly, He could not exercise the high priestly function in the earthly Holy of Holies.

seeing that, &c.-"since there are" already, and exist now (the temple service not yet being set aside, as it was on the destruction of Jerusalem), "those (the oldest manuscripts omit 'priests') who offer the (appointed) gifts according to (the) law." Therefore, His sacerdotal "ministry" must be "in the heavens," not on earth (Heb 8:1). "If His priesthood terminated on the earth, He would not even be a priest at all" [Bengel]. I conceive that the denial here of Christ's priesthood on earth does not extend to the sacrifice on the cross which He offered as a priest on earth; but applies only to the crowning work of His priesthood, the bringing of the blood into the Holy of Holies, which He could not have done in the earthly Holy of Holies, as not being an Aaronic priest. The place (the heavenly Holy of Holies) was as essential to the atonement being made as the oblation (the blood). The body was burnt without the gate; but the sanctification was effected by the presentation of the blood within the sanctuary by the high priest. If on earth, He would not be a priest in the sense of the law of Moses ("according to the law" is emphatic).

Matthew Henry's Concise Commentary

8:1-6 The substance, or summary, of what had been declared was, that Christians had such a High Priest as they needed. He took upon himself human nature, appeared on earth, and there gave himself as a sacrifice to God for the sins of his people. We must not dare to approach God, or to present any thing to him, but in and through Christ, depending upon his merits and mediation; for we are accepted only in the Beloved. In all obedience and worship, we should keep close to God's word, which is the only and perfect standard. Christ is the substance and end of the law of righteousness. But the covenant here referred to, was that made with Israel as a nation, securing temporal benefits to them. The promises of all spiritual blessings, and of eternal life, revealed in the gospel, and made sure through Christ, are of infinitely greater value. Let us bless God that we have a High Priest that suits our helpless condition.

Matthew Henry's Whole Bible Commentary

Chapter 8

In this chapter the apostle pursues his former subject, the priesthood of Christ. And, I. He sums up what he had already said (v. 1, 2). II. He sets before them the necessary parts of the priestly office (v. 3-5). And, III. Largely illustrates the excellency of the priesthood of Christ, by considering the excellency of that new dispensation or covenant for which Christ is the Mediator (v. 6 to the end).

Verses 1-5

Here is, I. A summary recital of what had been said before concerning the excellency of Christ's priesthood, showing what we have in Christ, where he now resides, and what sanctuary he is the minister of, v. 1, 2. Observe, 1. What we have in Christ; we have a high priest, and such a high priest as no other people ever had, no age of the world, or of the church, ever produced; all others were but types and shadows of this high priest. He is adequately fitted and absolutely sufficient to all the intents and purposes of a high priest, both with respect to the honour of God and the happiness of men and himself; the great honour of all those who have an interest in him. 2. Where he now resides: He sits on the right hand of the throne of the Majesty on high, that is, of the glorious God of heaven. There the Mediator is placed, and he is possessed of all authority and power both in heaven and upon earth. This is the reward of his humiliation. This authority he exercises for the glory of his Father, for his own honour, and for the happiness of all who belong to him; and he will by his almighty power bring every one of them in their own order to the right hand of God in heaven, as members of his mystical body, that where he is they may be also. 3. What is that sanctuary of which he is a minister: Of the true tabernacle, which the Lord hath pitched, and not man, v. 2. The tabernacle which was pitched by man, according to the appointment of God. There was an outer part, in which was the altar where they were to offer their sacrifices, which typified Christ dying; and there was an interior part within the veil, which typified Christ interceding for the people in heaven. Now this tabernacle Christ never entered into; but, having finished the work of satisfaction in the true tabernacle of his own body, he is now a minister of the sanctuary, the holy of holies, the true tabernacle in heaven, there taking care of his people's affairs, interceding with God for them, that their sins may be pardoned and their persons and services accepted, through the merit of his sacrifice. He is not only in heaven enjoying great dominion and dignity, but, as the high priest of his church, executing this office for them all in general, and every member of the church in particular.

II. The apostle sets before the Hebrews the necessary parts of Christ's priesthood, or what it was that belonged to that office, in conformity to what every high priest is ordained to, v. 3, 4. 1. Every high priest is ordained to offer gifts and sacrifices. Whatever was brought by the people to be presented to God, whether expiatory sacrifices, or peace-offerings, or thank-offerings, must be offered by the priest, who was to expiate their guilt by the blood of the sacrifice, and perfume their gifts and services by his holy incense, to render their persons and performances typically acceptable; so then it necessarily belongs to the priesthood of Christ that he should have somewhat to offer; and he, as the antitype, had himself to offer, his human nature upon the altar of his divine nature, as the great atoning sacrifice that finished transgression, and made an end of sin once for all; and he has the incense of his own righteousness and merits too to offer with all that his people offer up to God by him, to render them acceptable. We must not dare to approach to God, or to present any thing to him, but in and through Christ, depending upon his merits and mediation; for if we are accepted, it is in the Beloved. 2. Christ must now execute his priesthood in heaven, in the holy of holies, the true tabernacle which the Lord hath fixed. Thus the type must be fully answered; having finished the work of sacrificing here, he must go into heaven, to present his righteousness and to make intercession there. For, (1.) If Christ were on earth, he would not be a priest (v. 4), that is, not according to the Levitical law, as not being of the line of that priesthood; and so long as that priesthood continued there must be a strict regard paid to the divine institution in everything. (2.) All the services of the priest, under the law, as well as every thing in that tabernacle which was framed according to the pattern in the mount, were only exemplars and shadows of heavenly things, v. 5. Christ is the substance and end of the law for righteousness. Something therefore there must be in Christ's priesthood that answers to the high priest's entering within the veil to make intercession, without which he could not have been a perfect priest; and what is this but the ascension of Christ into heaven, and his appearance there in the sight of God for his people, to present their prayers, and plead their cause? So that, if he had still continued on earth, he could not have been a perfect priest; and an imperfect one he could not be.
