{3} And no man taketh this honour unto himself, but he that is called of God, as was Aaron.

(3) The third comparison which is complete: The others are called by God and so was Christ, but in another order than Aaron. For Christ is called the Son, begotten by God and a Priest for ever after the order of Melchizedek.

People's New Testament

5:4 And no man taketh this honour unto himself. He must be called to it by God.

As was Aaron. Aaron was so appointed. See Ex 28:1 Le 8:2.

Wesley's Notes

5:4 The apostle begins here to treat of the priesthood of Christ. The sum of what he observes concerning it is, Whatever is excellent in the Levitical priesthood is in Christ, and in a more eminent manner; and whatever is wanting in those priests is in him. And no one taketh this honour - The priesthood. To himself, but he that is called of God, as was Aaron - And his posterity, who were all of them called at one and the same time. But it is observable, Aaron did not preach at all; preaching being no part of the priestly office.

Jamieson-Fausset-Brown Bible Commentary

4. no man-of any other family but Aaron's, according to the Mosaic law, can take to himself the office of high priest. This verse is quoted by some to prove the need of an apostolic succession of ordination in the Christian ministry; but the reference here is to the priesthood, not the Christian ministry. The analogy in our Christian dispensation would warn ministers, seeing that God has separated them from the congregation of His people to bring them near Himself, and to do the service of His house, and to minister (as He separated the Levites, Korah with his company), that content with this, they should beware of assuming the sacrificial priesthood also, which belongs to Christ alone. The sin of Korah was, not content with the ministry as a Levite, he took the sacerdotal priesthood also. No Christian minister, as such, is ever called Hiereus, that is, sacrificing priest. All Christians, without distinction, whether ministers or people, have a metaphorical, not a literal, priesthood. The sacrifices which they offer are spiritual, not literal, their bodies and the fruit of their lips, praises continually (Heb 13:15). Christ alone had a proper and true sacrifice to offer. The law sacrifices were typical, not metaphorical, as the Christian's, nor proper and true, as Christ's. In Roman times the Mosaic restriction of the priesthood to Aaron's family was violated.

Matthew Henry's Concise Commentary

5:1-10 The High Priest must be a man, a partaker of our nature. This shows that man had sinned. For God would not suffer sinful man to come to him alone. But every one is welcome to God, that comes to him by this High Priest; and as we value acceptance with God, and pardon, we must apply by faith to this our great High Priest Christ Jesus, who can intercede for those that are out of the way of truth, duty, and happiness; one who has tenderness to lead them back from the by-paths of error, sin, and misery. Those only can expect assistance from God, and acceptance with him, and his presence and blessing on them and their services, that are called of God. This is applied to Christ. In the days of his flesh, Christ made himself subject to death: he hungered: he was a tempted, suffering, dying Jesus. Christ set an example, not only to pray, but to be fervent in prayer. How many dry prayers, how few wetted with tears, do we offer up to God! He was strengthened to support the immense weight of suffering laid upon him. There is no real deliverance from death but to be carried through it. He was raised and exalted, and to him was given the power of saving all sinners to the uttermost, who come unto God through him. Christ has left us an example that we should learn humble obedience to the will of God, by all our afflictions. We need affliction, to teach us submission. His obedience in our nature encourages our attempts to obey, and for us to expect support and comfort under all the temptations and sufferings to which we are exposed. Being made perfect for this great work, he is become the Author of eternal salvation to all that obey him. But are we of that number?
