Carnal commandment, etc. It was called carnal, because it refers to things corporal, that is, to external rites. We know how Aaron and his sons were initiated into their office. What was fulfilled in Christ by the hidden and celestial power of the Spirit, was shadowed forth under the Law by ointment, various vestments, the sprinkling of blood, and other earthly ceremonies. Now this kind of institution was suitable to the nature of the priesthood; it hence follows, that the priesthood itself was liable to change. At the same time, as we shall hereafter see, the priesthood was not so carnal, but that it was still spiritual; but the Apostle here refers only to the difference between Christ and Aaron. However spiritual then might have been the meaning of these shadows, they were yet but shadows in themselves; and as they were made up of the elements of this world, they may justly be called earthly. After the power of an endless life, or, of an indissoluble life. As Christ is a perpetual priest, it was necessary, that he should be different from Aaron as to the manner of his appointment; and so it was, for it was not Moses, a mortal man, who consecrated him, but the Holy Spirit, and that not with oil, nor with the blood of goats, nor with the outward pomp of vestments, but with celestial power, which the Apostle here sets in opposition to weak elements. We hence see how the eternity of his priesthood was exhibited in Christ.

Who is made - That is, the other priest is made, to wit, the Messiah. He was made a priest by a special law.
Not after the law of a carnal commandment - Not according to the Law of a commandment pertaining to the flesh. The word "carnal" means "fleshly;" and the idea is, that the Law under which the priests of the old dispensation were made was external, rather than spiritual; it related more to outward observances than to the keeping of the heart. That this was the nature of the Mosaic ritual in the main, it was impossible to doubt, and the apostle proceeds to argue from this undeniable truth.
But after the power of an endless life - By an authority of endless duration. That is, it was not concerned mainly with outward observances, and did not pass over from one to another by death, but was unchanging in its character, and spiritual in its nature. It was enduring and perpetual as a priesthood, and was thus far exalted above the service performed by the priests under the former dispensation.

Who is made - Appointed to this high office by God himself, not succeeding one that was disabled or dead, according to that law or ordinance directed to weak and perishing men, who could not continue by reason of death.
This is probably all that the apostle intends by the words carnal commandment, εντολης σαρκικης· for carnal does not always mean sinful or corrupt, but feeble, frail, or what may be said of or concerning man in his present dying condition.
But after the power of an endless life - Not dying, or ceasing through weakness to be a priest; but properly immortal himself, and having the power to confer life and immortality on others. He ever lives, as Priest, to make intercession for men; and they who believe on him shall never perish, but have everlasting life.

(8) Who is made, not after the (g) law of a carnal commandment, but after the power of an endless life.
(8) He proves the diversity and excellency of the institution of Melchizedek's priesthood, by this that the priesthood of the law rested on an outward and bodily anointing: but the sacrifice of Melchizedek is set out to be everlasting and more spiritual.
(g) Not after the ordination, which commands frail ad temporary things, as was done in Aaron's consecration, and all of that whole priesthood.

Who was made,.... Not as man, much less as God; but as a priest, constituted and appointed one:
not after the law of a carnal commandment: either the ceremonial law in general, which was a carnal one, if we consider the persons to whom it belonged, the Israelites according to the flesh; it was incumbent upon, and might be performed by such who were only carnal; and it was performed by and for men that were in the flesh, or mortal; and if we consider the matter of it, the subject on which various of its rites were exercised was the flesh or body, and which were performed by manual operation; and the sacrifices of it were the flesh of beasts; and these were for the sins of the flesh, and for the removing the ceremonial uncleanness of it; and the virtue of them reached only to the purifying of the flesh; and the whole of it is distinct from the moral law, which is spiritual, and reaches to the spirit or soul of man; whereas this only was concerned about temporal and external things: or else the law of the priesthood is particularly intended; or that commandment which respected the priesthood of Aaron; which law regarded the carnal descent of his sons; enjoined a carnal inauguration of them, and provided for their succession and continuance in a carnal way; after which, Christ the great high priest did not become one:
but after the power of an endless life; this may be understood either of the Gospel, according to which Christ is a priest; and which is called "life", in opposition to the law which is the ministration of death; and because it is the means of quickening dead sinners, and of reviving drooping saints; and points out Christ the way of life, and has brought life and immortality to light: and may be said to be "endless", in distinction from the law, which is temporary; and because it is itself permanent and everlasting; contains in it the promise of eternal life, and is the means of bringing souls unto it: and there is a "power" goes along with it; which distinguishes it from the weak and beggarly elements of the ceremonial law, which is abolished, because of the weakness of it; for it is attended with the power of the Spirit of God, and is the power of God unto salvation: or else this intends the endless life which Christ has, in and of himself; and which qualifies him for a priest; and stands opposed to the mortality of the priests, and to that law which could not secure them from it: the priests died, and the law by which they were priests could not prevent their death; Christ is the living God, the Prince of life, he had power to lay down his life as man, and power to take it up again; and his life, as man, is an endless one, which qualifies him for that part of his priestly office, his intercession and advocacy: or it may design that power, which his Father has given him as Mediator, of an endless life, both for himself and for all his people; and regards his ever living as a priest, and the perpetuity of and the continual virtue and efficacy of it.

carnal . . . endless--mutually contrasted. As "form" and "power" are opposed, 2-Timothy 3:5; so here "the law" and "power," compare Romans 8:3, "The law was weak through the flesh"; and Hebrews 7:18, "weakness." "The law" is here not the law in general, but the statute as to the priesthood. "Carnal," as being only outward and temporary, is contrasted with "endless," or, as Greek, "indissoluble." Commandments is contrasted with "life." The law can give a commandment, but it cannot give life (Hebrews 7:19). But our High Priest's inherent "power," now in heaven, has in Him "life for ever"; Hebrews 9:14, "through the eternal Spirit"; Hebrews 7:25, "able . . . ever liveth" (John 5:26). It is in the power of His resurrection life, not of His earthly life, that Christ officiates as a Priest.

Who is made - A priest. Not after the law of a carnal commandment - Not according to the Mosaic law, which consisted chiefly of commandments that were carnal, compared to the spirituality of the gospel. But after the power of an endless life - Which he has in himself, as the eternal Son of God.
