Hebrews 7:15

Another proof that the law, or economy, is changed, namely, forasmuch as Christ is appointed Priest, "not according to the law of a carnal (that is, a mere outward) commandment," but "according to the power of an indissoluble (so the Greek) life." The hundred tenth Psalm appoints Him "for ever" (Heb 7:17). The Levitical law required a definite carnal descent. In contrast stands "the power"; Christ's spiritual, inward, living power of overcoming death. Not agreeably to a statute is Christ appointed, but according to an inward living power. it--the change of the law or economy, the statement (Heb 7:12, Heb 7:18). far more--Greek, "more abundantly." for that--"seeing that," literally, "if"; so Rom 5:10. after the similitude of Melchisedec--answering to "after the order of Melchisedec" (Heb 5:10). The "order" cannot mean a series of priests, for Melchisedec neither received his priesthood from, nor transmitted it to, any other mere man; it must mean "answering to the office of Melchisedec." Christ's priesthood is similar to Melchisedec's in that it is "for ever" (Heb 7:16-17). another--rather as Greek, "a different."

The doctrine of the priestly office of Christ is so excellent in itself, and so essential a part of the Christian faith, that the apostle loves to dwell upon it. Nothing made the Jews so fond of the Levitical dispensation as the high esteem they had of their priesthood, and it was doubtless a sacred and most excellent institution; it was a very severe threatening denounced against the Jews (Hos 3:4), that the children of Israel should abide many days without a prince or priest, and without a sacrifice, and with an ephod, and without teraphim. Now the apostle assures them that by receiving the Lord Jesus they would have a much better high priest, a priesthood of a higher order, and consequently a better dispensation or covenant, a better law and testament; this he shows in this chapter, where, I. We have a more particular account of Melchisedec (Heb 7:1-3). II. The superiority of his priesthood to that of Aaron (Heb 7:4-10). III. An accommodation of all to Christ, to show the superior excellency of his person, office, and covenant (Heb 7:11 to the end).

7:15-17 This change of how God appoints priests (7:11-14) has been made very clear by the appointment of Jesus as a different priest. He, like Melchizedek, is a priest forever: Jesus’ resurrection from the dead shows that he has the power of a life that cannot be destroyed. Because his priesthood in the order of Melchizedek is superior to that of the Levites (7:1-10), he supersedes them as priest.
