How does Hebrews 7:12 illustrate the change in priesthood and law? A pivotal verse nestled in Hebrews 7 Hebrews 7:12: “For when the priesthood is changed, the law must be changed as well.” • One short sentence, yet it ties together two massive shifts: the replacement of the Levitical priesthood and the inauguration of a new covenantal order. • The writer assumes an unbreakable bond between priesthood and law; if God installs a different type of priest, the entire legal framework that supported the previous priesthood must also give way. Why a new priesthood was necessary • Hebrews 7:11 admits the Levitical system could not bring “perfection.” • Animal sacrifices covered sin temporarily (Hebrews 10:1–4) but never cleansed the conscience (Hebrews 9:9). • Psalm 110:4 predicted a forever-priest “in the order of Melchizedek,” signaling ahead of time that Aaron’s line was provisional. The Melchizedek connection: outside Levi • Melchizedek appears before the Law (Genesis 14:18-20), functioning as both priest and king—something the Mosaic system later kept separate. • Jesus, like Melchizedek, descends not from Levi but Judah (Hebrews 7:14), confirming that His priesthood operates on a different, superior plane. • Because tribe and genealogy defined Levitical eligibility, a priest from another tribe automatically requires a new governing principle. A change of law: from covenant of Sinai to covenant in Christ • “Changed” (Greek metathesis) means a transfer or relocation, not mere modification. • Hebrews 8:6-13 quotes Jeremiah 31:31-34 to explain that a new covenant replaces—rather than patches—the old. • Key contrasts: – External commands written on stone ➜ Internal law written on hearts (Jeremiah 31:33). – Repeated sacrifices ➜ One finished offering (Hebrews 10:12-14). – Priests who die ➜ A Priest who “lives forever” (Hebrews 7:24). • Galatians 3:24-26 and Romans 10:4 echo that the Law served as a tutor until Christ; now its ceremonial and priestly functions reach completion in Him. Scripture echoes that reinforce the shift • Exodus 28–29 vs. Hebrews 4:14-16—old garments, rituals, and intermediaries contrasted with our “great high priest who has passed through the heavens.” • Numbers 3:10 vs. Hebrews 7:16—Levitical priests appointed “according to legal requirement concerning bodily descent,” Jesus “by the power of an indestructible life.” • Colossians 2:14—God “canceled the record of debt that stood against us with its legal demands.” • Matthew 5:17—far from abolishing the Law, Jesus fulfills it, bringing its types and shadows to their intended reality. What it means for worship and daily life • Assurance: Because the new Priest never dies, our access to God is constant (Hebrews 7:25). • Freedom: We serve “in the new way of the Spirit, and not in the old way of the written code” (Romans 7:6). • Holiness: The inwardly written law empowers obedience from the heart, not merely external compliance. • Hope: The unchanging oath of God secures an unshakeable covenant (Hebrews 6:17-20), anchoring faith amid every trial. |
