ἱερωσύνη
the priestly office
Definition
ἱερωσύνη refers to the priestly office or priesthood itself—the abstract concept of the role, function, and authority of a priest. In the New Testament, it is used exclusively in Hebrews 7 to discuss the Levitical priesthood established under the Mosaic Law (Hebrews 7:11, 7:12). The author contrasts this with the priesthood of Melchizedek, arguing that a change in priesthood necessitates a change in the law (Hebrews 7:12). The term emphasizes the official, institutional nature of the priesthood rather than the individual priests.
Biblical Usage
This word appears only in the Book of Hebrews, specifically in chapter 7, where it is used four times. It is employed in a theological argument about the insufficiency of the Levitical priesthood and its replacement by the priesthood of Jesus Christ according to the order of Melchizedek. For example, Hebrews 7:11 questions the perfection attainable through the Levitical priesthood (ἱερωσύνη), and Hebrews 7:12 states that a change of priesthood (ἱερωσύνη) means a change of law.
Etymology
Derived from the Greek adjective ἱερός (hieros, G2413), meaning 'holy' or 'sacred,' combined with the suffix -σύνη (-synē), which forms abstract nouns. Thus, ἱερωσύνη literally means 'holiness' or 'sacredness' in the sense of a sacred office. It is related to other priestly terms like ἱερεύς (hiereus, G2409) for 'priest' and ἱερατεία (hierateia, G2405) for 'priestly service.'
Semantic Range
This word is crucial for understanding the Book of Hebrews' argument about Christ's superior priesthood. It highlights the transition from the old covenant's temporary, imperfect Levitical system to the eternal, perfect priesthood of Jesus. Grasping the abstract concept of the 'priestly office' enriches reading by clarifying that Christ didn't just improve the old system but inaugurated an entirely new and permanent order of mediation between God and humanity (Hebrews 7:24).
In its original setting, ἱερωσύνη would have been understood in the context of Jewish temple worship and the hereditary Levitical priesthood. For Greek-speaking Jews and Gentiles, it conveyed the formal, institutional authority of priests who offered sacrifices and mediated divine things. The author of Hebrews uses this culturally familiar concept to argue for its obsolescence in light of Christ's work.
ἱερατεία (hierateia, G2405) — focuses more on the priestly service or ministry duties rather than the abstract office itself. ἱερεύς (hiereus, G2409) — refers to the individual person who is a priest.
