📖 Biblical Definition
The high priesthood is the office of supreme mediation between God and His people. Under the Mosaic covenant, the high priest alone entered the Most Holy Place once a year with the blood of atonement, bearing the names of Israel on His breastplate and making intercession for the nation (Leviticus 16). Christ is the fulfillment of this office — "We have a great high priest who has passed through the heavens, Jesus, the Son of God" (Hebrews 4:14). Unlike the Aaronic priests who served temporarily and imperfectly, Christ holds His priesthood permanently, having offered Himself once for all as both priest and sacrifice (Hebrews 7:24-27). He now lives to intercede for His people at the right hand of God.

HIGH PRIEST, n. The chief priest. Among the Israelites, the high priest was at the head of all ecclesiastical affairs. He only had the privilege of entering the Holy of Holies. Note: Webster recognizes the unique mediatorial role of the high priest — a function now fulfilled exclusively and eternally by Christ.

• Hebrews 9:11-12 — "Christ appeared as a high priest... He entered once for all into the holy places... by means of His own blood."
• Leviticus 16:15-17 — "Then he shall kill the goat of the sin offering... and make atonement for the Holy Place."
⚠️ Modern Corruption
Christ's unique high priesthood is undermined by human mediatorial systems.
expand to see more
Any theological system that interposes a human mediator between the believer and God functionally denies Christ's high priesthood. When a priest claims to re-present Christ's sacrifice in the Mass, when a pastor positions himself as the necessary conduit of God's grace, when a denomination teaches that access to God requires institutional mediation — the sufficiency of Christ's once-for-all priestly work is compromised. The book of Hebrews is emphatic: the old priesthood is obsolete because Christ has established a better one. He needs no successor, no vicar, no replacement. He ever lives to make intercession, and every believer has direct access to the throne of grace through Him alone.
Usage
• "Christ's high priesthood is not temporary or transferable — He holds it permanently and needs no earthly successor."
• "The Aaronic high priest entered the Holy of Holies once a year with the blood of animals; Christ entered once for all with His own blood."
• "Because Jesus is our great High Priest, every believer has direct and immediate access to the throne of grace."
