Why is Jesus' sacrifice "once for all"?
Why is Jesus' sacrifice described as "once for all" in Hebrews 7:27?

The Greek Term “Ephapax” – Meaning and Usage

The phrase “once for all” translates the adverb ἐφάπαξ (ephapax), which combines epi (“upon”) and hapax (“once”). It carries two emphases: finality (never to be repeated) and comprehensiveness (covering every need). The same word appears in Hebrews 9:12; 10:10; Romans 6:10; and 1 Peter 3:18—each time underscoring a single, decisive, and permanently effective act. No significant manuscript variation exists for the term in any extant Greek witness (𝔓¹², 𝔓⁴6, 𝔓⁸9, Codex Vaticanus, Codex Sinaiticus, etc.), reinforcing its original inclusion.


Contrast with the Aaronic Priesthood

Daily and yearly animal offerings (Exodus 29:38-42; Leviticus 16) were:

• Repetitive because the priests were sinful and the sacrifices were intrinsically limited (Hebrews 10:1-4).

• Temporally bound to the earthly tent (Hebrews 9:1-10).

Jesus, by contrast, is “holy, innocent, undefiled, separated from sinners, and exalted above the heavens” (Hebrews 7:26). He needs no sacrifice for Himself, so His single self-offering terminates the whole Levitical system.


Finality and Sufficiency of the Atonement

Christ’s death satisfies divine justice perfectly (Isaiah 53:5-6; 2 Corinthians 5:21). Because the sacrifice is of infinite worth—God the Son offering Himself—its merit extends beyond any finite number of sins or sinners. Hebrews 9:26 declares that “He has appeared once for all at the end of the ages to do away with sin by the sacrifice of Himself.” The resurrection (Hebrews 13:20) publicly confirms the Father’s acceptance, rendering additional offerings unnecessary.


Universality: For All Peoples and All Times

The preposition “for” (hyper) in Hebrews 7:27 carries the substitutionary sense—on behalf of. “All” (plural) embraces every believer of every epoch (John 1:29; Revelation 5:9-10). The same sacrifice underwrites redemption for Adam forward and will never need supplementation.


Compatibility with the Entire Canon

Psalm 110:4 foretells “You are a priest forever after the order of Melchizedek,” tying eternality to priestly work. Isaiah 53 anticipates a once-for-all, substitutionary Servant. Jesus’ words “It is finished” (John 19:30) use the perfect verb tetelestai, declaring a completed, continuing result—harmonizing perfectly with Hebrews.


Typology Fulfilled: Passover, Day of Atonement, and Levitical Offerings

• Passover lambs (Exodus 12) typify substitution and deliverance; Paul calls Christ “our Passover” (1 Corinthians 5:7).

• Yom Kippur’s annual goat (Leviticus 16) typifies expiation. Jesus enters the heavenly Holy of Holies “with His own blood” (Hebrews 9:12).

• Daily burnt offerings typify continual need; their cessation in A.D. 70 (attested by Josephus, War 6.2.1) historically illustrates the theological finality achieved at Calvary four decades earlier.


Christ’s Priestly Qualifications

1. Sinless nature (Hebrews 4:15).

2. Eternal life (“the power of an indestructible life,” Hebrews 7:16).

3. Divine appointment with an oath (Hebrews 7:21).

Because the offerer and the offering are identical, efficacy is absolute.


The Resurrection as Seal of the Once-for-All Sacrifice

Romans 6:10: “The death He died, He died to sin once for all; but the life He lives, He lives to God.” The empty tomb, attested by multiple early, independent sources (1 Corinthians 15:3-8; Synoptic Gospels; early creedal formula embedded in Acts 13:29-31), provides historical grounding. More than 97% of contemporary NT manuscripts include the resurrection narratives; earliest papyri (𝔓⁴6, 𝔓⁷5) affirm them. The resurrection therefore validates the sufficiency and permanence of the atonement.


Historical and Archaeological Corroboration

• Dead Sea Scroll 11Q13 (Melchizedek Scroll) shows Second-Temple Jews expecting an eschatological Melchizedek-like deliverer who proclaims “the year of favor.” Hebrews builds on this pre-Christian expectation.

• Inscribed ossuaries from the first century (e.g., Yehohanan’s heel bone with crucifixion nail) confirm the Roman method of execution described in the Gospels, corroborating the historical plausibility of Christ’s crucifixion.

• The Temple curtain’s massive weight (described in m. Shekalim 8.5) clarifies the miracle of its tearing at Jesus’ death (Matthew 27:51), symbolizing open access because the final sacrifice has occurred.


Philosophical and Behavioral Implications

A repeated-sacrifice system fosters perpetual guilt and performance-based acceptance. A once-for-all atonement produces assurance (Hebrews 10:22), moral transformation (Titus 2:14), and worshipful gratitude (Romans 12:1). The exclusivity of one sacrifice eliminates relativistic notions of multiple salvations, sharpening the ethical imperative to respond.


Practical Application for the Believer and the Skeptic

Believer: Rest from works-based striving; approach God with confidence (Hebrews 4:16).

Skeptic: Evaluate the historical evidence for a singular, decisive resurrection event; if it stands, the logic of Hebrews 7:27 follows inexorably—no other remedy for sin exists.


Summary

“Once for all” in Hebrews 7:27 affirms the finality, sufficiency, and universality of Christ’s self-offering. Grounded in impeccable textual evidence, foreshadowed throughout the Old Testament, vindicated by the resurrection, and corroborated by history and archaeology, this phrase encapsulates the heart of the gospel: one perfect Priest, one perfect sacrifice, one perfect salvation—for all who believe, for all time.
