Leviticus 7:31's link to atonement?
How does Leviticus 7:31 relate to the concept of atonement in Christianity?

Text and Immediate Context

“‘The priest shall burn the fat on the altar, but the breast belongs to Aaron and his sons.’ ” (Leviticus 7:31)

Leviticus 7:28-34 closes the regulations for the peace (or fellowship) offering. Verse 31 singles out two actions: (1) all the fat is burned for Yahweh, and (2) the breast is assigned to the priestly family. Although the peace offering is distinct from the sin (ḥaṭṭāʾt) and guilt (ʾāšām) offerings, its ritual flows out of, and presupposes, the prior removal of guilt (Leviticus 4–6). Thus, every detail—including the burning of the fat—functions against the backdrop of atonement already achieved and now enjoyed.


The Peace Offering as a Fruit of Atonement

1. Sequence in Leviticus. The order in Leviticus—sin/guilt offerings first, peace offering afterward (Leviticus 6:24–7:21)—highlights this principle: atonement (Hebrew kippēr, “to cover”) must precede communion.

2. Name and Purpose. “Peace” (šělāmîm) denotes wholeness and restored relationship. The worshiper, priest, and God share one sacrificial meal, dramatizing reconciliation already secured.

3. Descriptive Link. Leviticus 7:15 calls the peace offering “a sacrifice of thanksgiving.” New-covenant writers pick up that language when they speak of “the sacrifice of praise” (Hebrews 13:15), a direct echo of the peace offering that follows Christ’s once-for-all atonement.


Fat Burned to Yahweh: Symbol of Complete Surrender

1. The Best for God. In the ancient Near East, fat was prized as the richest part of the animal. Burning it entirely to Yahweh proclaimed His absolute priority (cf. Leviticus 3:16, “all the fat is the LORD’s”).

2. Substitutionary Message. As the choicest portion rose in smoke, the worshiper witnessed a life laid down in his place (Leviticus 17:11). Atonement’s logic—life for life—was re-enacted each time.

3. Anticipation of Christ. Ephesians 5:2 describes Messiah’s self-offering as “a fragrant offering and sacrifice to God,” language lifted straight from the Levitical aroma formula (e.g., Leviticus 1:9). The fat-on-the-altar motif prefigures Christ’s total consecration.


Priestly Portion: Mediation and Shared Table

1. Breast to the Priest. The breast (symbolizing affection and strength) is waved before Yahweh (Leviticus 7:30) and then eaten by Aaron’s sons, highlighting their mediatory role.

2. Table Fellowship. Priest and worshiper dine together on holy meat (Leviticus 7:15-18), pointing to the greater communion meal of the new covenant (1 Corinthians 10:16-18).

3. Christ Our High Priest. Hebrews 2:17 says Jesus became “a merciful and faithful high priest in service to God, to make atonement for the sins of the people.” He both offers and is the sacrifice, then invites believers to His table (Revelation 19:9).


Canonical Trajectory Toward the Cross

1. Isaiah 53. The Servant offers Himself as an ʾāšām (guilt offering, Isaiah 53:10), merging concepts of sin removal and peace.

2. Zechariah 3:9. “I will remove the iniquity of this land in a single day” anticipates the once-for-all act that the repeated Levitical burnings foreshadow.

3. Hebrews 9:11-14. The writer explicitly contrasts the continual animal sacrifices with Christ’s single, definitive offering that “obtained eternal redemption.”


Archaeological and Extra-Biblical Corroboration

• The Tel Arad temple complex (10th-9th century B.C.) yielded altars with thick layers of charred animal fat, matching Levitical practice.

• Elephantine papyri (5th century B.C.) record Jewish soldiers directing portions of sacrificial animals to priests, echoing Leviticus 7:31.

• Temple Mount sifting project fragments include bowls inscribed with priestly names from the first-century Herodian temple, underscoring the living continuity of the priestly portions described in Moses’ day.


Theological Synthesis: Atonement in Christian Doctrine

1. Substitution. The fat burned entirely illustrates the life substituted; Christ fulfills this typology (2 Corinthians 5:21).

2. Propitiation and Reconciliation. Peace-offering fellowship results only because wrath has been satisfied. Romans 5:10 merges these concepts: “while we were enemies we were reconciled to God through the death of His Son.”

3. Priesthood of Believers. Because the breast was given to priests, and believers are now “a royal priesthood” (1 Peter 2:9), Christians symbolically share in what Leviticus 7:31 anticipated: ongoing fellowship grounded in completed atonement.


Practical and Devotional Implications

• Gratitude. Like the worshiper who brought a peace offering, believers respond to Christ’s atonement with thanksgiving, not self-payment.

• Consecration. All life “fat” belongs to God; Romans 12:1 calls believers to present their bodies as living sacrifices.

• Communion. Participation in the Lord’s Supper re-enacts the peace-offering meal: remembrance, fellowship, proclamation of the death that achieved atonement (1 Corinthians 11:26).


Conclusion

Leviticus 7:31, at first glance a procedural note about fat and priestly portions, actually functions as a theological microcosm. The total dedication of the fat to Yahweh and the shared portion given to the mediators embody the logic of substitutionary atonement and reconciled fellowship. In the broad sweep from Sinai to Calvary, this verse becomes a quiet yet vivid pointer to the once-for-all sacrifice of the Son of God, through whom peace with God is eternally secured.
