How does Luke 22:20 relate to the concept of atonement? Verse Text “Likewise He took the cup after supper, saying, ‘This cup is the new covenant in My blood, which is poured out for you.’” (Luke 22:20) Canonical and Historical Context Luke situates the words over the cup at the climactic moment of the Passover meal. By using covenant language, he places Jesus’ death within Israel’s redemptive story, linking Exodus sacrifice, prophetic expectation, and the inauguration of God’s kingdom through the Messiah. Passover Roots and Covenant Blood • Exodus 12:13 records the Passover lamb’s blood protecting Israel from judgment. • In Exodus 24:8 “Moses took the blood, sprinkled it on the people, and said, ‘Behold, the blood of the covenant….’” Jesus echoes this formula verbatim, replacing animal blood with His own. • Jewish liturgy still designates the third Passover cup as “the cup of blessing” or “redemption,” the point in the meal when Luke places Jesus’ words. Contemporary Qumran texts (4Q252) show that first-century Jews already associated covenant renewal with Passover, highlighting the natural bridge Luke employs. Sacrificial Background: Levitical Atonement Leviticus 17:11 states, “the life of the flesh is in the blood, and I have given it to you … to make atonement for your souls.” Atonement involves life-for-life substitution and purification. Jesus’ phrase “poured out” (ekchunnomenon) deliberately parallels Septuagint wording for sacrificial libations (e.g., Leviticus 4:7 LXX), identifying His impending death as the true sin offering. New Covenant Promised: Prophetic Anticipation Jeremiah 31:31-34 and Ezekiel 36:25-27 promise a new covenant characterized by inward transformation and forgiveness. Luke uses Jeremiah’s exact covenant terminology (“new covenant”) and thus portrays the cross as the legal enactment of that prophetic promise. Zechariah 9:11 adds, “Because of the blood of the covenant, I will release your prisoners,” foreshadowing liberation through a sacrificial death. Substitutionary Language: “Poured Out for You” The preposition huper (“for/on behalf of”) conveys substitution and benefit for specific people, not mere example. Isaiah 53:5-6,12 prophesies that the Servant would be “pierced for our transgressions … He bore the sin of many.” Jesus appropriates that Servant role; Luke later applies Isaiah 53:12 explicitly (Luke 22:37). Synoptic and Pauline Parallels Matthew 26:28 adds “for the forgiveness of sins,” clarifying the atonement purpose. Mark 14:24 uses “poured out for many.” Paul quotes the Lucan form directly in 1 Corinthians 11:25, affirming that earliest Gentile churches understood the Supper as proclamation of atonement (1 Corinthians 11:26; cf. Romans 3:25; 5:9; Ephesians 1:7; Colossians 1:14,20). Hebrews and the Heavenly Sanctuary Hebrews 9:12-22 develops Luke 22:20’s covenant logic: Christ entered “the greater and more perfect tabernacle … by His own blood” establishing an “eternal redemption.” The writer cites Exodus 24:8 verbatim, demonstrating that Luke’s wording precisely matches the Mosaic pattern now fulfilled. Archaeological and Extrabiblical Corroboration • Ketef Hinnom silver scrolls (7th-cent. BC) preserve priestly blessing language later echoed in Luke 1:68-79, evidencing textual stability of covenant motifs. • First-century ossuary of “Joseph son of Caiaphas” (S. Rocca, 2016) corroborates the priestly family involved in Jesus’ trial, anchoring the passion narrative. • A plaster inscription in the Cenacle (4th-cent.) bears the phrase “O Cup of the New Covenant,” indicating early Christian memory of the upper-room site. Theological Dimensions of Atonement in Luke 22:20 Penal Substitution Jesus identifies His blood as the covenant ratifying sacrifice that averts wrath and secures forgiveness. “Poured out for you” signals vicarious penalty-bearing, satisfying divine justice (Romans 3:25-26). Covenantal Mediatorship As Moses mediated the Sinai covenant with blood, Christ mediates a superior covenant (Hebrews 8:6). Luke’s wording assigns Jesus both priestly and victim roles, fulfilling Exodus 24 and Psalm 110 simultaneously. Ransom/Redemption Blood language implies payment (cf. 1 Peter 1:18-19; Revelation 5:9). Luke’s earlier statement that the Son of Man “came to give His life as a ransom” (parallel Mark 10:45) finds liturgical expression in the cup. Christus Victor The covenant inauguration also signals victory over enslaving powers. Zechariah’s promise of release and Colossians 2:15’s triumph blend with Luke’s covenant cup to present the cross as both payment and conquest. Liturgical and Ecclesial Application The Lord’s Supper functions as a perpetual proclamation of atonement. Early sources—Didache 9-10, Ignatius Smyrn. 7—stress that participation in the cup affirms belief in Christ’s sacrificial flesh and blood. For two millennia, churches have recited Luke 22:20 whenever they break bread, embedding atonement doctrine in worship practice. Concluding Synthesis Luke 22:20 crystallizes atonement by presenting Jesus’ impending death as covenant-ratifying, substitutionary, redemptive, and victorious. It draws on Passover, Sinai, prophetic promise, and Levitical sacrifice, is textually secure, historically situated, and perpetually reenacted in the Eucharist. The verse therefore stands as a concise, authoritative statement of how the Messiah’s shed blood secures forgiveness and reconciles humanity to God. |
