The New Covenant cup: 'Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.' After instituting the bread, Jesus took 'the cup after supper' (τὸ ποτήριον... μετὰ τὸ δειπνῆσαι, to potērion... meta to deipnēsai), declaring: 'This cup is the new testament in my blood' (Τοῦτο τὸ ποτήριον ἡ καινὴ διαθήκη ἐν τῷ αἵματί μου, Touto to potērion hē kainē diathēkē en tō haimati mou). The term 'testament' (διαθήκη, diathēkē) means covenant. Jesus institutes a 'new covenant' prophesied in Jeremiah 31:31-34, ratified by His blood 'which is shed for you' (τὸ ὑπὲρ ὑμῶν ἐκχυννόμενον, to hyper hymōn ekchynnomenon, poured out on your behalf). The Old Covenant at Sinai was ratified with animal blood (Exodus 24:8); the New Covenant is ratified with Christ's blood. This is the heart of the gospel: Christ's substitutionary death establishes relationship with God.
Historical Context
The Last Supper occurred during Passover, when Jews remembered deliverance from Egypt through the lamb's blood (Exodus 12). Jesus reinterprets Passover through Himself—He is the true Lamb whose blood delivers from sin and death. The 'new covenant' fulfills Jeremiah's prophecy of internal transformation, written law on hearts, universal knowledge of God, and complete forgiveness (Jeremiah 31:31-34). Hebrews 8-10 extensively develops how Christ's once-for-all sacrifice surpasses the Old Covenant's repeated offerings. The Lord's Supper/Eucharist/Communion has been observed by Christians for 2,000 years, remembering Christ's death until He returns (1 Corinthians 11:26). This simple meal encapsulates the gospel: Christ's body broken and blood shed for sinners' salvation.
Questions for Reflection
How does Jesus' institution of the New Covenant fulfill Old Testament prophecy and typology?
What does it mean that the covenant is 'in my blood'—why was blood necessary?
How should regular observance of Communion shape Christian life and worship?
