The Greek noun deipnon refers to the main evening meal — the chief meal of the day in Greco-Roman society. It carried social significance as the setting for fellowship, hospitality, and important conversation. In the New Testament it appears in Jesus' parables about great banquets, in the Last Supper narratives, and in Paul's discussion of the Lord's Supper in 1 Corinthians 11.
The deipnon is central to the New Testament's theology of fellowship and eschatology. The parable of the Great Banquet (Luke 14:16–24) uses a deipnon to illustrate the kingdom invitation — one that the invited refuse and the outcasts accept. The Last Supper (deipnon) is the defining covenant meal of the new covenant. Paul's treatment of the Lord's Supper (1 Corinthians 11:20–34) shows how seriously God takes the integrity of this meal. Revelation 19:9 points to the ultimate deipnon — the Marriage Supper of the Lamb, the eschatological feast of God's redeemed family.
