1 Corinthians 11:20
So, when you people assemble together [Note: This was a church meeting at which they also shared a common meal prior to the Lord's Supper], it is not possible to eat the Lord's Supper [properly].
1 Corinthians 11:29
For a person who eats and drinks without determining the significance of the body [of Jesus], [i.e., without showing proper reverence for Christ, as represented by the bread and cup (see verse 27), or without distinguishing this sacred memorial Supper from a common meal], eats and drinks judgment upon himself. [Note: Some apply "the body" in this verse to the church and explain it as a warning against failing to appreciate the unity that the Supper is intended to signify].
Revelation 16:19
And the great city was split into three parts, and the cities of the nations were destroyed. And God remembered the great Babylon and made her drink from the cup of wine of His fierce anger.
