In the same way, after supper, He took the cup of wine, saying, "This cup is the new covenant ratified by my blood. Whenever you drink it, do so in memory of me."

Is the cup of blessing which we bless [at the Lord’s Supper] not a sharing in the blood of Christ? [Indeed it is.] Is the bread which we break not a sharing in the body of Christ? [Indeed it is.]

It is not possible for you, at the same time, to take the cup of the Lord and the cup of evil spirits; you may not take part in the table of the Lord and the table of evil spirits.

For whenever you take the bread and the cup you give witness to the Lord's death till he comes.

If, then, anyone takes the bread or the cup of the Lord in the wrong spirit, he will be responsible for the body and blood of the Lord.

But let no man take of the bread and the cup without testing himself.

So, my dear brothers, continue to be firm, incapable of being moved, always letting the cup run over in the work of the Lord, because you know that your labor in the service of the Lord is never thrown away.

The cup of blessing which we bless, is it not the communion of the blood of Christ?

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].
