1 Corinthians 11:27
Therefore, whoever eats the [Lord's] bread or drinks from the Lord's cup in a way that is unworthy [of them. See verse 21], will be guilty of [dishonoring] the body and the blood of the Lord.
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].
