1 Corinthians 11:27

“Wherefore, etc.] Since this is the plain institution of the Lord’s supper, the form and manner of administering of it; and since the bread and wine in it are representations of the body and blood of Christ, and the design of the whole is to remember Christ, and show forth his death; it follows, that whosoever shall eat this bread, and drink this cup of the Lord unworthily, shall be guilty of the body and blood of the Lord. The bread and cup are called the bread and cup of the Lord; because ate and drank in remembrance of him, being symbols of his body and of his blood, though not they themselves; these may be eaten and drank “unworthily”, when they are eaten and drank by unworthy persons, in…”

“eat and drink--So one of the oldest manuscripts reads. But three or four equally old manuscripts, the Vulgate and CYPRIAN, read, "or." Romanists quote this reading in favor of communion in one kind. This consequence does not follow. Paul says, "Whosoever is guilty of unworthy conduct, either in eating the bread, or in drinking the cup, is guilty of the body and blood of Christ." Impropriety in only one of the two elements, vitiates true communion in both. Therefore, in the end of the verse, he says, not "body or blood," but "body and blood." Any who takes the bread without the wine, or the wine without the bread, "unworthily" communicates, and so "is guilty of Christ's body and blood"; for…”

“Wherefore - (ὥστε hōste). So that, or it follows from what has been said. If this be the origin and intention of the Lord’s Supper, then it follows that whoever partakes of it in an improper manner is guilty of his body and blood. The design of Paul is to correct their improper mode of observing this ordinance; and having showed them the true nature and design of the institution, he now states the consequences of partaking of it in an improper manner. Shall eat this bread - See 1 Corinthians 11:26. Paul still calls it bread, and shows thus that he was a stranger to the doctrine that the bread was changed into the very body of the Lord Jesus. If the papal doctrine of transubstantiation had…”

“Whosoever shall eat this bread unworthily - That is, in an unworthy, irreverent manner; without regarding either Him that appointed it, or the design of its appointment. Shall be guilty of profaning that which represents the body and blood of the Lord. 1 Corinthians 11:28”

“11:27 To take the Lord’s Supper without recognizing its significance or with unconfessed sin in one’s life is to take it unworthily (see 11:28-31). It is equivalent to sinning against the body and blood of the Lord himself; it treats his sacrificial death as trivial (cp. Heb 10:29).”
