I Corinthians 11:27

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 he disobeys Christ's express command to partake of both. If we do not partake of the sacramental symbol of the Lord's death worthily, we share in the guilt of that death. (Compare "crucify to themselves the Son of God afresh," Heb 6:6). Unworthiness in the person, is not what ought to exclude any, but unworthily communicating: However unworthy we be, if we examine ourselves so as to find that we penitently believe in Christ's Gospel, we may worthily communicate.

In this chapter the apostle blames, and endeavours to rectify, some great indecencies and manifest disorders in the church of Corinth; as, I. The misconduct of their women (some of whom seem to have been inspired) in the public assembly, who laid by their veils, the common token of subjection to their husbands in that part of the world. This behaviour he reprehends, requires them to keep veiled, asserts the superiority of the husband, yet so as to remind the husband that both were made for mutual help and comfort (v. 1-16). II. He blames them for their discord and neglect and contempt of the poor, at the Lord's supper (Co1 11:17-22). III. To rectify these scandalous disorders, he sets before them the nature and intentions of this holy institution, directs them how they should attend on it, and warns them of the danger of a conduct to indecent as theirs, and of all unworthy receiving (Co1 11:23 to the end).

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).
