Passage
The cup of blessing which we bless, is it not [the] communion of the blood of the Christ? The bread which we break, is it not [the] communion of the body of the Christ?
The cup of blessing which we bless, is it not [the] communion of the blood of the Christ? The bread which we break, is it not [the] communion of the body of the Christ?
1 Corinthians 10:14 Wherefore, my beloved, flee from idolatry.
1 Corinthians 10:15 I speak as to intelligent [persons]: do *ye* judge what I say.
1 Corinthians 10:16 The cup of blessing which we bless, is it not [the] communion of the blood of the Christ? The bread which we break, is it not [the] communion of the body of the Christ?
1 Corinthians 10:17 Because we, [being] many, are one loaf, one body; for we all partake of that one loaf.
1 Corinthians 10:18 See Israel according to flesh: are not they who eat the sacrifices in communion with the altar?
The verse centers on "blessing", "communion", "blood", "christ", "bread", and "break". It is saying that the verse draws attention to "blessing" and "communion", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 15's "I speak as to intelligent persons do..." into verse 17's "Because we being many are one loaf...", so "blessing" and "communion" belong inside that flow. In 1 Corinthians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "blessing" and "communion" with trust shaped by these words, not by a vague optimism outside the passage.
