15 I am speaking as to intelligent (sensible) men. Think over and make up your minds [for yourselves] about what I say. [I appeal to your reason and your discernment in these matters.]
16 The cup of blessing [of wine at the Lord's Supper] upon which we ask [God's] blessing, does it not mean [that in drinking it] we participate in and share a fellowship (a communion) in the blood of Christ (the Messiah)? The bread which we break, does it not mean [that in eating it] we participate in and share a fellowship (a communion) in the body of Christ?
17 For we [no matter how] numerous we are, are one body, because we all partake of the one Bread [the One Whom the communion bread represents].
18 Consider those [physically] people of Israel. Are not those who eat the sacrifices partners of the altar [united in their worship of the same God]? [Lev. 7:6.]
19 What do I imply then? That food offered to idols is [intrinsically changed by the fact and amounts to] anything or that an idol itself is a [living] thing?
20 No, I am suggesting that what the pagans sacrifice they offer [in effect] to demons (to evil spiritual powers) and not to God [at all]. I do not want you to fellowship and be partners with diabolical spirits [by eating at their feasts]. [Deut. 32:17.]
21 You cannot drink the Lord's cup and the demons' cup. You cannot partake of the Lord's table and the demons' table.
