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.
22 Shall we thus provoke the Lord to jealousy and anger and indignation? Are we stronger than He [that we should defy Him]? [Deut. 32:21; Eccl. 6:10; Isa. 45:9.]
