MSB(i)
16 Is not the cup of blessing that we bless a participation in the blood of Christ? And is not the bread that we break a participation in the body of Christ?
17 Because there is one loaf, we who are many are one body; for we all partake of the one loaf.
18 Consider the people of Israel: Are not those who eat the sacrifices fellow partakers in the altar?
19 Am I suggesting, then, that an idol is anything, or that food sacrificed to an idol is anything?
20 No, but the sacrifices of pagans are offered to demons, not to God. And I do not want you to be participants with demons.
21 You cannot drink the cup of the Lord and the cup of demons too; you cannot partake in the table of the Lord and the table of demons too.
