Thematic Bible: What cannot be partaken together

What do I mean then? That a thing sacrificed to idols is anything, or that an idol is anything? No, but I say that the things which the Gentiles sacrifice, they sacrifice to demons and not to God; and I do not want you to become sharers in demons. You cannot drink the cup of the Lord and the cup of demons; you cannot partake of the table of the Lord and the table of demons.
