Thematic Bible: What cannot have communion together

Be not unequally yoked with unbelievers: for what fellowship have righteousness and iniquity? or what communion hath light with darkness? And what concord hath Christ with Belial? or what portion hath a believer with an unbeliever? And what agreement hath a temple of God with idols? for we are a temple of the living God; even as God said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people.

But I say , that the things which the Gentiles sacrifice, they sacrifice to demons, and not to God: and I would not that ye should have communion with demons. Ye cannot drink the cup of the Lord, and the cup of demons: ye cannot partake of the table of the Lord, and of the table of demons.
