Thematic Bible: What cannot have communion together

Don't be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness? What agreement has Christ with Belial? Or what portion has a believer with an unbeliever? What agreement has a temple of God with idols? For you 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 will be my people."

But I say that the things which the Gentiles sacrifice, they sacrifice to demons, and not to God, and I don't desire that you would have fellowship with demons. You can't both drink the cup of the Lord and the cup of demons. You can't both partake of the table of the Lord, and of the table of demons.
