Thematic Bible: What cannot have communion together

Be not unequally yoked together with unbelievers: for what fellowship has righteousness with lawlessness? What communion has light with darkness? What agreement has Christ with Belial? What connection has a believer with an unbeliever? What has a temple of God in common with one of idols? For you are the temple of the living God, as God has said: I will dwell in them, and walk among them; and I will be their God, and they shall be my people.

But I say, that the things which the Gen tiles sacrifice, they sacrifice to demons, and not to God. I do not wish you to be partakers with demons. You can not drink the cup of the Lord, and the cup of demons: you can not be partakers of the table of the Lord, and of the table of demons.
