Thematic Bible: What cannot have communion together

Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness? And what concord hath Christ with Belial? or what part hath he that believeth with an infidel? And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath 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 fellowship with demons. Ye cannot drink the cup of the Lord, and the cup of demons: ye cannot be partakers of the Lord's table, and of the table of demons.
