Thematic Bible: What cannot have communion together

Be not diversely yoked with unbelievers; for what participation is there between righteousness and lawlessness? or what fellowship of light with darkness? and what consent of Christ with Beliar, or what part for a believer along with an unbeliever? and what agreement of God's temple with idols? for ye are the living God's temple; according as God has said, I will dwell among them, and walk among them; and I will be their God, and they shall be to me a people.

But that what the nations sacrifice they sacrifice to demons, and not to God. Now I do not wish you to be in communion with demons. Ye cannot drink the Lord's cup, and the cup of demons: ye cannot partake of the Lord's table, and of the table of demons.
