Thematic Bible: What cannot have communion together

Set yourselves therefore at large, and bear not a stranger's yoke with the unbelievers. For what fellowship hath righteousness with unrighteousness? What company hath light with darkness? What concord hath Christ with Belial? Either, what part hath he that believeth with an infidel? How agreeth the temple of God with images? And ye are the temple of the living God, as said God, "I will dwell among them, and walk among them, and will be their God: and they shall be my people."

Nay, but I say, that these things which the gentiles offer, they offer to devils, and not to God. And I would not that ye should have fellowship with the devils. Ye cannot drink of the cup of the Lord, and of the cup of the devils. Ye can not be partakers of the Lord's table, and of the table of devils.
