Thematic Bible: What cannot have communion together

Be not unequally yoked with infidels; for what participation hath righteousness with unrighteousness? and what fellowship [is there] between light and darkness? and what concord of Christ with Belial? or what share hath he that believeth with an infidel? or what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, "I will inhabit in them, and walk about in them; and I will be their God, and they shall be for me a people."

But that what the Gentiles sacrifice, they sacrifice to daemons, and not to God: and I would not have you in communion with daemons. Ye cannot drink the cup of the Lord and the cup of daemons: ye cannot be partakers of the table of the Lord, and the table of daemons.
