Thematic Bible: What cannot have communion together

Do not be unequally yoked with unbelievers: for what fellowship does righteousness have with lawlessness? Or what communion does light have with darkness? And what accord has Christ with Belial? Or what does a believer have in common with an unbeliever? And what agreement does a temple of God have with idols? We are the temple of the living God. God said: I will dwell in them, and walk among them; and I will be their God, and they will be my people. (Leviticus 26:12) (Zechariah 8:8)

But I say, that the things that the nations sacrifice, they sacrifice to demons, and not to God. I do not want you to have fellowship with demons. You cannot drink the cup of Jehovah and the cup of demons. You cannot be partakers of the Jehovah's Table and of the table of demons. (Malachi 1:12)
