Thematic Bible: What cannot have communion together

Do not be unequally yoked with unbelievers [do not make mismated alliances with them or come under a different yoke with them, inconsistent with your faith]. For what partnership have right living and right standing with God with iniquity and lawlessness? Or how can light have fellowship with darkness? What harmony can there be between Christ and Belial [the devil]? Or what has a believer in common with an unbeliever? What agreement [can there be between] a temple of God and idols? For we are the temple of the living God; even as God said, I will dwell in and with and among them and will walk in and with and among them, and I will be their God, and they shall be My people.

No, I am suggesting that what the pagans sacrifice they offer [in effect] to demons (to evil spiritual powers) and not to God [at all]. I do not want you to fellowship and be partners with diabolical spirits [by eating at their feasts]. You cannot drink the Lord's cup and the demons' cup. You cannot partake of the Lord's table and the demons' table.
