1 Corinthians 10:16-17 The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ? For we, though many, are one bread and one body; for we all partake of that one bread.
2 Corinthians 6:14-18 Do not be unequally yoked together with unbelievers. For what fellowship has righteousness with lawlessness? And what communion has light with darkness? And what accord has Christ with Belial? Or what part has a believer with an unbeliever? And what agreement has the temple of God with idols? For you are the temple of the living God. As God has said: "I will dwell in them And walk among them. I will be their God, And they shall be My people." Therefore"Come out from among them And be separate, says the Lord. Do not touch what is unclean, And I will receive you." "Iwill be a Father to you, And you shall be Mysons and daughters, Says the LORD Almighty."
