1 Corinthians 10:16 ESV
The cup of blessing that we bless, is it not a participation in the blood of Christ? The bread that we break, is it not a participation in the body of Christ?

You cannot drink the cup of the Lord and the cup of demons. You cannot partake of the table of the Lord and the table of demons.
