1 Corinthians 10:16-21

For when we pray for the blessing of the communion cup, isn’t this our co-participation with the blood of Jesus? And the bread that we distribute, isn’t this the bread of our co-participation with the body of Christ? For although we’re many, we become one loaf of bread and one body as we feast together on one loaf. Consider the people of Israel when they fell into idolatry. When they ate the sacrifices offered to the gods, weren’t they becoming communal participants in what was sacrificed? Now, am I saying that idols and the sacrifices offered to them have any value? Absolutely not! However, I am implying that when an unbeliever offers a sacrifice to an idol, it is not offered to the true God but to a demon. I don’t want you to be participants with demons! You can’t drink from the cup of the Lord and the cup of demons. You can’t feast at the table of the Lord and feast at the table of demons.
