You cannot drink the cup of the Lord and then go drink a cup that honors demons. You cannot share a meal at the Lord’s table and then go share a meal that honors demons.
The cup of blessing that we give thanks for is a sharing in the blood sacrifice of Christ, isn’t it? And the bread that we break is a sharing in the body of Christ, isn’t it?
In the same way, after supper, Jesus took the cup of wine and said, “This wine represents the new agreement from God to his people. It will begin when my blood is poured out for you.”
