1 Corinthians 10:21
you should not drink the cup of the Lord, and the cup of demons: you should not be partakers of the Lord's table, and of the table of demons.
but upon the king's coming in to see the guests, he observ'd one there without a wedding garment: and he said to him,
I am the living bread, that is come down from heaven: whosoever shall eat of this bread, shall live for ever: and the bread that I will give, is my flesh, which I will give for the life of the world.
I say not this of you all; for I know whom I have chosen: and that passage of the scripture must be fulfilled, "He that eateth bread with me, hath lift up his heel against me."
1 Corinthians 11:29
for he that eats and drinks in a disrespectful manner, not discriminating the Lord's body, eateth and drinketh to his own punishment.
