1 Corinthians 10:16; 1 Corinthians 10:21; 1 Corinthians 11:25-27
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?
Ye cannot drink the cup of the Lord, and the cup of devils: ye cannot be partakers of the Lord's table, and of the table of devils.
After the same manner also he took the cup, when he had supped , saying , This cup is the new testament in my blood: this do ye , as oft as ye drink it, in remembrance of me.
For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come .
Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord.
