What DID he say?
1 Corinthians 10:16
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?
1 Corinthians 11:25
In the same manner He also took the cup after supper, saying, This cup is the new covenant in My blood . This do, as often as you drink it, in remembrance of Me.
1 Corinthians 11:27
Therefore whoever eats this bread or drinks this cup of the Lord in an unworthy manner will be guilty of the body and blood of the Lord.
All about Communion, all about eating and drinking, all about blood.
