1 Corinthians 11:23-29

23For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread, 24and when he had given thanks, he broke it and said, “This is my body, which is for you; do this in remembrance of me.” 25In the same way, after supper he took the cup, saying, “This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me.” 26For whenever you eat this bread and drink this cup, you proclaim the Lord’s death until he comes. 27So then, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord. 28Everyone ought to examine themselves before they eat of the bread and drink from the cup. 29For those who eat and drink without discerning the body of Christ eat and drink judgment on themselves.
