For I received from the Lord what I also passed on to you: On the night when he was betrayed, the Lord Jesus took bread, and when he had given thanks, broke it, and said, “This is my body, which is for you. Do this in remembrance of me.”
In the same way also he took the cup, after supper, and said, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.” For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes.
So then, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sin against the body and blood of the Lord. Let a person examine himself; in this way let him eat the bread and drink from the cup. For whoever eats and drinks without recognizing the body, eats and drinks judgment on himself.
