1 Corinthians 11:23-27

The teaching I gave you is the same teaching I received from the Lord: On the night when the Lord Jesus was handed over to be killed, he took bread and gave thanks for it. Then he broke the bread and said, “This is my body; it is for you. Do this to remember me.” In the same way, after they ate, Jesus took the cup. He said, “This cup is the new agreement that is sealed with the blood of my death. When you drink this, do it to remember me.” Every time you eat this bread and drink this cup you are telling others about the Lord’s death until he comes. So a person who eats the bread or drinks the cup of the Lord in a way that is not worthy of it will be guilty of sinning against the body and the blood of the Lord.
