1 Corinthians 11:25-27

New Century Version

²⁵ 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.” ²⁶ Every time you eat this bread and drink this cup you are telling others about the Lord’s death until he comes.

²⁷ 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.
