1 Corinthians 11:23-26

23 After all, I passed on to you what I had received from the Lord. On the night he was betrayed, the Lord Jesus took bread
24 and spoke a prayer of thanksgiving. He broke the bread and said, "This is my body, which is given for you. Do this to remember me."
25 When supper was over, he did the same with the cup. He said, "This cup is the new promise made with my blood. Every time you drink from it, do it to remember me."
26 Every time you eat this bread and drink from this cup, you tell about the Lord's death until he comes.
