1 Corinthians 11:23-25

23After all, I passed on to you what I had received from the Lord. On the night he was betrayed, the Lord Jesus took bread

24and 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.”

25When 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.”
