1 Corinthians 11:23-26

Let me go over with you again exactly what goes on in the Lord’s Supper and why it is so centrally important. I received my instructions from the Master himself and passed them on to you. The Master, Jesus, on the night of his betrayal, took bread. Having given thanks, he broke it and said, This is my body, broken for you. Do this to remember me. After supper, he did the same thing with the cup: This cup is my blood, my new covenant with you. Each time you drink this cup, remember me. What you must solemnly realize is that every time you eat this bread and every time you drink this cup, you reenact in your words and actions the death of the Master. You will be drawn back to this meal again and again until the Master returns. You must never let familiarity breed contempt.
