1 Corinthians 11:23-25

I have handed down to you what came to me by direct revelation from the Lord himself. The same night in which he was handed over, he took bread and gave thanks. Then he distributed it to the disciples and said, “Take it and eat your fill. It is my body, which is given for you. Do this to remember me.” He did the same with the cup of wine after supper and said, “This cup seals the new covenant with my blood. Drink it—and whenever you drink this, do it to remember me.”
