“and when he had give thanks, he broke it, and said, ‘This is my body which is for you. Do this in remembrance of me.’ In the same way also he took the cup, after supper, saying, ‘This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me'” (1 Cor. 11:24-25).
“Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of profaning the body and blood of the Lord” (1 Cor. 11:27).
