1 Corinthians 11:25-27

Haweis(i) 25 In like manner also he took the cup, after they had supped, saying, This cup is the new testament in my blood: this do, as often as ye drink it, in remembrance of me. 26 For as often as ye eat this bread, and drink this cup, ye do shew forth the death of the Lord till he come. 27 Wherefore, whosoever eateth of this bread, or drinketh the cup of the Lord unworthily, he is guilty of the body and blood of the Lord.
