1 Corinthians 11:25-27

Etheridge(i) 25 Likewise after they had supped he gave also the cup, and said, This cup is the new covenant in my blood; so do, whensoever you shall drink (it) to my remembrance. 26 For whensoever you eat this bread, and drink this cup, the death of our Lord you commemorate until his advent. 27 Whoever then eateth of the bread of the Lord, and drinketh of his cup, and is not worthy of it, is guilty of the blood of the Lord and of his body.
