1 Corinthians 11:25-27

ACV(i) 25 Likewise also the cup after the supper, saying, This cup is the new covenant in my blood. This do, as often as ye drink it, for my memorial. 26 For as often as ye eat this bread and drink this cup, ye proclaim the Lord's death until he comes. 27 Therefore whoever may eat this bread or drink the cup of the Lord unworthily of the Lord, will be guilty of the body and the blood of the Lord.
