1 Corinthians 11:25-27

American Standard Version

²⁵ In like manner also the cup, after supper, saying, This cup is the new covenant 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 the cup, ye proclaim the Lord’s death till he come. ²⁷ Wherefore whosoever shall eat the bread or drink the cup of the Lord in an unworthy manner, shall be guilty of the body and the blood of the Lord.
