1 Corinthians 11:23-28

23For I received from the Lord that which I also delivered to you: that the Lord Jesus on the same night in which He was betrayed took bread;

24and when He had given thanks, He broke it and said, “Take, eat; this is My body which is broken for you; do this in remembrance of Me.”

25In the same manner He also took the cup after supper, saying, “This cup is the new covenant in My blood. This do, as often as you drink it, in remembrance of Me.”

26For as often as you eat this bread and drink this cup, you proclaim the Lord’s death till He comes.

27Therefore whoever eats this bread or drinks this cup of the Lord in an unworthy manner will be guilty of the body and blood of the Lord.

28But let a man examine himself, and so let him eat of the bread and drink of the cup.
