1 Corinthians 11:23-28 Holman Christian Standard Bible (HCSB)
23 For I received from the Lord what I also passed on to you: On the night when He was betrayed, the Lord Jesus took bread, 24 gave thanks, broke it, and said,[a] “This is My body, which is[b] for you. Do this in remembrance of Me.”
25 In the same way, after supper He also took the cup and said, “This cup is the new covenant established by My blood. Do this, as often as you drink it, in remembrance of Me.” 26 For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until He comes.
27 Therefore, whoever eats the bread or drinks the cup of the Lord in an unworthy way will be guilty of sin against the body[c] and blood of the Lord. 28 So a man should examine himself; in this way he should eat the bread and drink from the cup.
