23 For I received from the Lord the teaching that I passed on to you: that the Lord Jesus, on the night he was betrayed, took a piece of bread,
24 gave thanks to God, broke it, and said, “This is my body, which is for you. Do this in memory of me.”
25 In the same way, after the supper he took the cup and said, “This cup is God's new covenant, sealed with my blood. Whenever you drink it, do so in memory of me.”
26 This means that every time you eat this bread and drink from this cup you proclaim the Lord's death until he comes.
27 It follows that if anyone eats the Lord's bread or drinks from his cup in a way that dishonours him, he or she is guilty of sin against the Lord's body and blood.
28 So then, you should all examine yourselves first, and then eat the bread and drink from the cup.
29 For if people do not recognize the meaning of the Lord's body when they eat the bread and drink from the cup, they bring judgement on themselves as they eat and drink.
