For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread, and when he had given thanks, he broke it and said, “This is my body, which is for you; do this in remembrance of me 1 Corinthians 11:23-24

“This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me.” 1 Corinthians 11:25

For I received from the Lord what I also passed on to you: 1 Corinthians 11:23

whenever you drink it, in remembrance of me.” For whenever you eat this bread and drink this cup, you proclaim the Lord’s death until he comes. 1 Corinthians 11:25-26

So then, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord. Everyone ought to examine themselves before they eat of the bread and drink from the cup. For those who eat and drink without discerning the body of Christ eat and drink judgment on themselves. That is why many among you are weak and sick, and a number of you have fallen asleep… 1 Corinthians 11:27-30

So then, my brothers and sisters, when you gather to eat, you should all eat together. Anyone who is hungry should eat something at home, so that when you meet together it may not result in judgment. 1 Corinthians 11:33-34
