1 Corinthians 11:23-28

23 For I pass on to you what I received from the Lord himself. On the night when he was betrayed, the Lord Jesus took some bread 24 and gave thanks to God for it. Then he broke it in pieces and said, “This is my body, which is given for you. Do this in remembrance of me.” 25 In the same way, he took the cup of wine after supper, saying, “This cup is the new covenant between God and his people—an agreement confirmed with my blood. Do this in remembrance of me as often as you drink it.” 26 For every time you eat this bread and drink this cup, you are announcing the Lord’s death until he comes again.

27 So anyone who eats this bread or drinks this cup of the Lord unworthily is guilty of sinning against the body and blood of the Lord. 28 That is why you should examine yourself before eating the bread and drinking the cup.

1 John 1:9

9 But if we confess our sins to him, he is faithful and just to forgive us our sins and to cleanse us from all wickedness.

1 Corinthians 10:17

17 And though we are many, we all eat from one loaf of bread, showing that we are one body.

Revelation 3:20

20 “Look! I stand at the door and knock. If you hear my voice and open the door, I will come in, and we will share a meal together as friends.
