1 Corinthians 11:25-29

25After they had eaten supper, Jesus took a cup of wine. He spoke to his disciples again. He said, ‘This cup shows my blood that will pour out when I die. God now makes a new agreement to save people because of my death. Whenever you drink from the cup in this way, do it to remember me.’

26Every time that you eat bread and you drink from the cup like this, you are showing something. You are showing people what the Lord's death means. You should continue to do this until he returns.

27Since that is true, you must be careful. Eat the bread and drink from the cup in a way that is right. Anyone who does not do that will be guilty. They are showing that they do not respect the Lord's body and his blood that he offered as a sacrifice.

28So everyone must think carefully about how they eat the bread and they drink from the cup.

29They must understand how important the Lord's body is. If anyone does not recognize this, God will punish them.
