1 Corinthians 11:25-26, 33

In the same way, after they ate, Jesus took the cup. He said, “This cup is the new agreement that is sealed with the blood of my death. When you drink this, do it to remember me.” Every time you eat this bread and drink this cup you are telling others about the Lord’s death until he comes.

So my brothers and sisters, when you come together to eat, wait for each other.
