1 Corinthians 11:25-26, 33

In the same way, after supper he took the cup, saying, “This cup is the new covenant in my blood; do this, 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.

So then, my brothers and sisters, when you gather to eat, you should all eat together.
