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." 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. - 1 Cor, 11:23-26
On the first day of the week we came together to break bread... - Acts 20.7
