1 Corinthians 11:23-26

For I received from the Lord that which I also delivered to you; that the Lord Jesus on the same night He was betrayed took bread:
and when, He had given thanks, He broke it and said, “Take, eat, this is My body which is broken for you; do this in remembrance of Me.”
In the same manner He also took the cup after supper, saying, “This cup is the new covenant in My blood. This do as often as you drink it, in remembrance if Me.”
For as often as you eat this bread and drink this cup, you proclaim the Lord’s death till He comes.
*When we are at church we do this as a thankful reminder for what Jesus has done for us.
