Summary: On the night of His betrayal, Jesus established the Eucharist. Breaking bread, He offered it as His body, and the cup as the new covenant in His blood, instructing us to commemorate His sacrifice in this act until He comes again.
Brothers and sisters:
I received from the Lord what I also handed on to you, that the Lord Jesus, on the night he was handed over, took bread, and, after he had given thanks, broke it and said, “This is my body that is for you. Do this in remembrance of me.”
In the same way also the cup, after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.”
For as often as you eat this bread and drink the cup, you proclaim the death of the Lord until he comes.
