When Jesus instituted the Lord’s Supper, he said, “This [bread] is my body, which is given for you. Do this in remembrance of me” (Luke 22:19) and, “This cup that is poured out for you is the new covenant in my blood” (22:20). And so the bread and cup (or wine) represent his body and blood, which he gives as a sacrifice to inaugurate “the new covenant.”
In John 6, Jesus feeds five-thousand. Later in that chapter, he underscores the reality that the sign of the feeding points towards. He says, “Truly, truly, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Whoever feeds on my flesh and drinks my blood has eternal life, and I will raise him up on the last day” (John 6:53–54).
Do Jesus’ words here refer to the Lord’s Supper? After all, he offers his body and blood for eternal life here much like he does in Luke 22. Not quite. The difference is that Jesus offers the communication of his flesh in John 6 while he institutes the Lord’s Supper in Luke 22. [Read more…] about Does John 6 Speak about the Lord’s Supper?
