“And He took bread, gave thanks and broke it, and gave it to them, saying, “This is My body which is given for you; do this in remembrance of Me.””
“Likewise He also took the cup after supper, saying, “This cup is the new covenant in My blood, which is shed for you.”
In 1838, the telegraph was invented by Samuel Morse. For the first time messages could be relayed from one place to another quickly and accurately. You didn’t need carrier pigeons, flags or a fast horse anymore, but electric impulses could be sent by trained operators over wires dedicated for that purpose. In its day, it was revolutionary; state-of-the-art stuff.
Jesus encodes spiritual lessons to his followers, and although the analogy isn’t perfect, he communicates what’s spiritual to the physical. He uses images–bread and wine, to explain salvation in ways that would’ve meant something to those who followed.
The lessons come from the feast of the Passover, Exodus 12 and Leviticus 23. Jesus reinterpreted them in Himself, and the focus was no longer on the suffering of Israel in Egypt, but on the ‘sin-bearing’ suffering of Jesus on their behalf. He was the “Lamb of God, who takes away the sin of the world! (John 1:29.)
The code is now fulfilled by Jesus.
The elements are tweaked (a great ‘theological” term, btw) and they mesh together quite well between the O.T. and the N.T. This meal was clearly communicated to Jesus’ followers–they knew exactly what he was saying–there would’ve been no ambiguity or confusion.
Jesus shares his imminent crucifixion, in common code–the bread and wine of the supper, to describe what was coming. From that point on, they would never forget that bread was now his “body,” and the wine had now become his “blood,” both broken, and shed respectively.
He explained that he was becoming their sacrifice–what he was going to do in a short span of a few hours was going to open up eternal life. Since then, a lot of theology has been discussed–transubstantiation, consubstantiation, or a memorial. You can toss in the idea of eucharistic prayer too. Books and books of each have been written. My library is loaded with them.
There seem to be merits for each concept, and I know that my own viewpoint won’t satisfy anyone at all. I’m sorry. But the critical issue for me is that the deed has been done. The code has been given, and eternal life has been given to us.
“What is certain is that Jesus bids us commemorate, not his birth, nor his life, nor his miracles, but his death.”
