The easiest solution...just trust in Jesus' words "This is my body" "This is my blood".
Eww, no, if it impies canibalism, no, Ive tried, but I cant believe that.
The lamb was slain. Without the shedding of blood there is no remission of sins.
When ppl were talking earlier about the lamb at the Seder, they mentioned it was a memorial...when God saw the blood, He passed over, right? (A remembrance of that past, one time act)
We as christians also know it was prophetic...not just looking back to Gods mercy, but pointing forward to the Lamb of God who would come to take away the sin of the world.
It was not so much about the eating of the lamb ... It was the slaying of the lamb, the shed blood and death, the sacrifice of the lamb that mattered.
Jesus is the Lamb slain from the foundation of the world.
If there was no lamb (on the platter) at the last supper, as someone said earlier, the Lamb was still there, because Jesus was with them.
As all the previous times prophecied towards the Lamb to come, this was the last one prophesying to it, as Jesus was about to be slain. (He still was with them, so it was still a prophecy)
So when He said take and eat, take and drink, He wasn't referring to literally eating and drinking Him, He was saying His body would be broken, His blood would be shed, 'the lamb slain', for the sins of the world...ON THE CROSS.
Just as they kept the passover in remembrance (a symbolic memorial/celebration) of the one time act of deliverance (back in Exodus),
we now share the bread and wine in remembrance of the one-time sacrifice of Jesus, slain for our sins.
It's not about us eating and drinking, it's about Jesus breaking and shedding His blood ... dying, for us.
It's a memorial/celebration.
Just like the passover...It's symbolic.
Beautifully symbolic.
