Sea breeze, I"m not rejecting anything. The bread and wine are only for the apostles in that room with him. The whole memorial thing is not for anyone today.
He said to keep doing this in remembrance of him. They did not have the books of Matthew, Mark, Luke & John to remember him by. They just had their memories. Like the passover was given in memory of their leaving Egypt, This passover was given in memory of Jesus passing over their sins.
But today we have the 4 books to remember him by. So instead of bread and wine, we reread the books in remembrance of him.
