RCs tell us that we are to understand the eating the flesh and drinking the blood literally. Think about the position the RCs here are arguing. The unbelievers who left Jesus ... they were the ones who took the sayings of Jesus literally. The ones who responded "How can this man give us his flesh to eat ... " ... are the ones who walked away.
So the RCs here are in the embarrassing position of supporting the view of the unbelieving masses (no pun intended) who left.
Using catholic Magic Thinking, they will shift the scene on you, trying to take you away from what is an embarrassment to their heresy, over tot he legitimate scene the night before He went tot he Cross. But if you press the point of the Passover, they will immediately shift back to the specious reference from the year before. You can tell them that Jesus was using sarcasm to winnow the weak ones who would not be ‘down for the struggle’, but that only shifts their magic thinking to ‘do whatever he says, just do it.’ It is a lesson in what I’ve dubbed selective literalism. It is like jello and nails and walls, but only the Holy Spirit can break through the darkness with a flicker of Truth’s Light. And lest we forget, that is exactly why He command us to be about the family business, proclaiming the Gospel of His Grace offered to us in Jesus Christ.
Peter NEVER ASKED FOR THE BREAD...He said that Jesus had the WORDS of eternal life...not the bread
