I'm not going to go off on all of your tangents until you address what I already wrote.
My questions are not tangents. They are in John 6, which is the passage/topic of the discussion.
Do you still not understand the symbolism in Matthew 26:26-29?
What symbolism? Just come out and say which part is symbolic. The wine is wine. At no point is it symbolic. Fruit of the vine = wine. No symbolism. "He took the bread, blessed it, broke it, and gave it to His disciples," still no symbolism.
"Take eat; this is My Body." This is the first point at which one could even suggest symbolism. Yet, there is no clarification or distinction made by Christ, nor the author of the Gospel, that this was symbolic. Any time that Christ was being symbolic or metaphorical, it is clearly revealed or expounded upon as such. For example, in John 2:19, when Christ says "Destroy this temple and in three days I will raise it up." The Jews say "It has taken 46 years to build this temple, and will you raise it up in three days?" John immediately clarifies the statement with "But He spoke of the temple of His Body. When therefore He was raised from the dead...." (Notice no such clarification is given in the Last Supper accounts, nor John 6's Eucharistic passages). So why, would no Gospel writer give this clarification of symbolic metaphor, when they have done so every single time that Christ spoke in such a manner?
Back to Matthew 26; "For this is my blood of the covenant, which is poured out for many for the forgiveness of sins." If one part of this is symbolic, then the whole of it must be. If Christ's Blood is symbolic, how is it symbolically poured out for many for the forgiveness of sins? We know that Christ literally poured out His Blood for our forgiveness, right? So, His Blood must logically be literal, not metaphorical, in this passage. It makes no logical sense to switch back and forth between metaphor and literal meanings for "Blood."
So, logically, with knowledge of internal examples of clarification by the Gospel writers, it only stands to reason that Christ was speaking literally, not metaphorically.
Now, back to those questions you seem to be avoiding, despite their relevance to the conversation, taken directly from John 6.
1.) How is Christ's body and blood "true food and drink?"
2.) Why did the disciples leave Christ, if He was being symbolic? It clearly says that they thought He was being literal.
