Let me help you. Metaphor:
“1. a figure of speech in which a term or phrase is applied to something to which it is not literally applicable in order to suggest a resemblance, as in “A mighty fortress is our God.” Compare mixed metaphor, simile (def. 1).
2. something used, or regarded as being used, to represent something else; emblem; symbol.”
“Jesus on Mt. Tabor is obviously a metaphor” - NOT.
“and when Gen 11:5 says that God came down to see [sic] the city being built” - not a metaphor, but not an uncommon way of speaking, as when I say I discovered riding horses.
Thank you for the lesson. It is really amazing that you can say with a straight face that Jesus dind't mean it literally when he said "eat, this is my body..." but you have no problem with the Bible says basically God is "uninformed" (and has to go and see, so he may know) and simply rationalize it as "uncommon way of speaking.
"Now, you insist that "eat, this is my body" is a metaphor. A metaphor for what? His "spiritual body?" Jesus never talks about spiritual bodies. That is yet another one of Pauline innovations! (1 Cor 15:44) No one else in the whole New Testament speaks of "spiritual bodies" except on-again-off-again Gnostic Paul.
I am not sure what he was thinking when he said "it is sown a natural body, it is raised a spiritual body" (I guess you had to be there or something). "Spiritual bodies" is a Gnostic concept. Chrsitianity teaches physical resurrection. That was demonstrated in John's Gospel when Thomas placed his fingers into Jesus' wounds.
When Jesus said to the crowd that they must eat his body, the Jewish crowed was grossed out and all but the Twelve left him. The Jews took it literally and Jesus did not try to stop them by "explaining" it was really his "spiritual body."
