  I am curious as to what you consider ..."evidence that the Apostles themselves believed in transubstantiation"... since the concept was quite foreign to them.
  
  Jesus' words in John's Gospel, in context, seem to be about being 'fed' on his words. He uses a number of metaphors in that passage, such as 'I am the manna come down from heaven' . The occasion was after the multiplication of loaves, way before the Last supper. We might apply it to that, but it does not mean that John's Gospel does.
  
  In the Gospels no one seems to have taken him 'literally'. No one carved up his body after death. They prepared it for burial. Nobody thought they were  supposed to nibble on his fingers or toes or carve him up into steaks.
  
  'Trans-substantiation' is fine if the philosophy makes sense to you. As for me, as far as I can figure that philosophy out, 'substance' is merely a conceptual 'reality' - there is nothing 'substantial' about it.
