But you just proved how confusing Jesus' teaching could be without the proper background. For the disciples of Jesus, they were simple people: uneducated mostly, fishermen, farmers, village people, etc They didn't know their bible. They were operating mostly out of recognizing Jesus' heart and that he had the power to do miracles. Of course, after 2,000 years of "hindsight" it appears odd that they didn't get it.  Whoever eats my flesh and drinks my blood remains in me, and I in them  Literally? See, that's my point. Jesus is speaking symbolically, all the while making contextual references to Scripture and the prophets.  kneejerk response  Yes, be careful. Without the grace of God, there go I.
