While Jesus said He spoke vaguely...
Mr Blume, parables are not vague if you are not an idiot, and i seriously doubt that Christ was oblivious to the reaction that would be engendered by His declarations in
John 6, and was relying on the Apostles to clarify for Him, as you seem to be espousing. If you cannot reconcile your doctrine solely with Christ, i hate to break this to you, but we have Scripture for those too, and you are just painting yourself into another corner.
