are you quite sure that not being able to find scripture that says something is an impediment to your formulation of doctrine?
b/c i see that you've asserted several things that no scriptures say. things we also have heard many times before
but put this together with Exodus 14:14, remembering that Exodus 16:4 comes about because of the same transgression of Exodus 14:11, The Lie of Satan repeated in Exodus 16:3. and the bread is Christ and the peace is Christ. see John 6.
He Himself is our peace
(Ephesians 2:14)
