I rely on the words of Christ, "this is my body."  He didn't say: "this will be my body when it touches your tongue."  
The thing about Faith is that it doesn't depend on the physical sciences for proof, and why would it, being in the realm of the spiritual, the existence of which can't be proven either.  Can you prove that Jesus rose from the dead?  Or that He walked on water?  Cured the blind? Healed the sick?  Of course you can't.  If you accept that Christ and the Apostles performed miracles, you do so by faith alone.
What you deem "magical" thinking could just as easily be applied to you.  Is your tongue magic?  Is your tongue miraculous?  The only thing you've proven is that you lack faith and the intellectual honesty to admit you do not believe as the Church teaches.  Spare us what you wrongfully believe is profound; nothing you've ever stated passes the slightest scrutiny.
