The Simplicity of the Eucharist

At adoration this morning, while reading Aquinas' Summa Theologica, I had this thought.  Aquinas and Dante both showed how God is perfectly simple.  He is not composite, but one. 

Isn't the Eucharist a perfect symbol of this?  So when Jesus becomes bread & wine, wouldn't this carry symbology too?

I want to be clear: the Eucharist is not a symbol of Jesus, it is Jesus.  But
that he becomes bread is meant to teach us of God's ultimate simplicity.
