It's like creation

My son Christopher, age seven, has been in the atrium for four years.  He mentioned on the drive home that he had been doing the preparation of the chalice.  I asked him what he thought "the mystery of the water and wine" meant.  (I was thinking it meant that we are so small, and God is so great.)  But Christopher said, "It's like creation:  the water is the people, and the wine is Jesus and God.  When everything was prepared in the world, people came last, just like the water is added last after the wine is prepared."    I asked the other catechists whether any of them might have presented this idea to Christopher, but they hadn't -- he came up with it himself.
