Just as the sacrament not only symbolizes, in sensible species, an operation of Grace, but is also the real presence of God, which it causes to occupy a fragment of space and communicates to those who eat of the consecrated bread, provided that they are inwardly prepared, in the same way the sensible has not only a motor and vital significance, but is nothing other than a certain way of being in the world suggested to us from some point in space, and seized and acted upon by our body, provided that it is capable of doing so, so that sensation is literally a form of communion.
