Dear Jim —
The Eucharist is the substance, the
individual nature, of the living
glorified Christ, with the accidents of
bread and wine. The accidents are
the physical properties and appearances,
everything that is known by the senses.
This is a miracle and a mystery.
When we consume meat, we consume
a dead creature for the physical
properties, the properties that are
known by the senses and that can
support the body.
When we receive the Eucharist, we
are communing with a living Person
through the medium (sacramental sign) of the accidents of bread and wine.
A cannibal destroys a human being
to consume the accidents of the body.
Cannibalism today is a diabolic upside-down
mockery of the Eucharist.
