Christianity is not something purely spiritual, something only
subjective, emotional, of the will, of ideas; it is a cosmic reality.
God is the Creator of all matter, matter enters Christianity, and it is
only in this great context of matter and spirit together that we are
Christians. It is therefore very important that matter be part of our
faith, that the body be part of our faith; faith is not purely
spiritual, but this is how God inserts us into the whole reality of the
cosmos and transforms the cosmos, draws it to himself.
