The statement that a human being is a soul and a body is not sufficient.
The way their union comes about in the mutual creation of one human being
is what matters. Moreover, the spiritual substance of a human being has
a different structure than the material substance, yet there is some similarity,
indeed something in common. The most difficult issue refers to the
existence of the spiritual element in the body, which unites it with the soul
and creates the human body out of it. The combination of body and soul, as
well as the human community, has its structure. Individual human beings
and communities are engrafted in the life of the Triune God. The substantial
structure of a human being constitutes the foundation of the social structure
and coherent wholeness with the structure of life of the Divine Persons.
