  Some personalists note that man’s social nature and his vocation to inter-personal communion are not the same thing. Their capacity for rational community and friendship is one of the things that make human beings social. But the person’s capacity for communion is according to these personalists deeper than mere sociability. “Society,” in fact, is sometimes analogously applied to non-personal beings that live and interact as a group rather than in isolation from one another, whereas the word ‘communion’ could never be understood in this way. Communio does not simply refer to something common, but rather to a mode of being and acting in common through which the persons involved mutually confirm and affirm one another, a mode of being and acting that promotes the personal fulfillment of each of them by virtue of their mutual relationship. This mode of being and acting is an exclusive property of persons.
