A society is a group of persons bound together organically by a principle of unity that goes beyond each one of them. As an assembly that is at once visible and spiritual, a society endures through time: it gathers up the past and prepares for the future. By means of society, each man is established as an "heir" and receives certain "talents" that enrich his identity and whose fruits he must develop. He rightly owes loyalty to the communities of which he is part and respect to those in authority who have charge of the common good.
