11 The People of God believes that it is led by the Lord's Spirit, Who fills the earth. Motivated by this faith, it labors to decipher authentic signs of God's presence and purpose in the happenings, needs and desires in which this People has a part along with other men of our age. For faith throws a new light on everything, manifests God's design for man's total vocation, and thus directs the mind to solutions which are fully human. This council, first of all, wishes to assess in this light those values which are most highly prized today and to relate them to their divine source. Insofar as they stem from endowments conferred by God on man, these values are exceedingly good. Yet they are often wrenched from their rightful function by the taint in man's heart, and hence stand in need of purification. What does the Church think of man? What needs to be recommended for the upbuilding of contemporary society? What is the ultimate significance of human activity throughout the world? People are waiting for an answer to these questions. From the answers it will be increasingly clear that the People of God and the human race in whose midst it lives render service to each other. Thus the mission of the Church will show its religious, and by that very fact, its supremely human character.
