Man has been compelled to submit to a conception of reality imposed on him by coercion, and not reached by virtue of his own reason and the exercise of his own freedom. This principle must be overturned and total recognition must be given to the rights of the human conscience, which is bound only to the truth, both natural and revealed. The recognition of these rights represents the primary foundation of every authentically free political order.
No one can consider himself extraneous or indifferent to the lot of another member of the human family. No one can say that he is not responsible for the well-being of his brother or sister (Genesis 4:9, Luke 10:29-37, Matthew 25:31-46).
Since it is not an ideology, the Christian faith does not presume to imprison changing socio-political realities in a rigid schema, and it recognizes that human life is realized in history in conditions that are diverse and imperfect. Furthermore, in constantly reaffirming the transcendent dignity of the person, the Church's method is always that of respect for freedom.
But freedom attains its full development only by accepting the truth. In a world without truth, freedom loses its foundation and man is exposed to the violence of passion and to manipulation, both open and hidden. The Christian upholds freedom and serves it, constantly offering to others the truth which he has known (John 8:31-32), in accordance with the missionary nature of his vocation. While paying heed to every fragment of truth which he encounters in the life experience and in the culture of individuals and of nations, he will not fail to affirm in dialogue with others all that his faith and the correct use of reason have enabled him to understand.
Man's principal resource is man himself. His intelligence enables him to discover the earth's productive potential and the many ways in which human needs can be satisfied. It is his disciplined work in close collaboration with others that makes possible the creation of ever more extensive working communities which can be relied on to transform man's natural and human environments.
