The truth is a desire of the human person, the search for which always supposes the exercise of authentic freedom. Many, without a doubt, would prefer to take the easy way out, trying to avoid this task. Some, like Pontius Pilate, ironically question the possibility of even knowing what truth is (cf. Jn 18:38), claiming is incapable of knowing it or denying that there exists a truth valid for all. This attitude, as in the case of scepticism and relativism, changes hearts, making them cold, wavering, distant from others and closed. There are too many who, like the Roman governor, wash their hands and let the water of history drain away without taking a stand.
....Anyone who acts irrationally cannot become a disciple of Jesus. Faith and reason are necessary and complementary in the pursuit of truth. God created man with an innate vocation to the truth and he gave him reason for this purpose. Certainly, it is not irrationality but rather the yearning for truth which the Christian faith promotes. Each man and woman has to seek the truth and to choose it when he or she finds it, even at the risk of embracing sacrifices.
Furthermore, the truth which stands above humanity is an unavoidable condition for attaining freedom, since in it we discover the foundation of an ethics on which all can converge and which contains clear and precise indications concerning life and death, duties and rights, marriage, family and society, in short, regarding the inviolable dignity of the human person. This ethical patrimony can bring together different cultures, peoples and religions, authorities and citizens, citizens among themselves, and believers in Christ and non-believers.
Christianity, in highlighting those values which sustain ethics, does not impose, but rather proposes Christ’s invitation to know the truth which sets us free. The believer is called to offer that truth to his contemporaries, as did the Lord, even before the ominous shadow of rejection and the Cross. The personal encounter with the one who is Truth in person compels us to share this treasure with others, especially by our witness....
The right to freedom of religion, both in its private and in its public dimension, manifests the unity of the human person, who is at once a citizen and a believer. It also legitimizes the fact that believers have a contribution to make to the building up of society.
