Fifty years ago today, on December 7, 1965, Pope Paul VI promulgated the Declaration on Religious Freedom (Dignitatis humanae). This document produced by the Second Vatican Council clarified the Catholic Church’s views on religious liberty, changed the way the Church interacted with states, and helped foster ecumenical relations with other faith traditions.

Since the release of Dignitatis humanae, the importance of defending religious freedom has e even more necessary. As Archbiship Charles J. Chaput has said, “In some ways, the [Declaration on Religious Freedom] is the Vatican II document that speaks most urgently to our own time. The reason is obvious. We see it right now in the suffering of Christians and other religious believers in many places around the world.”

Here are six key quotes from the document:

1. This freedom means that all men are to be immune from coercion on the part of individuals or of social groups and of any human power, in such wise that no one is to be forced to act in a manner contrary to his own beliefs, whether privately or publicly, whether alone or in association with others, within due limits. The council further declares that the right to religious freedom has its foundation in the very dignity of the human person as this dignity is known through the revealed word of God and by reason itself. This right of the human person to religious freedom is to be recognized in the constitutional law whereby society is governed and thus it is to e a civil right.

2. It is in accordance with their dignity as persons-that is, beings endowed with reason and free will and therefore privileged to bear personal responsibility-that all men should be at once impelled by nature and also bound by a moral obligation to seek the truth, especially religious truth. They are also bound to adhere to the truth, once it is known, and to order their whole lives in accord with the demands of truth. However, men cannot discharge these obligations in a manner in keeping with their own nature unless they enjoy immunity from external coercion as well as psychological freedom. Therefore the right to religious freedom has its foundation not in the subjective disposition of the person, but in his very nature. In consequence, the right to this immunity continues to exist even in those who do not live up to their obligation of seeking the truth and adhering to it and the exercise of this right is not to be impeded, provided that just public order be observed.

3. The freedom or immunity from coercion in matters religious which is the endowment of persons as individuals is also to be recognized as their right when they act munity. munities are a requirement of the social nature both of man and of religion itself. Provided the just demands of public order are observed, munities rightfully claim freedom in order that they may govern themselves according to their own norms, honor the Supreme Being in public worship, assist their members in the practice of the religious life, strengthen them by instruction, and promote institutions in which they may join together for the purpose of ordering their own lives in accordance with their religious principles.

4. The family, since it is a society in its own original right, has the right freely to live its own domestic religious life under the guidance of parents. Parents, moreover, have the right to determine, in accordance with their own religious beliefs, the kind of religious education that their children are to receive. Government, in consequence, must acknowledge the right of parents to make a genuinely free choice of schools and of other means of education, and the use of this freedom of choice is not to be made a reason for imposing unjust burdens on parents, whether directly or indirectly. Besides, the right of parents are violated, if their children are forced to attend lessons or instructions which are not in agreement with their religious beliefs, or if a single system of education, from which all religious formation is excluded, is imposed upon all.

5. [S]ociety has the right to defend itself against possible mitted on the pretext of freedom of religion. It is the special duty of government to provide this protection. However, government is not to act in an arbitrary fashion or in an unfair spirit of partisanship. Its action is to be controlled by juridical norms which are in conformity with the objective moral order. These norms arise out of the need for the effective safeguard of the rights of all citizens and for the peaceful settlement of conflicts of rights, also out of the need for an adequate care of genuine public peace, es about when men live together in good order and in true justice, and finally out of the need for a proper guardianship of public morality.

6. It is one of the major tenets of Catholic doctrine that man’s response to God in faith must be free: no one therefore is to be forced to embrace the Christian faith against his own will. This doctrine is contained in the word of God and it was constantly proclaimed by the Fathers of the Church. The act of faith is of its very nature a free act. Man, redeemed by Christ the Savior and through Christ Jesus called to be God’s adopted son, cannot give his adherence to God revealing Himself unless, under the drawing of the Father, he offers to God the reasonable and free submission of faith. It is pletely in accord with the nature of faith that in matters religious every manner of coercion on the part of men should be excluded. In consequence, the principle of religious freedom makes no small contribution to the creation of an environment in which men can without hindrance be invited to the Christian faith, embrace it of their own free will, and profess it effectively in their whole manner of life.
