“The preservation of freedom calls for the cultivation of virtue, self-discipline, sacrifice for the common good and a sense of responsibility towards the less fortunate. It also demands the courage to engage in civic life and to bring one’s deepest beliefs and values to reasoned public debate. In a word, freedom is ever new. It is a challenge held out to each generation, and it must constantly be won over for the cause of good (cf. Spe Salvi, 24).”
“Few have understood this as clearly as the late Pope John Paul II. In reflecting on the spiritual victory of freedom over totalitarianism in his native Poland and in eastern Europe, he reminded us that history shows, time and again, that “in a world without truth, freedom loses its foundation”, and a democracy without values can lose its very soul (cf. Centesimus Annus, 46). Those prophetic words in some sense echo the conviction of President Washington, expressed in his Farewell Address, that religion and morality represent “indispensable supports” of political prosperity.” (Pope Benedict XVI, Address at the White House, 2008)
“[C]onstitutional limits should be set to the powers of government, in order that there may be no encroachment on the rightful freedom of the person and of associations. This demand for freedom in human society chiefly regards the quest for the values proper to the human spirit. It regards, in the first place, the free exercise of religion in society.” (Second Vatican Council, Dignatatis humanae 1)
Thu, only by protecting Freedom of Conscience––religious conscience, political conscience, and the freedom to express that conscience in speech, alone or in association with others, can other freedoms be preserved. If a government can command what we think, believe, speak and with whom we associate in order to do it, it can command or forbid anything whatsoever.
