Libertas §0

⁰ To the Patriarchs, Primates, Archbishops, and Bishops of the Catholic World in Grace and Communion with the Apostolic See. Liberty, the highest of natural endowments, being the portion only of intellectual or rational natures, confers on man this dignity - that he is "in the hand of his counsel"(1) and has power over his actions. But the manner in which such dignity is exercised is of the greatest moment, inasmuch as on the use that is made of liberty the highest good and the greatest evil alike depend. Man, indeed, is free to obey his reason, to seek moral good, and to strive unswervingly after his last end. Yet he is free also to turn aside to all other things; and, in pursuing the empty semblance of good, to disturb rightful order and to fall headlong into the destruction which he has voluntarily chosen. The Redeemer of mankind, Jesus Christ, having restored and exalted the original dignity of nature, vouchsafed special assistance to the will of man; and by the gifts of His grace here, and the promise of heavenly bliss hereafter, He raised it to a nobler state. In like manner, this great gift of nature has ever been, and always will be, deservingly cherished by the Catholic Church, for to her alone has been committed the charge of handing down to all ages the benefits purchased for us by Jesus Christ. Yet there are many who imagine that the Church is hostile to human liberty. Having a false and absurd notion as to what liberty is, either they pervert the very idea of freedom, or they extend it at their pleasure to many things in respect of which man cannot rightly be regarded as free.
