And as to tolerance, it is surprising how far removed from the equity and prudence of the Church are those who profess what is called liberalism. For, in allowing that boundless license of which We have spoken, they exceed all limits, and end at last by making no apparent distinction between truth and error, honesty and dishonesty. And because the Church, the pillar and ground of truth, and the unerring teacher of morals, is forced utterly to reprobate and condemn tolerance of such an abandoned and criminal character, they calumniate her as being wanting in patience and gentleness, and thus fail to see that, in so doing, they impute to her as a fault what is in reality a matter for commendation. But, in spite of all this show of tolerance, it very often happens that, while they profess themselves ready to lavish liberty on all in the greatest profusion, they are utterly intolerant toward the Catholic Church, by refusing to allow her the liberty of being herself free. (Papal Writings, Libertas, 1888).
2. Such doctrines as these having been scattered far and wide, so great a license of thought and action having sprung up on all sides, it is no matter for surprise that men of the lowest class, weary of their wretched home or workshop, are eager to attack the homes and fortunes of the rich; it is no matter for surprise that already there exists no sense of security either in public or private life, and that the human race should have advanced to the very verge of final dissolution. (Papal Encyclical, Quod Apostolici Muneris, 1878).
3. Only in freedom can man direct himself toward goodness. Our contemporaries make much of this freedom and pursue it eagerly; and rightly to be sure. Often however they foster it perversely as a license for doing whatever pleases them, even if it is evil. For its part, authentic freedom is an exceptional sign of the divine image within man. (Second Vatican Council, Gaudium et Spes, 1965).
