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. --Pope Leo XIII, Libertas Praestantissimum, 1888
