We are delighted to welcome this little work, both for the sake of its own proper merits, and because it is the first instalment of the authorized translation of the admirable works of Mgr. de Segur. The Encyclical and Syllabus still continue to be the great event of the day. Indeed, as yet, we see only the beginnings of the influence it is surely destined to exercise on men’s minds; and for the due development of that influence, works like this of the French prelate are very necessary. The docile Catholic, for whom St. Peter lives and speaks in Pius IX., will find set forth herein the majesty and beauty of the doctrine he had before received in simple faith. The Catholic whose mind has been coloured for good and evil by modern ideas, and who has felt alarm at the apparent contradiction between the teaching of the Pope and certain social doctrines he has long held to be as sacred as first principles, will find in these pages wherewith to calm his apprehensions and steady his judgment He will see that what the Church condemns is already condemned by reason and history; and that, far from placing under the ban any of the elements of true progress, the Holy See censures the very errors which make all true progress impossible. The priest who has charge of the wise and the unwise together, will be glad to have, in these few pages, what may enable him to provide for the wants of both. We quote a few passages:— The Pope Condemns Liberty Of Conscience. You mean to say “the liberty of having no conscience”, or, what is much the same thing, “the liberty of corrupting or poisoning one’s conscience!” You are right; the Pope is the mortal enemy of a liberty so shocking. What good father would leave his son the liberty of poisoning himself? It was Protestantism which invented, and it is the Revolution which has perfected, what unbelievers call liberty of conscience. It has become an essential part of _progress_, of that anti-Catholic _progress_ of which we were speaking just now, and which has insinuated itself into all modern constitutions.... The liberty of following one’s conscience, even when it is misguided, is not the liberty of conscience condemned by the Encyclical Letter. Catholics, Protestants, Jews, and all men, of whatever denomination or sect they may be, are obliged to follow the dictates of their conscience; as long as they are misled _fairly_, it is but a misfortune; what the Church demands is that all men may escape this misfortune, and have full liberty of embracing truth, when once they have discovered it. The Pope condemns liberty of _conscience_, and not liberty of _consciences_. The one is very different from the other. In Condemning Liberty Of Worship, The Pope Wishes To Oblige Governments To Persecute Unbelievers, Protestants, Jews.
