For thirty, forty, fifty years, I have resisted to the best of my powers the spirit of Liberalism in religion. Never did Holy Church need champions against it more sorely than now, when, alas! it is an error overspreading, as a snare, the whole earth; and on this great occasion, when it is natural for one who is in my place to look out upon the world, and upon Holy Church as in it, and upon her future, it will not, I hope, be considered out of place, if I renew the protest against it which I have made so often.
Liberalism in religion is the doctrine that there is no positive truth in religion, but that one creed is as good as another, and this is the teaching which is gaining substance and force daily.
It is inconsistent with any recognition of any religion, as true. It teaches that all are to be tolerated, for all are matters of opinion.
