I have always condemned Liberal Catholicism and I will condemn it again forty times over if it be necessary.
Pope Pius IXNow you know well that the most deadly foes of the Catholic religion have always waged a fierce war, but without success, against this Chair [of St. Peter]; they are by no means ignorant of the fact that religion itself can never totter and fall while this Chair remains intact, the Chair which rests on the rock which the proud gates of hell cannot overthrow and in which there is the whole and perfect solidity of the Christian religion.
Pope Pius IXThe Church is built on the rock of Peter, and he who eats the Lamb outside this holy dwelling is reprobate .. .He who eats the Lamb outside this Apostolic See has no part with God!
Pope Pius IX[Dr. Constain James] refuted so well the aberrations of Darwinism.... [A system] which is repugnant at once to history, to the tradition of all people, to exact science, to observed facts, and even to reason itself, would seem to need no refutation. But the corruption of this age, the machinations of the perverse, the danger of the simple, demand that such fancies, altogether absurd though they are, should - since they borrow the mask of science - be refuted by true science.
