Part II

The Vatican II Declaration on Religious Freedom, Dignitatis Humanae says: "This Vatican Council declares that the human person has a right to religious freedom. This freedom means that all men are to be immune from coercion on the part of individuals or of social groups and of any human power, in such wise that no one is to be forced to act in a manner contrary to his own beliefs, whether privately or publicly, whether alone or in association with others, within due limits."

Now, any reasonable person would say that the not-particularly-blessed Pius IX and Dignitatis Humanae are diametrically opposed.
