[O]nce ascribed to human reason the only authority to decide what is true and what is good, the real distinction between good and evil is destroyed; honor and dishonor differ not in their nature, but in the opinion and judgment of each one; pleasure is the measure of what is lawful; and, given a code of morality which can have little or no power to restrain or quiet the unruly propensities of man, a way is naturally opened to universal corruption. With reference also to public affairs: authority is severed from the true and natural principle whence it derives all its efficacy for the common good; and the law determining what it is right to do and avoid doing is at the mercy of a majority. Now, this is simply a road leading straight to tyranny....[W]hen anything is commanded which is plainly at variance with the will of God, there is a wide departure from this divinely constituted order, and at the same time a direct conflict with divine authority; therefore, it is right not to obey.
By the patrons of liberalism, however, who make the State absolute and omnipotent, and proclaim that man should live altogether independently of God, the liberty of which We speak, which goes hand in hand with virtue and religion, is not admitted; and whatever is done for its preservation is accounted an injury and an offense against the State. Indeed, if what they say were really true, there would be no tyranny, no matter how monstrous, which we should not be bound to endure and submit to.

We have but too much evidence of the value and result of a morality divorced from divine faith. How is it that, in spite of all the zeal for the welfare of the masses, nations are in such straits and even distress, and that the evil is daily on the increase? We are told that society is quite able to help itself; that it can flourish without the assistance of Christianity, and attain its end by its own unaided efforts. Public administrators prefer a purely secular system of government. All traces of the religion of our forefathers are daily disappearing from political life and administration. What blindness! Once the idea of the authority of God as the Judge of right and wrong is forgotten, law must necessarily lose its primary authority and justice must perish: and these are the two most powerful and most necessary bonds of society. Similarly, once the hope and expectation of eternal happiness is taken away, temporal goods will be greedily sought after. Every man will strive to secure the largest share for himself. Hence arise envy, jealousy, hatred. The consequences are conspiracy, anarchy, nihilism. There is neither peace abroad nor security at home. Public life is stained with crime.
So great is this struggle of the passions and so serious the dangers involved, that we must either anticipate ultimate ruin or seek for an efficient remedy. It is of course both right and necessary to punish malefactors, to educate the masses, and by legislation to prevent crime in every possible way: but all this is by no means sufficient. The salvation of the nations must be looked for higher.
