The best parent and guardian of liberty amongst men is truth.
Encyclical: Immortale Dei (1885)
Whoever has received from the divine bounty a large share of temporal blessings, whether they be external and material, or gifts of the mind, has received them for the purpose of using them for the perfecting of his own nature, and, at the same time, that he may employ them, as the steward of God's providence, for the benefit of others.
Rerum novarum (1891)
Base trade in human beings carried on in the most barbarous fashion, those who wield power, those who sway empires, those who desire that the rights of nature and humanity be respected, and those who desire the progress of religion, to unite everywhere towards the abolition of this most shameful and most criminal traffic.
To hold, therefore, that there is no difference in matters of religion between forms that are unlike each other, and even contrary to each other, most clearly leads in the end to the rejection of all religion in both theory and practice.
Encyclical: Immortale Dei 31 (1885)
