We have said that the State must not absorb the individual or the family; both should be allowed free and untrammelled action so far as is consistent with the common good and the interest of others. Rulers should, nevertheless, anxiously safeguard the community and all its members; the community, because the conservation thereof is so emphatically the business of the supreme power, that the safety of the commonwealth is not only the first law, but it is a government's whole reason of existence.
Pope Leo XIIIThe first law of history is to dread uttering a falsehood; the next is not to fear stating the truth; lastly, the historian's writings should be open to no suspicion of partiality or animosity.
Pope Leo XIIIWhoso turns his attention to the bitter strifes of these days and seeks a reason for the troubles that vex public and private life must come to the conclusion that a fruitful cause of the evils which now afflict, as well as of those which threaten us, lies in this: that false conclusions concerning divine and human things, which originated in the schools of philosophy, have crept into all the orders of the state, and have been accepted by the common consent of the masses.
Pope Leo XIIIEvery man has by nature the right to possess property as his own. This is one of the chief points of distinction between man and the animal creation.
Pope Leo XIIIThe liberty of thinking and publishing whatsoever each one likes, without any hindrances, is not in itself an advantage over which society can wisely rejoice. On the contrary, it is the fountainhead and origin of many evils.
Pope Leo XIIIEveryone should avoid familiarity or friendship with anyone suspected of belonging to masonry or to affiliated groups. Know them by their fruits and avoid them. Every familiarity should be avoided, not only with those impious libertines who openly promote the character of the sect, but also with those who hide under the mask of universal tolerance, respect for all religions, and the craving to reconcile the maxims of the Gospel with those of the revolution. These men seek to reconcile Christ and Belial, the Church of God and the state without God.
Pope Leo XIII
