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 XIIIAs Our Predecessors have many times repeated, let no man think that he may for any reason whatsoever join the Masonic sect, if he values his Catholic name and his eternal salvation as he ought to value them. Let no one be deceived by a pretense of honesty. It may seem to some that Freemasons demand nothing that is openly contrary to religion and morality; but, as the whole principle and object of the sect lies in what is vicious and criminal, to join with these men or in any way to help them cannot be lawful
Pope Leo XIIIThey knew only too well the intimate bond which unites faith with worship, 'the law of belief with the law of prayer,' and so, under the pretext of restoring it to its primitive form, they corrupted the order of the liturgy in many respects to adapt it to the errors of the Innovators.
Pope Leo XIIIThoughtful men, with hearts craving the truth, have come to seek in the Catholic Church the road which leads with surety to eternal life. They have understood that they could not cleave to Jesus Christ as the Head of the Church if they did not belong to the Body of Jesus Christ which is the Church. Nor could they ever hope to possess in all its purity the faith of Jesus Christ if they were to reject its legitimate teaching authority entrusted to Peter and his successors.
Pope Leo XIIINo one is so rich that he does not need another's help; no one so poor as not to be useful in some way to his fellow man; and the disposition to ask assistance from others with confidence and to grant it with kindness is part of our very nature.
Pope Leo XIIIThe sacred rites, although not instituted specifically for proving the truth of the dogmas of the Catholic Faith incontrovertibly, are effectively the living voice of Catholic Truth, the oft-sounded expression of it. For that very reason the true Church of Christ, even as she shows great zeal to guard inviolate those forms of divine worship - since they are hallowed and are not to be changed - sometimes grants or permits something novel in the performance of them in certain instances. This she does especially when they are in conformity with their venerable antiquity.
