Pope Leo XIII quotes:

Hence from all we have hitherto said, it is clear beloved Catholics that we cannot approve the opinions which some [Protestants, Jews, and other heretics] comprise under the head of Americanism [freedom].

There is in the Sacred Heart the symbol and express image of the infinite love of Jesus Christ which moves us to love in return.

The empire of Christ the King includes not only Catholic nations, not only baptized persons who, though of right belonging to the Church, have been led astray by error, or have been cut off from her by schism, but also all those who are outside the Christian faith: so that truly the whole of mankind is subject to the power of Jesus Christ.

You are not to be looked upon as holding the true Catholic faith if you do not teach that the faith of Rome is to be held

The Rosary is the most excellent form of prayer and the most efficacious means of attaining eternal life. It is the remedy for all our evils, the root of all our blessings. There is no more excellent way of praying.

Moreover, Christians are born for combat, whereof the greater the vehemence, the more assured, God willing, the triumph: 'Have confidence; I have overcome the world'

Inadequacy of his own strength, learned from experience, impels and urges a man to enlist the help of others.

Inequality of rights and power proceeds from the very Author of nature ...

For what concerns diversity of rites in the sacred liturgy, the Apostolic See has always made its position clear: not only it does not condemn diversity, but it eagerly and willingly grants to each nation the right to keep and preserve the legitimate customs and traditions of its forbears.

Inasmuch as the domestic household is antecedent, as well as in idea as in fact, the family must necessarily have rights and duties which are prior than those of the Community and founded more immediately in nature.

Once the demands of necessity and propriety have been met, the rest that one owns belongs to the poor.

Our own belief is that the renovation of the world will be brought about only by the Holy Eucharist.

Books of apostates, heretics, schismatics, and all other writers defending heresy or schism or in any attacking the foundations of religion, are altogether prohibited.

Divorce is born of perverted morals and leads to vicious habits

But the supreme teacher in the Church is the Roman Pontiff. Union of minds, therefore, requires, together with a perfect accord in the one faith, complete submission and obedience of will to the Church and to the Roman Pontiff, as to God Himself.

Catholics are born for combat.

Divorce is born of perverted morals and leads to vicious habits.

Heart of Jesus, burning with love for us, inflame our hearts with love of Thee.

The Eucharist is source and pledge of blessedness and glory, not for the soul alone, but for the body also.... In the frail and perishable body that divine Host, which is the immortal body of Christ, implants a principle of resurrection, a seed of immortality, which one day must germinate

Not only, in strict truth, was marriage instituted for the propagation of the human race, but also that the lives of husbands and wives might be made better and happier. This comes about in many ways: by their lightening each other's burdens through mutual help; by constant and faithful love; by having all their possessions in common; and by the heavenly grace which flows from the sacrament.

People differ in capacity, skill, health, strength; and unequal fortune is a necessary result of unequal condition. Such inequality is far from being disadvantageous either to individuals or to the community.

The 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.

God is not only true, but Truth itself.

All Catholics must make themselves felt as active elements in daily political life in the countries where they live. They must penetrate, wherever possible, in the administration of civil affairs; must constantly exert the utmost vigilance and energy to prevent the usages of liberty from going beyond the limits fixed by God's law. All Catholics should do all in their power to cause the constitutions of states and legislation to be modeled on the principles of the true Church.

As 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

Every man has by nature the right to possess property as his own.

Every 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.

Everyone 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.

For when men know they are working on what belongs to them, they work with far greater eagerness and diligence. Nay, in a word, they learn to love the land cultivated by their own hands, whence they look not only for food but for some measure of abundance for themselves and their dependents. All can see how much this willing eagerness contributes to an abundance of produce and the wealth of a nation.

If unbridled licence of speech and writing be granted to all, nothing will remain sacred and inviolate; even the highest and truest mandates of nature, justly held to be the common and noblest heritage of the human race, will not be spared. Thus, truth being gradually obscured by darkness, pernicious and manifold error, as too often happens, will easily prevail.

It is an in, a grave evil and a disturbance of the right order, for a larger and higher organisation, to arrogate to itself functions which can be performed efficiently by smaller and lower bodies.

It is clear that the main tenet of socialism, community of goods, must be utterly rejected, since it only injures those whom it would seem meant to benefit, is directly contrary to the natural rights of mankind, and would introduce confusion and disorder into the commonweal. The first and most fundamental principle, therefore, if one would undertake to alleviate the condition of the masses, must be the inviolability of private property.

It is not the part of prudence to neglect that which antiquity in its long experience has approved and which is also taught by apostolic authority.

It is quite unlawful to demand, defend, or to grant unconditional freedom of thought, or speech, of writing or worship, as if these were so many rights given by nature to man.

It is shameful and inhuman to treat men like chattels to make money by, or to regard them merely as so much muscle or physical power.

It must be assumed and established as a principle, that the right of private property must be regarded as sacred. Wherefore, the law ought to favor this right and, so far as it can, see that the largest possible number among the masses of the population prefer to own property.... But if the productive activity of the multitude can be stimulated by the hope of acquiring some property... , it will gradually come to pass that, with the difference between extreme wealth and extreme penury removed, one class will become the neighbor to the other.

No human law can abolish the natural and original right of marriage, nor in any way limit the chief and principal purpose of marriage ordained by God's authority from the beginning: â??Increase and multiply.

Not only, in strict truth, was marriage instituted for the propagation of the human race, but also that the lives of husbands and wives might be made better and happier.

Nothing emboldens the wicked so greatly as the lack of courage on the part of the good.

Nothing is more important than to war on war.

O Virgin most holy, none abounds in the knowledge of God except through thee; none, O Mother of God, obtains salvation except through thee, none receives a gift from the throne of mercy except through thee.

Our Lord came to the aid of each great tribulation with a special devotion. The present and future tribulations of the Church and of nations are greater than at any other period, and this persecution is more dangerous than those of previous times. Hence, the devotion which God sends to the succor of His Church and of the nations at the present time is the devotion to the Most Holy Eucharist. It is the highest of all devotions.

Peace is built on the foundation of justice.

Remember and understand well that where Peter is, there is the Church; that those who refuse to associate in communion with the Chair of Peter belong to Antichrist, not to Christ. He who would separate himself from the Roman Pontiff has no further bond with Christ.

The Church of Christ, therefore, is one and the same forever.

The death sentence is a necessary and efficacious means for the Church to attain its end when rebels act against it and disturbers of the ecclesiastical unity, especially obstinate heretics and heresiarchs, cannot be restrained by any other penalty from continuing to derange the ecclesiastical order and impelling others to all sorts of crime ... When the perversity of one or several is calculated to bring about the ruin of many of its children it is bound effectively to remove it, in such wise that if there be no other remedy for saving its people it can and must put these wicked men to death.

The devotion which God sends to the succor of His Church and of the nations at the present time is the devotion to the Most Holy Eucharist. It is the highest of all devotions.

The equal toleration of all religions...is the same as atheism.

The fact that God gave the whole human race the earth to use and enjoy cannot indeed in any manner serve as an objection against private possessions.

The family was ordained of God that children might be trained up for himself; it was before the church, or rather the first form of the church on earth.

The 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.

The present age handed over the workers, each alone and defenseless, to the unbridled greed of competitors... so that a very few and exceedingly rich men have laid a yoke of almost slavery on the unnumbered masses of non-owning workers.

The Rosary offers an easy way to present the chief mysteries of the Christian religion and to impress then upon the mind.

The 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.

The twentieth century must be a century of the Blessed Sacrament if it means to be a century of resurrection and of life

There are three influences which appear to Us to have the chief place in effecting this downgrade movement of society. These are-first, the distaste for a simple and laborious life; secondly, repugnance to suffering of any kind; thirdly, the forgetfulness of the future life.

Therefore those governing the State ought primarily to devote themselves to the service of individual groups and of the whole commonwealth, and through the entire scheme of laws and institutions to cause both public and individual well-being to develop spontaneously out of the very structure and administration of the state.

These most crafty enemies [the devils] have filled and inebriated with gall and bitterness the Church, the spouse of the Immaculate Lamb, and have laid impious hands on Her most sacred possessions. In the Holy Place itself, where has been set up the See of the most holy Peter and the Chair of Truth for the light of the world, they have raised the throne of their abominable impiety, with the iniquitous design that when the Pastor has been struck, the sheep may be scattered.

They 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.

Thoughtful 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.

To refuse any bond of union between man and civil society, on the one hand, and God the Creator and consequently the supreme Law-giver, on the other, is plainly repugnant to the nature, not only of man, but of all created things; for, of necessity, all effects must in some proper way be connected with their cause; and it belongs to the perfection of every nature to contain itself within that sphere and grade which the order of nature has assigned to it, namely, that the lower should be subject and obedient to the higher.

To suffer and to endure is the lot of humanity.

To the shepherds alone was given all power to teach, to judge, to direct; on the faithful was imposed the duty of following their teaching, of submitting with docility to their judgment, and of allowing themselves to be governed, corrected, and guided by them in the way of salvation. Thus, it is an absolute necessity for the simple faithful to submit in mind and heart to their own pastors, and for the latter to submit with them to the Head and Supreme Pastor.

To this must be added that the hiring of labor and the conduct of trade are concentrated in the hands of comparatively few; so that a small number of very rich men have been able to lay upon the teeming masses of the laboring poor a yoke little better than that of slavery itself.

Wages ought not to be insufficient to support a frugal and well-behaved wage-earner.

We are convinced that the Rosary, if devotely used is bound to benefit not only the individual but society at large.

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....

We have seen that this great labor question cannot be solved save by assuming as a principle that private ownership must be held sacred and inviolable. The law, therefore, should favor ownership, and its policy should be to induce as many as possible of the people to become owners.

We hold upon this earth the place of God Almighty.

Whoso 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.

With reason, then, the common opinion of mankind, little affected by the few dissentients who have contended for the opposite view, has found in the careful study of nature, and in the laws of nature, the foundations of the division of property, and the practice of all ages has consecrated the principle of private ownership, as being pre-eminently in conformity with human nature, and as conducing in the most unmistakable manner to the peace and tranquility of human existence.

No 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.

It is neither just nor human so to grind men down with excessive labour as to stupefy their minds and wear out their bodies.
