  • “Reveal to the faithful the wolves which are demolishing the Lord’s vineyard.”
    —Pope Clement XIII, Encyclical Christianae Reipublicae, 1766
  • “We must remember that if all the manifestly good men were on one side and all the manifestly bad men on the other, there would be no danger of anyone, least of all the elect, being deceived by lying wonders.  It is the good men, good once, we must hope good still, who are to do the work of Anti-Christ and so sadly to crucify the Lord afresh…. Bear in mind this feature of the last days, that this deceitfulness arises from good men being on the wrong side.”
    —Fr. Frederick Faber, Sermon for Pentecost Sunday, 1861; qtd. in Fr. Denis Fahey, The Mystical Body of Christ in the Modern World (text here)
  • “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.”
    —Pope Leo XIII, Encyclical Custodi di Quella Fede, n. 15, 1892
  • “It is impious to say, ‘I respect every religion.’ This is as much as to say: I respect the devil as much as God, vice as much as virtue, falsehood as much as truth, dishonesty as much as honesty, Hell as much as Heaven.”
    Fr. Michael MüllerThe Church and Her Enemies (source here)
  • “The Papacy will be attacked by all the powers of hell. In consequence the Church will suffer great trials and afflictions in securing a successor upon the throne of Peter…. It is a matter of history that the most disastrous periods for the Church were times when the Papal throne was vacant, or when anti-popes contended with the legitimate head of the Church. Thus also shall it be in those evil days to come.”
    —Fr. E. Sylvester BerryThe Apocalypse of St. John (1921), pp. 121, 124
  • “Our Apostolic Mandate requires from Us that We watch over the purity of the Faith and the integrity of Catholic discipline. It requires from Us that We protect the faithful from evil and error; especially so when evil and error are presented in dynamic language which, concealing vague notions and ambiguous expressions with emotional and high-sounding words, is likely to set ablaze the hearts of men in pursuit of ideals which, whilst attractive, are nonetheless nefarious.”
    Pope St. Pius X, Apostolic Letter Notre Charge Apostolique, 1910
  • “[According to the doctrine of the Modernists] it is necessary that the primitive [religious] formulas be accepted and sanctioned by the heart; and similarly the subsequent work from which are brought forth the secondary formulas must proceed under the guidance of the heart. Hence it comes that these formulas, in order to be living, should be, and should remain, adapted to the faith and to him who believes. Wherefore, if for any reason this adaptation should cease to exist, they lose their first meaning and accordingly need to be changed. In view of the fact that the character and lot of dogmatic formulas are so unstable, it is no wonder that Modernists should regard them so lightly and in such open disrespect, and have no consideration or praise for anything but the religious sense and for the religious life. In this way, with consummate audacity, they criticize the Church, as having strayed from the true path by failing to distinguish between the religious and moral sense of formulas and their surface meaning, and by clinging vainly and tenaciously to meaningless formulas, while religion itself is allowed to go to ruin.”
    Pope St. Pius X, Encyclical Pascendi Dominici Gregis, n. 13, 1907
  • “Therefore the whole and entire Catholic doctrine is to be presented and explained: by no means is it permitted to pass over in silence or to veil in ambiguous terms the Catholic truth regarding the nature and way of justification, the constitution of the Church, the primacy of jurisdiction of the Roman Pontiff, and the only true union by the return of the dissidents to the one true Church of Christ.”
    —Pope Pius XII, Instruction On the Ecumenical Movement, n. II, 1949
  • “Even on the plea of promoting unity it is not allowed to dissemble one single dogma; for, as the Patriarch of Alexandria warns us, ‘although the desire of peace is a noble and excellent thing, yet we must not for its sake neglect the virtue of loyalty in Christ.’ Consequently, the much desired return of erring sons to true and genuine unity in Christ will not be furthered by exclusive concentration on those doctrines which all, or most, communities glorying in the Christian name accept in common. The only successful method will be that which bases harmony and agreement among Christ’s faithful ones upon all the truths, and the whole of the truths, which God has revealed.”
    —Pope Pius XII, Encyclical Orientalis Ecclesiae, n. 16, 1944
  • “Now you know well that the most deadly foes of the Catholic religion have always waged a fierce war, but without success, against this Chair [of St. Peter]; they are by no means ignorant of the fact that religion itself can never totter and fall while this Chair remains intact, the Chair which rests on the rock which the proud gates of hell cannot overthrow and in which there is the whole and perfect solidity of the Christian religion.”
    —Pope Pius IXEncyclical Inter Multiplices, n. 7, 1853
  • “…[I]t is not allowable for anyone to produce another faith, that is, to write or to compose or to consider or to teach others; those who dare to compose another faith, or to support or to teach or to hand on another creed to those who wish to turn to knowledge of the truth, whether from Hellenism or Judaism or indeed from any heresy whatsoever, or to introduce novelty of speech, that is, invention of terms, so as to overturn what has now been defined by us, such persons, if they are bishops or clerics, are deprived of their episcopacy or clerical rank, and if they are monks or layfolk they are excommunicated.”
    —Pope St. Leo II, Third Council of Constantinople, 681
  • “The declared enemies of God and His Church, heretics and schismatics, must be criticized as much as possible, as long as truth is not denied. It is a work of charity to shout: ‘Here is the wolf!’ when it enters the flock or anywhere else.”
    St. Francis de SalesIntroduction to the Devout Life, Part III, Chapter 29
  • “We ought to remember that Catholics are, far more than the Jews were, the chosen people of God….”
    —Fr. Richard F. Clarke, “The Ministry of Jesus: Short Meditations on the Public Life of Our Lord”, in Beautiful Pearls of Catholic Truth, p. 542)
  • “Trusting in God and relying on His ever present help, [St. Benedict] went south and arrived at a fort ‘called Cassino situated on the side of a high mountain…; on this stood an old temple where Apollo was worshipped by the foolish country people, according to the custom of the ancient heathens. Around it likewise grew groves, in which even till that time the mad multitude of infidels used to offer their idolatrous sacrifices. The man of God coming to that place broke the idol, overthrew the altar, burned the groves, and of the temple of Apollo made a chapel of St. Martin. Where the profane altar had stood he built a chapel of St. John; and by continual preaching he converted many of the people thereabout’.”
    —Pope Pius XII, Encyclical Fulgens Radiatur, n. 11, 1947; showing the anti-ecumenical nature of Roman Catholicism and that the true path to the conversion and salvation of people is not to respect their false religions but to lead them out of them into the True Faith
  • “As we said earlier, I repeat once more: If anyone preaches to you a gospel contrary to what you have received, let him be accursed. …The heretic, even though he has not been condemned formally by any individual, in reality brings anathema on himself, having cut himself off from the way of truth by his heresy. What reply can such people make to the Apostle when he writes: As for someone who is factious, after admonishing him once or twice, have nothing more to do with him, knowing that such a person is perverted and sinful; he is self-condemned. It was in the spirit of this text that Cyril of holy memory, in the books which he wrote against Theodore, declared as follows: ‘Whether or not they are alive, we ought to keep clear of those who are in the grip of such dreadful errors. It is necessary always to avoid what is harmful, and not to be worried about public opinion but rather to consider what is pleasing to God’.”
    —Pope Vigilius, Second Council of Constantinople, 553
  • “…diabolical error, when it has artfully colored its lies, easily clothes itself in the likeness of truth while very brief additions or changes corrupt the meaning of expressions; and confession, which usually works salvation, sometimes, with a slight change, inches toward death.”
    —Pope Clement XIII, Encyclical In Dominico Agro, n. 2, 1761
  • “For the mystery of iniquity already worketh; only that he who now holdeth, do hold, until he be taken out of the way. And then that wicked one shall be revealed whom the Lord Jesus shall kill with the spirit of his mouth; and shall destroy with the brightness of his coming, him, Whose coming is according to the working of Satan, in all power, and signs, and lying wonders, And in all seduction of iniquity to them that perish; because they receive not the love of the truth, that they might be saved. Therefore God shall send them the operation of error, to believe lying: That all may be judged who have not believed the truth, but have consented to iniquity.
    St. Paul the Apostle (2 Thess 2:7-11)
  • “Compromise with those not of the Faith is at all times the deadliest of errors. Here precisely is the danger of religious indifferentism. Here is the danger of socialism. Here is the danger of mixed marriages. Here is the danger of seeking to keep at all costs the golden opinion of the world and fearing its contempt. Here is the danger of education in non-Catholic schools, no matter how innocent they may seem to be.”
    Fr. Joseph HussleinThe Catholic’s Work in the World (1917), pp. 93-94
  • “The propagators and abettors of heresy, as well as its authors, have at all times been called heretics. As the Church has always considered heresy a very grave evil, so has she always called its adherents bad and pervert. Run over the list of ecclesiastical writers — you will then see how the Apostles treated the first heretics, how the Fathers and modern controversialists and the Church herself in her official language has pursued them. There is then no sin against charity in calling evil evil; its authors abettors and its disciples bad; all its acts, words, and writings iniquitous, wicked, malicious. In short, the wolf has always been called the wolf; and in so calling it, no one ever has believed that wrong was done to the flock and the shepherd. If the propagation of good and the necessity of combating evil require the employment of terms somewhat harsh against error and its supporters, this usage is certainly not against charity. This is a corollary or consequence of the principle we have just demonstrated. We must render evil odious and detestable. We cannot attain this result without pointing out the dangers of evil, without showing how and why it is odious, detestable and contemptible. Christian oratory of all ages has ever employed against impiety the most vigorous and emphatic rhetoric in the arsenal of human speech. In the writings of the great athletes of Christianity, the usage of irony, imprecation, execration and of the most crushing epithets is continual. Hence the only law is the opportunity and the truth.”
    –Fr. Felix Sarda y Salvany, Liberalism is a Sin, Chapter 20, 1886
  • “Let no Christian therefore, whether philosopher or theologian, embrace eagerly and lightly whatever novelty happens to be thought up from day to day, but rather let him weigh it with painstaking care and a balanced judgment, lest he lose or corrupt the truth he already has, with grave danger and damage to his faith.”
    —Pope Pius XII, Encyclical Humani Generis, n. 30, 1950
  • “These moderns, forever prattling about culture and civilization, are undermining the Church’s doctrine, laws, and practices. They are not concerned very much about culture and civilization. By using such high-sounding words they think they can conceal the wickedness of their schemes. All of you know their purpose, subterfuges, and methods. On Our part We have denounced and condemned their scheming. They are proposing a universal apostasy even worse than the one that threatened the age of Charles [Borromeo]. It is worse, We say, because it stealthily creeps into the very veins of the Church, hides there, and cunningly pushes erroneous principles to their ultimate conclusions.”
    —Pope St. Pius X, Encyclical Editae Saepe, nn. 17-18, 1910
  • “The Church will be punished because the majority of her members, high and low, will become so perverted. The Church will sink deeper and deeper until she will at last seem to be extinguished, and the succession of Peter and the other Apostles to have expired. But, after this, she will be victoriously exalted in the sight of all doubters.”
    St. Nicholas of Flue, in Catholic Prophecy, edited by Yves Dupont, p. 30
  • “In our time more than ever before, the chief strength of the wicked, lies in the cowardice and weakness of good men… All the strength of Satan’s reign is due to the easy-going weakness of Catholics. Oh! if I might ask the Divine Redeemer, as the prophet Zachary did in spirit: What are those wounds in the midst of Thy hands? The answer would not be doubtful: With these was I wounded in the house of them that loved Me. I was wounded by My friends, who did nothing to defend Me, and who, on every occasion, made themselves the accomplices of My adversaries. And this reproach can be levelled at the weak and timid Catholics of all countries.”
    Pope St. Pius X, Discourse at the Beatification of St. Joan of Arc, 1908 (found in Acta Apostolicae Sedis, vol. I, pp. 142-145)
  • “But their profession of fidelity to the Vicar of Christ is vain in those who, in fact, do not cease to violate the authority of their Bishops. For ‘by far the most august part of the Church consists of the Bishops, (as Our Predecessor Leo XIII of holy memory wrote in his letter of December 17, 1888, to the Archbishop), inasmuch as this part by divine right teaches and rules men; hence, whoever resists them or pertinaciously refuses obedience to them puts himself apart from the Church. . . On the other hand, to pass judgment upon or to rebuke the acts of Bishops does not at all belong to private individuals — that comes within the province only of those higher than they in authority and especially of the Sovereign Pontiff, for to him Christ entrusted the charge of feeding not only His lambs, but His sheep throughout the world. At most, it is allowed in matters of grave complaint to refer the whole case to the Roman Pontiff, and this with prudence and moderation as zeal for the common good requires, not clamorously or abusively, for in this way dissensions and hostilities are bred, or certainly increased.'”
    –Pope St. Pius X, Encyclical Tribus Circiter, n. 9, 1906
  • “The apostles and their successors are God’s vicars in governing the Church which is built on faith and the sacraments of faith. Wherefore, just as they may not institute another Church, so neither may they deliver another faith, nor institute other sacraments.”
    St. Thomas AquinasSumma Theologica, III, q. 64, art. 2, ad. 3
  • “I hear around me reformers who want to dismantle the Holy Sanctuary, destroy the universal flame of the Church, to discard all her adornments, and smite her with remorse for her historic past.”
    Cardinal Eugenio Pacelli (the future Pope Pius XII) to Count Enrico P. Galeazzi
  • “Pope Gelasius in his ninth letter (chap. 26) to the bishops of Lucania condemned the evil practice which had been introduced of women serving the priest at the celebration of Mass. Since this abuse had spread to the Greeks, Innocent IV strictly forbade it in his letter to the bishop of Tusculum: ‘Women should not dare to serve at the altar; they should be altogether refused this ministry.’ We too have forbidden this practice in the same words….”
    Pope Benedict XIV, Encyclical Allatae Sunt, 1755
  • “On December 8, 1869, the International Congress of Freemasons imposed it as a duty on all its members to do all in their power to wipe out Catholicity from the face of the earth. Cremation was proposed as a suitable means to this end, since it was calculated to gradually undermine the faith of the people in ‘the resurrection of the body and life everlasting.'”
    Fr. John LauxCatholic Morality (1934), p. 106
  • “…the liberty of thinking, and of publishing, whatsoever each one likes, without any hindrance, is not in itself an advantage over which society can wisely rejoice. On the contrary, it is the fountain-head and origin of many evils. Liberty is a power perfecting man, and hence should have truth and goodness for its object. But the character of goodness and truth cannot be changed at option. These remain ever one and the same, and are no less unchangeable than nature itself. If the mind assents to false opinions, and the will chooses and follows after what is wrong, neither can attain its native fullness, but both must fall from their native dignity into an abyss of corruption.”
    —Pope Leo XIII, Encyclical Immortale Dei, n. 32, 1885
  • “It is impossible to approve in Catholic publications a style inspired by unsound novelty which seems to deride the piety of the faithful and dwells on the introduction of a new order of Christian life, on new directions of the Church, on new aspirations of the modern soul, on a new social vocation of the clergy, on a new Christian civilization, and many other things of the same kind.”
    Pope Leo XIII, Instruction to the Sacred Congregation of Extraordinary Ecclesiastical Affairs, 1902; quoted by Pope St. Pius X in Pascendi Dominici Gregis, n. 55, 1907
  • “…the great movement of apostasy being organized in every country for the establishment of a One-World Church which shall have neither dogmas, nor hierarchy, neither discipline for the mind, nor curb for the passions, and which, under the pretext of freedom and human dignity, would bring back to the world (if such a Church could overcome) the reign of legalized cunning and force, and the oppression of the weak, and of all those who toil and suffer. […] Indeed, the true friends of the people are neither revolutionaries, nor innovators: they are traditionalists.”
    Pope St. Pius X, Apostolic Letter Notre Charge Apostolique, 1910
  • “When other Christian bodies are licensing as preachers young men who have abandoned the foundations of Christian belief, the Church would rather face the threatened defection of thousands of minds reputed brilliant or learned, than sacrifice one iota of the Truth confided to her by her Founder.”
    America: A Catholic Review of the Week, vol. 1, n. 15 (July 24, 1909), p. 410
  • “The Son of Man, when He cometh, shall He find, think you, faith on earth?”
    Blessed Lord Jesus Christ (Lk 18:8)
