Supreme Sacred Congregation of the Holy Office

Condemnation of 12 Propositions pertaining to the Philosophy of Action
December 1, 1924
Students of apologetics will be interested in the following reply of the Holy Office to a series of questions proposed regarding the doctrinal correctness of certain propositions held by some modern teachers in philosophy and theology. The twelve propositions here censured as untenable on Catholic scholastic grounds have in substance been condemned as contrary to right faith and morals by the doctrinal authority of the [First] Vatican Council, but are here separately emphasized to meet definite errors.

Allocution of Pope Pius XII
Magnificate Dominum (1954)
Address of His Holiness Pope Pius XII to Cardinals, Archbishops, and Bishops on the Catholic Church and her Powers of Sanctifying and Ruling, Nov. 2, 1954
“Magnify the Lord with me; together let us extoll His name” (Ps. 33,4), for by a new favor from Heaven has Our desire been fulfilled, and at the same time We rejoice at the sight of you, beloved sons and venerable brothers, gathered before Us in such large numbers. And the consideration of the new liturgical feast of Mary, Mother of God and Queen of Heaven and Earth, which We just recently solemnly proclaimed, swells Our holy joy; for it is only fitting for her children to rejoice when they see an increase of honor accorded their mother.… READ MORE

Super Soliditate (1786)
Bull of Pope Pius VI, issued on November 28, 1786, condemning the errors of Johann Valentin Eybel (1741-1805), also known as “Febronianism”
That the Church was established by Jesus Christ on the solid foundation of the rock (cf. Mt 16:18); that Peter, above all the others, was chosen by the singular favor of Jesus Christ, so that, having the power of his Vicar on earth, he became the Prince of the Apostolic College and received, in consequence, for himself and for his successors to the end of time, the charge and the supreme authority to feed the flock (cf.… READ MORE
Address of Pope Saint Pius X

Con Vera Soddisfazione (1909)
From Pope Pius X in Audience on May 10, 1909, to Youths attached to Catholic Universities, assembled after the second Convention in Rome
It is with genuine joy that I welcome the sentiments and expressions of devotion and reverence toward this Apostolic See which you have declared to me in your name and that of your companions. And these [sentiments] are all the more dear to me because they are expressed by young people who, dedicated to studying in order to attain the goal of true knowledge, declare themselves to be followers of Catholic doctrine and recognize the necessity of uniting in a holy union these two daughters of the same Father, reason and faith, by which we all live: these two suns, which shine in the sky of our souls; these two forces, which constitute the beginning and the end of our grandeur; these two wings which rise up to the knowledge of all truth: in a single word, reason, which is the eye of man who sees, aided by the eye of God, which is faith.… READ MORE

Accogliamo Colla Più Viva Compiacenza (1907)
Allocution which Pope Pius X delivered to newly-created Cardinals on Apr. 17, 1907, against Religious Neo-Reformism
We welcome with the most vivid delight the expressions of devotion and filial love for us and for this Apostolic See, which you have shown to us in your name and in the name of your most beloved brothers for the honor of the purple to which you were called [footnote: Card. Aristide Cavallari, Patriarch of Venice]. In accepting your gratitude, nevertheless, we have also to say that the same preeminent virtues by which you are adorned, the works of zeal which you have performed, and the other distinguished services which in different fields you have rendered to the Church, have made you worthy to be included in the register of Our Sacred Senate. … READ MORE
Allocution of Pope Saint Pius X

Festivitas Dominicae Passionis (1907)
Allocution of His Holiness Pope Pius X
given to Cardinals gathered in Consistory on Apr. 15, 1907,
on the mournful condition of the Church in France
Venerable Brothers,
The liturgical remembrance of the Lord’s Passion, to which we lately attended amid transports of spiritual joys, warned us, with a repeated lesson as it were, that the Church, the Bride of Christ, in pursuing the work of mankind’s regeneration and in the struggle that she has on that account against the world of darkness, is summoned not to comfort on this earth, but to hardships and troubles.… READ MORE
Allocution of Pope Pius IX

Iamdudum Cernimus (1861)
Allocution of His Holiness Pope Pius IX to Cardinals gathered in private Consistory on March 18, 1861
from which the 1864 Syllabus of Errors draws condemned propositions 37, 61, and 80
1. Now after a long time We see, Venerable Brothers, by what a truly lamentable conflict civil society is being continually disturbed, especially in this our most unfortunate age, on account of principles alternatively contending between truth and error, between virtue and vice, between light and darkness. For instance, on the one hand, some uphold certain beliefs of, as they term it, “modern civilization.”… READ MORE
The Catholic Teaching on the Papacy
A Collection of Quotes from Magisterial Documents

In our day there are a lot of people who call themselves, and mean to be, traditional Roman Catholics. Yet a great many of them do not hold to the traditional Catholic understanding of the Papacy, either because they do not know it or because they unhappily accept the “Popes” after Pius XII as valid and legitimate but know that they cannot submit to them without abandoning the traditional Catholic Faith. The tragic irony in the latter case is that by denying the Catholic teaching on the Papacy, they are abandoning the Faith just as much.… READ MORE

Quamvis Inquieti (1946)
Allocution of His Holiness Pope Pius XII to the Fathers of the Society of Jesus, Delegates in General Congregation XXIX, Sep. 17, 1946
Now there is nothing that calls us more urgently and pressingly than to restore the authority of religion and Christian moral discipline with due honor and vigor. Alas, into what times we have fallen because of the negligence of those immortal goods given to us by God! Wherever one looks one sees those who are totally ignorant of the Catholic faith, even the rudiments of religion itself. We see those who see nothing impious in crimes and license, those who disregard even the most elementary norms of morality and justice.… READ MORE

September 16, 1864
A Letter of the Supreme Holy Roman and Universal Inquisition to all the English Bishops
It has been notified to the Apostolic See that some Catholics and even ecclesiastics have given their names to a Society established in London in the year 1857, ‘for promoting’ (as it is called) ‘the unity of Christendom;’ and that several articles have been published in the daily papers signed with the names of Catholics, in approval of this Society, or supposed to have been written by ecclesiastics in its favour.… READ MORE
