Dignitatis humanae is the Second Vatican Council's Declaration on Religious Freedom. In the context of the council's stated intention "to develop the doctrine of recent popes on the inviolable rights of the human person and the constitutional order of society", Dignitatis humanae spells out the church's support for the protection of religious liberty. It set the ground rules by which the church would relate to secular states.
Pope Pius IX was head of the Catholic Church from 1846 to 1878. His reign of nearly 32 years is the longest of any pope since the first century. He was notable for convoking the First Vatican Council in 1868 and for permanently losing control of the Papal States in 1870 to the Kingdom of Italy. Thereafter, he refused to leave Vatican City, declaring himself a "prisoner in the Vatican".
In politics, integralism, integrationism or integrism is an interpretation of Catholic social teaching that argues the principle that the Catholic faith should be the basis of public law and public policy within civil society, wherever the preponderance of Catholics within that society makes this possible. Integralism is anti-pluralist, seeking the Catholic faith to be dominant in civil and religious matters. Integralists uphold the 1864 definition of Pope Pius IX in Quanta cura that the religious neutrality of the civil power cannot be embraced as an ideal situation and the doctrine of Leo XIII in Immortale Dei on the religious obligations of states. In December 1965, the Second Vatican Council approved and Pope Paul VI promulgated the document Dignitatis humanae–the Council's "Declaration on Religious Freedom"–which states that it "leaves untouched traditional Catholic doctrine on the moral duty of men and societies toward the true religion and toward the one Church of Christ". However, they have simultaneously declared "that the human person has a right to religious freedom," a move that some traditionalist Catholics such as Archbishop Marcel Lefebvre, the founder of the Society of St. Pius X, have argued is at odds with previous doctrinal pronouncements.
Quanta cura was a papal encyclical issued by Pope Pius IX on 8 December 1864. In it, he decried what he considered significant errors afflicting the modern age. These he listed in an attachment called the Syllabus of Errors, which condemned secularism and religious indifferentism.
Modernism in the Catholic Church describes attempts to reconcile Catholicism with modern culture, specifically an understanding of the Bible and Sacred Tradition in light of the historical-critical method and new philosophical and political developments of the late 19th and early 20th centuries.
Pascendi Dominici gregis is a papal encyclical letter, subtitled "On the Doctrines of the Modernists", promulgated by Pope Pius X on 8 September 1907.
Mirari vos, sometimes referred to as Mirari vos arbitramur, was the fourth encyclical letter of Pope Gregory XVI and was issued in August 1832. Addressed to "All Patriarchs, Primates, Archbishops, and Bishops of the Catholic World", it is general in its audience and scope, whereas his three earlier encyclicals had been addressed to more specific audiences in the Papal States and the Kingdom of Poland.
Quibus quantisque malis was a papal allocution of Pius IX addressed to the Consistory of Cardinals on April 20, 1849, discussing the recent political atmosphere.
Singulari Nos was an encyclical issued on June 25, 1834, by Pope Gregory XVI. Essentially a follow-up to the better-known Mirari vos of 1832, Singulari Nos focused strongly on the views of French priest Felicité Robert de Lamennais, who did not see any contradiction between Catholicism and then-modern ideals of liberalism and the separation of church and State.
There are many papal pronouncements against Freemasonry; the most prominent include:
Luigi Maria Bilio, was a Cardinal of the Roman Catholic Church who, among other offices, was Secretary of the Supreme Sacred Congregation of the Holy Office.
Mariological papal documents have been a major force that has shaped Roman Catholic Mariology over the centuries. Mariology is developed by theologians on the basis not only of Scripture and Tradition but also of the sensus fidei of the faithful as a whole, "from the bishops to the last of the faithful", and papal documents have recorded those developments, defining Marian dogmas, spreading doctrines and encouraging devotions within the Catholic Church.
Romano Amerio was a Swiss-Italian theologian and a late critic of post-Conciliar evolutions in liturgy and ecclesiology. His magnum opus is Iota Unum. It is a work dedicated to the study of the ruptures in Church teaching and tradition following the Second Vatican Council.
The Decree Against Communism was a 1949 Catholic Church document issued by the Supreme Sacred Congregation of the Holy Office, and approved by Pope Pius XII, which declared Catholics who professed atheistic communist doctrine to be excommunicated as apostates from the Christian faith. It did not prohibit membership in communist parties per se, but applied to Catholic communists who 'abandoned their faith'. The decree was issued in response to pro-communist and state-sponsored Catholic associations being founded in the socialist Eastern Bloc, which prompted fears of schism. The Vatican stopped enforcing the decree after reaching compromises with the socialist states, starting with an agreement reached with the Polish People's Republic in 1950. The decree has since been abrogated, and is no longer valid.
Lamentabili sane exitu is a 1907 syllabus, prepared by the Roman Inquisition and confirmed by Pope Pius X, which condemns what it deems to be errors in the exegesis of Holy Scripture and in the history and interpretation of dogma.
The theology of Pope Pius IX championed the pontiff's role as the highest teaching authority in the Church.
Jamdudum cernimus is a declaration in the form of an allocution given by Pope Pius IX on 18 March 1861. It has been cited as a source for the last and most famous statement of the Syllabus of Errors, that of the irreconcilability between Christian civilization and modern liberal civilization.
The modern history of the papacy is shaped by the two largest dispossessions of papal property in its history, stemming from the French Revolution and its spread to Europe, including Italy.
Liberalism is a Sin is a controversial book written by Roman Catholic priest Félix Sardà y Salvany in 1884, which became a rallying point for conservative political movements such as Integrism and Carlism.
