Encyclical in the context of "Ad Caeli Reginam"

Deiparae Virginis Mariae (Latin for "Virgin Mary Mother of God"), is an encyclical of Pope Pius XII released on May 1, 1946 addressed to all Catholic bishops on the possibility of defining the Assumption of the Blessed Virgin Mary as a dogma of faith.

The encyclical states that for a long time numerous petitions have been received from cardinals, patriarchs, archbishops, bishops, priests, religious of both sexes, associations, universities and innumerable private persons, all begging that the bodily Assumption into heaven of the Blessed Virgin should be defined and proclaimed as a dogma of faith. This was also fervently requested by almost two hundred fathers in the Vatican Council (1869–1870).

Pope Pius XI (Italian: Pio XI; born Ambrogio Damiano Achille Ratti, Italian: [amˈbrɔːdʒo daˈmjaːno aˈkille ˈratti]; 31 May 1857 – 10 February 1939) was head of the Catholic Church from 6 February 1922 until his death in February 1939. He was also the first sovereign of the Vatican City upon its creation on 11 February 1929.

Pius XI issued numerous encyclicals, including Quadragesimo anno on the 40th anniversary of Pope Leo XIII's groundbreaking social encyclical Rerum novarum, highlighting the capitalistic greed of international finance, the dangers of atheistic socialism/communism, and social justice issues, and Quas primas, establishing the feast of Christ the King in response to anti-clericalism. The encyclical Studiorum ducem, promulgated 29 June 1923, was written on the occasion of the 6th centenary of the canonization of Thomas Aquinas, whose thought is acclaimed as central to Catholic philosophy and theology. The encyclical also singles out the Pontifical University of Saint Thomas Aquinas, Angelicum as the preeminent institution for the teaching of Aquinas: "ante omnia Pontificium Collegium Angelicum, ubi Thomam tamquam domi suae habitare dixeris" (before all others the Pontifical Angelicum College, where Thomas can be said to dwell). The encyclical Casti connubii promulgated on 31 December 1930 prohibited Catholics from using contraception.

Catholic social teaching (CST) is an area of Catholic doctrine which is concerned with human dignity and the common good in society. It addresses oppression, the role of the state, subsidiarity, social organization, social justice, and wealth distribution. CST's foundations are considered to have been laid by Pope Leo XIII's 1891 encyclical, Rerum novarum, of which interpretations gave rise to distributism (formulated by G. K. Chesterton), Catholic socialism (proposed by Andrew Collier) and Catholic communism, among others. Its roots can be traced to Catholic theologians such as Thomas Aquinas and Augustine of Hippo. CST is also derived from the Bible and cultures of the ancient Near East.

According to Pope John Paul II, the foundation of social justice "rests on the threefold cornerstones of human dignity, solidarity and subsidiarity". According to Pope Benedict XVI, its purpose "is simply to help purify reason and to contribute, here and now, to the acknowledgment and attainment of what is just ... [The church] has to play her part through rational argument and she has to reawaken the spiritual energy without which justice ... cannot prevail and prosper." Pope Francis, according to Cardinal Walter Kasper, made mercy "the key word of his pontificate... [while] Scholastic theology has neglected this topic and turned it into a mere subordinate theme of justice."

Laudato si' (Praise Be to You) is the second encyclical of Pope Francis, subtitled "on care for our common home". In it, the Pope criticizes consumerism and irresponsible economic development, laments environmental degradation and global warming, and calls all people of the world to take "swift and unified global action". The encyclical, dated 24 May 2015, was officially published at noon on 18 June 2015, accompanied by a news conference. The Vatican released the document in Italian, German, English, Spanish, French, Polish, Portuguese and Arabic, alongside the original Latin.

The encyclical is the second published by Pope Francis, after Lumen fidei (The Light of Faith), which was released in 2013. Since Lumen fidei was largely the work of Francis's predecessor Benedict XVI, Laudato si' is generally viewed as the first encyclical that is entirely the work of Francis.

A crusade bull or crusading bull (Latin: bulla cruciata) was a papal bull that granted privileges, including indulgences, to those who took part in the Crusades against infidels. A bull is an official document issued by a pope and sealed with a leaden bulla. All crusade bulls were written in Latin. Those launching a new general crusade were encyclicals addressed to all the archbishops of the Latin Church.

Bulls were not the only means by which popes organized crusades. Many types of papal letters without the bulla attached were issued to arrange, guide and direct crusading efforts. The bulls issued for the Reconquista ('reconquest') in the Iberian Peninsula evolved into something distinct. By the modern period, the "bull of the crusade" (Spanish: bula de la cruzada, Portuguese: bula da cruzada) was used by Spanish and Portuguese monarchs as a means of raising money through donations for various projects, not necessarily military. This system was finally abolished in 1966.

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.

The term modernism—generally used by its critics rather than by adherents of positions associated with it—came to prominence in Pope Pius X's 1907 encyclical Pascendi Dominici gregis, where he condemned modernism as "the synthesis of all heresies".

Pope Pius X (Italian: Pio X; born Giuseppe Melchiorre Sarto; 2 June 1835 – 20 August 1914) was head of the Catholic Church from 4 August 1903 until his death in August 1914. Pius X is known for vigorously opposing modernist interpretations of Catholic doctrine, and for promoting liturgical reforms and Thomist scholastic theology. He initiated the preparation of the 1917 Code of Canon Law, the first comprehensive and systemic work of its kind, which was ultimately promulgated by his successor. He is venerated as a saint in the Catholic Church.

Pius X was devoted to the Blessed Virgin Mary under the title of Our Lady of Confidence; while his papal encyclical Ad diem illum took on a sense of renewal that was reflected in the motto of his pontificate. He advanced the Liturgical Movement by formulating the principle of participatio actuosa (active participation of the faithful) in his motu proprio, Tra le sollecitudini (1903). He encouraged the frequent reception of Holy Communion, and he lowered the age for First Communion, which would become a lasting innovation of his papacy.
