Catholic countries in the context of "Vatican II"

The Friday of Sorrows or Passion Friday is a solemn pious remembrance of the sorrowful Blessed Virgin Mary on the Friday before Palm Sunday held in the fifth week of Lent (formerly called "Passion Week"). In the Anglican Ordinariate's Divine Worship: The Missal it is called Saint Mary in Passiontide and sometimes it is traditionally known as Our Lady in Passiontide.

In certain Catholic countries, especially Brazil, Guatemala, Italy, Luxembourg, Malta, Mexico, Peru, the Philippines, and Spain, it is the beginning of Holy Week celebrations and often termed Viernes de Dolores (Friday of Sorrows) or a similar local name. It takes place exactly one week before Good Friday, and focuses on the emotional pain the Passion of Jesus Christ caused his mother, the Blessed Virgin Mary, who is venerated under the title Our Lady of Sorrows.

An apostolic nuncio (Latin: nuntius apostolicus; also known as a papal nuncio or simply as a nuncio) is an ecclesiastical diplomat, serving as an envoy or a permanent diplomatic representative of the Holy See to a state or to an international organization. A nuncio is appointed by and represents the Holy See, and is the head of the diplomatic mission, called an apostolic nunciature, which is the equivalent of an embassy. The Holy See is legally distinct from the Vatican City or the Catholic Church. In modern times, a nuncio is usually an Archbishop.

An apostolic nuncio is generally equivalent in rank to that of ambassador extraordinary and plenipotentiary, although in Catholic countries the nuncio often ranks above ambassadors in diplomatic protocol. A nuncio performs the same functions as an ambassador and has the same diplomatic privileges. Under the 1961 Vienna Convention on Diplomatic Relations, to which the Holy See is a party, a nuncio is an ambassador like those from any other country. The Vienna Convention allows the host state to grant seniority of precedence to the nuncio over others of ambassadorial rank accredited to the same country, and may grant the deanship of that country's diplomatic corps to the nuncio regardless of seniority. The representative of the Holy See in some situations is called a Delegate or, in the case of the United Nations, Permanent Observer. In the Holy See hierarchy, these usually rank equally to a nuncio, but they do not have formal diplomatic status, though in some countries they have some diplomatic privileges.

The Dicastery for the Doctrine of the Faith (DDF) is a department of the Roman Curia in charge of the religious discipline of the Catholic Church. The Dicastery is the oldest among the departments of the Roman Curia. Its seat is the Palace of the Holy Office in Rome, just outside Vatican City. It was founded to defend the Catholic Church from heresy and is the body responsible for promulgating and defending Catholic doctrine.

This institution was founded by Pope Paul III on 21 July 1542, as the Supreme Sacred Congregation of the Roman and Universal Inquisition. It was then renamed in 1908 as the Supreme Sacred Congregation of the Holy Office. In 1965, it became the Congregation for the Doctrine of the Faith (CDF; Latin: Congregatio pro Doctrina Fidei). Since 2022, it is named Dicastery for the Doctrine of the Faith. It is still informally known as the Holy Office (Latin: Sanctum Officium) in many Catholic countries. The sole objective of the dicastery is to "spread sound Catholic doctrine and defend those points of Christian tradition which seem in danger because of new and unacceptable doctrines."
