Independent Catholicism in the context of "Old Catholic"

Western Christianity is one of two subdivisions of Christianity (Eastern Christianity being the other). Western Christianity is composed of the Latin Church and Western Protestantism, together with their offshoots such as the Old Catholic Church, Independent Catholicism and Restorationism.

The large majority of the world's 2.3 billion Christians are Western Christians (about 2 billion: 1.3 billion Latin Catholic and 1.17 billion Protestant). One major component, the Latin Church, developed under the bishop of Rome. Out of the Latin Church emerged a wide variety of independent Protestant denominations, including Lutheranism and Anglicanism, starting from the Protestant Reformation in the 16th century, as did Independent Catholicism in the 19th century. Thus, the term "Western Christianity" does not describe a single communion or religious denomination but is applied to distinguish all these denominations collectively from Eastern Christianity.

Latin liturgical rites, or Western liturgical rites, is a large family of liturgical rites and uses of public worship employed by the Latin Church, the largest particular church sui iuris of the Catholic Church, that originated in Europe where the Latin language once dominated and further by Western Rite Orthodoxy and Independent and Old Catholicism. Its language is now known as Ecclesiastical Latin. The most used rite is the Roman Rite.

The Latin rites were for many centuries no less numerous than the modern Eastern Catholic liturgical rites. The number of Latin rites and uses is now much reduced. In the aftermath of the Council of Trent, in 1568 and 1570 Pope Pius V suppressed the breviaries and missals that could not be shown to have an antiquity of at least two centuries in favor of the Roman Missal and Roman Breviary. Many local rites that remained legitimate even after this decree were abandoned voluntarily, especially in the 19th century, in favor of the Tridentine Mass and other Roman Rite rituals. In the second half of the 20th century, most of the religious orders that had a distinct liturgical rite chose to adopt in its place the Roman Rite as revised in accordance with the decrees of the Second Vatican Council (see Mass of Paul VI). A few such liturgical rites persist today for the celebration of Mass, since 1965–1970 in revised forms, but the distinct liturgical rites for celebrating the other sacraments have been almost completely abandoned.

Catholicity (from Ancient Greek: καθολικός, romanized: katholikós, lit. 'general', 'universal', via Latin: catholicus) is a concept pertaining to beliefs and practices that are widely accepted by numerous Christian denominations, most notably by those Christian denominations that describe themselves as catholic in accordance with the Four Marks of the Church, as expressed in the Nicene Creed formulated at the First Council of Constantinople in 381: "[I believe] in one, holy, catholic, and apostolic Church." The English adjective catholic is derived from the Ancient Greek adjective καθολικός (romanized: katholikos), meaning "general", "universal". Thus, "catholic" means that in the Church the wholeness of the Christian faith, full and complete, all-embracing, and with nothing lacking, is proclaimed to all people without excluding any part of the faith or any class or group of people. An early definition for what is "catholic" was summarized in what is known as the Vincentian Canon in the 5th century Commonitory: "what has been believed everywhere, always, and by all."

This is distinct from the capitalized word Catholic, referring specifically to the Catholic Church and often, further, the Roman Catholic Church, used especially in ecumenical contexts and in countries where other churches use the term catholic, to distinguish it from broader meanings of the term. Though the community led by the pope in Rome is known as the Catholic Church, the traits of catholicity, and thus the term catholic, are also ascribed to denominations such as the Eastern Orthodox Church, the Oriental Orthodox Church, and the Assyrian Church of the East. It also occurs in the language of churches that decisively split from the Roman Catholic Church, like Lutheranism and Anglicanism, as well as Independent Catholicism, Old Catholicism and other Christian denominations. While traits used to define catholicity, as well as recognition of these traits in other denominations, vary among these groups, such attributes include formal sacraments, an episcopal polity, apostolic succession, highly structured liturgical worship, and other shared Ecclesiology.

The highest-ranking bishops in Eastern Orthodoxy, Oriental Orthodoxy, the Roman Catholic Church (above major archbishop and primate), the Hussite Church, Church of the East, and some Independent Catholic Churches are termed patriarchs (and in certain cases also popes – such as the pope of Rome or pope of Alexandria).

The word is derived from Greek πατριάρχης (patriarchēs), meaning "chief or father of a family", a compound of πατριά (patria), meaning "family", and ἄρχειν (archein), meaning "to rule".

The Philippine Independent Church (Filipino: Malayang Simbahan ng Pilipinas; Ilocano: Nawaya a Simbaan ti Filipinas), officially referred to by its Philippine Spanish name Iglesia Filipina Independiente (IFI) and colloquially called the Aglipayan Church, is an independent catholic Christian denomination, in the form of a nationalist church, in the Philippines. Its revolutionary nationalist schism from the Catholic Church in the Philippines was proclaimed during the American colonial period in 1902, following the end of the Philippine–American War, by members of the country's first labor union federation, the Unión Obrera Democrática Filipina.

The foundation of the church was a response to the historical mistreatment and racial discrimination of Filipinos by Spaniard priests and partly influenced by the unjust executions of José Rizal and Filipino priests and prominent secularization movement figures Mariano Gomez, José Burgos, and Jacinto Zamora, during the former Spanish colonial rule in the country when Catholicism was still the state religion.
