Lumen gentium, the Dogmatic Constitution on the Church, is one of the principal documents of the Second Vatican Council. This dogmatic constitution was promulgated by Pope Paul VI on 21 November 1964, following approval by the assembled bishops by a vote of 2,151 to 5. As is customary with significant Roman Catholic Church documents, it is known by its incipit, "Lumen gentium", Latin for "Light of the Nations".
The Latin phrase extra Ecclesiam nulla salus is a phrase referring to a Christian doctrine about who is to receive salvation.
The Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with 1.4 billion baptized Catholics worldwide as of 2019. It is among the world's oldest and largest international institutions, and has played a prominent role in the history and development of Western civilization. The church consists of 24 sui iuris churches, including the Latin Church and 23 Eastern Catholic Churches, which comprise almost 3,500 dioceses and eparchies located around the world. The pope, who is the bishop of Rome, is the chief pastor of the church. The Diocese of Rome, known as the Holy See, is the central governing authority of the church. The administrative body of the Holy See, the Roman Curia, has its principal offices in Vatican City, a small independent city-state enclave within the Italian capital city of Rome, of which the pope is head of state.
In Christian theology, ecclesiology is the study of the Church, the origins of Christianity, its relationship to Jesus, its role in salvation, its polity, its discipline, its eschatology, and its leadership.
The Angelus is a Catholic devotion commemorating the Incarnation of Christ. As with many Catholic prayers, the name Angelus is derived from its incipit—the first few words of the text: Angelus Domini nuntiavit Mariæ. The devotion is practised by reciting as versicle and response three Biblical verses narrating the mystery, alternating with the prayer "Hail Mary". The Angelus exemplifies a species of prayers called the "prayer of the devotee".
In Christian theology, the term Body of Christ has two main but separate meanings: it may refer to Jesus Christ's words over the bread at the celebration of the Jewish feast of Passover that "This is my body" in Luke 22:19–20, or it may refer to all individuals who are "in Christ" 1 Corinthians 12:12–14.
The infallibility of the Church is the belief that the Holy Spirit preserves the Christian Church from errors that would contradict its essential doctrines. It is related to, but not the same as, indefectibility, that is, "she remains and will remain the Institution of Salvation, founded by Christ, until the end of the world." The doctrine of infallibility is premised on the authority Jesus granted to the apostles to "bind and loose" and in particular the promises to Peter in regard to papal infallibility.
Catholic Mariology is Mariology in Catholic theology. According to the Immaculate Conception taught by the Catholic Church, she was conceived and born without sin, hence Mary is seen as having a singular dignity above the saints, receiving a higher level of veneration than all angelic spirits and blessed souls in heaven. Catholic Mariology thus studies not only her life but also the veneration of her in daily life, prayer, hymns, art, music, and architecture in modern and ancient Christianity throughout the ages.
The Joint Declaration on the Doctrine of Justification (JDDJ) is a document created and agreed to by the Catholic Church's Pontifical Council for Promoting Christian Unity (PCPCU) and the Lutheran World Federation in 1999 as a result of Catholic–Lutheran dialogue. It states that the churches now share "a common understanding of our justification by God's grace through faith in Christ." To the parties involved, this essentially resolves the 500-year-old conflict over the nature of justification which was at the root of the Protestant Reformation. The World Methodist Council adopted the Declaration on 18 July 2006. The World Communion of Reformed Churches, adopted the Declaration in 2017.
Catholic liturgy means the whole complex of official liturgical worship, including all the rites, ceremonies, prayers, and sacraments of the Church, as opposed to private devotions. In this sense the arrangement of all these services in certain set forms is meant. Liturgy encompasses the entire service: prayer, reading and proclamation, singing, gestures, movement and vestments, liturgical colours, symbols and symbolic actions, the administration of sacraments and sacramentals.
Subsistit in is a Latin phrase which appears in Lumen gentium, the document on the church from the Second Vatican Council of the Catholic Church. Since the council, the reason for use of the term "subsists in" rather than simply "is" has been disputed. Generally, those who see little or no change in church teaching in Vatican II insist on the equivalence of subsistit in and "is". Those who point to a new, ecumenical thrust in Vatican II insist that the term was introduced as a compromise after much discussion, and acknowledges new elements in the council's teaching.
Co-Redemptrix is a title used by some Catholics for the Blessed Virgin Mary, and refers to Mary's role in the redemption of all peoples.
Mediatrix is a title given to Mary, mother of Jesus in Christianity. It refers to the intercessory role of the Blessed Virgin Mary as a mediator in the salvific redemption by her son Jesus Christ and that he bestows graces through her. Mediatrix is an ancient title that has been used by many saints since at least the 5th century. Its use grew during the Middle Ages and reached its height in the writings of saints Louis de Montfort and Alphonsus Liguori in the 18th century.
The theology of Pope Pius XII is reflected in his forty-one encyclicals, as well as speeches and nearly 1000 messages, during his almost 20-year pontificate. The encyclicals Mystici corporis and Mediator Dei advanced the understanding of membership and participation in the Catholic Church. The encyclical Divino afflante Spiritu began opening the door to historical-critical biblical studies. But his magisterium was far larger and is difficult to summarize. In numerous speeches Catholic teaching is related to various aspects of life, education, medicine, politics, war and peace, the life of saints, Mary, the mother of God, things eternal and temporal.
The history of Catholic Mariology traces theological developments and views regarding Mary from the early Church to the 21st century. Mariology is a mainly Catholic ecclesiological study within theology, which centers on the relation of Mary, the Mother of God, and the Church. Theologically, it not only deals with her life but with her veneration in life and prayer, in art, music, and architecture, from ancient Christianity to modern times.
A dogma of the Catholic Church is defined as "a truth revealed by God, which the magisterium of the Church declared as binding". The Catechism of the Catholic Church states:
The Church's Magisterium asserts that it exercises the authority it holds from Christ to the fullest extent when it defines dogmas, that is, when it proposes, in a form obliging Catholics to an irrevocable adherence of faith, truths contained in divine Revelation or also when it proposes, in a definitive way, truths having a necessary connection with these.
The expression "one true church" refers to an ecclesiological position asserting that Jesus gave his authority in the Great Commission solely to a particular visible Christian institutional church—what is commonly called a denomination. This view is maintained by the Catholic Church, the Eastern Orthodox Church, the Oriental Orthodox communion, the Assyrian Church of the East, the Ancient Church of the East, the Christian Churches/Churches of Christ, the Churches of Christ, and the Lutheran Churches, as well as certain Baptists. Each of them maintains that their own specific institutional church (denomination) exclusively represents the one and only original church. The claim to the title of the "one true church" relates to the first of the Four Marks of the Church mentioned in the Nicene Creed: "one, holy, catholic, and apostolic church". As such, it also relates to claims of both catholicity and apostolic succession: asserting inheritance of the spiritual, ecclesiastical and sacramental authority and responsibility that Jesus Christ gave to the apostles.
The following outline is provided as an overview of and topical guide to the Catholic Church:
Criticism of Protestantism covers critiques and questions raised about Protestantism, the Christian denominations which arose out of the Protestant Reformation. While critics may praise some aspects of Protestantism which are not unique to the various forms of Protestantism, Protestantism is faced with criticism mainly from the Catholic Church and the Eastern Orthodox Church, although Protestant denominations have also engaged in self-critique and criticized one another. According to both the Catholic Church and Eastern Orthodoxy, many major, foundational Protestant doctrines have been officially declared heretical.
Catholic ecclesiology is the theological study of the Catholic Church, its nature, organization and its "distinctive place in the economy of salvation through Christ." Such study shows a progressive development over time being further described in revelation or in philosophy. Here the focus is on the time leading into and since the Second Vatican Council (1962–1965).
