Apostolic succession is the method whereby the ministry of the Christian Church is considered by some Christian denominations to be derived from the apostles by a continuous succession, which has usually been associated with a claim that the succession is through a series of bishops. Those of the Catholic, Eastern Orthodox, Scandinavian Lutheran, Anglican, Oriental Orthodox, Church of the East, Hussite, Moravian, and Old Catholic traditions maintain that "a bishop cannot have regular or valid orders unless he has been consecrated in this apostolic succession". These traditions do not always consider the episcopal consecrations of all of the other traditions as valid.
An ecumenical council, also called general council, is a meeting of bishops and other church authorities to consider and rule on questions of Christian doctrine, administration, discipline, and other matters in which those entitled to vote are convoked from the whole world (oikoumene) and which secures the approbation of the whole Church.
An episcopal polity is a hierarchical form of church governance in which the chief local authorities are called bishops. The word "bishop" here is derived via the British Latin and Vulgar Latin term *ebiscopus/*biscopus, from the Ancient Greek ἐπίσκοπος epískopos meaning "overseer". It is the structure used by many of the major Christian Churches and denominations, such as the Catholic, Eastern Orthodox, Oriental Orthodox, Church of the East, Anabaptist, Lutheran, and Anglican churches or denominations, and other churches founded independently from these lineages. Many Methodist denominations have a form of episcopal polity known as connexionalism.
Full communion is a communion or relationship of full agreement among different Christian denominations or Christian individuals that share certain essential principles of Christian theology. Views vary among denominations on exactly what constitutes full communion, but typically when two or more denominations are in full communion it enables services and celebrations, such as the Eucharist, to be shared among congregants or clergy of any of them with the full approval of each.
Ecumenism – also called interdenominationalism, or ecumenicalism – is the concept and principle that Christians who belong to different Christian denominations should work together to develop closer relationships among their churches and promote Christian unity. The adjective ecumenical is thus applied to any non-denominational or inter-denominational initiative which encourages greater cooperation and union among Christian denominations and churches. Ecumenical dialogue is a central feature of contemporary ecumenism.
Ash Wednesday is a holy day of prayer and fasting in many Western Christian denominations. It is preceded by Shrove Tuesday and marks the first day of Lent, the six weeks of penitence before Easter.
A Christian denomination is a distinct religious body within Christianity that comprises all church congregations of the same kind, identifiable by traits such as a name, particular history, organization, leadership, theological doctrine, worship style and, sometimes, a founder. It is a secular and neutral term, generally used to denote any established Christian church. Unlike a cult or sect, a denomination is usually seen as part of the Christian religious mainstream. Most Christian denominations refer to themselves as churches, whereas some newer ones tend to interchangeably use the terms churches, assemblies, fellowships, etc. Divisions between one group and another are defined by authority and doctrine; issues such as the nature of Jesus, the authority of apostolic succession, biblical hermeneutics, theology, ecclesiology, eschatology, and papal primacy may separate one denomination from another. Groups of denominations—often sharing broadly similar beliefs, practices, and historical ties—are sometimes known as "branches of Christianity". These branches differ in many ways, especially through differences in practices and belief.
Reformation Day is a Protestant Christian religious holiday celebrated on 31 October in remembrance of the onset of the Reformation.
The Taizé Community is an ecumenical Christian monastic community in Taizé, Saône-et-Loire, Burgundy, France. It is composed of about one hundred brothers, from Catholic and Protestant traditions, who originate from about thirty countries around the world. It was founded in 1940 by Brother Roger Schütz, a Reformed Protestant. Guidelines for the community's life are contained in The Rule of Taizé written by Brother Roger and first published in French in 1954.
Christian liturgy is a pattern for worship used by a Christian congregation or denomination on a regular basis. The term liturgy comes from Greek and means "public work". Within Christianity, liturgies descending from the same region, denomination, or culture are described as ritual families.
The term Evangelical Catholic is used in Lutheranism, alongside the terms Augsburg Catholic or Augustana Catholic, with those calling themselves Evangelical Catholic Lutherans or Lutherans of Evangelical Catholic churchmanship stressing the catholicity of historic Lutheranism in liturgy, beliefs, practices, and doctrines. Evangelical Catholics teach that Lutheranism at its core "is deeply and fundamentally catholic". The majority of Evangelical Catholic Lutheran clergy and parishes are members of mainstream Lutheran denominations.
High church Lutheranism is a movement that began in 20th-century Europe and emphasizes worship practices and doctrines that are similar to those found within Roman Catholicism, Eastern Orthodoxy and Anglo-Catholicism. In the more general usage of the term, it describes the general high church characteristics of Lutheranism in Nordic and Baltic countries such as Sweden, Finland, Estonia and Latvia. The mentioned countries, once a part of the Swedish Empire, have more markedly preserved Catholic traditions.
Catholicity 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, 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."
The Catholic Church has engaged in the modern ecumenical movement especially since the Second Vatican Council (1962–1965) and the issuing of the decree Unitatis redintegratio and the declaration Dignitatis humanae. It was at the Council that the Pontifical Council for Promoting Christian Unity was created. Those outside of the Catholic Church were categorised as heretics or schismatics, but in many contexts today, to avoid offence, the euphemism "separated brethren" is used.
Anglican interest in ecumenical dialogue can be traced back to the time of the Reformation and dialogues with both Orthodox and Lutheran churches in the sixteenth century. In the nineteenth century, with the rise of the Oxford Movement, there arose greater concern for reunion of the churches of "Catholic confession". This desire to work towards full communion with other denominations led to the development of the Chicago-Lambeth Quadrilateral, approved by the Third Lambeth Conference of 1888. The four points were stipulated as the basis for church unity, "a basis on which approach may be by God's blessing made towards Home Reunion":
The Communion of Protestant Churches in Europe is a fellowship of over 100 Protestant churches which have signed the Leuenberg Agreement. Together they strive for realizing church communion, especially by cooperation in witness and service to the world. Prior to 2003 the CPCE was known as the "Leuenberg Church Fellowship".
Pope Benedict XVI, who led the Roman Catholic Church as Pope from 2005 to 2013, continued manoeuvring the Church through the dynamics of modernity, which the Church had begun engaging in with the Second Vatican Council. Because the question of religious pluralism is a key issue raised by modernity, ecumenism, the establishment of harmony and dialogue between the different Christian denominations, is a significant concern of a post Second Vatican Council Church. Pope Benedict XVI's approach has been characterised as leaning toward the conservative while still being expansive and engaged, involving the full breadth of Christendom, including the Orthodox Churches and Protestant churches, as well as freshly engaging with other Christian bodies considered by Roman Catholics to be more heterodox, such as the Church of Jesus Christ of Latter-day Saints.
The Protestant Church of the Augsburg Confession of Alsace and Lorraine is a Lutheran church of public-law corporation status in France. The ambit of the EPCAAL comprises congregations in Alsace and the Lorrain Moselle department.
The history of Christian flags encompasses the establishment of Christian states, the Crusader era, and the 20th century ecumenical movement.
