Apostolic succession is the method whereby the ministry of the Christian Church is held 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 Anglican, Church of the East, Eastern Orthodox, Hussite, Moravian, Old Catholic, Oriental Orthodox, Catholic and Scandinavian Lutheran 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.
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, transdenominationalism, 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 interdenominational initiative that encourages greater cooperation and union among Christian denominations and churches.
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, alongside All Hallows' Eve (Halloween) during the triduum of Allhallowtide, in remembrance of the onset of the Reformation.
The Taizé Community is an ecumenical Christian monastic fraternity in Taizé, Saône-et-Loire, Burgundy, France. It is composed of more than 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 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.
The term Evangelical Catholic is used in Lutheranism, alongside the term Augsburg 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 both Roman Catholicism, Eastern Orthodoxy and the High church wing of Anglicanism. In the more general usage of the term, it describes the general high church characteristics of Lutheranism in the 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 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 manouevring 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.
Protestantism is a branch of Christianity that follows the theological tenets of the Protestant Reformation, a movement that began in the 16th century with the goal of reforming the Catholic Church from perceived errors, abuses, and discrepancies.
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.
