This is a list of Independent Catholic denominations , current and defunct, which identify as Catholic but are not in communion with the Holy See.
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 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.
The terms Old Catholic Church, Old Catholics, Old-Catholic churches, or Old Catholic movement, designate "any of the groups of Western Christians who believe themselves to maintain in complete loyalty the doctrine and traditions of the undivided church but who separated from the see of Rome after the First Vatican council of 1869–70".
Ultramontanism is a clerical political conception within the Catholic Church that places strong emphasis on the prerogatives and powers of the Pope. It contrasts with Gallicanism, the belief that popular civil authority—often represented by the monarch's or state's authority—over the Church is comparable to that of the Pope.
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.
Greek Orthodox Church is a term that can refer to any one of three classes of Christian churches, each associated in some way with Greek Christianity, Levantine Arabic-speaking Christians or more broadly the rite used in the Eastern Roman Empire.
The Continuing Anglican movement, also known as the Anglican Continuum, encompasses a number of Christian churches, principally based in North America, that have an Anglican identity and tradition but are not part of the Anglican Communion.
Independent Catholicism is an independent sacramental movement of clergy and laity who self-identify as Catholic and form "micro-churches claiming apostolic succession and valid sacraments", in spite of not being affiliated to the historic Catholic church, the Roman Catholic church. The term "Independent Catholic" derives from the fact that "these denominations affirm both their belonging to the Catholic tradition as well as their independence from Rome".
The Charismatic Episcopal Church (CEC), officially the International Communion of the Charismatic Episcopal Church (ICCEC), is a Christian denomination established in 1992. The ICCEC is a part of the Convergence Movement. Within North America, most of the Charismatic Episcopal Church's congregations and missions are located within the Northern, Southeastern, Midwest, and Western United States; it also has a presence in Texas, and in Western Canada.
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.
Branch theory is an ecclesiological proposition that the One, Holy, Catholic, and Apostolic Church includes various different Christian denominations whether in formal communion or not. The theory is often incorporated in the Protestant notion of an invisible Christian Church structure binding them together.
The Convergence Movement, also known as the Ancient-Future Faith, whose foundation is primarily attributed to Robert E. Webber in 1985, is an ecumenical movement. Developed as an effort among evangelical, charismatic and Pentecostal, and liturgical Christians and denominations blending their forms of worship, the movement has been defined for its predominant use of the Anglican tradition's Book of Common Prayer; use from additional liturgical sources common to Lutheranism, Eastern Orthodoxy, and Catholicism have also been employed.
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 Oriental Orthodox Churches are Eastern Christian churches adhering to Miaphysite Christology, with approximately 50 million members worldwide. The Oriental Orthodox Churches adhere to the Nicene Christian tradition. Oriental Orthodoxy is one of the oldest branches in Christianity.
