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.
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 initiative that encourages greater cooperation and union among Christian denominations and churches.
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.
Johannes Gerardus Maria Willebrands was a Dutch Cardinal of the Roman Catholic Church. He served as President of the Pontifical Council for Promoting Christian Unity from 1969 to 1989, and Archbishop of Utrecht from 1975 to 1983. Elevated to the cardinalate in 1969, Willebrands was central to the increased ecumenism of the Church in the second half of the 20th century, and was considered papabile at the two conclaves held in 1978.
The Christian Catholic Church of Switzerland is an Old Catholic denomination in Switzerland. This denomination is part of the Union of Utrecht.
The Union of Utrecht of the Old Catholic Churches, most commonly referred to by the short form Union of Utrecht (UU), is a federation of Old Catholic Churches, nationally organized from schisms which rejected Roman Catholic doctrines of the First Vatican Council in 1870; its member churches are not in communion with the Roman Catholic 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.
The September 14–16, 1977 Congress of St. Louis was an international gathering of nearly 2,000 Anglicans in St. Louis, Missouri, united in their rejection of theological changes introduced by the Anglican Church of Canada and by the Episcopal Church in the United States of America in its General Convention of 1976. Anglicans who attended this congress felt that these changes amounted to foundational alterations in the American and Canadian provinces of the Anglican Communion and meant that they had "departed from Christ's One, Holy, Catholic and Apostolic Church." Theological liberalism, financial support for political action groups, participation in the Consultation on Church Union (COCU), revisions to the Book of Common Prayer, and the ordination of women priests were not the only reasons for the split, but they were seen by these churches as evidence of the mainline church's departure from Anglican orthodoxy. The idea for a congress originated with the Reverend Canon Albert J. duBois in 1973 in preparation for the Louisville General Convention of the Episcopal Church. Canon duBois and the group called "Anglicans United" toured parishes in advance of the Congress to garner support. This congress was sponsored by the Fellowship of Concerned Churchmen, an organization founded in 1973 as a coordinating agent for laypeople and clergy concerned about the breakdown of faith and order within the Episcopal Church and the Anglican Church of Canada.
The historic or historical episcopate comprises all episcopates, that is, it is the collective body of all the bishops of a group who are in valid apostolic succession. This succession is transmitted from each bishop to their successors by the rite of Holy Orders. It is sometimes subject of episcopal genealogy.

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.
Anglican–Roman Catholic dialogue is the historical communication between the Anglican Communion and the Roman Catholic Church, through their ecumenical relations. These were notably shaped subsequent to the Second Vatican Council (1962–1965).
A personal ordinariate for former Anglicans, shortened as personal ordinariate or Anglican ordinariate, is a canonical structure within the Catholic Church established in order to enable "groups of Anglicans" and Methodists to join the Catholic Church while preserving elements of their liturgical and spiritual patrimony.
