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.
Called to Common Mission (CCM) is an agreement between The Episcopal Church (ECUSA) and the Evangelical Lutheran Church in America (ELCA) in the United States, establishing full communion between them. It was ratified by the ELCA in 1999, the ECUSA in 2000, after the narrow failure of a previous agreement. Its principal author on the Episcopal side was theological professor J. Robert Wright. Under the agreement, they recognize the validity of each other's baptisms and ordinations. The agreement provided that the ELCA would accept the historical episcopate and the "threefold ministry" of bishop - priest - deacon with respect to ministers of communicant churches serving ELCA congregations; the installation of the ELCA presiding bishop was performed through the laying on of hands by Lutheran bishops in the historic episcopate. This provision was opposed by some in the ELCA, which after its founding merger in 1988, held a lengthy study of the ministry which was undertaken with divided opinions. In response to concerns about the meaning of the CCM, synod bishops in the ELCA drafted the Tucson resolution which presented the official ELCA position. It made clear that there is no requirement to ordain deacons or accept their ministry. It also provided assurance that the ELCA did not and was not required by CCM to change its own theological stance.
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 Church of Sweden is an Evangelical Lutheran national church in Sweden. A former state church, headquartered in Uppsala, with around 5.4 million members at year end 2023, it is the largest Christian denomination in Sweden, the largest Lutheran denomination in Europe and the third-largest in the world, after the Ethiopian Evangelical Church Mekane Yesus and the Evangelical Lutheran Church in Tanzania.
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 initiative that encourages greater cooperation and union among Christian denominations and churches.
Ordination is the process by which individuals are consecrated, that is, set apart and elevated from the laity class to the clergy, who are thus then authorized to perform various religious rites and ceremonies. The process and ceremonies of ordination vary by religion and denomination. One who is in preparation for, or who is undergoing the process of ordination is sometimes called an ordinand. The liturgy used at an ordination is commonly found in a book known as an Ordinal which provides the ordo for celebrations.

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.
Catholicity is a concept of 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 Evangelical Lutheran Church of Latvia is a Lutheran Protestant church in Latvia. Latvia's Lutheran heritage dates back to the Reformation. Both the Nazi and communist regimes persecuted the church harshly before religious freedom returned to Latvia in 1988. In contrast to Estonia, where state atheism reduced the once 80% Lutheran majority to barely 10% by 2011, the Latvian Lutheran church saw its membership drop to around 20% but has recovered and now includes approximately 30% of the population. The church reports having 250,000 members according to the Lutheran World Federation.
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.
The term Eastern Protestant Christianity encompasses a range of heterogeneous Protestant Christian denominations that developed outside of the Western world, from the latter half of the nineteenth century, and retain certain elements of Eastern Christianity. Some of these denominations came into existence when active Protestant churches adopted reformational variants of Eastern and Oriental Orthodox liturgy and worship, while others originated from Orthodox groups who were inspired by the teachings of Western Protestant missionaries and adopted Protestant beliefs and practices.
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.
