The Anglican Communion is the third largest Christian communion after the Roman Catholic and Eastern Orthodox churches. Founded in 1867 in London, the communion has more than 85 million members within the Church of England and other autocephalous national and regional churches in full communion. The traditional origins of Anglican doctrine are summarised in the Thirty-nine Articles (1571). The archbishop of Canterbury in England acts as a focus of unity, recognised as primus inter pares, but does not exercise authority in Anglican provinces outside of the Church of England. Most, but not all, member churches of the communion are the historic national or regional Anglican churches.

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.

The Catholic–Lutheran dialogue is a series of discussions that began during July 1964 as an outgrowth of the Second Vatican Council.

These dialogues have been primarily between representatives of the Lutheran World Federation and representatives of the Pontifical Council for Promoting Christian Unity.
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 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."
Lutheranism is present on all inhabited continents with an estimated 80 million adherents, out of which 74.2 million are affiliated with the Lutheran World Federation. A major movement that first began the Reformation, it constitutes one of the largest Protestant branches claiming around 80 million out of 920 million Protestants. The Lutheran World Federation brings together the vast majority of Lutherans. Apart from it, there are also other organisations such as the International Lutheran Council and the Confessional Evangelical Lutheran Conference, as well as multiple independent Lutheran denominations.
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 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":
