Full communion

Last updated

Full communion is a communion or relationship of full understanding among different Christian denominations 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.

A Christian denomination is a distinct religious body within Christianity, identified by traits such as a name, organization, leadership and doctrine. The Catholic Church, Eastern Orthodox Church and Oriental Orthodoxy, meaning the large majority, all self-describe as churches, whereas many Protestant denominations self-describe as congregations or fellowships. Divisions between one group and another are defined by authority and doctrine; issues such as the nature of Jesus, the authority of apostolic succession, 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.

Christian theology is the theology of Christian belief and practice. Such study concentrates primarily upon the texts of the Old Testament and of the New Testament, as well as on Christian tradition. Christian theologians use biblical exegesis, rational analysis and argument. Theologians may undertake the study of Christian theology for a variety of reasons, such as in order to:

Eucharist Christian rite

The Eucharist is a Christian rite that is considered a sacrament in most churches, and as an ordinance in others. According to the New Testament, the rite was instituted by Jesus Christ during the Last Supper; giving his disciples bread and wine during the Passover meal, Jesus commanded his followers to "do this in memory of me" while referring to the bread as "my body" and the cup of wine as "the new covenant in my blood". Through the Eucharistic celebration Christians remember both Christ's sacrifice of himself on the cross and his commission of the apostles at the Last Supper.


Definition and terminology

In the view of the World Council of Churches, an inter-church organization that includes "most of the world's Orthodox churches, scores of Anglican, Baptist, Lutheran, Methodist and Reformed churches, as well as many United and Independent churches", [1] "the goal of the search for full communion is realized when all the churches are able to recognize in one another the one, holy, catholic and apostolic church in its fullness", a communion "given and expressed in the common confession of the apostolic faith; a common sacramental life entered by the one baptism and celebrated together in one eucharistic fellowship; a common life in which members and ministries are mutually recognized and reconciled; and a common mission witnessing to all people to the gospel of God's grace and serving the whole of creation". [2]

World Council of Churches Worldwide inter-church organization founded in 1948

The World Council of Churches (WCC) is a worldwide Christian inter-church organization founded in 1948. Its members today include the Assyrian Church of the East, the Oriental Orthodox Churches, most jurisdictions of the Eastern Orthodox Church, the Mar Thoma Syrian Church of Malabar, the Old Catholic Church, the Anglican Communion, most mainline Protestant churches and some evangelical Protestant churches. Notably, the Catholic Church is not a member, although it sends accredited observers to meetings. The WCC arose out of the ecumenical movement and has as its basis the following statement:

The World Council of Churches is a fellowship of churches which confess the Lord Jesus Christ as God and Savior according to the scriptures, and therefore seek to fulfill together their common calling to the glory of the one God: Father, Son and Holy Spirit.

It is a community of churches on the way to visible unity in one faith and one eucharistic fellowship, expressed in worship and in common life in Christ. It seeks to advance towards this unity, as Jesus prayed for his followers, "so that the world may believe."

Baptists Denomination of Protestant Christianity

Baptists form a major branch of Protestant Christianity distinguished by baptizing professing believers only, and doing so by complete immersion. Baptist churches also generally subscribe to the doctrines of soul competency, sola fide, sola scriptura and congregationalist church government. Baptists generally recognize two ordinances: baptism and communion.

Protestant churches

Several Protestant denominations base their idea of full communion on the Augsburg Confession which says that "the true unity of the church" is present where "the gospel is rightly preached and sacraments rightly administered." They believe that full communion between two denominations is not a merger, they respect each other's differences, but rather it's when two denominations develop a relationship based on a mutual understanding and recognition of Baptism and sharing of the Lord's Supper. They may worship together, exchange clergy, and share commitments to evangelism and service. [3]

Augsburg Confession primary confession of faith of the Lutheran Church and one of the most important documents of the Protestant Reformation

The Augsburg Confession, also known as the Augustan Confession or the Augustana from its Latin name, Confessio Augustana, is the primary confession of faith of the Lutheran Church and one of the most important documents of the Protestant Reformation. The Augsburg Confession was written in both German and Latin and was presented by a number of German rulers and free-cities at the Diet of Augsburg on 25 June 1530.

Baptism Christian rite of admission and adoption, almost invariably with the use of water

Baptism is a Christian rite of admission and adoption, almost invariably with the use of water, into Christianity. The synoptic gospels recount that John the Baptist baptised Jesus. Baptism is considered a sacrament in most churches, and as an ordinance in others. Baptism is also called christening, although some reserve the word "christening" for the baptism of infants. It has also given its name to the Baptist churches and denominations.

Evangelism Spreading the Gospel of Jesus Christ for the purpose of conversion to or a rapprochement with Christianity

In Christianity, evangelism is the commitment to or act of publicly preaching (ministry) of the Gospel with the intention of spreading the message and teachings of Jesus Christ.

Groups recognized as being in full communion with each other on this basis include the Presbyterian Church (USA), Reformed Church in America, United Church of Christ, The Episcopal Church (United States), the Moravian Church, the Evangelical Lutheran Church, and the United Methodist Church. [3]

Presbyterian Church (USA) Mainline Protestant Christian denomination in the USA

The Presbyterian Church (USA) is a mainline Protestant Christian denomination in the United States. A part of the Reformed tradition, it is the largest Presbyterian denomination in the US, and known for its relatively progressive stance on doctrine. The PC(USA) was established by the 1983 merger of the Presbyterian Church in the United States, whose churches were located in the Southern and border states, with the United Presbyterian Church in the United States of America, whose congregations could be found in every state. The similarly named Presbyterian Church in America is a separate denomination whose congregations can also trace their history to the various schisms and mergers of Presbyterian churches in the United States.

Reformed Church in America

The Reformed Church in America (RCA) is a mainline Reformed Protestant denomination in Canada and the United States. It has about 196,308 members, with the total declining in recent decades. From its beginning in 1628 until 1819, it was the North American branch of the Dutch Reformed Church.

United Church of Christ Protestant Christian denomination

The United Church of Christ (UCC) is a mainline Protestant Christian denomination based in the United States, with historical confessional roots in the Congregational, Reformed, and Lutheran traditions, and with approximately 4,956 churches and 853,778 members. The United Church of Christ is a historical continuation of the General Council of Congregational Christian churches founded under the influence of New England Pilgrims and Puritans. Moreover, it also subsumed the third largest Reformed group in the country, the German Reformed. The Evangelical and Reformed Church and the General Council of the Congregational Christian Churches united in 1957 to form the UCC. These two denominations, which were themselves the result of earlier unions, had their roots in Congregational, Lutheran, Evangelical, and Reformed denominations. At the end of 2014, the UCC's 5,116 congregations claimed 979,239 members, primarily in the U.S. In 2015, Pew Research estimated that 0.4 percent, or 1 million adult adherents, of the U.S. population self-identify with the United Church of Christ.

The United Church of Christ (UCC) defines full communion as meaning that "divided churches recognize each others' sacraments and provide for the orderly transfer of ministers from one denomination to another." Some of these go back to the 17th century Pilgrims in Holland; other relationships are recent. The UCC is in full communion alliance with the members of the World Alliance of Reformed Churches, the Union of Evangelical Churches in Germany, the Presbyterian Church (USA), and several others in North America and elsewhere. [4]

The World Alliance of Reformed Churches (WARC) was a fellowship of more than 200 churches with roots in the 16th-century Reformation, and particularly in the theology of John Calvin. Its headquarters was in Geneva, Switzerland. They are now merged into the World Communion of Reformed Churches.

Union of Evangelical Churches

The Union Evangelischer Kirchen is an organisation of 13 United and Reformed evangelical churches in Germany, which are all member churches of the Evangelical Church in Germany.

Anglican Communion

The Anglican Communion distinguishes between full communion and intercommunion. It applies the first term to situations "where between two Churches, not of the same denominational or confessional family, there is unrestricted communio in sacris including mutual recognition and acceptance of ministries", and the second term to situations "where varying degrees of relation other than full communion are established by agreement between two such Churches". [5] This distinction differs from the distinction that the Catholic Church makes between full and partial communion in that the Anglican concept of intercommunion implies a formal agreement entered into by the churches concerned. The Anglican understanding of full communion differs from that of the Roman Catholic Church and Eastern Christianity, which consider that full communion between churches involves them becoming a single church, as in the case of the particular churches "in which and formed out of which the one and unique Catholic Church exists", [6]

Anglican Communion International association of churches

The Anglican Communion is the third largest Christian communion. Founded in 1867 in London, England, the communion currently has 85 million members within the Church of England and other national and regional churches in full communion. The traditional origins of Anglican doctrines 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.

Catholic Church Largest Christian church, led by the Bishop of Rome

The Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with approximately 1.3 billion baptised Catholics worldwide as of 2017. As the world's oldest and largest continuously functioning international institution, it has played a prominent role in the history and development of Western civilisation. The church is headed by the Bishop of Rome, known as the pope. Its central administration, the Holy See, is in the Vatican City, an enclave within the city of Rome in Italy.

In addition the Anglican Communion recognizes the possibility of full communion between some of its member provinces or churches and other churches, without having the entire Anglican Communion share that relationship. [7] An example is the Porvoo Communion.

The Anglican Communion established full communion with the Old Catholic Churches on the basis of the 1931 Bonn Agreement, which established three principles:

  1. Each communion recognizes the catholicity and independence of the other and maintains its own.
  2. Each communion agrees to admit members of the other communion to participate in the sacraments.
  3. Full communion does not require from either communion the acceptance of all doctrinal opinion, sacramental devotion or liturgical practice characteristic of the other, but implies that each believes the other to hold all the essentials of the Christian faith. [8] [9]

The Anglicans Online website provides a list of non-Anglican churches "in full communion with the See of Canterbury" and also indicates some important ecumenical agreements of local character (i.e., not involving the whole of the Anglican Communion) with other non-Anglican churches. [7] It also lists churches that, in spite of bearing names (such as "Anglican" or "Episcopal") that might suggest a relationship with the Anglican Communion, are not in communion with it. [10]

Catholic Church

Full and partial communion

The Catholic Church makes a distinction between full and partial communion: where full communion exists, there is but one church; partial communion, on the other hand, exists where some elements of Christian faith are held in common, but complete unity on essentials is lacking. Accordingly, it sees itself as in partial communion with Protestants and in much closer, but still incomplete, communion with the Orthodox churches. It has expressed this distinction in documents such as Unitatis redintegratio , the Second Vatican Council's decree on ecumenism, which states: "... quite large communities came to be separated from full communion with the Catholic Church ... men who believe in Christ and have been truly baptized are in communion with the Catholic Church even though this communion is imperfect". [11]

The Catechism of the Catholic Church , citing the Second Vatican Council and Pope Paul VI, states:

"The Church knows that she is joined in many ways to the baptized who are honoured by the name of Christian, but do not profess the Catholic faith in its entirety or have not preserved unity or communion under the successor of Peter" (Lumen gentium 15). Those "who believe in Christ and have been properly baptized are put in a certain, although imperfect, communion with the Catholic Church" (Unitatis redintegratio 3). With the Orthodox Churches, this communion is so profound "that it lacks little to attain the fullness that would permit a common celebration of the Lord's Eucharist" (Paul VI, Discourse, 14 December 1975; cf. Unitatis redintegratio 13-18). [12]

Full communion involves completeness of "those bonds of communion faith, sacraments and pastoral governance that permit the Faithful to receive the life of grace within the Church." [13]

Universal and particular Churches

In Catholicism, the "universal Church" means Catholicism itself, from the Greek adjective καθολικός (katholikos), meaning "universal". [14] The term particular church denotes an ecclesiastical community headed by a bishop or equivalent, and this can includes both local dioceses as well as autonomous (or sui juris) particular churches, which include other rites such as the Latin Church and the Eastern Catholic Churches. [15]

The particular Churches that form the Catholic Church are each seen, not as a separate body that has entered into practical arrangements concerning its relations with the others, but as the embodiment in a particular region or culture of the one Catholic Church.

A 1992 Congregation for the Doctrine of the Faith (CDF) letter to Catholic bishops expressed this idea as: "the universal Church cannot be conceived as the sum of the particular Churches, or as a federation of particular Churches. It is not the result of the communion of the Churches, but, in its essential mystery, it is a reality ontologically and temporally prior to every individual particular Church." [16]

List of Catholic churches in full communion

The autonomous Catholic churches in full communion with the Holy See are:

Churches in partial communion

The Catholic Church sees itself as in partial, not full, communion with other Christian groups. "With the Orthodox Churches, this communion is so profound 'that it lacks little to attain the fullness that would permit a common celebration of the Lord's Eucharist.'" [12]

Sharing in the Eucharist

As a practical matter for most Catholics, full communion means that a member of one Church may partake of the Eucharist celebrated in another, [17] and for priests, that they are accepted as celebrants of the Eucharist in the other Church.

Restrictions in this matter were already in force in the second century as witnessed to by Justin Martyr in his First Apology : "No one is allowed to partake (of the Eucharist) but the man who believes that the things which we teach are true, and who has been washed with the washing that is for the remission of sins, and unto regeneration, and who is so living as Christ has enjoined." [18]

For acceptance into full communion with the Catholic Church a specific profession of the faith of the Catholic Church is required even of those who have been members of a separate church whose sacraments the Catholic Church considers to be valid. [17] [19] Being "in full communion with the Catholic Church" requires that they "firmly accept" its teaching on faith and morals. [20]

Intercommunion usually means an agreement between churches by which all members of each church (clergy with clergy, or laity with laity, respectively) may participate in the other's Eucharistic celebrations or may hold joint celebrations. [21] The Catholic Church has entered into no such agreement: it allows no Eucharistic concelebration by its clergy with clergy of churches not in full communion with it. [lower-alpha 2]

The Directory for the Application of Principles and Norms on Ecumenism, indicates the limited circumstances in which Catholics may receive the Eucharist from clergy of churches not in full communion (never if those churches are judged not to have valid apostolic succession and thus valid Eucharist), and in which Catholic clergy may administer the sacraments to members of other churches. [24] (nn. 122–136)

The norms there indicated for the giving of the Eucharist to other Christians (communicatio in sacris) are summarized in canon 844 of the Latin Church's 1983 Code of Canon Law. [25] The Code of Canons of the Eastern Churches (CCEO) indicates that the norms of the Directory apply also to the clergy and laity of the Eastern Catholic Churches. [26]

Eastern and Oriental Orthodox churches and Church of the East

Eastern Orthodox and Oriental Orthodox Christians have an understanding of what full communion means that is very similar to that of the Catholic Church.[ citation needed ] Though they have no figure corresponding to that of the Roman Catholic Pope, performing a function like that of the Pope's Petrine Office for the whole of their respective communions, they see each of their autocephalous churches as embodiments of, respectively, the One, Holy, Catholic and Apostolic Church. They too consider full communion an essential condition for common sharing in the Eucharist. The Ecumenical Patriarch of Constantinople, as first among equals among the Eastern Orthodox autocephalous churches, though not having authority similar to that of the Roman Catholic Pope, serves as their spokesman. The Pope of the Coptic Orthodox Church of Alexandria holds a somewhat similar position in Oriental Orthodoxy.

For the autocephalous churches that form the Eastern Orthodox Church, see Eastern Orthodox Church organization. Their number is somewhat in dispute.

The Oriental Orthodox churches are:

The Church of the East is currently divided into churches that are not in full communion with one another. The Assyrian Church of the East and the Ancient Church of the East divided in the 20th century over the former's limitation of the post of patriarch to members of a single family [27] and due to the adoption of the New Calendar by the former. There is movement towards reunity, but they are not in full communion with one another at present. The Chaldean Catholic Church shares a similar history with both, but is currently in full communion with neither. The Catholic Church, of which the Chaldean Church is part, allows its ministers to give the Eucharist to members of Eastern churches who seek it on their own accord and are properly disposed, and it allows its faithful who cannot approach a Catholic minister to receive the Eucharist, when necessary or spiritually advantageous, from ministers of non-Catholic churches that have a recognised Eucharist. [28] [25]

The Guidelines for Admission to the Eucharist between the Chaldean Church and the Assyrian Church of the East explicitly apply these rules, which hold also for the Ancient Church of the East and all the Oriental and Eastern Orthodox churches, to the Assyrian Church of the East. [29] "When necessity requires, Assyrian faithful are permitted to participate and to receive Holy Communion in a Chaldean celebration of the Holy Eucharist; in the same way, Chaldean faithful for whom it is physically or morally impossible to approach a Catholic minister, are permitted to participate and to receive Holy Communion in an Assyrian celebration of the Holy Eucharist". [29]

Other churches

Churches or denominations holding to open communion allow all persons who consider themselves "Christian believers" to participate, even without any arrangement of full communion with the other church or denomination involved, and still less requiring an arrangement involving interchangeability of ordained ministers.

It is in the stronger sense of becoming a single church that in 2007 the Traditional Anglican Communion sought "full communion" with the Roman Catholic Church as a sui iuris (particular Church) jurisdiction, but in 2012 declined the possibility offered by Pope Benedict XVI to join a personal ordinariate for former Anglicans in full communion with the see of Rome. [30]

Of the various Latin liturgical rites used within the Latin particular Church, even those associated not with a religious order but with a geographical area do not constitute separate particular Churches. Thus there is no Ambrosian particular Church corresponding to the Ambrosian Rite in use in Milan and neighbouring areas of Italy and Switzerland, nor is there a Mozarabic particular Church in those parts of Spain where the Mozarabic Rite is practiced. In the Latin Church, governance is uniform, even where liturgical rite is not.

Holy orders sacraments of the Catholic Church

In the Christian churches, holy orders are ordained ministries such as bishop, priest, or deacon, and the sacrament or rite by which candidates are ordained to those orders. Churches recognizing these orders include the Catholic Church, the Eastern Orthodox, Oriental Orthodox, Anglican, Assyrian, Old Catholic, Independent Catholic and some Lutheran churches. Except for Lutherans and some Anglicans, these churches regard ordination as a sacrament. The Anglo-Catholic tradition within Anglicanism identifies more with the Roman Catholic position about the sacramental nature of ordination.

Mass (liturgy) type of worship service within many Christian denomination

Mass is the main eucharistic liturgical service in many forms of Western Christianity. The term Mass is commonly used in the Roman Catholic and Anglican churches, as well as in some Lutheran, Methodist, Western Rite Orthodox, and Old Catholic churches.

Confirmation rite where baptism is confirmed in several Christian denominations

In Christian denominations that practice infant baptism, confirmation is seen as the sealing of Christianity created in baptism. Those being confirmed are known as confirmands. In some denominations, such as the Anglican Communion and Methodist Churches, confirmation bestows full membership in a local congregation upon the recipient. In others, such as the Roman Catholic Church, confirmation "renders the bond with the Church more perfect", because, while a baptized person is already a member, "reception of the sacrament of Confirmation is necessary for the completion of baptismal grace".

Blessed Sacrament devotional name for the body and blood of Christ

The Blessed Sacrament, also Most Blessed Sacrament, is a devotional name used in the Latin Church of the Catholic Church, as well as in Anglicanism, Lutheranism, Methodism, and the Old Catholic Church, as well as in some of the Eastern Catholic Churches, to refer to the body and blood of Christ in the form of consecrated sacramental bread and wine at a celebration of the Eucharist. In the Byzantine Rite, the terms Holy Gifts and Divine Mysteries are used to refer to the consecrated elements. Christians in these traditions believe in the Real Presence of Jesus Christ in the Eucharistic elements of the bread and wine and some of them, therefore, practice Eucharistic reservation and adoration. This belief is based on interpretations of both scripture and sacred tradition. The Catholic understanding has been defined by numerous ecumenical councils, including the Fourth Lateran Council and the Council of Trent, which is quoted in the Catechism of the Catholic Church.

A rite is an established, ceremonial, usually religious, act. Rites in this sense fall into three major categories:

Closed communion

Closed communion is the practice of restricting the serving of the elements of Holy Communion to those who are members in good standing of a particular church, denomination, sect, or congregation. Though the meaning of the term varies slightly in different Christian theological traditions, it generally means that a church or denomination limits participation either to members of their own church, members of their own denomination, or members of some specific class. See also intercommunion.

Open communion

Open communion is the practice of some Protestant Churches of allowing members and non-members to receive the Eucharist. Many but not all churches that practice open communion require that the person receiving communion be a baptized Christian, and other requirements may apply as well. In Methodism, open communion is referred to as the open table.

Real presence of Christ in the Eucharist in Christianity, the doctrine that Jesus Christ is really or substantially present in the Eucharist, not merely symbolically or metaphorically

The real presence of Christ in the Eucharist is a term used in Christian theology to express the doctrine that Jesus is really or substantially present in the Eucharist, not merely symbolically or metaphorically.

Low church Christian denominations without much ritual

"Low church" Christian denominations are those who give relatively little emphasis to ritual, sacraments and the authority of clergy. The term is most often used in a liturgical context.

Christian liturgy is a pattern for worship used by a Christian congregation or denomination on a regular basis. Although the term liturgy is used to mean public worship in general, the Byzantine Rite uses the term "Divine Liturgy" to denote the Eucharistic service.

Words of Institution

The Words of Institution are words echoing those of Jesus himself at his Last Supper that, when consecrating bread and wine, Christian Eucharistic liturgies include in a narrative of that event. Eucharistic scholars sometimes refer to them simply as the verba.

Infant communion

Infant communion refers to the practice of giving the Eucharist, often in the form of consecrated wine, to young children. This practice is standard in the Eastern Orthodox Church and the Eastern Catholic Churches; here, communion is given at the Divine Liturgy to all baptized and chrismated church members regardless of age. Infant communion is less common in most other Christian denominations, including the Latin Rite of the Catholic Church.

Charismatic Episcopal Church

The Charismatic Episcopal Church, more officially known as the International Communion of the Charismatic Episcopal Church (ICCEC), is an international Christian denomination established as an autocephalous communion in 1992. The ICCEC states that it is not a splinter group of any other denomination or communion, but is a convergence of the sacramental, evangelical, and charismatic traditions that it perceives in the church from the apostolic era until present times.

Catholicity is a concept pertaining to beliefs and practices widely accepted across numerous Christian denominations, most notably those that describe themselves as Catholic in accordance with the Four Marks of the Church, as expressed in the Nicene Creed of the First Council of Constantinople in 381: "[I believe] in one, holy, catholic, and apostolic Church."

Catholic Church and ecumenism

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. Before that time, those outside of the Catholic Church were categorised as heretics or schismatics.

Anglican Communion and ecumenism

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":

Liturgical book Christian prayer book

A liturgical book, or service book, is a book published by the authority of a church body that contains the text and directions for the liturgy of its official religious services.

Sacrament sacred rite recognized as of particular importance and significance

A sacrament is a Christian rite recognized as of particular importance and significance. There are various views on the existence and meaning of such rites. Many Christians consider the sacraments to be a visible symbol of the reality of God, as well as a means by which God enacts his grace. Many denominations, including the Catholic, Anglican, Lutheran, Methodist, and Reformed, hold to the definition of sacrament formulated by Augustine of Hippo: an outward sign of an inward grace that has been instituted by Jesus Christ. Sacraments signify God's grace in a way that is outwardly observable to the participant.
