Those Christians and Churches which support blessing of same-sex unions do so from several perspectives:It is an affirmative good that stands alongside straight marriage and committed monastic celibacy as a revelation of God's self in the world.
The logical coherence of the core Christian doctrines such as the Trinity, the Incarnation, the Resurrection and the Ascension is improved through the integration of gay marriage into the Christian conception of marriage.
Our understanding of marriage as a metaphor of Christ’s relationship with the Church is strengthened by assimilating gay marriage into that metaphor.
Some scholars maintain that scripture in the original languages contains no prohibition of homosexuality, but does record same-sex marriage. "But if we take a closer look, reading the scripture in the original Hebrew and Greek, we discover that God never condemned homosexuality, and that same-sex marriage existed in Bible times." "To tell a homosexual that the Bible is Good News, (but that) it says that their ability to love on a one-to-one basis (mate level) means they are sinful and perverted in God's eyes is a gross contradiction in terms. What's more, God is not saying this to gay people. God's Word is this: For God so loved the world that He gave His only begotten Son that whosoever believeth in Him should not perish, but have everlasting life. (John 3:16, KJV). And that is the Good News for modern gays."
The biblic references to homosexuality were uttered in the context of promiscuous same-sex practices of Hellenistic cultures (Paul) and cultures surrounding the people of Israel (Deut). This kind of sex without love was often practiced in lieu of going to female prostitutes, also by heterosexual men. It is a discriminating misconception of our times to transfer that prohibition of such promiscuous practice without love to what we discuss here: durable, long term, choosy same-sex unions.
In 2004, the then Archbishop of Canterbury, Rowan Williams, asked the Lambeth Commission on Communion to produce a report looking into the legal and theological implications flowing from decisions related to homosexuality that were apparently threatening the Anglican Communion, including decisions relating to the blessing of same-sex unions. Once published the Windsor Report led to the calling by the Lambeth Commission for a moratorium on the blessing of same-sex unions, and recommended that bishops who have authorised such rites in the United States and Canada "be invited to express regret that the proper constraints of the bonds of affection were breached by such authorisation." The report was roundly condemned by supporters of the gay and lesbian community, as well as by a number of theologians for its partiality. To date, "the more liberal provinces that are open to changing Church doctrine on marriage in order to allow same-sex unions include Brazil, Canada, New Zealand, Scotland, South India, South Africa, the US and Wales".
Anglican Church of Canada
The General Synod of the Anglican Church of Canada in 2004 voted to defer a decision of same-sex blessings until 2007, but also to "Affirm the integrity and sanctity of committed adult same-sex relationships". In 2007, a resolution enabling diocesan bishops to authorize the blessing of same-gender unions narrowly failed, but a statement adopted by General Synod in 2010 "acknowledge[d] diverse pastoral practices as dioceses respond to their own missional contexts,"effectively devolving decisions about blessings to local dioceses.
The Anglican Church of Canada does not distinguish theologically between a marriage solemnized in church and a civil marriage subsequently blessed by a priest. Currently, three dioceses – New Westminster, Niagara, and Montréal – extend the blessing of civil marriages to same-sex couples. Procedures for blessings are in development in Ottawa and Toronto. In 2010 the General Synod of the Anglican Church of Canada voted to study a proposal to bless only those marriages that have been civilly registered, even where marriage is reserved to heterosexual couples, abrogating the role of clergy as delegates of the provincial registrar altogether.
The blessing of same-sex unions became a subject of media attention in the Vancouver area in May, 2003 when Bishop Michael Ingham of the Anglican Diocese of New Westminster announced that he had given priests in some parishes the authority to bless gay and lesbian unions. Bishop Ingham issued a rite of blessing of people in committed same-sex unions on May 23, 2003. This was done in response to requests by three consecutive Diocesan Synods, culminating in June, 2002. The diocese considers that the blessing of same-sex couples is one part of their work of community outreach and care for parishioners. The blessing is a way that some priests use to ensure that homosexual people who seek to be included in the Anglican Communion feel safe and respected. The blessing is a “pastoral tool”. Some priests in some parishes (six out of 80) bless permanent faithful relationships. Permission is granted by the bishop only when a priest requests it, and a parish has decided by majority vote, that they want to be a place of blessing. Ingham says of the practice: I insist only that those on all sides of the issue respect one another and that everyone should maintain the order of the church. Our goal in the Anglican Church in the Greater Vancouver area is to be a church that accommodates differences.
In 2009, the Anglican Diocese of Niagara in southwestern Ontario became the second diocese to authorize the blessing of same-sex unions when Bishop Michael Bird approved a gender-neutral rite for the blessing of civil marriages. The rite will be permitted for use in consultation with the diocesan bishop beginning September 1, 2009.
In 2009, the Bishop of the Anglican Diocese of Ottawa authorized the blessing of same-sex unions in a single parish: the Church of St John the Evangelist. Rather than issuing a specific rite, Bishop Chapman authorized an existing rite already in use for the blessing of civil marriages between opposite-sex couples.
In 2010, the Rt Rev'd Barry Clarke, Bishop of the Anglican Diocese of Montreal, authorized the blessing of same-sex unions. He issued a rite and guidelines to permit the blessing of civil marriages regardless of the gender of the spouses. The rite had been adapted from an existing rite already in use for the blessing of civil marriages between opposite-sex couples.
A limited number of parishes in the Anglican Diocese of Toronto have been authorized to bless same-sex unions. Rather than crafting a specific rite of blessing, the Archbishop of Toronto issued guidelines setting rules and restrictions on blessings. Blessings must not resemble too closely a marriage rite, with the specific proviso that no form of blessing used for marriage in the official rites of the Anglican Church of Canada or other parts of the Anglican Communion may be used with same-sex couples.
On July 12, 2016 the General Synod voted in favour of same-sex marriage. The Dioceses of Ottawa and Niagara, which already provide blessing rites, have announced that they will begin allowing same-sex marriages.
Episcopal Church in the USA
At its triennial General Convention in 1976, the Episcopal Church took its first official step toward the “marriage equality” it established thirty-nine years later in its 2015 General Convention as recounted below.
1976. The 1976 General Convention resolved “that it is the sense of this General Convention that homosexual persons are children of God who have a full and equal claim with all other persons upon the love, acceptance, and pastoral concern and care of the Church.”
2006. At its 2006 General Convention, the Episcopal Church rejected a resolution allowing the solemnization of same-sex marriages in Massachusetts, where same-sex marriage is recognized by civil law. However, the 2006 General Convention adopted a resolution under the title “Reaffirm Church Membership of Gay and Lesbian Persons.” The resolution was in four parts:It reaffirmed “that gay and lesbian persons are by Baptism full members of the Body of Christ and of The Episcopal Church as ‘children of God who have a full and equal claim with all other persons upon the love, acceptance, and pastoral concern and care of the Church.’”
It apologized “on behalf of The Episcopal Church to its members who are gay or lesbian, and to lesbians and gay men outside the Church, for years of rejection and maltreatment by the Church,” and recommit to “seek amendment of our life together as we ask God’s help in sharing the Good News with all people.”
It pledged “to include openly gay and lesbian persons on every committee, commission or task force developed for the specific purpose of discussing issues about sexuality and request the same of our sister churches in the Anglican Communion and Anglican Communion bodies.”
Regarding membership in the Anglican Communion, it reiterated that “our baptism into Jesus Christ is inseparable from our communion with one another, and we commit ourselves to that communion despite our diversity of opinion and, among dioceses, a diversity of pastoral practice with the gay men and lesbians among us.”
2009. In July 2009, the General Convention adopted a resolution allowing individual bishops to choose whether or not to allow the blessing of same-sex unions within their dioceses. The resolution was seen as a compromise between those who call for an official rite for the blessing of same-sex unions, and those who oppose any recognition of such unions. However, the resolution also left the door open for the creation of such an official rite in the future, calling on bishops to "collect and develop theological and liturgical resources" for possible use for such a purpose at the 2012 General Convention.
2012. On July 9, 2012, the Episcopal Church passed a resolution approving an official liturgy for blessing same-sex unions. This liturgy, called “The Witnessing and Blessing of a Lifelong Covenant” offers a blessing close to marriage, but the church is clear that it is not marriage. According to Rev. Ruth Meyers, chairwoman of the Standing Commission on Liturgy and Music, “There are a lot of similarities. The couple give their consent to being joined in lifelong commitment, they exchange vows. There’s the possibility of exchanging rings, or, for couples who have been together for some time and already have rings, to have their rings blessed. There is a blessing over the couple. But we’re clear at this point that this is not a marriage because the Episcopal Church is not in agreement in its understanding of marriage.” The resolution enables priests to bestow the church’s blessing on gay couples even if they live in a state where same-sex marriage is illegal; however, bishops who do not approve of the liturgy can prohibit their priests from using it. The resolution is provisional and will be reviewed in three years.
As of September 1, 2012, clergy of the Episcopal Diocese of New York have been authorized to officiate at same sex weddings.
2015. As the Episcopal News Service reported on the 2015 Seventy-eighth General Convention, “in the wake of the June 26 U.S. Supreme Court ruling legalizing same-sex marriage for all Americans, General Convention followed suit on July 1 with canonical and liturgical changes to provide marriage equality for Episcopalians.” A canonical change eliminated “language defining marriage as between a man and a woman” and “two new marriage rites with language allowing them to be used by same-sex or opposite-sex couples.” These new marriage rites are to be used “under the discretion and with the permission of the diocesan bishop.” Also, “clergy retain the canonical right to refuse to officiate at any wedding.”
The two new marriage rites have been made available online without charge by the Church Publishing House. “The Witnessing and Blessing of a Marriage” (Church Publishing House, 2015) and “The Celebration and Blessing of a Marriage 2" (Church Publishing House, 2015)
The General Convention also approved The Witnessing and Blessing of a Lifelong Covenant: Liturgical Resources for Blessing Same-Sex Relationships for “continued use.”
In 2013, Church of England indicated that it plans the blessing of same-sex unions. It is, however, forbidden by law to conduct same-sex marriages within its churches. The "church allows same-sex couples to have special prayers after their wedding", but does not allow gay priests to marry. Since special prayers are allowed, congregations have published and offered "Prayers for a Same Sex Commitment" or "services of thanksgiving" for same-sex couples.
For gay clergy, the church does allow civil partnerships. The church has stated, officially, that "The Church of England recognises that same-sex relationships often embody fidelity and mutuality...Civil partnerships enable these Christian virtues to be recognised socially and legally in a proper framework." While not officially allowed, some gay priests have converted their civil partnerships into legal marriages and have kept their positions.
The Church of Ireland has facilitated a number of conversations about the subject of homosexuality. In 2011, a senior minister within the church entered into a same-sex civil partnership becoming the first to do so. The Clergy Pension Fund recognized that "the pension entitlement of a member’s registered civil partner will be the same as that of a surviving spouse..." A Church of Ireland report states that "the moral logic underpinning the negative portrayal of same-sex eroticism in Scripture does not directly address committed, loving, consecrated same-sex relationships today". Currently, the church recognizes four main viewpoints ranging from opposition of same-sex unions to full acceptance of same-sex marriage.
In 2015, Scottish Episcopal Church passed an initial vote which could eventually lead to the formal blessing of same-sex unions. Following that vote, St. Paul's Cathedral in Dundee blessed a same-sex marriage for the first time. In 2016, the church voted to amend the marriage canon to include same-sex couples.
In 2015, the Church in Wales discussed same-sex marriages and "more than half of its Governing Body voted in favour of [same-sex marriage]". However, due to the need for a 2/3 majority to amend the marriage canon, the Bench of Bishops decided to approve "a series of prayers which may be said with a couple following the celebration of a civil partnership or civil marriage".
For some years, the Anglican Church of Australia has debated the blessing of same-sex marriages. Currently, the church has no official position on homosexuality. In 2013, the Diocese of Perth voted in favour of recognising same-sex relationships. The Diocese of Gippsland has appointed an openly gay priest to serve within its parishes. St. Andrew's Church in Subiaco, Perth has blessed a same-sex union.
Anglican Church in Aotearoa, New Zealand and Polynesia
In 2014, the General Synod of Anglican Church in Aotearoa, New Zealand and Polynesia passed a resolution that will create a pathway towards the blessing of same-sex relationships.
Anglican Church of Southern Africa
Some churches in Africa, "where homosexuals can be legally ordained", "are joining the trend, including the Anglican church in South Africa formerly led by Archbishop Desmond Tutu". The denomination also has no official position on homosexuality. At the same time, in 2016, "Anglican bishops from across southern Africa have resolved that gay and lesbian partners who enter same-sex civil unions under South African law should be welcomed into congregations as full members of the church".
Episcopal Anglican Church of Brazil
The Episcopal Anglican Church of Brazil permits the ordination of gay and lesbian priests and the blessing of same-sex relationships. In 2016, an Extraordinary Synod drafted a proposal for the General Synod of 2017 to amend the marriage canon to include same-sex marriage.
Four churches of the Union of Utrecht, which shares full communion with the Anglican Churches through the Bonn Agreement, also permit such blessings: namely, Old Catholic Church of the Netherlands (the mother church) permits blessings of gay civil marriages, and the Christian Catholic Church of Switzerland, and Catholic Diocese of the Old Catholics in Germany permit blessings of homosexual civil unions. The Old Catholic Church of Austria also permits such blessings. Because of this (as well as the ordination of women), the Polish National Catholic Church (USA) seceded from the Union in 2004.
Many smaller denominations, such as the Eucharistic Catholic Church, the Old Catholic Church (in Sweden) and TOCCUSA also solemnize same-sex marriages.
The Danish Church in Buenos Aires performs marriages between same-sex couples. In late 2006, the tabernacle performed the first religious wedding between a lesbian couple in Latin America.Evangelical Church in Austria
Evangelical Lutheran Free Church
Reformed Church in Austria (since 1998)
United Protestant Church in Belgium
The Evangelical Lutheran Church in Canada has permitted the blessing of same-sex unions since July 2011. The Lutheran Church–Canada does not permit the blessing of same-sex unions. The LC-C stance is consonant with that of its American sister church, the Lutheran Church–Missouri Synod.
The governing council of The United Church of Canada welcomes same-sex marriage, but individual United Church congregations are responsible for making decisions locally. Marriages are performed with the permission and under the responsibility of the local congregation.
In November 2011, the Government of Denmark announced that there will be same-sex religious marriage available in the Church of Denmark as part of the broader legislative move to recognise same sex marriage A similar debate is currently underway in the Church of Iceland following legislation to permit same sex marriage in Iceland.
The Church of Denmark (in full communion with the Anglican Churches of the British Isles through the Porvoo Communion) now performs blessings of same-sex couples.
The Evangelical Lutheran Church of Finland approved special prayers for same-sex couples following a civil union or marriage. The archbishop, who supported the prayers, "called for the church to take a clear and unequivocal stance in support of gay and lesbian couples". Some bishops are willing to ordain gay and lesbian pastors.
The United Protestant Church of France performs blessings of same-sex couples.

The Lutheran Evangelical Church in Italy supports same-sex couples and allowed blessings of same-sex unions in 2011.
In 2013, the Church of Norway allowed blessing of same-sex unions. In a synod-meeting on the 11th of April 2016 the Church of Norway formally allowed same-sex marriages in their churches and announced the commencement of work on a liturgy for same-sex marriages.
The Metropolitan Community Church of Quezon City (MCCQC), Metropolitan Community Church Makati (MCCMPH), and Metropolitan Community Church of Metro Baguio (MCCMB) officiate Holy Unions for same sex partners in the Philippines. The Metropolitan Community Church is an Ecumenical Christian Church for all people, with a special ministry to gays, lesbians, bisexuals and transgender people; it advocates for equality and social justice. Its affiliations in The Philippines are the following: MCC Quezon City, MCC Makati, MCC Metro Baguio, MCC Olongapo, and MCC Marikina.
The Church of Sweden performs blessings of same-sex couples. Following the legalization of same-sex marriage in Sweden in May 2009, the Church of Sweden decided in October 2009 to start conducting same-sex weddings in their churches. It had previously blessed same-sex couples using a different ceremony.
Some of the reformed churches in Federation of Swiss Protestant Churches perform blessings or prayers of same-sex couples, for exampleReformed Church of Aargau
Reformed Churches of the Canton Bern-Jura-Solothurn

The Evangelical Lutheran Church in America began officially allowing blessings of same-sex couples in late August, 2009—though there were no explicit prohibitions before this point. Studies and dialogue had been under way during the past decade and continued until the 2009 Churchwide Assembly, during which the ELCA passed a resolution by a vote of 619–402 reading “Resolved, that the ELCA commit itself to finding ways to allow congregations that choose to do so to recognize, support and hold publicly accountable lifelong, monogamous, same-gender relationships.” That Assembly also affirmed that sexual orientation, in itself, is not to be a qualification or exclusion for ordained ministry. As marriage policy is a congregation matter in the ELCA, same-sex partnership blessings and marriages had been performed by many Lutheran pastors prior to the 2009 actions. In 1993 the ELCA Conference of Bishops stated it did not approve of such ceremonies, but made no comment about same-sex marriage. (The Conference of Bishops is an advisory body of the ELCA.)
Lutheran congregations which so choose may register their public affirmation for gay, lesbian, bisexual, and transgender people may register with Lutherans Concerned/North America, a church advocacy group, as "Reconciling in Christ." This registry includes not only congregations, but synods, organizations, Lutheran colleges, campus ministries, social ministry institutions, Lutheran health care organizations, campus ministries, church colleges, regional synods and districts, and other groups which openly welcome gays and lesbians in their communities. The national Lutheran organization which advocates for equality for gays and lesbians inside and outside the church is known as "Lutherans concerned North America". Founded in 1974 Local chapters are found throughout the USA and Canada.
The 2006 General Assembly of the Church of Scotland voted that blessing civil partnerships should be a matter of conscience for individual ministers. Conservatives in the Kirk argued that the reform would have to be ratified by local presbyteries. When the 45 Presbyteries were consulted, only nine voted in favour of allowing ministers to bless civil-partnered (same-sex) couples, and the remaining 36 were against the innovation. Therefore, it was defeated, and is due to be addressed again at the 2013 General Assembly. At its 2011 General Assembly, the Church of Scotland voted to allow openly gay and lesbian Ministers and Diaconal ministers who live in civil unions, provided that they were already ordained and had declared their sexuality before the Scott Rennie case on 23 May 2009. There remains, however, a Moratorium (legal term for a ban) on accepting those in same-sex relationships for training, ordination or induction into the Ministry or Diaconate, which may be lifted by the General Assembly of 2013. When asked to respond to the Scottish Government's consultation on same-sex marriage, the Church's Legal Questions Committee submitted a response which upheld a biblical and traditional understanding of marriage as a voluntary lifelong union between one man and one woman (December 2011). After this, the Church's first openly gay minister, Revd. Scott Rennie, claimed to the press that such ostracisation of homosexuals will empty churches.
In 2016, the General Assembly voted in favor of allowing ministers to enter into same-sex marriages.
In May 2006, a church spokesperson announced that clergy could bless same-gender partnerships. However, that announcement was reversed by General Assembly when it voted to ban its ministers from blessing same-gender partnerships in June 2006. The Presbyterian Church in Ireland is currently strongly opposed to same sex marriage.
The Presbyterian Church USA General Assembly Permanent Judicial Commission ruled in 2006 that same-sex ceremonies are not forbidden, as long as they are not considered to be the same as marriage services. Debate on the issue within the church evolved over the years. In 2000, the General Assembly had approved language for the church constitution that stated church teachings were that people were “to live either in fidelity within the covenant of marriage between a man and a woman or in chastity in singleness.," and barred church officers and property from being used for blessing or approval upon any other form of fidelity relationship, but ratification for this language was never obtained by the presbyteries. By 2014, the General Assembly passed an Authoritative Interpretation permitting pastors to sign marriage licences for same-gender couples where permitted by civil law in the states where their church was found, which took immediate effect.
On March 17, 2015, ratification by a majority of presbyteries was reached on a constitutional amendment passed by that same 2014 General Assembly, which broadened the definition of marriage in the Directory for Worship from only being between “a man and a woman,” to “two people, traditionally a man and a woman,” thus giving official sanction to, while not making it mandatory for, any congregation's pastor to preside over and bless marriage ceremonies for same-gender couples.
There are a variety of responses within Methodism some of which have been favorable to a greater or lesser extent to same-sex unions or marriages.
Methodist Church of Great Britain
In 2005, the Methodist Church of Great Britain voted to allow a local option for ministers who wish to perform same-sex blessings, with a Church spokesperson stating that “We have decided, with the law changing in December, we as a Church need to provide guidance to our ministers, who will be allowed to take an individual decision as to whether or not they want to bless gay couples.” In 2006, the Church reversed itself and prohibited the blessing of same-sex unions on or off church property. Ministers are still at liberty to offer informal, private prayers for such couples. However, in 2014, the church allowed ministers to enter into same-sex marriages and to offer celebratory services for same-sex marriages.
United Methodist Church
The United Methodist Church currently prohibits celebrations of same-sex unions by its elders and in its churches. However, while "clergy cannot preside over the wedding ceremony...bishops say, clergy can assist same-gender couples in finding other venues for their wedding; provide pre-marital counseling; attend the ceremony; read Scripture, pray or offer a homily". Moreover, the church approved spousal benefits for non-ordained employees in same-sex marriages in states that allow such marriages.
The church does not nationally allow the ordination of gay or lesbian pastors, but some Jurisdictions and Annual Conferences have begun to ordain gay and lesbian pastors and same-sex marriages or have passed resolutions supporting such ceremonies. The Baltimore-Washington, California-Nevada, California-Pacific, Desert Southwest, Detroit, Greater New Jersey, Great Plains, Illinois Great Rivers, Iowa, Minnesota, New England, New York, Northern Illinois, Oregon-Idaho, Pacific Northwest, Rocky Mountain, Southwest Texas, Upper New York, Virginia, West Michigan, and Wisconsin Annual Conferences have passed resolutions supporting same-sex couples or the ordination of gay and lesbian clergy.
In 2016, the New York Annual Conference ordained the denomination's first openly gay and lesbian clergy. Following those ordinations, the Western Jurisdiction elected and consecrated the church's first openly gay and partnered bishop.
African Methodist Episcopal Church
The African Methodist Episcopal Church, which is in full communion with the UMC, currently prohibits its ministers from officiating same-sex weddings, but it does not have an official policy on gay pastors and, therefore, gay ministers have been ordained in the AME.
Evangelical Methodist Church in Argentina
The Evangelical Methodist Church in Argentina allows "the freedom to accompany homosexual couples" in ministry. Each congregation is, therefore, free to determine its own policy.
Evangelical Methodist Church in Uruguay
The Evangelical Church in Uruguay, a Methodist denomination, has "resolved that pastors that wish to minister to homosexuals may do so freely". Each pastor is free to provide blessing services for same-sex unions if he or she chooses to do so.
Methodist Church of New Zealand
In 2004, the Methodist Church of New Zealand approved the ordination of gay and lesbian clergy; each congregation is able to determine its own position on the issue.
The Alliance of Baptists has in the past supported the legal right to marry; its position on corollary church services is unclear. The Cooperative Baptist Fellowship nationally opposes same-sex marriage, but its local congregations remain free to discern the issue for themselves and many congregations have pledged to perform same-sex weddings. Additionally, congregations of the American Baptist Churches USA are locally autonomous and free to support same-sex marriages if they so choose.
The first recorded same sex marriage by a Quaker meeting in the US was in 1987. In January, 1987, Morningside Monthly Meeting of the Society of Friends became the first Quaker Meeting to take a same-sex marriage (using the word marriage, rather than "commitment ceremony") under its care with the marriage of John Bohne and William McCann on May 30, 1987.
Same-sex couples have been married under the care of many "unprogrammed" Quaker meetings in Canada since 1992. In Australia, Canberra Quaker meeting celebrated the marriage of two gay men on 15 April 2007. Australian Quakers are prepared to celebrate same-sex marriages despite the lack of legal recognition. See Quaker views of homosexuality
In 2009, the Yearly Meeting of the Religious Society of Friends (Quakers) in Great Britain, the Channel Islands and the Isle of Man decided to authorise same-sex marriage, having previously performed blessings for same-sex civil partnerships. In Australia, the 2010 Yearly Meeting called on the Federal Government to amend the Australian Marriage Act to give full and equal legal recognition to all marriages, regardless of the sexual orientation and gender of the partners. Australian Quakers had been blessing same-sex unions since 1994. The Canada Yearly Meeting stated in 2003 that Canadian Quakers "support the right of same-sex couples to a civil marriage and the extension of the legal definition of marriage to include same-sex couples." Since then a number of same-sex marriages have been performed at Canadian Monthly Meetings. In New Zealand, the Aotearoa Quaker Meeting in 1995 pledged “to seek formal ways of recognizing a variety of commitments, including gay and lesbian partnerships.”
Varies by church. The General Synod of the United Church of Christ has passed a resolution affirming "equal marriage rights for couples regardless of gender and declares that the government should not interfere with couples regardless of gender who choose to marry and share fully and equally in the rights, responsibilities and commitment of legally recognized marriage". At its 25th General Synod in 2005, the UCC passed the resolution, "Equal Marriage Rights for All". However, the polity of the UCC is congregationalist, so of each church has a different way of operating. (The General Synod does not have authority over Local Churches to determine or enforce denominational doctrine)
Canadian Unitarian churches perform same-sex marriage as well.
Unitarian Universalists perform same-sex marriages, and have supported marriage equality since 1973, reaffirming with a formal resolution in 1996.
The predominantly gay Universal Fellowship of Metropolitan Community Churches performs same-sex marriages.
The Mennonite Church in the Netherlands offers marriage to both heterosexual and same-gender couples.
The Mennonite Church Canada offers marriag to both heterosexuel and same-gender couples.
The Remonstrants perform weddings for both heterosexual and same-sex couples.
Most Pentecostal churches do not affirm gay marriage.
The Affirming Pentecostal Church International and the Global Alliance of Affirming Apostolic Pentecostals are US based denominations of Oneness Pentecostals that will perform weddings for both heterosexual and same-sex couples.
In mainline Christian Church (Disciples of Christ) blessing of same-sex unions are allowed.
The Moravian Church in North America's Northern Province has passed several liberal resolutions on homosexuality, but has not yet been able to "address the issue of a marriage covenant between homosexual persons".
The Swedenborgian Church of North America allows ministers to choose whether to perform same-sex marriages.
In Australia the Uniting Church in Australia allows blessing of same-sex unions.
The Protestant Church in the Netherlands has chosen not to address marriage in its post-merger canon law; however, the by-laws of the church allow for the blessing of relationships outside of marriage.
Due to its "local option", a number of congregations and ministers of the United Church of Canada (a merger of Congregationalist, Presbyterian and Methodist congregations in Canada following presbyterian polity) officiate at same-sex marriages, which are fully legal in Canada.
Since 2011 in Europe the New Apostolic Church allows blessings in a prayer for same-sex unions.
By nature of this religious understanding of marriage, when churches use the term "Union" in a same-sex blessing ceremony, they may or may not be blessing this union in an equivalent way as they would bless a "marriage" as opposed to blessing the commitment between the two individuals. Some Christian bodies are exploring the manner in which same-sex couples could or should be blessed (or not) by the church. Because same-sex religious unions are not widespread and because civil unions do not require religious officiation, documentation of the incidence of church blessing of same-sex couples is difficult.
During the 1990s, a discussion began in the Roman Catholic Church about blessings for same-sex unions. Central teaching remains clear that such unions can in no ways be sanctioned by the Catholic Church. However, there are exceptions when individual priests carry out informal blessings. They risk being disciplined if the blessing is discovered. In the Roman Catholic Diocese of Aachen in Germany, five same-sex unions received a blessing in German town of Mönchengladbach. In 2007, one same-sex union received a blessing in German town of Wetzlar in the Roman Catholic Diocese of Limburg. In October 2014 a blessing of a same-sex union took place in Bürglen, Uri, Switzerland. The priest subsequently made a public apology. A blessing of a same-sex union, equivalent to marriage except name, took place by a Catholic Dominican priest in Malta in 2015. In May 2015 the Central Commiitee of German Catholics voted in favour of blessing of same-sex unions.
The United Church of Christ has no formal rules requiring or prohibiting solemnization of wedding vows, but owing to its Congregational polity and constitution, each Local Church is "autonomous in the management of its own affairs" and has the "right to operate in the way customary to it"; it cannot be "abridge[d] or impair[ed]" by other UCC agencies, and so each congregation has the freedom to bless or prohibit any kind of marriage or relationship in whatever way they discern appropriate. Thus a congregation may choose at their discretion to solemnise same-sex marriages, to bless same-sex unions, or refuse to perform any ceremony for same-sex couples, or refuse to perform any kind of marriage for anyone. There are no available statistics on how many UCC congregations solemnize same-sex relationships, but there are documented cases where this happens and documented cases where congregations have taken stands against marriage between same-gender couples.
Among Baptists, The American Baptist Churches USA allows each congregation to decide for itself. Also, "the National Baptist Convention USA Inc. does not have an "official" position on any issues with regards to homosexuality". Each congregation is autonomous in the National Baptist Convention USA Inc.. Likewise, the Cooperative Baptist Fellowship recognizes the autonomy of each local congregation on these issues.
The Christian Church (Disciples of Christ) allows each congregation to decide whether to perform same-sex marriages.
