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.
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 Lutheran Church of Sweden has performed full same-sex marriages beginning since November 2009. It previously blessed same-sex couples using a different ceremony.[6]
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[7] A similar debate is currently underway in the Church of Iceland following legislation to permit same sex marriage in Iceland[8].
The predominantly gay Universal Fellowship of Metropolitan Community Churches performs same-sex marriages.[9]
The Mennonite Church in the Netherlands offers marriage to both heterosexual and same-gender couples.[10]
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.[11]
The Unitarian Universalists perform same-sex marriages.[12]
The Swedenborgian Church of North America allows ministers to choose whether to perform same-sex marriages.[13]
Same-sex couples have been married under the care of many "unprogrammed" Quaker meetings in Canada since 1992.[14] British Quaker meetings celebrate same-sex commitments by a special act of worship but none has yet called this marriage. In Australia, Canberra Quaker meeting celebrated the marriage of two gay men on 15 April 2007.[15][16][17][18] Australian Quakers are prepared to celebrate same-sex marriages despite the lack of legal recognition.[19] See Quaker views of homosexuality
Many smaller denominations, such as the Eucharistic Catholic Church and the Old Catholic Church (in Sweden)[20] also solemnize same-sex marriages.
