Some Christians support religious and legal recognition of same-sex marriages based on a moral commitment to equality, or a belief that "human sexual orientations, whether heterosexual, bisexual or homosexual, are a gift from God", as affirmed by the United Church of Canada's 37th General Council.
Even within the Roman Catholic Church, there can be found a few a groups who support for same-sex marriage.
Not a single Bible text indisputably refers to lesbian sex.
According to the MCC, biblical texts interpreted by some as references to homosexuality refer only to specific sex acts and idolatrous worship which lack relevance to contemporary same-sex relationships.
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 also progressive congregations and organizations within mainline Christian denominations, that have not yet officially voiced official support for same-sex marriage, but have spoken out themselves in support of equal marriage rights in the church and through the state.
Some biblical scholars who hold to a more theologically liberal Christian view of same-sex marriage, such as representatives of the Metropolitan Community Church, make the claim that the word "homosexual" as found in many modern versions of the Bible is an interpolation and is not found in the original biblical texts.
