The Church of Scotland officially voted to allow clergy members to perform homosexual unions.
The vote solidifies a report the denomination debated last month.
The report, put forward by the influential Theological Forum, acknowledged that the Bible condemns same-sex acts but claimed Scripture was framed by cultural context.
Marriage was redefined in Scotland in 2014, but individual churches are not required to participate in same-sex ceremonies.
Rev. Prof Iain Torrance, Convener of the Theological Forum said everyone in the Assembly was on “a spectrum of interpretation,” and suggested there was no theological reason not to allow ministers to conduct same-sex weddings.
A series of amendments put forward by supporters of biblical marriage were defeated.
The Kirk will now conduct legal research to determine how same-sex weddings in churches can be allowed.
But the report was not without opposition.
Rev. Dale London, a Church of Scotland minister in Angus, said that homosexuality was against the word of God, and that “We cannot call good what God has called evil.”
A spokesman for the Presbyterian Church in Ireland said: “many people in the Presbyterian Church in Ireland will be deeply saddened by today’s developments in Scotland, which we believe is at variance with the traditional biblical understanding of marriage between one man and one woman.”
