In June 2016, the Scottish Episcopal Church became the first British province in the Anglican Communion to take steps to allow same-sex marriages to be performed in their churches. The General Synod voted in favour of a motion to begin discussion amongst the seven dioceses to remove the doctrinal clause which stated that marriage was between a man and a woman. The vote received support from five of seven bishops, 69% of the clergy and 80% of the laity. The General Synod formally approved the change to the doctrinal clause in June 2017, removing language stating that marriages could only be between a man and a woman and introducing a new conscience clause which allows clergy to opt out of performing same-sex weddings. On 20 July 2017, it was announced that a same-sex wedding was to be held in St Mary's Cathedral, Glasgow, later in the summer. On 1 August 2017, a same-sex marriage, which included the Eucharist as a nuptial mass, was held at the Church of St John the Evangelist, Edinburgh. The Scottish Episcopal Church is estimated to have 100,000 members, and offers same-sex marriage to other Anglicans, including members of churches in England and the United States.
