From the BBC:
The Quakers – also known as The Religious Society of Friends – are likely to reach consensus on the issue of gay marriage without a vote at their annual gathering in York on Friday.
They will also formally ask the government to change the law to allow gay people to marry.
Quaker registrars, like rabbis and Church of England priests, have the authority to marry heterosexual couples on behalf of the state.But many British Quakers feel it is wrong to exclude a religious commitment from civil partnerships and want the right to marriage extended to same-sex couples too.
The Quakers has welcomed same-sex unions for more than two decades, allowing local groups to celebrate same-sex commitments through special acts of worship.
