Plenty of Unitarian churches out there that will happily perform the ceremonies, no need to force other churches or temples to perform a ceremony the congregation doesn’t want performed.
When the Equality Bill was being debated earlier this year, an amendment was added by Lord Alli that permitted civil partnership ceremonies to take place in places of worship if the relevant religious group permitted it.............
Quakers, Unitarians and the Liberal Judaism movement will ask to be allowed to host the ceremonies but the Church of England will resist it, despite the wishes of some liberal clerics, as will the Roman Catholic Church in England and Wales.
Thats exactly why they want it. They are advancing their agenda. They want to go into territory where they haven't been allowed.
