I'm a member of the "United Reform Church". Some years ago the General Assembly debated allowing churches to perform same sex marriages. The Assembly was overwhelmingly in favour, but two delegates got it classified as a resolution that required unanimous support and blocked it. Two years later it was presented again - carefully crafted as a matter of doctrine that required a 2/3 majority and passed. Most of our churches will marry a same sex couple. When I asked to be rebaptised in my new body and name our minister at that time said she wasn't allowed to do that, then found a "Renewal of Vows" ceremony that was almost but not exactly a rebaptism.
