The UK Government is currently consulting on whether to allow same-sex [civil] marriage. It is the stated policy of the current (Coalition) Government that same-sex marriage be legislated for and the Prime Minister, David Cameron, has stated that he is personally in favour of same-sex marriage because he is a Conservative, not despite being a Conservative.
I have signed the petition organised by the Coalition for Equal Marriage calling for same-sex marriage to be legislated for - you can sign the C4EM petition here.
I have also completed the Home Office consultation survey - you can complete it too, by visiting the relevant part of the Home Office website here.
The legislative proposals put forward by the Government provide only for same-sex 'Civil' marriage, in other words it does not contemplate allowing same-sex marriage in a religious context, even where a particular religious organisation would be happy to do so. I think this is wrong and that religious organisations which wish to do so should be allowed to. I do not think that any religious organisation should be forced to conduct same-sex marriages if this would be in conflict with its theology - any more than certain religious organisations currently are forced to conduct heterosexual marriages under certain circumstances which they find objectionable (e.g. the Roman Catholic Church will not consecrate marriages where one partner is divorved or has a former marriage partner who remains alive). However, the legislative proposals by the Government are a huge step forward and should be strongly supported, even if they are perhaps not the ideal solution.
I urge you strongly to sign the petition and to complete the Home Office Consultation survey without delay!
