In a significant election development, UKIP has promised legal protection for Christians holding to the biblical understanding of marriage.
The commitment comes in a 'Christian Manifesto' issued by the party, entitled 'Valuing our Christian heritage.'
In it, UKIP's leader Nigel Farage MEP writes: "I have been saying for a long time that we need a much more muscular defence of our Christian heritage ... we believe Christianity should be recognised by Government at all levels.
"Sadly, I think UKIP is the only major political party left in Britain that still cherishes our Judaeo-Christian heritage. I believe other parties have deliberately marginalised our nation's faith, whereas we take Christian values and traditions into consideration when making policy."
The document goes on to outline 'where UKIP stands on Christian issues'.
In a section on marriage, the party promises:
"We will also extend the legal concept of 'reasonable accommodation' to give protection in law to those expressing a religious conscience in the workplace on this issue."
'Reasonable accommodation' requires employers to make allowances for a person's conscience and religious identity unless they can show that doing so would place an undue burden on the employing organisation.
The Christian Legal Centre has long argued that 'reasonable accommodation' would be an important first step in securing better protection of Christian freedom and resolving the so-called 'clash of rights' that has seen many cases come to court in recent years.
Chief executive, Andrea Williams, said:
"All our Christian freedom cases in recent years could have been resolved quickly and simply if 'reasonable accommodation' had been practised.
"So it is a big step forward that one of the major parties is calling for it to be enshrined in law. Now we need the other parties to catch up and echo this commitment ahead of the election."
Earlier this year, the Parliamentary Assembly of the Council of Europe called on member states to practise reasonable accommodation.
Last week, Ed Miliband promised to look into 'Christian freedoms' and the challenges faced by UK Christians in the work-place and community service.
But UKIP's policy commitment goes further still and will be welcomed by Christians across the country who have been raising the issue with their local candidates.
'The Power of the Cross' initiative
The document also responds to other issues raised by Christian voters through Christian Concern's 'Power of the Cross' initiative - including assisted suicide, abortion, sex education and the place of Britain's Christian heritage.
As part of the 'Power of the Cross' initiative, Christian Concern has distributed half a million postcards to supporters and provided other tools to help Christians question their candidates on foundational issues.
