Four British Christians who claim they lost their jobs as a result of discrimination against their beliefs are taking their cases to the European Court of Human Rights later.
They include an airline worker stopped from wearing a cross and a counsellor who refused to deal with gay couples.
All four lost separate employment tribunals relating to their beliefs.
The BBC's Robert Pigott says the result will mark a "watershed moment" in social change to Christian beliefs.
The cases involve British Airways check-in clerk Nadia Eweida, nurse Shirley Chaplin, relationship counsellor Gary McFarlane and registrar Lilian Ladele:http://www.bbc.co.uk/news/uk-19472438
- Ms Eweida, a Pentecostal Christian from Twickenham, south-west London, was sent home by her employer British Airways in 2006 after refusing to remove a necklace with a cross
- Devon-based nurse Mrs Chaplin was moved to a desk job by Royal Devon and Exeter NHS Trust Hospital for similar reasons
- Mr McFarlane, a Bristol counsellor, was sacked by Relate after saying he had a conscientious objection to giving relationship advice to gay people
- Ms Ladele was disciplined after she refused to conduct same-sex civil partnership ceremonies in north London
