I seem to recall there is, but cannot square that with the Cameron government’s intent to argue in court that two UK Christian women disciplined at work for wearing crosses have no right do so under human rights law. Excerpt:

Andrea Williams, the director of the Christian Legal Centre, said: “It is extraordinary that a Conservative government should argue that the wearing of a cross is not a generally recognised practice of the Christian faith.

“In recent months the courts have refused to recognise the wearing of a cross, belief in marriage between a man and a woman and Sundays as a day of worship as ‘core’ expressions of the Christian faith.

“What next? Will our courts overrule the Ten Commandments?”
