The Pope says the EU is "ignoring its Christian roots" and was therefore on the road to oblivion caused by "a singular form of apostasy".
I may be the wrong person to comment as an atheist but - quite apart from a large number of the founding fathers of the EU having been secular democratic socialists - wouldn't a specifically "Christian" EU be a completely alienating concept for millions of Jewish and Muslim Europeans?
According to the BBC the Muslim population of EU member states includes:
Austria - 339,000 (4.1%)
Belgium - 0.4m (4%)
Denmark - 270,000 (5%)
France - between 5 and 6m (8-9.6%)
Germany - 3m (3.6%)
Italy - 825,000 (1.4%)
Netherlands - 945,000 (5.8%)
Spain - 1m (2.3%)
Sweden - 200,000 (3%)
UK - 1.6m (2.8%)
These 14m people are Europeans - as are millions of atheists, Jews, Hindus, Sikhs etc. - the EU is not the property of one faith. The values of democracy and liberty that Europe shares are universal ones, not the exclusive property of one faith-based civilisation.
The deeply divisive attempt to define the EU as a specifically culturally Christian group of states is behind French and German moves to block Turkish EU membership.
Well done to French Socialist Presidential Candidate Segolene Royal for having the courage to say that opposition to Turkish EU membership is wrong.
