In Turkey, the State pays imams' wages, and provides religious education in public schools (article 24 of that country's Constitution). The State has a Department of Religious Affairs (article 136 of the Constitution), directly under the Prime Minister bureaucratically, responsible for organizing the Muslim religion - including what will and will not be mentioned in sermons given at mosques, especially on Fridays.

Except that it isn't.

Second, the potential conflict is that if Turkey is pressured to reduce her support for Islam, then she may fairly ask why France, Germany, Britain, Spain, et al. are allowed to support their churches. At that point, who gives in? Do the French cathedrals close due to having no members, and get turned into restaurants? (As happens in the U.S.) Does England allow the next king to be Catholic?

My view is that adding such a huge new member to the EU will cause big changes on both sides--and Europe is not officially admitting it. Europe may plan to press existing EU ideals onto Turkey, but an obvious reflex will be for Turkey to press her ideals on to Europe.

Specifically, how will European countries divide the financial support that they give to churches? Will it be by population, i.e. Muslim churches get, say 70% of the government money and Christian churches get, say, 30%--because there are so few Christians? Or will Christian churches get 90% of the money because Europeans are Christians after all?

Will the EU church-supporting fund have to be significantly enlarged to fix up all those Turkish mosques that desperately need repair? After all, with Turkey's huge population, and that population almost entirely Islamic, equity demands that EU cultural maintenance be distributed in proportion.
