This system of Turkish laïcité permeates both the government and the religious sphere. The content of the weekly sermons in all state-funded mosques has to be approved by the state. Also, independent Sunni communities are illegal. Minority religions, like Armenian or Greek Orthodoxy, are guaranteed by the constitution as "individual" faiths and are mostly tolerated, but this guarantee does not give any rights to any "religious communities" including Muslim ones. Turkey's view is that the Treaty of Lausanne gives certain religious rights to Jews, Greeks, and Armenians but not, for example, to Syrian-Orthodox or Roman Catholics, because the latter ones did not play any political roles during the treaty. However, the Treaty of Lausanne does not specify any nationality or ethnicity and simply identifies non-Muslims in general.
