The "status of religion" may be a strange concept for Americans, but it isn't in France (or most of western, non-Anglo-Saxon Europe).
In France (and most western European countries) every religion that is recognized as a religion by the state, gets an allowance to pay for infrastructure and priest wages.
This system was created under Napoleon after the abolishment of all church administered taxes during the French revolution. The allowance paid to recognized religions comes from the taxes paid by every citizen.
In Belgium, for example, the following religions are recognized and get a state allowance: Roman-Catholicism, Islam, Judaism, Christian-Orthodox (Russian), some reformed and some protestant Christian churches. Some pluralist and liberal organizations also get a state allowance. In Belgium, this system has created an opportunity for the Belgian Federal state to demand a the creation of consultative committee for each recognized religion.
Next to this system of recognized religions, a special investigative committee of the Belgian Federal parliament composed a list of sects and organizations dangerous to society and the individual. And yes, the CoS is on the list.
