There is nothing unusual about this, except for the fact that Germany's state support extends to a plurality of churches rather than just one. Before the disestablishment of state churches, it was natural and common for the state to support the Church, including through taxation and mandatory tithes. My Greek friend informs me that Eastern Orthodoxy is still run this way, but more straightforward since there is only one established Church to fund and operate. I am not sure how many other Orthodox nations support their established Church through taxation, but yeah, it's normal.
