In the case of German churches, I'm pretty convinced they are just trying to do the right thing. In the 60s when we had a lot of turks coming in for labor, they even let them use one wing of the Cologne cathedral as an Ersatz mosque.
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
Psalm 14, KJV revised edition
