Hello,

The church is mapped as https://www.openstreetmap.org/way/43806428. I added the address, thank you! Its name is in the database, so all is correct on that front. If the name is not displayed on the default layer of openstreetmap.org, it's a matter of rendering, which we can't really control (possibly because the renderer wants to fit the entire name inside the building and it's a rather long name). Because it's in the databases, it'll show up when searching, and can be viewed on its details page (https://www.openstreetmap.org/way/43806428).
