USGS has removed man-made structures (in which churches and towers meet the criteria) from the GNIS in 2021 (see https://www.usgs.gov/faqs/does-geographic-names-information-system-gnis-include-manmade-and-administrative-features-such). Searching the GNIS ID of such features in their search tool (https://edits.nationalmap.gov/apps/gaz-domestic/public/search/names) will return no results.
