rq turtle/ttl

But this is quite tricky and I couldn't write a good query for it. Could someone help? Here a bad written query (it's limited to churches - or it TimeOut - and to 2 countries, and it's still quite long to give results) :

PREFIX wikibase: <http://wikiba.se/ontology#>
PREFIX wdt: <http://www.wikidata.org/prop/direct/>

SELECT ?item ?itemLabel ?country1Label ?country2Label
WHERE {
  ?item wdt:P31 wd:Q16970 ; wdt:P17 ?country1 ; wdt:P17 ?country2 .
  MINUS { ?country1 wdt:P47 ?country2 }
  FILTER ( ?country1 != ?country2 )
  FILTER NOT EXISTS { ?country1 wdt:P576 [] }
  FILTER NOT EXISTS { ?country2 wdt:P576 [] }
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
}
