So it appears the choice is between having Catholic Church and Nazi Germany on one side and on the other side a pair of articles about Pius XI and Germany and Pius XII and Germany  I dont like the focus on each Pope  There is a story about the relationship between the Church and Nazi Germany which is perhaps A Tale of Two Popes  However if this tale is split up into two articles Pius XI and Germany and Pius XII and Germany it becomes harder to find and follow  Of course since Wikipedia is not paper we could simply agree to have a content fork and let all three articles exist  That would suggest that you could recreate the Pius XII and Germany article using some text from here and adding back the material about postWWII relations between the Church and the two Germanys  I do think that Catholic bishops in Nazi Germany should be merged into this article
