I think Hitler himself wasn't much of a church goer, but there is at least one picture (found here) of him darkening the door...
Caption: A photograph accidentally becomes a symbol. Adolf Hitler, the supposed "heretic," leaves the Marine Church in Wilhelmshaven.
You see, its been our misfortune to have the wrong religion. Why didnt we have the religion of the Japanese, who regard sacrifice for the Fatherland as the highest good? The Mohammedan religion too would have been much more compatible to us than Christianity. Why did it have to be Christianity with its meekness and flabbiness? -- Hitler quoted by Albert Speer. Inside the Third Reich. 1970 p.96
