“Physically, the Kehilla’s German-Jewish character is immediately visible in the Synagogue. Extensive chapters in the Shulchan Aruch stress the vital importance of cleanliness, order, and dignity in the Synagogue. Thus, these aspects in themselves have little to do with a specific “German Jewishness.”
"Our Way," R' Joseph Breuer
Sounds contradictory I know. I think what he's saying here is, yes German Jewry is known for order and cleanliness and you see that in the synagogue. Nevertheless, these ideals are from halahka. Thus, we can say that the order in the synagogue isn't just German, it's halahkic and German Jews excel in it.
