"The folkish-minded man, in particular, has the sacred duty,
   each in his own denomination, of making people stop just
   talking superficially of God's will, and actually fulfill
   God's will, and not let God's word be desecrated.

   "For God's will gave men their form, their essence, and their
   abilities. Anyone who destroys His work is declaring war on
   the Lord's creation, the divine will. Therefore, let every
   man be active, each in his own denomination if you please,
   and let every man take it as his first and most sacred duty
   to oppose anyone who in his activity by word or deed steps
   outside the confines of his religious community and tries
   to butt into the other."

Adolf Hitler, from Mein Kampf, translation by Ralph Mannheim.
