"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.
