That creepy line, according to Jonah Goldberg's Liberal Fascism, was part of a Hitler Youth song popular during the late 1930s. Goldberg has posted two excerpts from his book in response to the idea, still widely prevalent, that Hitler was a Christian of some sort or another (a strong Catholic, according to some):
Like the engineers of that proverbial railway bridge, the Nazis
worked relentlessly to replace the nuts and bolts of traditional
Christianity with a new political religion. The shrewdest way to accomplish
this was to co-opt Christianity via the Gleichschaltung
while at the same time shrinking traditional religion’s role in civil society.
To this end, Hitler was downright Bismarckian. The German
historian Götz Aly explains how Hitler purchased popularity with
lavish social welfare programs and middle-class perks, often paid for
with stolen Jewish wealth and high taxes on the rich. Hitler banned
religious charity, crippling the churches’ role as a counterweight to
the state.
