Intertwined or inseparable?

In his state of the Union address, Franklin D. Roosevelt says, "They know that victory for us means victory for the institution of democracy....they know that victory for us means victory for religion" (291). Are these two ideologies intertwined or inseparable?

In his book, A Cautious Patriotism, Sittser mentions that many religious leaders idealized democracy during World War II by treating it like it was its own religion or an essential part of Christian theology. Is democracy its own religion? Or is it really just an ideological source for American civil religion?
If it isn't its own religion, is it an essential part of Christianity? Could true (unforced), popular Christianity survive without democracy? Could democracy occur without Christianity?



In addition, is it democracy, is it Christianity, or is it our approach to war what has made America so unique as a country?
