America's most recent two dominant civil religions
Our nation's civil religions have been the religion of the plurality or even the majority for a long time. Of that pantheon, the dominant deity post-WWII was the "God" of anti-communism, patriotism, and nationalism-- the god instilled in our pledge and on our money. (Of course, followers of the Triune God would say that they see their own God represented on those mediums.)
In recent days, our culture's newly-dominant civil religion has become what Christian Smith termed "Moral Therapeutic Deism"-- here defined by Dreher as "a vague, vapid approach to religion, one that can be summed up as: God exists, and he wants us to be nice to each other, and to be happy and successful."
