From Occupy Wall Street to the National Association of Evangelicals, there are echoes of what was called the social gospel a hundred years ago.

This movement coined the phrase, what would Jesus do?

And for three years running, its pivotal text by its leading figure, Walter Rauchin Bush, sold more copies than any religious book after the Bible.

Rauchin Bush called for Christians to be at the forefront of social renewal, healing that era's social crisis.

But his subject headings alone sound oddly present, the morale of the workers, the physical decline of the people, the wedge of inequality.

Fast forward to today, and Walter Rauchin Bush's great-grandson Paul Rauchin Bush is the religion editor of The Huffington Post.

We have some fun this hour. We learn some things about re-emerging strains in the DNA of Christianity.

And we take in a counterintuitive view of religion and culture from an emerging realm of our time.

Paul Rauchin Bush likes to recall a complaint from a blogger named Grumpy to one of his posts on The Huffington Post.

Now I have seen it all. The Huff Post asking what would be the correct thing to do from a religious standpoint.

I cannot believe I am seeing this on The Huff Post.

Paul Rauchin Bush replied, well-grumpy, believe it.

People are surprised, but that's my standard line. This is good, but it could be a little more religion-y.

And by religion-y, I just mean go deep into your tradition. Don't be shy about it.

Paul Brandeis Rauchin Bush has been senior religion editor of The Huffington Post since that section's launch in 2010.

He also spent nine years as Chaplin and Associate Dean of Religious Life at Princeton University.

He grew up in Madison, Wisconsin, where Walter Rauchin Bush's son settled with his wife, who happened to be the daughter of Louis Brandeis, the first Jewish Supreme Court Justice.

Despite his noble lineage, Paul says, he only distinguished himself religiously in his early years by being the first person to flunk out of Presbyterian confirmation.

And you, of course, had in your DNA, in your family history, this great American Christian religious figure of Walter Rauchin Bush.

How aware of that were you of him? How did you become aware of him growing up?
