Earlier this year, Pew Research published the results of a study on religious diversity around the world. While the U.S. didn’t even break the top 10 for most religiously diverse when all nations studied were taken into account, it ranked #1 in religious diversity out of the most populous countries.

The United States certainly has a Christian tilt and a sizable population of nones. But, go to any major U.S. city and you’ll spot kippahs, hijabs, turbans, and houses of worship for every major belief system on the planet.

Despite the American ability to live alongside people who believe vastly different things than us, the U.S. has a horrid past with religious oppression—think of the KKK’s treatment of Jewish people or the wipeout of indigenous people and their forced conversion to Christianity or the attacks on Muslims and Sikhs directly following 9/11.

And while many prejudices take decades to extract the mainstream, a quick study of our history reveals that there is a clear pattern of America’s ability to eventually accept religious differences.

Over a century ago, the Catholics pouring in from, first, Ireland and, later, Italy, were near the bottom of the social hierarchy—pushed down by the majority protestant community who had been there much longer. Today, 6 of our 9 Supreme Court Justices are Catholic—only 2 are protestants, and one is Jewish. Pathways to success at the highest level are available to all in the U.S., even to those who, not very long ago, were seen as inferior.

The U.S. has a long way to go in terms of equality and in the acceptance of all religions. But, if history repeats itself, it seems possible that even the faiths that are most discriminated against today, could also find great success here.

The United States had its 250th birthday last week. And, in the last few episodes we have tried to understand the role of Christianity in America’s founding. But what kinds of Christians were the first Americans? And what role did Catholics, Jews and Atheists play in the Revolution? Were there Muslims or Hindus on U.S. soil in 1776?

To answer all of these questions and better understand the nature of religion at the time of America’s founding I spoke with Katherine Carté. Carté is a History Professor at Southern Methodist University and wrote the book “Religion in The American Revolution: An Imperial History.”
