EXCLUSIVE — Bishop Robert Barron believes that for “free exercise of religion” to thrive, the United States must continuously affirm and bolster its explicitly Christian identity.

Barron, the prelate of the Diocese of Winona-Rochester, is delivering an address at President Donald Trump’s Rededicate 250 event on Sunday. The event, hosted on the National Mall, is characterized as a “national jubilee of prayer, praise, and thanksgiving” that celebrates the American ideal of “one nation under God” and the “role that religion has played in the American experiment.”
