Few politicos at the National Prayer Breakfast were shocked when President Donald Trump brandished copies of The Washington Post and USA Today to celebrate their "ACQUITTED" headlines.
But it was a Harvard University professor who did something even more provocative -- quoting strong words from Jesus of Nazareth -- during an event known for its meek Godtalk and vague calls for unity.
America's "biggest crisis," said Arthur Brooks of the Kennedy School of Government, is a culture of contempt that is "tearing our society apart."
"I want to turn to the words of the ultimate original thinker, history's greatest social entrepreneur, and as a Catholic, my personal Lord and Savior, Jesus," said Brooks, author of books such as "The Conservative Heart" and "Love Your Enemies." He is the former leader of the American Enterprise Institute, a conservative think tank.
The key passage for this era, he said, is found in Gospel of Saint Matthew, chapter 5, verses 43-45: "You have heard that it was said, 'Love your neighbor and hate your enemy.' But I tell you, love your enemies and pray for those who persecute you, that you may be children of your Father in heaven."
Brooks added: "Love your enemies! Now that is thinking differently. It changed the world starting 2,000 years ago, and it is as subversive and counterintuitive today as it was then. But the devil's in the details. How do we do it in a country and world roiled by political hatred and differences that we can't seem to bridge?"
Trump declined to take part when Brooks challenged prayer-breakfast participants to raise their hand if they loved someone who disagreed with them about politics.
As the next speaker, the president responded to Brook's remarks with words that unleashed a week of online debate among conservative religious believers -- early Trump supporters and reluctant Trump supporters alike -- who have debated the degree to which they can embrace his take-no-prisoners approach to national leadership.
Addressing Brooks, Trump said: "Arthur, I don't know if I agree with you."
