With stops in the nation's capital, the Big Apple and the City of Brotherly Love, Pope Francis made lots of political waves on his U.S. visit.
In his address to Congress, the pontiff asked the country's leaders to help solve the plight of climate change, to fight poverty and to embrace millions of undocumented immigrants.
"He's not a policymaker or an economist, but he can say what is working and what isn't working," says Thomas Reese, a senior analyst for the National Catholic Reporter, in an interview with CNBC. "He's hoping to get politicians to work together, to make sure the economy is working for all."
According to the Pew Research Center, the United States has the fourth-largest Catholic-faith population in the world, with more than 75 million followers filling church pews.
Reese said the pope came to America as a pastor to preach compassion, and as a prophet to provoke the most powerful nation in the world to do more good with its wealth. His remarks also urged the world's largest economy to be more welcoming of immigrants and refugees.
