[Pope Francis] lashed out against what he called malevolent resistance to his reforms.

[Pope Francis] most recent trip was to Sweden, where he commemorated the 500th anniversary of the Protestant Reformation. That had triggered one of the biggest splits in Christianity and decades of religious wars. He went so far as to praise Luther, who was once considered a heretic in the church, as a great reformer. So what he's been doing with other Christian churches is trying to heal past wounds and work together toward a shared view of their history.

Asked about Donald Trump, [Pope] Francis said a person who thinks only about building walls and not building bridges is not Christian, a remark you might remember that Trump described as disgraceful.

The Vatican has always had a core of diplomats for centuries. It has ambassadors in 180 countries and always played a kind of behind-the-scene role in many world issues.

A group of four cardinals wrote to [Pope] Francis accusing him of sowing confusion on important moral issues, and they asked for clarifications. He did not reply. And one of the signatories, the American Cardinal Raymond Burke, said if the pope does not clarify, he will proceed with what he called a formal correction of the pope after Christmas.

[Pope Francis] continued to focus on migrants. He visited the Greek island of Lesbos, which was the front line of the European migrant crisis. And a month later, he accepted a prestigious European Union prize, but he scolded Europe for its treatment of migrants. And in a speech echoing Martin Luther King, he said I have a dream of a Europe where being a migrant is not a crime. So, yeah, he showed he can be quite outspoken on political issues.

[Pope Francis] symbolically took the migrant south-north route to the United States by going to Cuidad Juarez on the border with Texas, and there he spoke of the human dignity of immigrants.
