[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.

We have a pope [Francis] who's very popular among the Catholic faithful and non-Catholics, but there's no doubt he's going to continue to face resistance from conservatives inside the church.

Father Jude Nnorom also criticized his church leaders, saying the simple lifestyle followed by Pope Francis should challenge African bishops to ask themselves.

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.

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

[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.

One of the topics that [Pope Francis] wants to raise, according to many Vatican analysts, is given the shortage of - worldwide shortage of priests is the possibility of a married priesthood. But he needs more backing from his bishops right now.
