[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] 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.

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.

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.

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

One footnote says that divorced and remarried faithful, who are not recognized by the Catholic Church because it upholds the indissolubility of marriage, might in some particular cases have access to the sacraments.

[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.
