'Common ground' among Christians at center of Swiss papal visit

Pope Francis’ visit to the headquarters of the World Council of Churches next month highlights efforts by churches to "walk, talk and work" together, according to the organization's secretary general, Olav Fyske Tveit. The head of the Geneva-based organization also tells Paula Dupraz-Dobias that the WCC has become a peacemaker involved in helping warring parties to sit down and talk. He recently returned from North Korea, where he met with local churches and authorities in what he calls the country’s "spring of peace."
