Pope Francis on Sunday wrapped up a weekend trip to Belgium, where he faced some of the strongest criticism yet levied during one of his foreign trips. The 87-year-old pontiff was pressed by high-profile figures at three of the five major events on his three-day visit in unusual and sometimes fierce language for a papal trip.

On Saturday, Pope Francis acknowledged that the abuse scandal had created "atrocious suffering and wounds," and undermined the faith.

Francis was urged in Belgium by both King Philippe and Prime Minister Alexander De Croo to do more to help abuse survivors in unusually forceful language for a papal foreign trip, always a carefully choreographed event.
