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.

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.

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