Belgium’s prime minister blasted Pope Francis for the Catholic Church’s horrific legacy of clerical sex abuse and cover-ups here, demanding “concrete steps” to come clean with the past and put victims’ interests ahead those of the institution in a blistering welcome at the start of Francis’ visit on Friday.

During a trip to Luxembourg and Belgium, Francis will spend an hour meeting with 15 people who were abused by Roman Catholic clergy. Survivors say it is not enough.

The king also had strong words for the pope, demanding the church work ‘incessantly’ to atone for crimes and help victims heal after decades of revelations.
