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.

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.

The Pope also beatified Carmelite Sister Ana de Jesús, a spiritual daughter of St. Teresa of Ávila and a friend to St. John of the Cross.The beatification Mass was Francis’ last stop at the end of nearly three days in Belgium.
