We are compelled to express our deep concern over the reinstatement of controversial Bishop Richard Williamson to the Apostolic College. It is our view – one shared by a vast swath of world opinion – that the inexplicable reinstatement of this divisive figure threatens to directly undermine the moral authority of our faith by associating the Holy See with odious, inflammatory distortions of a forensically documented historical tragedy. This has provoked a wholly unnecessary revival of painful divisions within our Catholic community, and has renewed our estrangement from other people of faith with whom we share so many core values, most particularly our Jewish brothers and sisters.
