SANTIAGO, Chile – Pope Francis dove head first into the sex abuse scandal that has devastated the Catholic Church’s credibility in Chile, apologizing Tuesday for the “irreparable damage” to victims, but also acknowledging the “pain” of priests who have been held collectively responsible for the crimes of a few. Francis’ words were delivered amid unprecedented opposition to his visit: Three more churches were torched overnight, including one burned to the ground in the southern Araucania region where Francis celebrates Mass on Wednesday.
