VATICAN CITY – Pope Benedict gave Australia its first saint yesterday, a 19th century “whistleblower” nun who activists say should be the patron of victims of sexual abuse by priests because she was punished for exposing it.

At a solemn ceremony in St. Peter’s Square, the pope canonized Mother Mary MacKillop as well as five other church figures from Poland, Canada, Spain, and Italy who lived in the 15th to 20th centuries.
