By Philip Pullella VATICAN CITY (Reuters) – Pope Francis, who has penned weighty encyclicals and decrees, has taken a stab at the simpler side of his job with a book for children to answer such questions as “What did God do before the world was made?” That question was put to him by 8-year-old Ryan K., from Canada. The book, called “Dear Pope Francis,” was a brainchild of Father Antonio Spadaro, a priest and editor of the Italian Jesuit journal Civilta Cattolica who was the first person to interview Francis after his election in 2013. Spadaro brought the pope the 31 drawings and questions by children from around the world and Francis dictated his responses in simple language.
