Where Is the Pope's Encyclical on Christian Persecution?
It's noteworthy that Francis didn't merely make a passing comment on global warming during this or that sermon, but that he issued a papal encyclical on the matter. Encyclicals are much more formal and significant than remarks made during mass. They are letters written by a pope and sent to bishops all around the world. In turn, the bishops are meant to disseminate the encyclical's ideas to all the priests and churches in their jurisdiction, so that the pope's teaching reaches every church-attending Catholic.
