Pope Francis has been called "the revolutionary Pope." Before he became Pope Francis, he was a Jesuit Cardinal in Argentina named Jorge Mario Bergoglio, the son of a rail worker. Moments after his election, he made history by taking on the name Francis, after Saint Francis of Assisi, the leader of a rival order known to have shunned wealth to live in poverty.

Pope Francis' June 2015 encyclical is called "Praised Be," a title based on an ancient song attributed to St. Francis. Most papal encyclicals are addressed only to Roman Catholics, but this one is addressed to the world. And while its main focus is considered to be climate change, its 184 pages cover much more than that. Among other sweeping reforms, it calls for a radical overhaul of the banking system. It states in Section IV:

Today, in view of the common good, there is urgent need for politics and economics to enter into a frank dialogue in the service of life, especially human life.
