The new Roman Catholic Pontiff shared his 77th birthday today with homeless people, one of whom brought his dog inside the Vatican. It was a visual example of Pope Francis' informality and modest lifestyle, in contrast to what he has called the "idolatry of money." In a recent statement he said, "It is vital that government leaders and financial leaders take heed and broaden their horizons, working to ensure that all citizens have dignified work, education and healthcare." This weekend, he denied right-wing accusations that he's a Marxist, while defending his criticism of capitalism and his focus on serving the poor. Is one of the world's most influential leaders pitting his church against the free market? Is he inserting religion into the realm of politics, or emphasizing the teachings of Jesus Christ, who warned against trying to serve both God and money?
