Pope Francis has been known for years as a humble man who denied himself the luxuries that previous Buenos Aires cardinals enjoyed.
Known previously as Jorge Bergoglio, the 76-year-old often rode the bus to work, cooked his own meals and regularly visited the slums that ring Argentina's capital. He considers social outreach, rather than doctrinal battles, to be the essential business of the church.
He has in the past accused fellow church leaders of hypocrisy and forgetting that Jesus Christ bathed lepers and ate with prostitutes.
In his first appearance in St. Peter's Square as the new pope today, Francis wore a simple white robe.
