In reading an interview of a former professor of Pope Francis, Father Juan Carlos Scannone, to Mauro Castagnaro, I read a description of
Jorge Mario has three great qualities: he is a man of spirituality, and when he was my provincial I had the impression that he ruled based on spiritual discernment, at least with respect to me. He is austere, so that in Buenos Aires he traveled by subway or bus -- and often visited the poor neighborhoods, defending priests who worked there. He is determined, and therefore he will implement the necessary changes in the Church, but without causing a rupture.
Father Scannone continues to state his expectations of Pope Francis. You can read the interview at the blog Public Vigil.
