Looking back through history we see certain figures who were not the Bishop of Rome who were the leaders of the Church all but formally.  St Paul, St Catherine of Siena, just for starters.  Maybe a century from now Card. Robert Sarah will be in that list.  There is a man who preaches with joy and love and leads as a servant.

Francis shrinks away from the Gospel (in a manner all too typical of an '80s Jesuit), is a heavy-handed authoritarian, let disorder (and bishops in the style of Weakland or Hubbard) resurge in the Church, and either cannot or will not answer simple dubia concerning his encyclical.  None of these are the behavior of a voice crying out in the wilderness.
