Do you think the speech was written by Cardinal Mueller?
When he speaks spontaneoulsy, however, the real Francis appears, e.g. daily Mass homilies in Casa Santa Marta and airborne press conferences. That's usually when things go off the rails, big time. So it's interesting that he now appears to be ditching more of the pre-prepared speeches in favor of his own improvised, spur-of-the-moment thoughts. A natural progression for El Lider Maximo.
