I read this as part of my preparations for a trip to Italy. It is an excellent biography of an exceptional person. This is a revised edition which includes an extensive discussion of the Pope's successes and failures as Pope. The revised edition also includes additional research regarding what happened during Argentina's "dirty war."
Perhaps the most interesting thing about Pope Francis is how he has changed over time. In this respect, the book's opening quote sets the tone perfectly: "In a higher world it is otherwise, but here below to live is to change, and to be perfect is to have changed often."--John Henry Cardinal Newman
Early on, the book includes a scathing quote from a senior Jesuit who was asked to comment when Francis became Pope [regarding his tenure with the Jesuits]: "It was an absurd situation. He is well-trained and very capable, but is surrounded by this personality cult which is extremely divisive. He has an aura of spirituality which he uses to obtain power. It will be a catastrophe for the Church to have someone like him in the Apostolic See. . . "
Pope Francis rose to power within the Jesuits in his mid-30s during a terrible time in which the Church (and the CIA) were complicit in the torture and "disappearing" of tens of thousands of people. With respect to Pope Francis' role in this, the book makes clear that he had inside sources who tipped him off and thus he was able to help some people within the church who would have been targeted. On the other hand, he is accused of allowing the arrest of two Jesuits who disobeyed his orders. What actually happened seems unclear, although I did not get the impression that the Pope had entirely clean hands. In addition to this particular incident, the Pope was generally seen as dour and autocratic during his time with the Jesuits.
As a result of his troubled tenure, the Pope found himself in exile in Cordoba--essentially washed-up by age 50. Interestingly, during this period the Pope seems to have undergone a profound transformation. He became genuinely humble. The book notes that his critics don't really buy this transformation (the books quotes the Yiddish proverb that "too humble is half proud"), but I tend to think the change is largely genuine. When Pope Francis describes himself as a sinner, I think he means it. He knows he has made terrible mistakes and counts himself among those in need of mercy.
After Cordoba, the Pope became the "Bishop of the Slums," which is a persona that is a lot closer to what people think of when they think of the Pope as he is now.
The second part of the book covers the Pope's tenure as Pope. The book acknowledges what is pretty obvious--the Pope works hard at cultivating his image. In fact, the book starts out with an anecdote that sums this up nicely: the pope's bag was on a plane, but he had it taken off the plane so that he could be seen by reporters carrying his own bag onto the plane. Despite the obvious stagecraft, simple living is one virtue (unlike humility) that seems to be part of the Pope's essential personality.
Efforts to clean up the Vatican bank, diversify Church leadership in terms of both ideology and geography, and open up the Church in a pragmatic way seem to be some of the Pope's successes. Of course, he has achieved whatever success he has because, despite his avuncular image, he is no fool and he will move against those who challenge him. The incident with the individuals who set up the Kim Davis meeting demonstrates this well.
Two areas where the Pope has been something of a disappointment are the sex abuse scandals and the role of women. Even here, the Pope seems capable of introspection and taking advice. It is clear that he simply does not have a good grasp of modern, Western women. This makes sense in terms of his life experience, which has been as a sheltered man living in a male-dominated society. I like the stories of the Swedish Ambassador speaking truth to the Pope on this issue--telling him that idealized essentialism of women as "nice" isn't helpful, and I like that she gave him a copy of Nicholas Kristof's book (which he may have been aware of). With regard to the sex abuse scandal, it seems like the Pope's natural inclination is not to react as forcefully as he should. Here again, he seems capable, at least to a certain extent, of taking advice--in particular, from Cardinal O'Malley, who had some first-hand experience with dealing with this difficult issue.
In sum, although this is a longish, dense book, I would highly recommend it to Catholics, lapsed Catholics like me, or anyone who is interested in biographies of world leaders.
