Based on the Pope's actions and words during the first days of his Papacy, this move does not come as a surprise. It is consistent with his desire to live simply and follows his actions in Buenos Aires where he preferred to live in an apartment rather than in the archbishop's house. Some had already joked he would sell the Apostolic Palace and move into an apartment in the nearby Borgo Pio.
Many may find this disconcerting, that the Pope does not want to live in the place where Popes have traditionally lived for centuries. I believe it is his decision and should not shatter anyone's faith. If our faith and trust in Jesus Christ depends on where the Pope lives, we have serious problems.
As I wrote a few days ago, I believe our new Pope is the Papal version of Blessed Mother Teresa of Calcutta. This is what the Church needs today in order to make uncomfortable a world (and a Church, especially in wealthy countries!) that has become too comfortable and complacent."
Amen to that, Pablo!
