Pope Francis came into the Vatican with a mandate to change the way its bureaucracy functions (or disfunctions), in the wake of scandals, leaks and power struggles that have embarrassed the church. It seems to me that he’s taking that task seriously, by laying the spiritual groundwork for change.
He’s approaching the various Vatican environments not so much as the new boss, but as the new pastor.
I think that’s one big reason why he’s decided to continue to live in the Domus Sanctae Marthae, the Vatican guest house, instead of moving into the formal papal apartment. In the Domus, he’s a few steps away from St. Peter’s, as well as the Vatican City governor’s office, and his morning liturgies are accessible to Vatican employees.
In the Apostolic Palace, the pope would have been surrounded by Secretariat of State offices and the usual filters. In effect, the Domus provides a much better pastoral base for evangelizing the Vatican.
