Pope Francis greets Pope Emeritus Benedict XVI prior to the start of a meeting with elderly faithful in St. Peter's Square at the Vatican, on Sept. 28, 2014. Emeritus Pope Benedict XVI turned 95 this past weekend, a significant milestone on its own but even more given he has now been a retired pope longer than he was a reigning one. To mark the occasion, a new book published Thursday, April 21 sets out to examine the current state of Vatican affairs not so much through the lens of Pope Francis’ nine-year papacy, but via Benedict’s nine-year retirement.
