Emeritus Pope Benedict XVI commemorated his 93rd birthday with morning Mass, Bavarian folk songs and congratulatory phone calls.

This week on “Inside the Vatican,” Vatican correspondent Gerard O’Connell and producer Colleen Dulle explain why Archbishop Georg Gänswein has been missing from public events in recent weeks.

The Vatican sought Wednesday to explain the absence of a key member of Pope Francis' protocol team following the scandal over a book on priestly celibacy co-written by Emeritus Pope Benedict XVI.

Published in French in mid-January, the 148-page book -- "From the Depths of Our Hearts" -- will be released in English by Ignatius Press in late February.

This week on “Inside the Vatican,” the hosts dedicate the entire episode to the questions surrounding the new book From the Depths of Our Hearts.

Pope Emeritus Benedict XVI did not co-author the book ‘From the Depths of Our Hearts’ with Cardinal Robert Sarah and asked to have his name removed as co-author, according to Archbishop Georg Gänswein.
