The pope also extended his greetings to the thousands of artists who had come to celebrate their Jubilee in Rome this weekend.

To facilitate his recovery, doctors have prescribed that he observe “total rest,” the Vatican press office announced.

The announcement came as Francis was in his bed in the Gemelli Hospital being treated for an infection of the respiratory tract. A Vatican spokesman said "the Holy Father passed a good night and slept well.”

On “Jesuitical” this week, Zac and Ashley chat with Simon Critchley, the Hans Jonas Professor of Philosophy at the New School for Social Research in New York, about his new book, 'Mysticism.'

Cancellations announced by the Vatican suggest the pope will be hospitalized for several days.

From both the Vatican and the pope, we have heard a consistent message: A.I. is a tool that is created by and shapes human culture. Thus far, however, we have not seen much in the way of specific recommendations. We believe that this is an important next step for Francis as he emerges as a leading global voice in conversations about A.I.
