As he did on Sunday, Francis participated in the retreat remotely from the Rome hospital where he is being treated. He could see and hear the Rev. Roberto Pasolini, preacher of the papal household, but the priests, bishops and cardinals gathered for the retreat in the Vatican auditorium could not see or hear him.

Pope Francis "had a quiet night, and is resting" as he continues to receive treatment for bilateral pneumonia, according to an update from the Holy See Press Office.

With Pope Francis entering his fourth week in hospital, those working in the Apostolic Palace are grappling with the continuing uncertainty over the pope’s health. The same is true for everyone in the Vatican.
