The Pope will apparently follow the traditional Sunday Angelus prayer from his room at Rome’s Gemelli hospital, where he is recovering from a throat operation.
In a statement, the Vatican said the Pope would join the service but it indicated John Paul II would not appear at his window, as he did during his last hospital stay.
Vatican spokesman Joaquin Navarro-Valls visited the 84-year-old Pontiff this morning.
In the hospital chapel, round-the-clock prayers are being said for the Pope.
He has been advised not to speak for several days following Thursday’s tracheotomy operation to help him breathe, and is apparently communicating by writing.
The Vatican’s deputy Secretary of State will deliver a blessing tomorrow from the steps of St Peter’s Basilica on the Pope’s behalf.
Every detail of John Paul’s latest illness is being followed closely by both local and international media.
Any appearance he does manage to make tomorrow will, no doubt, be greeted with delight by Catholics around the world.
