Pope John Paul II has developed a high fever and is being treated at the Vatican for a urinary tract infection. Wednesday the Vatican acknowledged the Pope was being given nutrition through a feeding tube.
There are confirmed reports that the Pope has been given Sacrament of the Anointing of the Sick, also known as "last rites." However, that sacrament can be administered not only to those who are dying, but also for those with serious illness.
