TheDivingPreacher:
Sorry about the duh response. I am really not trying to do that at all, although of course from a Christian perspective those "writings" are just as relevent today as they were 2000 years ago.
...
Some background, to perhaps bridge the gap between 2000 years ago and today:
In the 1530s, the Spanish theologian Francisco de Vitoria wrote that a sick man could refuse food without risk of committing a mortal sin if he had no hope of survival. Another prominent Catholic theologian, Domingo Banez, built on Vitoria's premise in 1595 by establishing the guideline that "ordinary" means of medical treatment were obligatory, but "extraordinary" means -- methods that would cause great pain or burdens -- were not required. That position was further solidified in 1957 by Pope Pius XII, considered the modern architect of Catholic medical ethics, who told a group of anesthesiologists that they were not required to provide life-sustaining care unless there was a reasonable hope of recovery.
Pope John Paul II has said feeding tubes are "morally obligatory" for most patients in vegetative states, and high-ranking cardinals have followed up by referencing Schiavo, saying that removing her feeding tube could lead to legalized euthanasia.
Theologians disagree about whether the pope is altering Catholic tradition, but there is consensus across the ideological spectrum that the Vatican's position in the Schiavo case has given Roman Catholics a new calculus for end-of-life decision making.
If the Popes cannot agree, then arguing amongst ourselves about religious ethics, by less august religionists such as we here are, is going to be useless, as well as being irrelevant.
Irrelevant, because in America, it is courtroom judges who alone are empowered by American law to make life and death decisions in general. And they are sworn to look towards constitutional, statutory, and precendential law, rather than to any decrees of religious leaders.
I am hoping that any further debating based on religion will therefore abate.
