The Bishop of the Madison Diocese is clarifying the church's position on living wills.More here.
Bishop Robert Morlino says he needed to do so because of the debate that erupted over the Terry Schiavo case. "According to the church's doctrine, if a living will gets in the way of medical procedures that could prevent death, even if a person is permanently unconscious, it is a mortal sin."
A previous post covered some of the differences between a "living will" and a "will to live".

I had neglected to link to Bishop Morlino's articles where he discusses this matter.
The first article is here, and the current article, "Medical treatment:Make decisions based on Catholic teaching", is here.
