This is what throws me. I would think that all those Christian followers would welcome her release to the next plain of existence; release from the physical bond that had imprisoned her for so long in a state that prevented her from experiencing anything about life. What you describe sounds more like Platonic rather than Christian thought. Christianity is an incarnate religion. The soul is not "imprisioned" in the body which is "released" upon death. Personhood includes both soul and body. Besides, a Christian would tell you that the separation of body and soul is only temporary. I think it's a mistake to base personhood on a certain level of brain activity. A person has a brain but a person is not a brain. Terri died in 2005. That is the official year of death, and any other interpretation is a grave presumption as to what it means to be alive. I feel like I'm rambling, but that's because I don't know how to adequitely explain beyond giving my thesis, which is: The reason people approve of the outcome of the Schiavo case and other forms of euthanasia is due to a fundamental misunderstanding of human personhood.
