As both a pacifist and someone who works on a daily basis with people who have disabilities, I have a unique, if not strange, perspective on this issue. But both of those aspects of my life stem from my commitment to Christian discipleship and therefore my position on this issue is as much a result of my calling to follow Christ, as it is related to my personal beliefs and experiences.

There are two sides emerging on this debate over Terry Schiavo. There are those who say she has a "right to life" and others who say she has a "right to die." My goal here is to show that neither of those positions are consistent with Christian ethics and that we only do violence to the world to put things in such terms.
During Holy Week I am reminded of Jesus' refusal to fight for his life. He instead viewed it as belonging to God, meant for the purposes of God. When we begin viewing life as a right I think that is where we begin to get into trouble. Our lives belong to the God who created us for himself, and Christians have made such a confession in their baptisms, where we die and are born new in a life devoted to God. Coupled with our hope in the Resurrection, we really cannot be afraid of death, since we have already died, and the life we do have is now life in Christ, so that if we die, we may live in Him. Echoing Jesus' final words, what does it mean for us then to "unto God commend our bodies?"
Terry is not terminally ill any more than you or I, in that we are all going to die whether we want to or not. Certain functions of her body are impaired, yes, but she is not "dying" in the classical sense, which usually brings up the euthanasia debate. With assisted-feeding Terry would live out the natural length of her life. Her feeding tube is merely there to aid in her eating/drinking, much like the dependency an infant has on being fed by others. Without this tube Terry will die of starvation and dehydration, and regardless of her persistent vegitative state, this is a pretty awful way to die. Terry is not being artificially kept alive by some large, robotic apparatus that maintains otherwise failed internal functions. She is merely being fed. Each weekday I work with people who have difficulty eating--from not being able to use their hands, to having difficulty chewing and swallowing, I am there to assist people who need help caring for themselves. I must admit that they are more "there" mentally than Terry is (given her doctors' diagnoses), but I mean to show that the ability to eat is no measure of someone's ability to live a meaningful life.
Inasmuch as we need to recognize that life is a gift from God and we have no right to it, we also need to recognize that we do not have a right to take it or end it. The same is true of Terry and her very own life. Much has been made by her husband of a wish by Terry before her accident that she not be kept alive in such a state. But she has no such right to decide when she lives and when she dies, although this by no means is to say anything about the laying down of one's life in obedience to Christ. That choice, if really made, was in fact a suicidal claim of ownership over her life. Now, even her husbands insistence that we "do what's right for Terry" or "what Terry would have wanted" reinforces the idea that we are all autonomous individuals with a right to live/die. The loss of her autonomy only makes her seem more desperately in need of a relief from the suffering since that autonomy is what many believe makes life worth living.
On the other hand, the keep-Terry-alive camp uses the same rights language to fight for Terry's life, and many discredit her husband's reports that she ever wished anything than to be kept alive. In both cases, the emphasis is primarily put on what Terry would want. If you look at my previous post you will see that our lives are in the hands of the community as much as ours, and that this is not a matter of "personal wishes." The community that is the Church of Christ also happens to be the community that holds our lives and offers our life to God on our behalf (much like the congregation's role in baptism).
I do understand what the parents are feeling though: hope that she is indeed "alive" (in a non-bioligical sense). Similar to the way Christian parents hope life has begun in the womb (the reason the Catholic church opposes artifical birth control), we rightfully hope for the flourishing of life in all people. Yes we were reminded on Ash Wednesday, from dust we came, to dust we shall return. Death is seldom something anyone has a hold on, and we in the Church have been trained through various practices to respond to death in a way that is fitting. But in this case, Terry is not dying and we do not need to "let her go." Regardless of her brain activity, or of her wishes then or now, I can only pray in hope that the gift of life she received is one that we can nurture and nourish (even through a feeding tube). And in caring for life as a gift, we can better come to terms with death.
That said, I am not sure that court action and legislative maneuvering are the way to go. To fight for Teri on the grounds of her right to life only legitimizes the language that makes life a possession to be done with as we please, rather than used for the fullness of the communal life lived unto God. The Vatican issued a statement to its church members instructing them what the position of the Catholic church was on this case involving one of their baptized members. We cannot expect much from a world that treasures individual autonomy and inalienable "rights," but the Church is far better equipped to deal with matters of life and death. Hopefully from this case the we will learn how to better confront such issues so that we always carefully and thankfully receive the gift of life without straying into an idolatry of it. Also, I hope we can learn the difference in language that makes "rights" inconsequential, and thus removes our need to fight for them in courts, in chambers, or in hospices in Florida, but instead act as a Church Body, at the bedside, feeding those who cannot feed themselves, and holding the hands of those whose time has come.
