Throughout this legal battle, supporters of reconnecting Terri Schiavo's feeding tube have used religious faith as the justification for their insistence that Ms. Schiavo should be allowed to keep living. They cite biblical authority and Christian doctrine to claim that God is on the side of life, and that Christians in particular are obligated to stand up for the sanctity of life. Yet, the underpinnings of these people's certainty that Terri Schiavo's condition could improve comes from science, not religion. And religious belief -- Christian religious belief in particular -- does not lead inevitably to the conclusion that keeping Terri Schiavo alive at all costs, regardless of her awareness or her ability to think, feel, or communicate, is the only way to value life.
