Regarding the sanctity of life concerning end of life decisions, I will point out that the Church recognizes that medical technology has reached the point of Frankenstein whereby machines can continue a persons vital signs, in the absence of all other signs of human life and consciousness; and with the knowledge that natural life and consciousness are NO LONGER attainable for this person. In such cases the Church does differentiate between ordinary and extraordinary means in preserving life. Ordinary means is standard routine treatment that promotes comfort and dignity to the patient and includes pain meds to relieve suffering even if it hastens death - we are not in the business of suffering! That said, withholding ordinary means at this stage is euthanasia and is not morally acceptable. Extraordinary means, such as described earlier (kept "alive" by machines with no chance of recovery), attempts to thawt God's will by prolonging natural death. It is reasonable in such cases to withhold extraordinary means and to let natural death take its course. Each case is different, and prayerful consideration and consultation with trusted clergy is important.
