The government is not even on the horizon. It is not a part of the equation nor even in the picture. My duties to the sick and dying do not derive from the government nor have any relevance to the government unless it attempts to impede me from performing them as it clearly is in the Schiavo case.
Did He tell you He wouldn't want to live like that?
Jesus "told" me (and you) that whatever you do to the least of His brethren you do to Him.
You want to starve and dehydrate the one who died on the cross for you? One who is helpless and who even resembles the dying Jesus in his Passion?
Count me out.
