The government -- which would have no authority unless it was given from above -- apparently decided Michael Schiavo has the power to speak on behalf of his disabled spouse. That he should speak for her seems reasonable in light of the fact that "they are no longer two, but one flesh. What therefore God has joined together, let no man separate."
Jesus "told" me (and you) that whatever you do to the least of His brethren you do to Him.
It appears that a husband is carrying out his wife's wishes. Or, was her union with him against her will? More than that, was it against God's will? Are her (alleged) suffering and (apparently) impending death against God's will?
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.
Indeed, some would insist that I should count you out. But, instead, I'm hoping you're not totally opposed to clear thinking.
Umm, there've been governments throughout history up to and including the present day that have wielded (and do wield) plenty of authority, but which I can pretty well guarantee weren't given it from anywhere above. Maybe you have a different interpretation of history, but I'm pretty sure yours is in the minority.
