Through the years, following my baptism and conversion in the 90s....I was ever bewildered by the amount of literature on blood and 'fractions' - and changing medical directives etc.
I reasoned with myself, during the initial process in which blood is artificially removed from the living body, does it cease to be blood? No.
Surely, I reasoned, the abstaining of blood finds its moral and scriptural beginnings in the actual taking and donating of blood. An upholder of this doctrine would surely refuse any substance that initially involved the donating and taking of blood. It's that simple, because whatever you call the end 'blood fraction', blood was donated in order to produce it.
But anyway, the real issue is that a life isnt taken or snuffed out in order to sustain another humans life through the taking of blood. We don't kill a human to get their blood, in order to 'sustain' our own lives.
That, in anyone's book is repulsive.
Blood taken from a willing, voluntary and living being is a mere transfer of 'organ'.
A life is not lost or murdered.
This doctrine is another embarrassment to JWs and also a danger.
