Mary - another excellent point I've never thought of. Without even getting into the grammar of it all as TD presents so awesomely, the beauty is the simplicity.
If this really was what God wanted to be the end-all communication of his view on blood, then it is as simple as you put, and not as complicated as JWs make it - and definitely not as convoluted as even DJ re-interprets the WTs very policy, making it worse than the Watchtower actually does.
Bible allows for the equal interpretation of two things: 1) Blood is sacred to God; 2) Life is sacred to God.
If blood is used for it's intended purpose, to preserve life which is sacred - then God would actually look upon this as loving, as Chirstian. Which is why even the early Watchtower writers (pre 1944) commended those who donated blood. It took a crazy wacko health freak to twist scriptures to condemn it - and a power hungry control freak to enforce it. The rest is history. Except now it's okay to take parts of donated human blood, even cow blood, to save life - but not other parts.
WT says 'It's okay for a mother to give her white blood cells while breast feeding, but not if her child is sick and needs them to fight off a disease. The child should die instead, even though that same child fed on those same white blood cells'
WT says 'It's God's design that identical twins transfuse blood to one another in the womb - so that's ok. But those same twins, once out of the womb, would not be able to transfuse blood to one another in the event of a life threatening illness. God hates that, even though he ok'd it previously in their lives. He says it is not a conscience matter. They will die at armageddon or go straight to gehenna for doing what I had them do earlier. But now, I wouldn't break my own laws on blood - so when certain fractions pass through the placenta - that is to tell you that fractions are a conscience matter.'
Yep - the WT's god is perfectly logical. As outlaw says - the WT has been telling Jehovah what to do well into 3 centuries now - but he can never seem to get it right.
The Watchtower would have disfellowshipped Jehovah long ago for his continued disobedience to their blood policy.
