Hi Cofty
More than a year ago before I started my fade, I told the elders that I don't agree with the WT view on blood.
I explained them in writing in great detail why I would allow for myself and my son a blood transfusion when alternatives won't work.
I spent a few hours discussing with 2 elders exactly about your reasoning.
The only thing they could do is to scratch their heads and direct me to a "Questions from readers" article in WT 15.04.83 dealing about that. There it is said that the situation described in Lev. 17:15 is only if an israelite erred "inadvertently", and ate a dead animal unbled.
When reading the context how can it possibly be, that you eat "inadvertently" an already dead animal or one torn by wild beasts? The elders had to admit, that this is not the case in Lev. 17:15.
But of course they can't agree with a view that goes contrary to what the org is saying.
I showed this reasoning to some close jw friends and also my parents.
The reaction is, that they really start to think and also to question the blood doctrine.
They understand the reasons why I would allow blood. They said, maybe you are right and the org. is maybe wrong with it. But we have to obey and trust the FDS.
Some say, "I can't say how I am going to react in a life and death situation."
But I agree with you cofty, that these reasonings you mention are the best possible way to make a jw reconsider the blood doctrine. These are great biblical arguments that JW don't know.
And by the way. I am sure that the bible is not god's word. It was a long and sometimes painful journey for me to come to that conclusion.
When talking to a JW about any topic though, you have to reason in a way, as if the bible is god's word.
