This doctrine is close to my heart for many reasons, not the least of which is that it was the catalyst to me being able to think for myself. I spent a lot of time defending this doctrine. Even went to far as to argue that the "good health to you" closing of the apostolic decree was a sort of prescription from Luke! That Jehovah knew this would be "better" for us, and tipped his hat a bit to us with that phrase.
But after pouring in and out of various components, and understanding the policy I was met with 2 things that i could not shake.
1) If someone according to JW policy was to refuse something, and later that was changed (like organs), who was responsible for the blood of that person? Was the blood guilt communal?
2) Who was deciding what was approved and what was not, but more importantly, what was the CRITERIA they were using to make this decision on behalf of 8 Million JW's? ( nobody could answer the "criteria" part of this question)
I have been able to use these same 2 points to undo most arguments for blood. And yes TD is right......most of the time i just hear "I couldn't care less about the blood doctrine.......its like the resurrection doesn't even matter to you." Most JW's can't be bothered with the import of this, and in the end....Jehovah will resurrect you to pet lions, never die, and wear nursing scrubs over your smooth parts?
I had a weeks long conversation with a CO friend over this. Very thoughtful, and studious man whom I respect. In the end his arguments were that the FDS is chosen, so you have to listen to that direction, and that since growth has continued to occur.....Jehovah is still blessing the work! At that point, we respectfully bowed out of the conversation. I have not heard from him since.
