learntoswim,
At the risk of sounding confrontational, (I honestly don't intend it that way.) I've never been able to make heads or tales of this JW reasoning:
The difference in eating and transfusing blood is in my view nullified by taking a look at the reason why God said not to eat it. I believe this is very important to the issue. When you look at the commands God gave to the Jews, he on many occassions explained that the blood means the life, it is something he views sacred.
Unlike the JW's, the Jews understand that direct commands from God may be contravened only by other direct commands from God. In other words, human speculation on the unstated reasons behind command 'A' would, in and of itself, never justify setting aside command 'B'.
God has told us directly in plain and simple, black and white, clear and unambiguous terms that we are not to cause or be the cause of the loss of innocent human life. Yet when it comes to the life of a child, an aged parent, an adult of diminished responsibility or any other situation where you would be responsible for the life of another, adherence to the JW transfusion medicine taboo can easily result in the responsibility for the loss of life falling directly on your shoulders. (Witness children have died from things as mundane as falling off of a skateboard.)
This seems to me to be a clear case where command 'B' would be set aside based upon human speculation on the unstated reasons behind command 'A.'
e.g. God didn't want us to eat blood because he views all blood as sacred. Therefore we can assume that He wouldn't want blood to be transfused either.
It should be poured out on the ground, and not ingested. It is apparent to me from this that God was not just saying, don't eat it because I don't want it to go into your stomachs, rather the actual principle is he would hate for anyone to take in blood into their bodies.
I think you're equivocating here. Disparate acts are not rendered either physical or moral equivalents simply by referring to them with a term sufficiently generic to apply to both. There's a huge difference for example, between taking water into your digestive system (Your stomcach) versus taking water into your respiratory system (Your lungs) Although you could truthfully say that a drowning victim died from "Taking in" water, drinking and drowning are not physically equivalent acts in anything other than that which can be described with an extremely generic term such as this.
The same is true of moral equivalency. For example, the Law proscribed murder, but at the same time it provided for capital punishment for certain crimes. Why was this not contradictory? Because murder and capital punishment are not moral equivalents. And referring to them both by using the generic term, "Killing" doesn't change that fact.
If the consumption of blood and the transfusion of blood are equivalent acts either physically or morally (Or both) it would be because this equivalency can be clearly demonstrated in concrete terms, not because they can both be described with a generic term like, "Taking in." The latter is simply the fallacy of equivocation.
Transfusion medice must be positively shown to fall under the umbrella created by the specific commands against eating blood. Anything less than this and the clamaint has for all intents and purposes professed to know the mind of God by claiming to know what God was consciously thinking at the time He caused the command to be written even though that intent is nowhere expressed in the words He inspired to be written.
(I know that wasn't your intent.)
