I'm not going to answer the question, further, I am even MORE confused after consulting my 1/8/85 Awake on the subject.
It relates the tale of a British DO's wife who suffered from kidney shut down and was forced to start dialysis.
The procedure is explained in complete detail, and leaves no doubt that her blood is removed from her body and cleansed by the machine. The only scripture I can think of that applies here is Deut? which calls for blood to be "poured on the ground" after leaving the body.
An accompanying photo shows her next to the machine, an early model, which is just a huge Rube Goldberg contraption. There is no way they could possibly claim it is "part of her body" or that the blood remains in her veins. The article quotes scripture from Gen. 9:4 and Acts 15:29 (Acts so we cannot claim it's an OT demand I guess?) but NO mention of the command that "blood must be poured on the ground" after it leaves the body.
What a surprises that the WT would so carelessly "forget" scripture that is used every Sunday in every KH in the world to substantiate it's beliefs. In this case however, even Dubs might be able to add 2+2 and realize that the blood is leaving the woman's veins in the foto.
I'd LOVE more WT magazine references on this subject as it is a fascinating rejection of basic JW doctrine spun to become acceptable.
