However, the fact is transfused blood is not usable as food or as nourishment but only as blood which may then “carry nourishment … to the tissues” (Taber’s Cyclopedic Medical Dictionary, Clayton L. Thomas, ed., 16th edition [Philadelphia, PA: F.A. Davis Company, 1989], page 223, under Blood). The transfused blood itself is not consumed as a “food,” the way it would be if it were eaten or drank through the mouth and then broken down like other foods through the digestion process. This could be, to use the Society's 1964 words quoted above, "feeding upon a God-given soul as contained in the blood." But when a person is starving to death a transfusion of blood does not provide nourishment for the body, that is, unless actual “food” or nourishment is next added to the body and then the transfused blood carries it “to the tissues” (Taber's, page 223).
That the "soul" is in the transfused blood according to the Bible does not change this in any way, that is, the "soul" part of the blood still does not provide nourishment or "life" to any person on its own when transfused with blood. Further, there is no evidence of the "soul" in the blood being consumed (= "feeding upon") in any way during a medical transfusion of blood: Transfused blood is used as blood by the recipient's body, not as a food or as nourishment of any kind. It is similar with organ transplants, which is what a blood transfusion is since the organs are not ‘eaten’ by the body once they have been transplanted, and neither do the transplanted organs serve as “food” or as “nourishment,” as I explained. Organs, including blood, have specific purposes and functions created and designed by God. Transfusing blood is one way for blood to continue to function according to its designed purpose, while eating blood or organs as "food" does not permit any of them to continue working in the body according to their intended purpose(s).
