According to Jerry Bergman, author of BLOOD TRANSFUSIONS: A HISTORY AND EVALUATION OF THE RELIGIOUS, BIBLICAL, AND MEDICAL OBJECTIONS, 1994, p. 5:
"The blood issue has brought witnesses more publicity than any other issue in the last twenty years."
"The ban on blood transfusions was an effort to solidify the Knorr administration." [Knorr initially objected to the weird scriptural interpretation justifying the abstaining from blood; he understood the scriptures to be in reference to animal blood only. Nevertheless, he went along with the ban.]
"Key Watchtower officers held a view of distrust toward the medical profession."
"Some high level Watchtower official naively reasoned that, if eating blood was wrong, blood transfusions were also wrong because they are 'intravenous' feeding as opposed to extravenous feeding, or normal eating."
While Rutherford swallowed some irrational rantings by Franz and Woodworth over the beginnings of the blood issue, he would not allow publication of FWF's "special knowledge" as "new light" in THE WATCHTOWER. The two mischief makers kept things stirred up and began convincing others, including Knorr. The author was told that now that "King Saul" [FWF] is dead, the leadership would like blood transfusions to be a matter of conscience and lay the blame for all the suffering at the feet of Franz and Woodworth.
Does tacit approval on the part of the Governing Body constitute blood-guilt?
