Why won’t Jehovah’s Witnesses accept blood transfusions, even when their lives are in jeopardy?
Mainly because their founder, Charles Taze Russell, scrambled to come up with a unique set of doctrines that would stand out from the pack. He didn’t seem to care which biblical teachings he embraced and which he rejected, so long as the resulting doctrinal pastiche would be exotic. Rejecting blood transfusions on “biblical” grounds is one of the WTS’ truly odd tenets. Witnesses cite two verses as bases for their position:
Besides being inconsistent by retaining this particular Old Covenant prohibition while ignoring others, such as circumcision (cf. Gn 17:2-14) and kosher dietary laws (cf. Dt 14:3-21), Witnesses misunderstand what these passages are talking about. In both Leviticus 7 and 17 the prohibition is against the eating of blood, not reception of blood through transfusions (a medical procedure which was developed only within the last century). Witnesses ignore the fact that in a single passage in Leviticus the Lord prohibits the eating of both blood and fat: “It shall be a perpetual statute throughout your generations, in all your dwelling places, that you eat neither fat nor blood” (3:17). Yet the Watchtower does not condemn the eating of fat, and no Jehovah’s Witness would feel any moral compunction against eating a bag of fried pork rinds or enjoying a nice, fatty cut of prime rib. This is a good example of the Watchtower’s selective “theology.”
