"Your commentary is moot and assumes the Bible proscribes blood transfusions. We JW believe it does. The issue is whether or not JW belief is only interpretation subject to error. If it is, the grounds for JW ban on BT is Biblically uncertain."
The JW belief doesn't matter. "It's Moo." 😆 Lol... Sorry, trying to be punny...

It's what Jesus said that matters.
"Eating" blood doesn't just mean literally "eating". It can also mean "taking in".
John 6:53-56
"So Jesus said to them: “Most truly I say to you, unless you eat the flesh of the Son of man and drink his blood, you have no life in yourselves. Whoever feeds on my flesh and drinks my blood has everlasting life, and I will resurrect him on the last day; for my flesh is true food and my blood is true drink. Whoever feeds on my flesh and drinks my blood remains in union with me, and I in union with him."
When Jesus used the words "drink" and "eat" here he was not talking about literally "drinking" and "eating". He meant "taking in" his teachings and making them a part of ourselves.
Deuteronomy 12:23-25
"Just be firmly resolved not to eat the blood, because the blood is the life, and you must not eat the life with the flesh. You must not eat it. You should pour it out on the ground like water. You must not eat it, so that it may go well with you and your children after you, because you are doing what is right in Jehovah’s eyes."
Some people get all bent out of shape about taking in "genetic material" and thimerosal and formaldehyde in certain vaccines. Others are worried about getting an implanted microchip. Their consciences are uncomfortable putting things in their body that don't belong there.
It's good to train and listen to our conscience. But while the Bible doesn't specifically comment on whether or not putting those other objects in the body is right or wrong, it does say for sure that there is one "genetic material" that should never be taken into the body: blood.
John 6:56
"Whoever feeds on my flesh and drinks my blood remains in union with me, and I in union with him."
Jesus was saying that a person "taking in" his teachings and making those teachings part of themself is "in union" with him.
"Taking in" blood in any way (whether whole blood or fractions of blood) and making it a part of your body is becoming "in union" with someone else by means of their genetic material. God said not to do it. The only blood that is authorized for use for salvation is the blood of the Christ.
Leviticus 17:11
"For the life of the flesh is in the blood, and I myself have given it on the altar for you to make atonement for yourselves, because it is the blood that makes atonement by means of the life in it."
