(Luke 6:6-11) 6 On another sabbath he entered the synagogue and began teaching. And a man was there whose right hand was withered. 7 The scribes and the Pharisees were now watching Jesus closely to see whether he would cure on the Sabbath, in order to find some way to accuse him. 8 He, however, knew their reasoning, so he said to the man with the withered hand: “Get up and stand in the center.” And he rose and stood there. 9 Then Jesus said to them: “I ask you men, Is it lawful on the Sabbath to do good or to do harm, to save a life or to destroy it?” 10 After looking around at them all, he said to the man: “Stretch out your hand.” He did so, and his hand was restored. 11 But they flew into a senseless rage, and they began to talk over with one another what they might do to Jesus.
So with regards to the blood policy. How does the leadership of JW's act? Like Jesus or like the Pharisees? Because, remember, Jesus asked them if it was lawful to save a life on the Sabbath, thus breaking the law and subject to getting stoned to death. Then Jesus answered that question for them by healing the person, he said, "stretch out your hand" and healed him.
Notice that in Mark 3:5, Jesus said that they had no sensibility in their hearts as regards to this:
Now the leadership, the faithful slave will quote from Acts 15:20,29 to abstain from blood. But, if someone ate the meat with the blood there was no stated punishment for it, just a reminder:
(1 Samuel 14:31-35) 31 On that day they kept striking down the Phi·lisʹtines from Michʹmash to Aiʹja·lon, and the people became very tired. 32 So the people began rushing greedily at the spoil, and they took sheep and cattle and calves and slaughtered them on the ground, and they ate the meat along with the blood. 33 So it was reported to Saul: “Look! The people are sinning against Jehovah by eating meat with the blood.” At this he said: “You have acted faithlessly. Roll a large stone to me immediately.” 34 Saul then said: “Spread out among the people and say to them, ‘Each of you must bring his bull and his sheep and slaughter them here and then eat them. Do not sin against Jehovah by eating meat with the blood.’” So each of them brought his bull with him that night and slaughtered it there. 35 And Saul built an altar to Jehovah. This was the first altar he built to Jehovah.
Remember that when someone was observed breaking the Sabbath, they reported it to Moses and they didn't do anything right away. But then Jehovah said to put him to death. Notice that here, when it was reported to Saul, Jehovah did not say anything to them, no death, no punishment, just that they should not have done so, and he provided to them a slaughter. Then they built an alter, and nothing else is said as regards this in the Bible.
So why is it a disfellowshipping offense to take a blood transfusion when there is no precedent in the Bible for it?
