Christendom and the world. Those in the world think that someday they will be able find the cure for the “sin gene.”
Jehovah Witnesses believe sin is in the blood. This is what the Watchtower teaches,
“The blood in any person is in reality the person himself. It contains all the peculiarities of the individual from whence it comes. This includes hereditary taints, disease susceptibilities, poisons due to personal living, eating and drinking habits . . . The poisons that produce the impulse to commit suicide, murder, or steal are in the blood.” (Watchtower 9/15/1961, page 564)
Watchtower is saying that such sins reside in physical blood. This is one of the reasons why they won’t allow blood transfusions. Sin does not reside in the blood, nor does righteousness reside in the blood, and any Scripture quoted is used as a smokescreen to enforce the Gnostic thinking.
The Bible does use terms like “innocent blood” and “righteous blood” but this is not talking about the properties of blood itself.
The innocent blood is speaking of one who was simply innocent from doing any crime, who are unjustly punished, and the righteous blood refers to those saints who were righteous, “righteous Abel unto the blood of Zacharias.”
Here are two quotes some may use to try and prove blood has moral properties.
“For he did put his life in his hand, and slew the Philistine, and the LORD wrought a great salvation for all Israel: thou sawest it, and didst rejoice: wherefore then wilt thou sin against innocent blood, to slay David without a cause?” -1 Sam 19:5
“That upon you may come all the righteous blood shed upon the earth, from the blood of righteous Abel unto the blood of Zacharias son of Barachias, whom ye slew between the temple and the altar.” -Matt. 23:35
Note it is obvious that it’s not referring to moral properties in the blood, for physical blood has no moral properties. A person who is innocent is one who is free from guilt; not having done wrong or violated any law. In Matthew Jesus talks about those righteous people from Abel right onto Zacharias! Jesus was not referring to these people in the sense of their blood having moral property (for it doesn’t!), but of the people themselves living a righteous life, innocent, and whose blood was shed, from Abel to unto the blood of Zacharias.
