It was recently brought up that in modern medical science that a woman does not supply blood to her baby just the feeding…..and only the man supplies blood. When Jesus was born he would not have had the blood of man according to one preacher. If the mother gives blood to its baby then the baby would have sinful blood from the mother’s side. So if the Father in Heaven supplied the blood and only the mother feed the baby that would make sense as Jesus blood is pure. My question is, in medical science…does the mother give blood to her baby?
One our writers (Jeff Pallansch) wrote a response to your question, thanks for asking!
Thanks for your question! When I looked into it, I found that children receive genetic information for their blood from both parents. Articles like this one from the University of Arizona report, “each biological parent donates one of their two ABO alleles to their child.” The ABO alleles are what contain the genetic information that eventually result in a child’s blood type. Everyone has two ABO alleles (one from each parent). Some types are dominant (like blood type A) and some recessive (like blood type O). The dominant types get expressed over the recessive types, unless the person has two recessive alleles in which case the recessive type gets expressed. This dominant allele can come from either the father or the mother. Furthermore, recessive alleles can be passed down to children even if they are not expressed in the parent. All this to say, a child receives genetic information pertaining to their blood from both parents. Although the theory you came across sounds interesting, I don’t think it is supported by medical science.
Theologically, as well, I am not sure that sin is ever spoken of as being passed down specifically through blood. Rather, in the Bible, blood is a symbol of a creature’s life. It is spoken of as making atonement for sin but never transmitting sin. I think of Leviticus 17:11, for example, “For the life of a creature is in the blood, and I have given it to you to make atonement for yourselves on the altar; it is the blood that makes atonement for one’s life” (NIV).
Moreover, one of the key verses on “original sin” (the innate tendency toward sin which everyone has from birth since the time of humanity’s first sin) links it with one’s mother rather than one’s father. David writes in Psalm 51:5, “Surely I was sinful at birth, sinful from the time my mother conceived me” (NIV). While this does not go into much detail, it at least shows us that the biblical authors did not press the point that sin comes only from one’s father. Although David could have easily focused on his father here, he didn’t. Rather, he placed emphasis on his mother.
Thus, I am hesitant to accept the theory’s theological presuppositions that sin is transmitted through blood and comes only from one’s father. I don’t think these points are clearly established in Scripture. In fact, Scripture seems to link both one’s father and mother to humanity’s innate tendency toward sin. How exactly is this tendency to sin transmitted? The Bible doesn’t clearly tell us. All we know is that that since the fall everyone has this tendency toward sin, but Jesus didn’t. He came as God in human flesh to live a perfect life and rescue us from it.
