I heard a scientific argument regarding the scientific feasibility of the Christian Virgin Birth recently. here it is:
At the appointed time Jesus came, born of a virgin. Don’t laugh; it’s true, and medical documentation proves the importance. The blood of the child in the mother’s womb is 100% the blood of the father. Thus if one chooses to believe the true gospel, that person believes in the virgin birth. It was prophesied in several places in the Old Testament. The virgin birth meant that the blood in Jesus Christ’s body was not from the creation of Earth and creation of Adam. It was sinless, heavenly blood.
I will not ascribe it to anyone in particular, even though I know who this is. I use this as an example of where faith goes astray. It does so through belief, namely the belief that some preacher man knows what the heck he is talking about.
As children learn in basic reproductive biology, a sperm and an ovum join to create a cell which has half of the DNA of the father and half of the mother. The first cell has this DNA, and then the next, and the next. If this is done sufficiently often without interruption a viable zygote forms and eventually a baby. This baby may “take after” his mother or his father but is not identical to either of them. His blood is his blood, each and every cell in it has DNA from both mother and father.
“The blood of the child in the mother’s womb is 100% the blood of the father.” Where this comes from I do not know. Maybe someone misheard a statement that had some truth in it and then took it and ran with it. A scientist would have looked for confirmation. A paper containing this “fact” would get reviewed and corrected. But preachers don’t have such a support system; they only have divine guidance.
Belief is easy when it supports what one wants, but that doesn’t make it so.
And, the Bible is full of claims for “blood magic” that are similar to this. There are blood sacrifices. People are required to not eat meat with blood in it. Blood can carry sin with it. Children can inherit “bad blood” from their parents. Women are “unclean” while menstruating. All of this “magic” has been shown to be mistakes (along with all other magic), so why is it still prominent in the Bible? Why do some insist that blood magic is real because “the Bible tells me so.”
