I hate it when fundamentalists ignore the Old Testament when it suits them.
Whoever was behind this so-called 'personhood' amendment is ignorant of what the Bible has to say on the subject. It is nearly impossible to be familiar with the Old Testament and not recognize the compelling connection the sacred texts make between human life, or the life of any animal, and blood. It is clear beginning with the Book of Genesis and the significance of blood runs throughout.
"But flesh with the life thereof, which is the blood thereof, shall ye not eat. And surely your blood, the blood of your lives, will I require; At the hand of every beast will I require it. And at the hand of man, even at the hand of every man's brother, will I require the life of man. Whoso sheddeth man's blood, by man shall his blood be shed: For in the image of God made he man." Genesis 9:4-6
From a Biblical point of view, life is not present where there is no blood. Since the heart of a human embryo does not develop and begin to beat until about the sixth week following conception, there is clearly no human life present until then. Accordingly, based upon Biblical authority, human life does not begin at conception. It is un-scriptural to think of a fertilized egg as being a separate person. Until a fetus has a functioning circulatory system suffused with blood, which is life as the Bible defines it, there is no 'person.'
