The “Jewish breath = personhood” claim and the “Israelites must have known ancient abortifacients” claim don’t actually touch the biblical question, because neither one gives you a biblical definition of personhood or a biblical moral category for abortion. They’re historical observations, not theological foundations — and the apostles never build doctrine on either one.I might note on this matter that a Jewish understanding is that personhood is linked to life and occurs when the first breath is taken based on the creation of Adam, who was made by God but did not become a living being until God breathed life into him, after his formation.
And while scripture is silent on the question of abortion, it is known by science and those who are aware of ancient records beyond the Bible that there used to be a now extinct plant that could be used to initiate an abortion in the Mediterranean region. Or do you believe that the ancient Israelites were the only group in the region that did not know about this plant?
Yes, the Israelites surely knew about ancient abortifacients — but that fact does nothing to establish a biblical moral category. The existence of a plant, herb, or technique in the ancient world never determines whether Scripture calls an act righteous or wicked. The Bible’s ethics are built on God’s revelation, not on regional medical knowledge.
