What differentiates this conclusion about the moral law from other conclusions about the moral law, which everyone agrees can be rightfully legislated?
The Mosaic Law does mention miscarriages in completely unambiguous language: Exodus 21:22-25 is extremely clear that killing a fetus results in a penalty of whatever the husband thinks is fair, plus additional penalties (eye for an eye, etc.) for any other injuries which resulted to the mother. Contextually, v.12 proclaims the death penalty (or a life of exile) for anyone who murders another person and v.20 also declares this to for anyone who kills a slave (who is treated as property, but is still a living human). In my view, this is one of the strongest Biblical statements against the modern Christian position of a fetus being a human being.
I’m surprised you cite this verse, which has led many astray because of its ambiguity, as an example of complete unambiguity. To say nothing about the other difficulties, the verse nowhere states that the child died during its miscarriage. The word used simply means ‘to come out’, which is elsewhere used synonymously with being born. That the penalty set by the husband is meant to compensate for such an early birth seems to be the easiest reading.
In addition, there is very clear language all over the Bible concerning the position that life begins at birth rather than in the womb. For example, Matthew 1:20 says that the “thing” in Mary was conceived by the Holy Spirit, not the “baby” or “he” or any other word which would indicate a soul or humanity.
Oh please. Here’s the verse in Greek. Kindly point to the word which translates to ‘thing’ in your dictionary.
Job 3:11 asks about dying as one emerges from the womb
A bit hard to die unless one lives first, is it not?
Psalm 22:10, 58:3, 71:6 all use a parallel poetic structure in the Hebrew to equate the beginning of life with coming from the womb. Both Job 1:21 and Ecclesiastes 5:15 talk about the beginning and end of life: emerging from the womb then “departing” in death.
Then there are more wide-ranging teachings, such as salvation. When you believe in the work of Christ, the Bible says you are “born again”, not “conceived again” or some such. The Bible teaches that the spiritual life begins at spiritual birth, and this is an analogue for physical life at physical birth. See especially John 3:3-4 when Nicodemus even asks (sarcastically) about going back in the womb to be born again, implying that just going back into the womb wouldn’t begin a new life.
And now you’re grasping at straws. Yes, birth is an excellent metaphor for life. Those passages can be understood neither in a moral nor a legal nor a scientific sense, which is why an informed conclusion about moral, legal and scientific facts needs better sources.
The Bible does mention being “formed” in the womb many times, and I think this is one of two major planks on which Christian Fundies base their pro-Life position. But the formation of a physical body does not mean it is a human life
If the nature of the new embryonic body is not human, I struggle to see the alternatives. Could it be a plant, perhaps? A dog? A horse?
especially in light of the above teachings (and others such as: Adam was first fully formed from the dust, and only then did he become a human being when God breathed into him the Breath of Life at creation).
And if you showed up in the moment between Adam’s formation from dust and God’s life-giving breath, and just as God was getting ready to breathe and finish His work, you would cut off the limbs from Adam’s body and stab a needle into his heart, what, in your opinion, would that make you in God’s eyes?
