I do not advocate abortion.
I also find the argument against abortion based upon human life beginning at conception to be erroneous, based upon Montanist Traducianism, rather than the Scriptural position of Creationism.
This is based upon an argument supporting creationism rather than traducianism. Jerome and Augustine favored the Creationist position. Tertullian as a Montanist favored traducianism, but he also didn’t think the soul was separate from the material, evolving from the idea that even the material didn’t exist.
Tertullian advanced some great doctrine (Trinitas, Hypostatic Union), but on the note of the soul being transferred mediately by third parties, instead of directly from God is not on track.
I didn't say you did. I'm just pointing out that it is not the breathing that makes the baby a living baby.
