I’m not ignoring the soul. The soul pre-exists the body IMO, so I don’t have any question about when the baby gets one. The baby always had one.
Asserting the soul pre-exists the body is much more problematic as that is the position of those who support reincarnation and several other heretical theologies.
There are strong arguments for the soul being created sometime between conception and birth.
IMHO, allowing the soul to be created by God and implanted to the body at birth is the least problematic and most educational regarding His Plan in the discernment between body, soul, and spirit.
