Correct.  Embryology is new and the Church should listen to it.  Aristotle spoke about the nature of souls, which does not depend on embryology - however gastrulation fits his theory on some sort of soul being necessary for life.  We now know from neuroscience that the soul is not consciousness, so the 22 week theory at the brain must be developed to a certain extent before ensoulment must be wrong.  Soul is a life force, not a thought and the life force of a person starts when both parents DNA is in full bloom at gastrulation.  There is no fact that shows this begins at conception.  Quit parroting the discredited Vatican line, which was taken for the Church to save face on not having to admit mistakes, not based on any fact.

If you don't understand why miscarriage is a factor in when abortion can be banned than you really don't understand equal protection under law.
