That's pure conjecture...what matters is what the 'Magisterium' says now...and it is silent on the
"Personhood" of a fetus...but also strongly encourages seeking "Life", as well as "Dignity" for all living persons...ergo, the need for "Prudential Judgement" when difficult situations arise (e.g. Forced or Coerced Pregnancies...and innocent nations/citizens being unjustly attacked by others). Is this making any sense to you?
