At What Stage of Fetal Development Does an Unborn Child Receive its Soul?
"The soul is present the moment the active and passive principles of germination coalesce to form a definite entity. We therefore say that from the moment of conception, the soul is present. Our very doctrine of the Immaculate Conception of the Blessed Virgin Mary implies that doctrine. For we say that, from the moment of her conception, her soul was preserved immaculate, or free from any taint of original or inherited sin. Her soul, therefore, was created by God at the moment of her conception and long before human activity in the sense of discernible physical movement."
— Fr. Leslie Rumble (1892-1975), pioneer Catholic radio apologist
