The human soul is created directly by God and is not “produced” by the parents. [366-368, 382]
Man’s soul cannot be the product of an evolutionary development out of matter or the result of a generative union of the father and mother. With every man, a unique, spiritual person comes into the world; the Church expresses this mystery by saying the God gives him a soul, which cannot die; even if the person loses his body in death, he will find it again in the resurrection. To say,
‘I have a soul,” means that God created me not only as a creature but as a person and has called me to a never-ending relationship with him.
