YOUCAT Question n. 63 - From where does man get his soul?

(Youcat answer) The human soul is created directly by God and is not “produced” by the parents.      

A deepening through CCC

(CCC 366) The Church teaches that every spiritual soul is created immediately by God - it is not "produced" by the parents - and also that it is immortal: it does not perish when it separates from the body at death, and it will be reunited with the body at the final Resurrection (Cf. Pius XII, Humani generis: DS 3896; Paul VI, CPG § 8; Lateran Council V (1513): DS 1440).    

Reflecting and meditating 

(Youcat comment) 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 that 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.

(CCC Comment)

(CCC 367) Sometimes the soul is distinguished from the spirit: St. Paul for instance prays that God may sanctify his people "wholly", with "spirit and soul and body" kept sound and blameless at the Lord's coming (1 Th 5:23). The Church teaches that this distinction does not introduce a duality into the soul (Cf. Council of Constantinople IV (870): DS 657). "Spirit" signifies that from creation man is ordered to a supernatural end and that his soul can gratuitously be raised beyond all it deserves to communion with God (Cf. Vatican Council I, Dei Filius: DS 3005; GS 22 § 5; Humani generis: DS 3891).
