My elect, whom I delight in. God simply says my soul to mean Himself in language men can relate to.God says He has a soul Isaiah 42:1. He could not have a person without one because the soul is the person of anyone. Of course His soul is much more glorious and holy than ours, but it is still His person/being who He is. Jesus preexisted and the soul person He was then had to be the same soul that God placed in Mary's body. Jesus was not two persons. The Holy Spirit is distinct from the persons of the Father and the Son. That is correct.
God does NOT have a Person.
God did NOT place a soul in Mary's body; The soul of Jesus was formed after His conception.
