God's causality. The Roman Catholic Church teaches that "every spiritual soul is created immediately by God - it is not "produced" by the parents, and also that it is immortal..." Humans have, however, free will and thus control over their own existence, as much as they are responsible for the act of procreation. Traducianism contradicts the concept of the indivisibility of the soul. If the souls are incapable of division, then it is impossible for the soul of the child to be derived from the souls of the parents. But this is a merging and creation by two souls, and God would also have to divide himself in order to create a new one through his own substance. Also, in the Nicene Creed, the Son was generated, not created, and the Holy Ghost proceeds from both the Father and the Son. The weakness of traducianism, to many theologians, is that it makes the generation of the soul dependent of the transmission of matter. Presbyterian theologian Charles Hodge held that since the nature of the soul is immaterial it could not be transmitted by natural generation. Traducianism proceeds on the unproven assumption that God only works in a managerial manner after completing the creation of the world. Louis Berkhof points out that God continues to work immediately both in the performance of miracles and in some parts of the work of redemption.
