Here is Augustine on the creation of the human race:
"Therefore, God created one sole individual, not that he was meant to remain alone deprived of human companionship, but in order that the unity of society and the bond of harmony might mean more to man, since men were to be united not only by the likeness of nature but also by the affection of kinship. God did not even wish to create the woman who was to be mated with man in the same way that He created man, but, rather, out of him, in order that the whole human race might be derived entirely from a single individual."*
* City of God, Book XII, Chapter 22.
