And God blessed them, and God said unto them,
Be fruitful, and multiply, and fill the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moves upon the earth.
All Commentaries on Genesis 1:28 Go To Genesis 1
Augustine of Hippo
AD 430
If one should ask why it was necessary that a helper be made for man, the answer that seems most probable is that it was for the procreation of children, just as the earth is a helper for the seed in the production of a plant from the union of the two. This purpose was declared in the original creation of the world: “Male and female he made them. And God blessed them and said, ‘Increase and multiply and fill the earth and subdue it.’ ” This reason for creation and union of male and female, as well as this blessing, was not abrogated after the sin and punishment of man. It is by virtue of this blessing that the earth is now filled with human beings who subdue it. Although it was after the expulsion of the man and woman from paradise that they came together in sexual intercourse and begot children, according to Scripture, nevertheless I do not see what could have prohibited them from honorable nuptial union and “the bed undefiled” even in paradise. God could have granted them this if they had lived in a faithful and just manner in obedient and holy service to him, so that without the tumultuous ardor of passion and without any labor and pain of childbirth, offspring would be born from their seed. In this case, the purpose would not be to have children succeeding parents who die. Rather those who had begotten children would remain in the prime of life and would maintain their physical strength from the tree of life that had been planted in paradise. Those who would be born would develop to the same state and eventually, when the determined number would be complete, if all live just and obedient lives, there would be a transformation. Thus without any death their natural bodies would receive a new quality since they obeyed every command of the spirit that ruled them. With the spirit alone vivifying them, without any help from corporeal nourishment, they would be called spiritual bodies. This could have been if the transgression of God’s command had not merited the punishment of death. –.
