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
Far be it then from us to believe that the couple that were placed in paradise would have fulfilled through this lust, which shamed them into covering those organs, the words pronounced by God in his blessing: “Increase and multiply and fill the earth.” For it was only after man sinned that his lust arose; it was after man sinned that his natural being, retaining the sense of shame but losing that dominance to which the body was subject in every part, felt and noticed, then blushed at and concealed that lust. The nuptial blessing, however, whereby the pair, joined in marriage, were to increase and multiply and fill the earth, remained in force even when they sinned. Yet it was given before they sinned, for its purpose was to make it clear that the procreation of children is a part of the glory of marriage and not of the punishment of sin.
