Augustine of Hippo, on Gen 1:28

“And God blessed them, saying: Increase and multiply, and fill the earth, and subdue it, and rule over the fishes of the sea, and the fowls of the air, and all living creatures that move upon the earth.”

“One is completely right to ask in what sense we should understand the union of male and female before sin, as well as the blessing that said "Increase and multiply, and generate and fill the earth." Should we understand it in a physical manner or spiritually? For we are permitted to understand it spiritually and to believe that it was changed into sexual fecundity after sin. For there was first the chaste union of male and female, of the former to rule, of the latter to obey, and there was the spiritual offspring of intelligible and immortal joys filling the earth, that is, giving life to the body and ruling it. That is, man so held [the body] subject that he experienced from it no opposition or trouble. We should believe that it was this way, since they were not yet children of this world before they sinned. For the children of this world generate and are generated, as the Lord says, when he shows that we should relatively disregard this carnal generation in comparison with the future life that is promised to us.”
