Though the command was given to be fruitful, multiply, and fill the earth, which typically implies the union of man and woman—an indication of finite bodies—it is conceivable that in immortal bodies, procreation could occur through a singular act of divine love, devoid of any tainted desires, allowing for offspring to exist without inheriting the mortality of their parents or experiencing death themselves. This method of generation might continue until the earth is inhabited exclusively by immortal beings, thus establishing a righteous and holy community anticipated after the resurrection of the dead. While it is possible to propose such a notion, one must acknowledge that the necessity for sustenance implies the existence of mortal forms and their limitations.
Abstinence curbs appetites. It is recorded that God created humanity male and female. God blessed them and instructed them to be fruitful, multiply, and fill the earth (Genesis 1:26-28). Some interpret this directive as indicating a physical distinction between the sexes. God also proclaimed, Behold, I have given you every seed-bearing herb upon the earth and every fruit-bearing tree: these shall be your sustenance; and to every beast of the earth, every bird of the air, and every creeping thing, I have provided green herbs for their nourishment. This is often understood as suggesting that the first humans, though different in sexes, consumed the same food as all living beings, finding sustenance there as well. Their bodies, while in certain respects immortal, possessed physical needs to avoid weakness from lack of nourishment; they would also have relied on the fruit of the tree of life to prevent aging. However, I find it difficult to believe that in such a blissful existence, the flesh would be in conflict with the spirit or vice versa, nor that they could live in dissonance without experiencing inner tranquility. Therefore, we may conclude that there was either no carnal desire at that time, or a way of life where every need was fulfilled by the appropriate use of their faculties without the influence of lustful impulses.
