Procreating deals with only one half of that commandment. By itself, it doesn't do anything about the "subdue the creation" part.To comply with the commandment of multiply and subdue the creation they needed to have humans offspring. The natural instinct is toward females of the species.
Wouldn't you say that a gay person who "subdues the creation" fulfils that commandment just as much as a heterosexual person who does not?
The Bible says that Eve was created because it was not good for Adam to be alone, and he had no suitable helper. It's right there in Genesis 2:18:You are reading into scripture, what it does not say, the help that Eve was created to give Adam was that of procreation, none of the animals was suited for the job, and nor it was another man.
The LORD God said, "It is not good for the man to be alone. I will make a helper suitable for him."
It goes on to say in verse 20 that Eve was created because none of the animals were suitable helpers for Adam. It says nothing about mating... which I think makes sense in the context of a story, because why would Adam and Eve, who were at that point living immortally in the Garden of Eden, need to procreate anyhow?
Adam could also not talk to the animals in a meaningful way. Personally, I think the characteristic of Eve that made her a suitable "helper" to Adam was intelligence, not just the posession of a uterus.Adam could not multiply humanity by matting them. Could he?
As I said the male and female of the creation got nothing to do with companionship, it got to do with procreation.
