The first citation is an account of the creation of one male human being. The second one is a summary of the creation of humanity. The third citation is an account of the creation of the first female human being. The third citation would seem to imply that if God created specifically a “woman,” she would have female sex organs and secondary sexual characteristics (e.g., typical female figure including breasts, shallower and wider pelvic girdle, etc.) It would be utterly illogical for God to create such a being and bring her to another human being who had no male reproductive system or secondary male sexual characteristics.
Also, according to Genesis, God did say after creating the first two people: “Be fruitful and multiply and spread over the earth, etc,” so I think that the reproductive systems were part of His original design. Since He decided to rest on the seventh day after creating people, I’d think He’d foresee that if He were to just cast parents into a deep sleep, take a rib and voila–you have offspring–people couldn’t obey that command of His. Plus, if they were to populate the earth via the second method, He’d always be doing human reproduction! The creation of Eve was just a way to jump start the female gender of the species.
If on the other hand you believe in evolution, you can readily see that anything above amoebas in the animal kingdom reproduce sexually. All higher animals have sexual organs, so “male and female” He at least designed them, too.
No, I think He wanted us (and all His creation) to have a share in His creative process. And for a complex organism such as a human being, that would require sexual reproduction. He created the apparatus for that right at the start, and it was good. He also infused our personalities with an aspect of sexuality which is not the same thing as sexual expression, but an acknowledgement of our identity as men or women in addition to all the other things we are. That’s good, too.
Original sin is what gave us a propensity to use sex selfishly and sinfully. We’re the ones who loused it up. Original sin gave us a propensity to louse everything up. That’s called concupiscence. Via concupiscence, we tend to mess anything up, from elements of nature to our entire social structure. The point of the original sin issue is this–the first humans were tempted to eat the apple so that they could become like God. That would require the ability to foresee the results of actions, the indepth knowledge of every ethical issue that any one act could touch on. We just don’t have that capacity. So voila–the propensity to sin.
Sexual intercourse when engaged in in the appropriate setting (marriage) with the proper reasons (expression of love between husband and wife and being open to the possibility of the creation of new life) is still good. Expression of our genders in our personalities (sexuality) is still good, even if we’re celibate. It’s all still good. We just have to be careful not to louse it up!
