But if intent is amoral, whatever you do to accomplish it is amoral as well.
Intent is clearly important, but it’s merely one part of determining the moral value of an action. There is intent to use something appropriately. And there is intent to bring about a result. They are two, separate intents. One not necessarily overlap the other.
I dare to say, you are mistaken. Natural law is all about intentions.
Everything created has some use in the nature. To use something morally, during usage you have to *intend *the result for which the thing is created. And, since theology up to 19th Century observed procreation as the only usage of sexual act, contraception was forbidden. And this is the problem for us today.
NFP is, by this logic, as contraceptive as other techniques of fertility control.
Intending to ejaculate into a vagina, where semen gets into the vagina, is precisely following the purpose of the penis. With or without procreation. In a single instance act of sex, if the penis does not ejaculate inside of the vagina, its purpose has been thwarted. As you pointed out, you have to intend ejaculation into a vagina—
not a fertile vagina. (More on this below). The further intention of procreation does not follow necessarily. That is an intention that applies to marriage in a larger way, not to sex as a single act.
You can intend to use a penis, by itself, properly while not necessarily intending the further result of conception. I can use my hand without thwarting its purpose of grabbing, holding, and touching by masturbating with the further intention of orgasm. But my further intention of orgasm is wrong because the purpose of the orgasm is to get semen into a vagina. I can use my hand with its purpose in mind to work to build for the further intention of making money. This would be entirely licit, as the use and the further intention are proper. But I could also use my hand improperly, by say, mutilating it for someone else’s pleasure, for money. The goal of making money, of supporting myself, is good. The intentional use of the hand is bad, as it thwarts its inherent purpose. The goal of creating a stable family is good, but the use of contraception in that it intentionally stops the semen from getting into the vagina is bad.
Contraception serves two purposes. One, to stop procreation. Two, to stop semen from entering into the vagina—or with other birth control methods, to prevent, by outside force, the semen making it to the egg/fertilize the egg, as by its purpose. NFP serves one, the first, and it does nothing like the second. It does not prevent fertilization in any conceivable way. The act of having sex with your wife without contraception in that moment does not thwart the purpose of any instrument of the body. The first purpose, holding off procreation, is licit and can be morally justified; it can be an act of prudence and love. The second is not. These two things are not the same.
These are wise words. But since most homosexuals would not achieve fulfillment with heterosexual spouse, further questions regarding their religious life emerge.
But they likely would (or certainly argue that they do) achieve some sort of fulfillment with a homosexual partner. Intention is not the only thing that matters with respect to sexual ethics (or any ethics for that matter). That’s all I was getting at. After all, a homosexual couple who
really wants children and has intercourse every day to bring that about is hardly committing a licit act. Because the means of bringing about that further good intention (which, I might add, it *is *a good intention) is a misuse of the particular objects’ (particularly their penises) purposes.
One simply has to stress that during act, if you wish not to beget, you are against the natural law the way stoic Catholics claimed. If one has sex on infertile day, because it is infertile, he does so with intent to have intercourse without begetting. And since intercourse is only for begetting, such sex is sinful.
This whole claim “intercourse is only for begetting” is a faulted premise to begin with. And perhaps something you ought to work through. Again, I think you are reading the Church fathers in a totally dangerous direction. And even if they did say something similar to this, you are dodging the issue by ignoring the argument. For example, I doubt you would say that a couple who chooses to have sex when the woman is infertile (by date or condition), but intended children all the same, is committing a sin. If intercourse is
only for begetting children, as you claim here, they would not be committing an act that would beget, as has been pointed out, by its very nature. Following your reasoning, they would be committing sin; they would just be masturbating into one another.
Taken further, I think it could easily be argued that if I intend for a future something to occur, despite knowing that it is by its very condition impossible, I am not intending it at all. Intending to make a table by swimming around in the ocean is not intent to make a table. It is by its nature impossible to make a table by swimming around in the ocean, even if that’s what I intend to do by swimming. To say that I intend to make a child by having sex with a woman who happens to be infertile (that I know about, but intend all the same) is quite similar. Unless you think a woman who happens to be infertile that week is praying beyond all hope that her infertile condition would somehow, though miracle I guess? create a new life. Of course, she could probably intend conception by swimming around in the ocean as well; that’s just as likely to happen after all. This, I think as well, is absurd. Unless you are willing to argue that couples may not have intercourse if they are infertile.
