This is precisely what strikes me as incongruent in Roman teaching. As you have presented it, one has great difficulty concluding that NFP is anything other than Roman approved birth control… which is why, I think, many have noted that NFP is often taught and practiced this way.
Hey workerpriest,
I used to struggle with the distinction between NFP and artificial birth control, but I understand it better now. Here’s an analogy with eating that I heard, it changed the way I thought of the issue a bit.
The natural purpose of eating is nutrition, energy for the body, sustenance, etc. There is a pleasure that comes along with eating. If you want to eat ice cream, cake, or any other tasty foods that aren’t very good for you then you have to eat responsibly and practice self control. Eat healthy foods during the week and exercise and reward yourself every few days with a good desert or junk food. We have the technology to analyze the nutritional make up of food (carbs, proteins, starch, calories,etc) so that you can decide what you should and should not eat and how much of what etc.
There was a practice of over-eating that took place in the Roman empire, mostly with upper class citizens. People would have large feasts, eat until they were full, and then go regurgitate what they just ate so that they could continue eating more. They enjoyed the pleasure that comes with eating food so much that they would bypass the natural limit allowed by their bodies in order to continue eating. This practice of eating is very far removed from the natural purpose of eating, it is completely self indulgent and contrary to the virtue temperance.
NFP is like this responsible way of dieting while birth control is like the Roman practice. NFP respects the purpose of the act, you’re playing by God’s rules. God gave a woman infertile times and we now have the technology to track those times just as we have the technology to to see what nutrients are in foods so that we can eat right, but have a treat when we’ve eaten healthy. The church doesn’t say that it’s wrong to have sex for pleasure, but you can’t alter the act for your own pleasure.
Birth control is similar to the Roman eating practice in that the person pursues the pleasure of the act without accepting the natural result of their decision to perform the act. NFP requires you to be virtuous, it requires you to be temperate and practice self control. To me this makes sense because it agrees with the Christian maxim “everything in moderation”
I once heard a priest talking about NFP, he said “ You want to know the reason why contraception is wrong? God made sex to be both unitive and procreative. Contraception separates the procreative aspect of sex from the unitive. “ When a couple using NFP wants to have sex they are respecting the purpose of the act when deciding whether or not to do it. The couple can abstain when the wife is fertile and come together when she is infertile. Since God gave a woman her fertility cycle, choosing to come together when she is infertile is not the same as ABC because the procreative aspect is a deciding factor; it has a bearing on their decision.
