The only teaching of the Church that I seem to stumble over and can’t “get my head around” is NFP vs. barrier methods of ABC.
Now, my wife and I do not use ABC, and after she gives birth we will use NFP. Even though I cannot really understand the teaching, I am accepting it and living by it. Kind of like Peter not really grasping Jesus’ statement that they must eat and drink His flesh and blood - he just accepts it and says, “Master, to whom shall we go? You have the words of eternal life.” (John 6:68)
Here’s where I get tripped up:
Consider a married woman who must have a hysterectomy because she has cervical cancer. Post-hysterectomy, every act of intercourse is unitive only - there is no possibility of conception. Should she be having intercourse with her husband, given that the procreative and unitive aspects of the act have now been separated?
I see two ways to answer the question:
One could say that NFP allows for conception to occur even when intercourse is had solely during infertile times because it is not foolproof and if the will of God is so, conception will happen…but the same could be said when using a condom or a diaphragm, since they are not foolproof either.
Let’s pretend for a moment that NFP was 100% foolproof - practice it and there is absolutely no possibility of conceiving…does it now become sinful to practice it because there is no chance of procreation?
When I boil all of this down, I am left with two methods of separating the unitive from the procreative - both by free choice…with one being a permitted practice by the Church, the other not.

I see two ways to answer the question:
- no, because sex must be both unitive and procreative, and these two aspects must not be separated.
- yes, because even though there is no possibility of procreation, they did NOT CHOOSE to separate the two aspects of sex - this separation was forced on them via necessary surgery to preserve the wife’s life. Same would apply if the husband were sterile.
