Intent is not a part of contraception. From the Catechism:
2399 The regulation of births represents one of the aspects of responsible fatherhood and motherhood.** Legitimate intentions on the part of the spouses **do not justify recourse to morally unacceptable means (for example, direct sterilization or contraception).
So, there it is. Intent is not a sufficient reason to permit contracepted sex, just as it says in HV.
That refers to intent in regard to suppressing fertility.
Notice HV says:
15. On the other hand, the Church does not consider at all illicit the use of those therapeutic means necessary to cure bodily diseases, even if a foreseeable impediment to procreation should result there from—provided such impediment is not directly
intended for any motive whatsoever. (19)
YOU are reading into one paragraph of HV something that is not there - that a couple can have sex while temporarily contracepted due to medical treatment. HV allows the treatement; not the sex.
Where does HV say that? It does not say what you claim. HV says:
***Unlawful Birth Control Methods
*** Therefore We base Our words on the first principles of a human and Christian doctrine of marriage when We are obliged once more to declare that the direct interruption of the generative process already begun and, above all, all direct abortion, even for therapeutic reasons, are to be absolutely excluded as lawful means of regulating the number of children. (14) Equally to be condemned, as the magisterium of the Church has affirmed on many occasions, is direct sterilization, whether of the man or of the woman, whether permanent or temporary. (15)
Similarly excluded is any action which either before, at the moment of, or after sexual intercourse, is specifically intended to prevent procreation—whether as an end or as a means. (16)
It refers to contraception, not to medical therapy.
Of course, based on the natural law and Magisterium, you must distinguish between a couple that is permanently sterilized (NOT for the purpose of birth control), through medication or birth, and one that has fertility temporarily masked through medical treatment (which is allowed). In the first case, sex is permitted b/c the couples are using their sexual organs in the proper fashion where fertility is impossible. The Natural Law permits this because that is the function of sexual organs.
This is your private teaching. Where has the Church stated this?
Specifically, where has She said one may engage in sex after surgery that leaves one sterile but may not engage in sex while one is temporarily sterile?
Where the treatment is therapeutic and temporary, that means the body is being contracepted.
No, that means one is being treated. Contraception involves the intent and/or means to alter the marital act to suppress normal fertility to space children.
There is a difference between temporary contraception and sterility. Sterility is a biological condition, not contraception.
This makes little sense. Medical therapy that leaves one sterile, no matter the amount of time, is a biological condition too.
With temporary contraception, as permitted by the Natural Law and HV 15, one cannot have recourse to sexual intercourse, NO MATTER WHAT THE INTENT IS.
This is false and you have not supported your case. At least I have linked to a faithful priest that contradicts your position. You only offer your opinion.
Also, your choice of words is not accurate. The medical use of the word contraception is not always equal to the theological use of that word.
We all agree the intent to “contracept” is intrinsically wrong. What we do not agree on is calling medical treatment “contraception”.
You may not find a sentence that says this, but look at the NFP physicians’ above, read the documents, and you can piece it together. The Magisterium does not, and need not, speak to every permutation. And Catholic morality would never allow contracepted sex that is necessarily abortifacient where a conception occurs.
We will not find the sentence because that is not the teaching.
